Problems with compiling Filesystem library on Solaris
by Barak Simon 08 Oct '04

08 Oct '04

Hi, I get the following error from the Filesystem library when building boost 1_31 on Solaris with sunpro compiler: "/db/pub/eq/build/src/boost_1_31_0/boost/iterator/iterator_facade.hpp", line 622: Error: Could not find a match for boost::iterator_core_access::equal<boost::iterator_core_access::Facade1, boost::iterator_core_access::Facade2>(const boost::filesystem::directory_iterator, const boost::filesystem::directory_iterator, boost::is_convertible<boost::filesystem::directory_iterator, boost::filesystem::directory_iterator>). "/db/pub/eq/build/src/boost_1_31_0/libs/filesystem/build/../src/operations_posix_windows.cpp", line 176: Where: While instantiating "boost::operator==<boost::filesystem::directory_iterator, boost::filesystem::path, boost::single_pass_traversal_tag, boost::filesystem::path&, int, boost::filesystem::directory_iterator, boost::filesystem::path, boost::single_pass_traversal_tag, boost::filesystem::path&, int>(const boost::iterator_facade<boost::filesystem::directory_iterator, boost::filesystem::path, boost::single_pass_traversal_tag, boost::filesystem::path&, int>&, const boost::iterator_facade<boost::filesystem::directory_iterator, boost::filesystem::path, boost::single_pass_traversal_tag, boost::filesystem::path&, int>&)". "/db/pub/eq/build/src/boost_1_31_0/libs/filesystem/build/../src/operations_posix_windows.cpp", line 176: Where: Instantiated from non-template code. It looks suspiciously similar to bug "[ 976241 ] Compiler error for tokenizer on Solaris" from 2004-06-20, with the difference that I am using version 5.3 of sunpro rather than 5.5. My guess is there must be some flag/macro/workaround I am missing (as this specific library is supposed to be portable to many OSs and compilers) , but have no idea what that may be. Any suggestions would be a blessing.

Typelists
by Puverle, Tomas (IT) 07 Oct '04

07 Oct '04

What is the status of typelist support in boost? I read through a backlog of email in the archives but the last ones are from ~2002. Grepping through the source of 1.31.0 for (typelist | type_list) reveals some in the detail namespace for python, but that's all.

uBLAS lapack bindings

Hello, I have a question about using uBLAS/LAPACK bindings on AIX 5.1 and VA6. I am doing something like the following: matrix<double> matrixTwo(200,200); identity_matrix<double> identMatrix = identity_matrix<double>(200); int inverseInfo = gesv(matrixTwo,identMatrix); I am getting the following errors: line 102.36: 1540-0130 (S) "matrix_traits<boost::numeric::ublas::matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::a\ llocator<double> > > >::size1" is not declared "/npd/delliott/boost/numeric/bindings/traits/matrix_traits.hpp", line 102.7: 1540-0700 (I) The previous message was produced while processing "boost::numeric::bindings::traits::matrix_size1<boost::numeric::ublas::matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::allocator<double> > > >(matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::allocator<double> > > &)".

After I have switched that to the explicit "using" statements I could also switch back to your default "user.hpp". Perhaps I can ask one more question about this strange behaviour, just because I want to understand why: I try to use my own string class, which is inherited from std::string. Defining "VC6_STUPID_BEHAVIOUR" in the example code below compile and run the code successfuly, using the expanded name leads to following compiler error: error C2614: 'MyCString' : illegal member initialization: 'string' is not a base or member You know WHY??? Also because of the same compiler error in VC6 or is there something else wrong. On Solaris and HP-UX it works fine in every combination. // vvvvvvvvvvvvvvv snipp vvvvvvvvvvvvvvvv #include <string> #include <iostream> #ifdef VC6_STUPID_BEHAVIOUR using std::string; # define std_string string #else # define std_string std::string #endif class MyCString : public std_string { public: MyCString(const char *s_); : std_string(s_) { std::cout << "\"" << *this << "\"" << std::endl; }; }; int main (int argc, char *argv[]) { MyCString s(argv[0]); return 0; } // ^^^^^^^^^^^^ snipp ^^^^^^^^^^^^

boost install with gentoo issue?
by dave＠superelite.net 06 Oct '04

06 Oct '04

Well, more likely my mistake, ive been up awhile.. I installed the boost libs onto my gentoo machine with emerge. I then added -lboost_regex to my linker flags..thats it. When I run my app, it hangs, I think when waiting on pulling data of off a UDP socket. Though I cant tell, I'm about to crash and its been one of those days. But I do know everything is back to normal when I take -lboost_regex out of the flags again. I know I'm awfully vague due to lazy/tiredness, but does this ring a bell with anyone? I've installed boost the traditional way (bjam) on other linux distros before without any issue, but ive never tried emerge before. I dont know if this has something to do with it, or i am somehow missing something really obvious.. Thanks for bearing with me, Dave

