[Python] Debug Python (PY_DEBUG) libs and auto-linking
by Brian O'Kennedy 18 Apr '08

18 Apr '08

Hi, Apologies for the long email, but I figured I might as well be detailed in my explanation. My two questions are below regarding the process of building Boost.Python against a PY_DEBUG debug build of Python, and the failure of auto-linking of such debug libs of Boost.Python (those with 'gyd' in the name). I'm using both the Release and Debug versions of Python 2.5.1 on Windows compiled with Visual Studio 2005. The Debug version of python produces python_d.exe and python25_d.dll, while the release version uses python.exe and python25.dll. I've downloaded and built Boost 1.35.0 with the following steps: 1. Edit Jamroot as follows: (lines I add start with a "+" ) <define>BOOST_ALL_NO_LIB=1 + <define>_SECURE_SCL=0 # Used to encode variant in target name. See the I do this since our codebase is compiled without the secure iterators for performance reasons. This isn't relevant to my question, but I might as well mention it. Also, I add the following to build the debug python libs: # location of python local python-root = [ MATCH "^--with-python-root=(.*)" : [ modules.peek : ARGV ] ] ; PYTHON_ROOT ?= $(python-root) ; + using python : 2.5 : C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PCbuild\\python.exe + : C:\\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\Include C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PC + : C:\\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PCbuild + : <python-debugging>off ; + using python : 2.5 : C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PCbuild\\python_d.exe + : C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\Include C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PC + : C:\\3rdparty\\Python\\Python-2.5.1-vc8sp1-Patch1\\PCbuild + : <python-debugging>on ; # Select the libraries to install. libraries = [ libraries-to-install $(all-libraries) ] ; I could also add this to my user-config.jam file but I got annoyed by bjam not picking that up if it is in the same folder as Jamroot, it would only find it if I put it in my user home. Then I trigger the builds using bjam: bjam.exe -d +2 --toolset=msvc --build-type=complete install bjam.exe -d +2 --toolset=msvc --with-python python-debugging=on install debug bjam.exe -d +2 --toolset=msvc --with-python python-debugging=off install release This gives me the complete Boost I want with the addition of the Release and Debug versions of Boost Python. The Debug version of Boost Python I'm after is boost_python-vc80-mt-gyd-1_35.dll and the release is boost_python-vc80-mt-1_35.dll So, my first question is: Surely there must be an easier way to do what I tried to achieve above? Should building a true debug (ie, a traditional python debug lib with PY_DEBUG enabled) version of Boost Python really take this much hackery? This is where people point out to me just how little I know about bjam / boost build... Second problem is the auto linking of.Boost Python. If I create an DLL application in Visual Studio 2005, set the include directories, set the library directories, set the output target as BoostPythonTest.pyd in Release, and BoostPythonTest_d.pyd in Debug, I get the following situation. BoostPythonTest.cpp #include <boost/python.hpp> char const* greet() { return "hello, world"; } BOOST_PYTHON_MODULE(BoostPythonTest) { using namespace boost::python; def("greet", greet); } This auto-links boost_python-vc80-mt-1_35.dll in Release mode just as it should and everything works just fine. In Debug mode, this auto links boost_python-vc80-gd-1_35.dll which is the Boost.Python debug lib which does not define PY_DEBUG which is not the behaviour I want. The Boost Python docs makes some reference to using BOOST_DEBUG_PYTHON to change the behavior of wrap_python.hpp but no such support seems to exist to modify the auto-linking behavior. To get my module to link to release python in release mode, and debug python via boost_python-vc80-mt-gyd-1_35.lib (with PY_DEBUG, ie python25_d.dll) in debug mode, I need to do the following: BoostPythonTest.cpp #define BOOST_PYTHON_NO_LIB #ifdef _DEBUG #define BOOST_DEBUG_PYTHON #pragma comment(lib, "boost_python-vc80-mt-gyd-1_35.lib" ) #else #pragma comment(lib, "boost_python-vc80-mt-1_35.lib" ) #endif #include <boost/python.hpp> char const* greet() { return "hello, world"; } BOOST_PYTHON_MODULE(BoostPythonTest) { using namespace boost::python; def("greet", greet); } I've had a look through the auto-linking code in boost and no special case seems to exist for the debug Python libraries. Once again, my question is whether this really is what I need to do to get Boost Python to play nicely with PY_DEBUG debug mode Python? Thanks for any advice, or general abuse for my misunderstanding on how to configure boost build properly. Brian Ps: If you do not do this and link to boost_python-vc80-gd-1_35.lib instead you get this warning when you try to import your lib into a debug python interpreter: >>> import BoostPythonTest Fatal Python error: Interpreter not initialized (version mismatch?) ________________________________________________________________________ This e-mail, and any attachment, is confidential.

