F6U2 anachronisms warnings
by ljohrixxx 16 Jun '03

Hello, I get the Anacronism warning from the file is_convertible.hpp line: 293 BOOST_TT_AUX_BOOL_TRAIT_DEF2(is_convertible,From,To, (::boost::detail::is_convertible_impl<From,To>::value)) The warning is: /usr/vobs/ThirdParty/boost/boost_1_30_0/boost/type_traits/is_convertib le.hpp", line 239: Warning (Anachronism): Type names qualified by template parameters require "typename". "/usr/vobs/ThirdParty/boost/boost_1_30_0/boost/type_traits/is_converti ble.hpp", line 239: Warning (Anachronism): Type names qualified by template parameters require "typename". I am using Forte6 U2 compiler on Solaris. Can someone please shed light on what does it mean? I get a whole bunch of similar warnings from many other boost headers. -LJ

Solution for (some) Compilation Problems with Sun Forte 6.2
by Adalbert Perbandt 16 Jun '03

16 Jun '03

Hi there, a colleague of mine tried to build the Boost::filesystem library (from Boost 1.30.0) under Sun SPARC Solaris7 with the Forte6.2 aka Sun Workshop5.3 compiler and got this failure: >> Assertion: (../links/init.cc, line 972) while processing /opt/boost_1.30.0/boost/type_traits/alignment_of.hpp at line 45. He investigated this problem and found out that defining the preprocessor macro BOOST_NO_INCLASS_MEMBER_INITIALIZATION would solve this. So we changed the boost/config/compiler/sunpro_cc.hpp at line 33 as follows: # if (__SUNPRO_CC <= 0x530) || !defined(BOOST_STRICT_CONFIG) # define BOOST_NO_INCLASS_MEMBER_INITIALIZATION Now we can compile the filesystem library successfully. Could please one of the experts comment on this change or maybe include this in the next release? Regards, Adalbert Perbandt.

Newbee: Build/Installation Questions
by Adalbert Perbandt 16 Jun '03

16 Jun '03

Hi there, I'm still uncertain how to properly build and install boost libraries under Solaris 7. I unpacked the boost_1_30_0.tar.gz file and ran from the boost_1_30_0/libs/test/build directory: $ jam -sTOOLS=sunpro -sBUILD="debug release" \ -sALL_LOCATE_TARGET=/opt/boost_1.30.0 This created some of the lib files below /opt/boost_1.30.0/libs/test/build/bin/... Not all of them because in release mode compiling the file boost_1_30_0/libs/test/src/unit_test_log.cpp failed several times: [...] sunpro-C++-action /opt/boost_1.30.0/libs/test/build/bin/libboost_test_exec_monitor.a/sunpro/release/runtime-link-dynamic/unit_test_log.o Assertion failure in prep_dot >> Assertion: (../links/prepexpression.cc, line 560) while processing ../src/unit_test_log.cpp at line 301. CC -c -DNDEBUG -fast -O4 -xtarget=generic -features=rtti -features=except -I"/opt/boost_1.30.0/libs/test/build" -I"/home/hwadm/Boost/boost_1_30_0" -o "/opt/boost_1.30.0/libs/test/build/bin/libboost_test_exec_monitor.a/sunpro/release/runtime-link-dynamic/unit_test_log.o" "../src/unit_test_log.cpp" ...failed sunpro-C++-action /opt/boost_1.30.0/libs/test/build/bin/libboost_test_exec_monitor.a/sunpro/release/runtime-link-dynamic/unit_test_log.o... [...] Line 301 and around in this file look so: //____________________________________________________________________________// unit_test_log& unit_test_log::operator<<( checkpoint const& cp ) { if( m_pimpl->m_entry_in_progress ) m_pimpl->set_checkpoint( cp ); // LINE 301 return *this; } //____________________________________________________________________________// I cannot see any complexity here that could lead to an assertion. As I learned from the Boost Users Mailinglist archive such assertions seem to be common problems with Sun's forte 6.2 and 7 compilers. O.k. When the build above was finished I got at least the libs. built in debug mode obvisously completely installed below /opt/boost_1.30.0/libs/test/build/bin/<libs>/sunpro/... To get the header files installed I ran $ bjam -sTOOLS=sunpro -sBUILD=install But this command did not install the header files which would be required to use the test library. Instead a complex directory structure was created below ../sunpro/install. Is there no way to automatically get all the header files that belong to the test lib plus the other boost header files used by this lib installed automatically? Many thanks in advance for any hint. Regards, Adalbert Perbandt.

Hello all, Tried to use the forward lookahead asserts, both positive and negative and could not make a match. Is there some sample code anywhere or a tip to explain where I went wrong? Thanks, Noam

I presume you're asking because you are having problems writing code with the BGL. Rather than ask for someone to post code, why not tell us the problem you are having? Oh, by the way - the subject line really should have something to do with the body of the message. At least, that's the traditional way of doing things and it works quite well ;=) -- Jim

RE: [Boost-Users] Regex in a service..

John, Thanks for the response. How do you deal with breakpoints within a service? I'm compiling then starting the service from the service control manager. Will I still be able to debug it?

When trying to build boost_1_30_0 as follows: vcvars32.bat bjam "-sTOOLS=msvc" I get some link errors: cpp_main.obj : error LNK2001: unresolved external symbol "int __cdecl cpp_main(i nt,char * * const)" (?cpp_main@@YAHHQAPAD@Z) test_main.obj : error LNK2001: unresolved external symbol "int __cdecl test_main (int,char * * const)" (?test_main@@YAHHQAPAD@Z) unit_test_main.obj : error LNK2001: unresolved external symbol "class boost::uni t_test_framework::test_suite * __cdecl init_unit_test_suite(int,char * * const)" (?init_unit_test_suite@@YAPAVtest_suite@unit_test_framework@boost@@HQAPAD@Z) And the tool finishes telling me these not so great news: ...failed updating 12 targets... Well I'm new but after spending two days trying to work out what the heck goes on, I'm none the wiser!

On a whim, I tried changing 'boost::cmatch' to 'boost::smatch'. That fixed my problem. I'd appreciate it if someone would tell me what was going on, though. Thanks, - Mark

I seem to be having a difficult time using the Regex class in a service. It works wonderfully in a regular app. Can anyone help me out.. Basically, instantiating a regex class raises an exception. Any thoughts? Thanks Loren

Spirit for C++ style if expressions
by Vincent Finn 12 Jun '03

12 Jun '03

Hi, I am thinking of using spirit for C++ style expressions and am wondering if it is the way to go What I have will be something like ( (A != 192) AND ( (V > 0) AND (V < "89") ) ) What I need is to be able to parse this replace the AND, > etc... with operations, replace string numbers with real numbers and then apply the operation to a large number of A and V. I would have thought this would be quite a common usage but I haven't seem any samples doing it of partictuar importance is the delayed evaluation Anyone have an example of this? Vin