Hello, Are the uBLAS LAPACK bindings for general matrices or for any type of matrix? Do they have to use a particular type of storage? This is how it appears in the code. Would anyone like to talk about how other types of matrices might be used? Thank you, Dan

uBLAS problem under Borland C++builder
by 徐亮 05 Oct '04

05 Oct '04

Hi Boost people I'm starting with uBLAS matrix class under Borland C++ builder. I copied a sample from boost document and complied it. There are always mistakes in "traits.hpp". I tried again in VC and no problem occured. I just wonder what's wrong with BC. I have copied the boost dir into BC's Include dir and have added it in Project->Options->Directories. Here's my copied code: #include <boost/numeric/ublas/matrix.hpp> #include <boost/numeric/ublas/io.hpp> int main () { using namespace boost::numeric::ublas; matrix<double> m (3, 3); for (unsigned i = 0; i < m.size1 (); ++ i) for (unsigned j = 0; j < m.size2 (); ++ j) m (i, j) = 3 * i + j; std::cout << m << std::endl; } Thanx

Problem compiling Windows C++ code wit regex
by arno.schaefer＠sqs.de 05 Oct '04

05 Oct '04

Hi all, I try to compile some older C++ Code with your RegEx class and got in some source code problems with some ambiguity I believe between the std and the global namespace. I followed the include hierarchie starting from "boost/regex.h" down to "boost\config\stdlib\dinkumware.hpp" and here was my first problem, why this stdlib implementation was selected, I don't think, that this is the normal implementation for "VC++ 6.0 SP6" what I am using!? The errors I got are located in some windows system header and look like this only in one source file: : d:\programme\microsoft visual studio\vc98\include\objidl.h(9901) : error C2668: 'memset' : ambiguous call to overloaded function d:\programme\microsoft visual studio\vc98\include\objbase.h(435) : error C2668: 'memcmp' : ambiguous call to overloaded function d:\programme\microsoft visual studio\vc98\include\objbase.h(459) : error C2668: 'memcmp' : ambiguous call to overloaded function Error executing cl.exe. Any idea what kind of define can cause this problem? I visit every included headerfile and look also in the expanded preprocessor code (*.i file) and didn't see exactly what happend, so have somebody an idea? Thanks for your help Arno

C++ Parsing - oops
by Foster, Gareth 03 Oct '04

03 Oct '04

Hello John, Joel, I didn't mean to knock your work with that last email John, it might have come across badly, it was meant more as a compliment to spirit and a reference to the fact that it 'appears' to fit the bill for what I want to do better, not to bash regex, I like regex too. For the record it needn't be 'perfect' indexing of the C++ code, I don't mind if I get two hits for the same classname for example. I used regex for a tool to index the C++ and C files themselves, so I could quickly search for file names using regular expressions, it works great! So thank you both, no offence caused I hope. So, will spirit be the best way then? Glad to hear its already a part of boost btw, congratulations mate. Cheers!

It depends what you want to do: if you want to use a "real" C++ parser then you will also have to preprocess the code (including the includes) and then parse the code. In theory this gives you a "perfect" result, but only if you know what include paths to use, and what predefined macros should be set (think about conditional code blocks). Regexes on the other hand, don't require you to preprocess the code, but can get confused by macros and the like. So you have to choose the way that best meets your expectations, and live with the defects either which way ;-) To solve your problem BTW, why not scan through the file for line starts (keeping count obviously!), and at each line start see if it's also the start of the regex you are interested in (one that matches a class definition for example), if you do this don't forget to either: prefix your expression with \A or Pass the match_continuous flag to regex_search, Either will anchor the search at the start of the line you are checking, and prevent the whole text being searched.

Re: Boost:regex and C++ Parsing - Spirit!

Wow, I just read through the 1st few pages of the spirit docs, and I can safely say, that is as close to naked women as C++ code will ever be, its such a sexy idea. One library, and you can parse any sort of config file, code or anything! Amazing. Well, any lingering desire to use regex for my pet project has now left the building, I can't wait to have a play with spirit. When will it be a part of boost? Is it worth installing it seperately (I'd hate to do that and have a new boost appear the day after). Also, reading this made up my mind that I should get a nice magazine about STL and C++ matters, can anyone recommend one (UK based preferable, but all sugestions welcome). Interetsing stuff, thank you all! Gaz

Below is the code, which I am trying to run. #include <boost/multi_array.hpp> class Array : public boost::multi_array<double,2> { public: Array (void) : boost::multi_array<double, 2> () {} Array (const int nrow, const int ncol) : boost::multi_array<double, 2> (boost::extents[nrow][ncol]) {} Array (const Array& other) : boost::multi_array<double, 2> (other) {} ~Array (void) {} Array& operator= (const Array& rhs) { if (&rhs != this) { boost::multi_array<double, 2>::operator= (rhs); } return *this; } }; /* class Array */ I guess that I forget to provide some information to my derived class, but I cannot find which one. Is there a way to simply inherits from boost::multi_array? Many thanks in advance, Thomas

[serialization1.32/vc7.1]: What's wrong with this class??
by Francis ANDRE 02 Oct '04

02 Oct '04

Hi I got a access violation on 0x00000000 with the class DDD but I cannot figure out what's wrong When the symbol NO_EXCEPTION is defined, the member acccode is set to an instance of ACCCODE and the serialization is working fine. But when this symbol is undefined, one gets the exception. I am suspecting the input serialization to bypass the loading of the member FIELD* field (which is following the "acccode" member) which leads to an exception when the next member DISP* disp is loaded but I have no way to check it out any idea??

