multi_array dinamically built
by Ramón Casero Cañas 10 Jan '03

10 Jan '03

Hi, I would like to dinamically create a multi_array. Something like typedef boost::multi_array<bool, 2> BoolMatrix; typedef boost::multi_array<bool, 2>::index indexBoolMatrix; boost::array<BoolMatrix::index, 2> shape = {{ 5, 8 }}; BoolMatrix *A; // NO MEMORY ALLOCATED ... A = new BoolMatrix(shape); // MEMORY ALLOCATED A.assign(data,data+40); // ELEMENTS INITIALIZED The compiler (gcc 2.95.4) says that this kind of things are wrong. Or didn't I understand how the memory allocation in multi_array works? Cheers, Ramón.

NEWBIE - building on linux
by gcs_99 <gregsteele＠woodsidenet.com> 10 Jan '03

Can anyone point me to directions for building boost under linux. I have installed bjam. When I type bjam -sTOOLS=gcc in my boost root dir I get tons of errors. I understand that much of boost is implemented as templates in header files. Is there an install script to place these in the correct location for gcc? Thanks. G

Installing boost regex
by Alisdair Meredith 10 Jan '03

10 Jan '03

We're (still!) in the process up upgrading our software to the latest borland compiler, BCB6 I am now at the stage of trying to get the boost libraries integrated into our builds. After running bjam I get some libboost_regex libs, but these don't seem to be used. Reading the separate install procedure under the regex library, I find another install procedure that produces a set of libraries targetted at BCB that do solve my problems. Is this the correct procedure? Is there any way to integrate this with the jam scripts in the future? If not, should we add a link under installing boost to the separate procedure for the regex libraries? -- AlisdairM Team Thai Kingdom

stop a thread

How to stop(or cancel) a thread? Suppose I have a main thread and a worker thread, the worker thread does something looply,and when the main thread get a message indicating the process should exit, I want stop the worker thread,how to do that?I have read other thread library,their thread class supply a method called stop or cancel which stops the thread. Their Implementation is:the thread class has a data member indicating whether the thread should stop,and the thread function looply check the data member whether the thread should stop.Generally the data member's type is a bool or Event. Is it the best way to stop the thread? How the boost to deal with this? Thanks in advance.

Starting to use unit tests
by Scott Nesbitt 10 Jan '03

10 Jan '03

I am in to process of adding the boost test framework to our project, and am looking for advice or samples for how best to do this. Specifically, we have multiple executables sharing several libraries. I was thinking about having a different test suite for each library, but don't see much documentation on using multiple test suites. Any advice or pointers?

bind() and argument_type?
by Duane Murphy 09 Jan '03

09 Jan '03

I am trying to use bind() with std::not1() (I think this is what I want to do :-). But std::not1() gets a compiler error because bind doesnt have an argument_type typedef. bool is_something( int x, int y ) { return something( x, y ); } { ... if ( std::not1( boost::bind( is_something, 3, _1 ) ) ) { // not something } } Am I approaching this incorrectly? Does bind support argument_type? Thanks for the advice, ...Duane

RE: [Boost-Users] Problem with BOOST_STATIC_ASSERT

Thanks for investigating this, John. I don't have access to the beta VC7.1 compiler. Do you (or does anyone else) know if this will still be a problem with the forthcoming version of the Microsoft compiler?

Constructing > a similar program using "is_POD" behaves as expected: I can reproduce that with both VC6 and VC7, all the other compilers I have access to are OK with it. It's clearly a compiler bug, because the assert is triggered even though no instance of the template class is ever created.