[filesystem] problems cross-compiling for QNX from windows host
by Guenther Stattenberger 18 Apr '08

18 Apr '08

Hi, I have some strange errors when cross-compiling some of the boost libraries for QNX on a windows host: According to the Jamfile, the filesystem library includes boost system in the linking stage NOT as a library (via e.g. -lboost_system-mt-d) but as a (shared) object. This has the effect, that somehow the current path of the libboost_system-mt-d.so file (e.g. bin.v2\libs\system\build\qcc\ debug\target-os-qnx\threadapi-pthread\threading-multi) is inserted into the filesystem library. Naturally, after moving the libraries to the QNX target this path isn't valid any longer. The runtime the complains "Could not find library ...". If I rename libboost_system-mt-d.so to have the path mentioned above prepended (not as a path, but really the filename, containing the backslashes) everything works fine. As a first workaround I decided to remove boost_system from the linking of boost_filesystem in the Jamfile and specify -lboost_system-mt-d in the link of my executable. This works fine, but unfortunately only up to the first exception. The program now gets aborted during unwind of the exception. The question now is: could somebody please indicate, why the boost_system library is not linked via the -l switch, and what is wrong trying to do this. Another solution might be to convince the linker not to include the compile-time path of the .so file but I was not successful trying this. Any help would be greatly appreciated. Thanks, Guenther

[lambda] Lambda for member access
by Robert Dailey 18 Apr '08

18 Apr '08

Hi, In the Boost.Lambda documentation, it has a section for operators that cannot be overloaded, but I'm not really sure if this means you cannot use these operators with lambda expressions. I have the following map: class SomeClass { public: void Foo() {} }; std::map<int, SomeClass> mymap; I want to be able to do std::for_each() on this map and use lambdas to call the Foo() member on each element in the map. For example: std::for_each( mymap.begin(), mymap.end(), _1.second.Foo() ); Obviously the above does not compile. Is there a way to make this work without doing some crazy template specialization? Thanks.

[Boost.Iostreams] Building iostreams with zlib support
by Andreas Profous 17 Apr '08

17 Apr '08

Hi, I'm trying to compile the following example code on Windows XP using MS Visual Studio 2005: -- from http://www.boost.org/libs/iostreams/doc/classes/zlib.html#installation ////////////////////////////// #include <fstream> #include <iostream> #include <boost/iostreams/filtering_streambuf.hpp> #include <boost/iostreams/copy.hpp> #include <boost/iostreams/filter/zlib.hpp> int main() { using namespace std; using namespace boost::iostreams; // added this line ifstream file("hello.z", ios_base::in | ios_base::binary); filtering_streambuf<input> in; in.push(zlib_decompressor()); in.push(file); boost::iostreams::copy(in, cout); } //////////////////////////////// So I downloaded the zlib library into the directory C:\Libs\zlib123 plus a prebuilt windows binary into the directory C:\Libs\zlib123\dll32 After reading http://www.boost.org/libs/iostreams/doc/installation.html I tried to add zlib.cpp to my test project, and to add the line #define BOOST_IOSTREAMS_NO_LIB to my source file. I got a bunch of linker errors, e.g. 1>zlib.obj : error LNK2019: unresolved external symbol _crc32 referenced in function "protected: void __thiscall boost::iostreams::detail::zlib_base::after(char const * &,char * &,bool)" (?after@zlib_base@detail@iostreams@boost@@IAEXAAPBDAAPAD_N@Z) 1>C:\Dev\Test\Test\Debug\Test.exe : fatal error LNK1120: 9 unresolved externals. If I delete ' #define BOOST_IOSTREAMS_NO_LIB' I get the following error: 1>LINK : fatal error LNK1104: cannot open file 'libboost_zlib-vc80-mt-gd-1_34_1.lib' Which is a file that doesn't exist. As I understand it I have to rebuild boost.iostreams with zlib support: C:\boost\boost_1_34_1\libs\iostreams\build>bjam "-sNO_COMPRESSION=0" "-sNO_ZLIB=0" "-sZLIB_SOURCE=C:\Libs\zlib123" "-sZLIB_LIBPATH=C:\Libs\zlib123\dll32" "-sZLIB_BINARY=zlibwapi.dll" I tried this and that but to be honest I don't really know what I'm doing and it didn't work. I would like to compile a static library and link my program against it, so that the example code works. It would also be ok to link it against a .dll - I don't really care, I just want to SOMEHOW use it! :) Can somebody give me detailed instructions on how to do that? Andreas