Boost 1.30 with g++ 3.4
by Ben Hutchings 02 Oct '04

02 Oct '04

I have an existing body of code using some parts of Boost 1.30 (Bind, Function, Regex, Thread, and some utilities) and compiled using VC++ 7.1 on Windows. I now need to build with g++ 3.3 or 3.4 on Linux as well, and for various reasons I would prefer to use 3.4. Boost 1.30 predates g++ 3.4 by some way and I know that it won't all work without changes. However, neither will 1.31, and 1.32 has still not been released. I would rather not upgrade to either of these in case they break the existing Windows build. Are there any known bugs or other problems in the above-mentioned libraries from Boost 1.30 when used with g++ 3.4, and if so, any known fixes for them? (Assume I'm using Boost 1.30.2 - I might still have 1.30.0 but upgrading to 1.30.2 should be low-risk.) Ben.

Are BOOST_BUILD_PATH && BOOST_ROOT necessary?
by Steven T. Hatton 01 Oct '04

01 Oct '04

>From reading the documentation on boost.org, I have gotten the impression I don't need to set $BOOST_BUILD_PATH and $BOOST_ROOT. I'm more than a little confused about how I should use the boost libraries. Part of this comes from the fact that it is not clear to me exactly where the demarkation is between using the build system to build boost, and using it to build my own programs. Some of my confusion comes from the appearant change in configuration requirements described in the documentation. It is suggested I don't need the environment variable used with earlier releases. One of these variables is $BOOST_ROOT, which the documentation used as an example of how to build boost. That example was exactly what I successfully (I believe) build the libraries with. I'm using SuSE Linux 9.1 on a P4 box. Some basic questions are these: When I downloaded and built boost, I first fetched the source for bjam. This is the name of the file I downloaded: boost-jam-3.1.10.tgz It compiled quite nicely, and I copied the resulting bjam jam mkjambase and yyacc to a location in my path. Are there anything other things such as configuration files I need to reside with the binary executables? Are there necessary configuration file that I need to have visible to these programs, even if they are not colocated? I then build boost with the command: bjam --prefix=$BOOST_ROOT "-sTOOLS=gcc" install after setting my BOOST_ROOT the way I wanted it. That resulted in two directories being placed in $BOOST_ROOT/ one is called $BOOST_ROOT/include/ the other is called $BOOST_ROOT/lib/. Under $BOOST_ROOT/include/ I have <path>/boost-1_31/boost/ which contains dozens of header files. I added $BOOST_ROOT/include/boost-1_31 to my $INCLUDE_PATH, and $BOOST_ROOT/lib to my $LIBRARY_PATH and $LD_LIBRARY_PATH variables. Is this the correct way to configure my system to use boost? Is there anything else I need to do in order to compile my programs against the boost headers and libraries? Will the boost libraries work as well as other, comperable libraries using autotools rather than bjam? Are there any special accommodations I need to make in order to use boost with the gnu build tools? Do I need to do anything special to use boost with bjam that does not involve placing files in my current project directories? For example, do I need to provide a global configuration file of some kind? Is it a preferred option, even if not strictly required? There is much remaining in the source directory where I compiled boost. Is that something I need to also put in an accessible place on my system? If so, what so I need to put where, and how to I modify my environment variable to facilitate its use? -- Regards, Steven

BOOST_CHECK_CLOSE apparent misbehavior
by Ross Boylan 01 Oct '04

01 Oct '04

I get the following error Specification_test.cc(22): error in "specsimple": difference between spec(i, j){0.206788} and results[k]{0.206788} exceeds 1e-05% The numbers agree to all printed digits. I get a maximum relative error (assuming the printed values are rounded from extremes)*(see footnote) of .000001/.206787 = 4.8e-6 < 1e-5. Even doubling this is under the tolerance. As I read the documentation, this should pass. 1e-6 tolerance produces a lot more discrepancies; 1e-4 says they are all OK. Have I misunderstood something, or is something funny going on? In particular, the "%" after "1e-5" in the error message suggests the tolerances are supposed to be in percentage terms, i.e, 1e-5 implies a real tolerance of 1e-7. That would explain things, but I see nothing in the documentation to suggest the tolerance value is a percent. (Well, the docs do say the tolerance can be an integer.) The relevant line is BOOST_CHECK_CLOSE(spec(i, j), results[k], tol); All relevant quantities are doubles. It may be relevant that the program under test includes <cmath>. Debian package libboost-dev 1.31.0-7 on an Athlon system. # g++ --version g++.real (GCC) 3.3.4 (Debian 1:3.3.4-6sarge1) Linux kernel 2.4.26 * In fact, the results value is coded as 0.2067880 in the program, so my calculation likely gives double the possible discrepancy.