[...] Hi Daniel, I don't see any blatant mistake, but as your code is not complete and I therefore cannot compile it and run it I'm missing the problem. A shot in the dark: How's your STRING type hashed according to Boost.Hash? Remember that to use a user-defined type with Boost.Hash you have to define an appropriate hash_value overload as described at http://boost.org/doc/libs/1_35_0/doc/html/hash/custom.html If after examining this point your problem persists and you can provide a compilable snippet for me to run I can try to be a little more helpful.

[thread] Condition::notify_one, wait
by Anteru 17 Apr '08

17 Apr '08

Hiho, I'm using the new Boost Threads for a Thread Pool, however, I've got some weird problems. The documentation of Condition::notify_one says it unblocks one of the threads waiting currently on the condition -- what happens if I have several threads waiting and I call notify_one twice? It seems that on Windows/x64/VC9, only on thread wakes up if notify_one is called twice in a row. Is this right? Second, wait says: "The thread will unblock when notified by a call to this->notify_one() or this->notify_all(), or spuriously". Is it likely that a condition unblocks spuriously? After all, I'd expect to unblock only after calling notify_* and not "by accident". Is there any way to get diagnostic output when a wait has been called spuriously? The problem I'm having at the moment is: I have PIMPLed Boost.Thread behind some simple wrappers, and I'm using them like this here: Lock lock (mutex_); if (queue.empty ()) { waitForItem.wait (lock); } with Lock being a wrapper for scoped_lock, mutex being a wrapper for mutex and waitForItem being a condition, and funnily enough it goes waiting even though there is an item in queue (i.e., queue.empty () == false). I'm not sure where this is coming from (all access to queue is protected using mutexes), only candidate at the moment is that when inserting, I call notify_one, and if two items get inserted one right after the other, I assume that only one thread is woken up and hence the other remains waiting although there is an item in the queue. It works when I use notify_all (), but this does not smell right to me :/ Thanks, Anteru

Re: [Boost-users] BGL problem

Hi Giuseppe, I have looked at your code, and it appears that you are not adding a graph_name property map to the dynamic_properties object. Not all graphs have a graph_name property, so it is necessary to use the property map interface to retrieve the graph name. Take a look at libs/graph/test/graphviz_test.cpp, specifically the lines: boost::ref_property_map<graph_t*,std::string> gname( get_property(graph,graph_name)); dp.property("name",gname); Hope this helps, ron On Mar 25, 2008, at 10:22 AM, Giuseppe Di Guglielmo wrote: > Dear Ronald, > I'm using Boost Graph Library. > > I saw this ticket > http://svn.boost.org/trac/boost/ticket/731 > GraphViz reader ignores graph properties. > > I am trying to read the graph name from a graph I loaded from a DOT > file, > but the property seems to be empty.

[1.35, Boost.Test] error when using system in a test

The following (see below) test programm compiles under both 1.34.1 and 1.35.0; if linked against 1.35.0 it produces the following error message: Running 1 test case... A unknown location(0): fatal error in "test_call_system": child has exited; pid: 1000; uid: 16129; exit value: 0 *** 1 failure detected in test suite "Master Test Suite" With 1.34.1, no errors are found: Running 1 test case...
