Cannot compile the debug version.
by john chen 25 Aug '08

25 Aug '08

Dear All, I wouldn't be able to compile the debug version of boost_1.360 (cannot find *-gd* under boost/lib). I tried following bjam arguments: bjam ^ --prefix=c:\boost install ^ --build-dir=c:\boost ^ --sBUILD=debug ^ --toolset=msvc ^ --threading=multi ^ --link=static and bjam ^ --prefix=c:\boost install ^ --build-dir=c:\boost ^ --sBUILD=debug release ^ --toolset=msvc ^ and it still doesn't build the debug version. My environment: ms vista 32 ms vc9 sp1 boost 1.360 bjam 03.1.17 Can someone tell me how to get the debug version? Thanks very much. John

[math][libs] Header-only status wrong for Boost.Math
by Daryle Walker 25 Aug '08

25 Aug '08

Looking at <http://www.boost.org/doc/libs>, I see 14 entries using separate source, but I have 15 source directories still in my all- Boost library project. It seems that the Special Function section of the Math library has separate source for the (optional) C99 and TR1 math functions, but the library page doesn't list that. (The source files are mentioned in the Math-SpecFunc docs.) Can that be changed, please? -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com

[test] More on formatting log entries for XCode (by default when applicable)
by Daryle Walker 25 Aug '08

25 Aug '08

This is based on the <https://svn.boost.org/trac/boost/ticket/2059> ticket I entered a couple months ago. I just tried out the actual change needed and attached it to the ticket. (I just made a project that compiles all the mandatory Boost source code, like the unit-test framework, into various static libraries I can include in my other projects without repeating the compilation instructions [or wasting disk space]. Centralization is fun.) I still don't know if my __APPLE_CC__ preprocessor test is the official way to check for Xcode, or any compatible, setup. I heard that the current code is supposedly formatted for Visual C++'s error message handling. If so, and the class I changed is _not_ where the per-compiler-product changes are supposed to go, then move the code as needed. (I guess there would be parallel visual-c++ and xcode default formatting classes.) -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com

Is this done like MSVC stdafx files? Thanks, Robert ________________________________

[Release] Supported platforms are...?
by Gennaro Prota 24 Aug '08

In <http://www.boost.org/development/tests/release/developer/summary.html> I just see seven platform/compiler combinations. Are these the only ones officially supported for release(s)? -- Genny

Lag of trunk tests?
by Gennaro Prota 24 Aug '08

24 Aug '08

I'm watching the trunk regression summary for several days and almost all the tests are reportedly stale at 19-21 August. If I go, for instance, to <http://www.boost.org/development/tests/trunk/Sandia-sun.html> it says that tests are run *nightly* (incidentally, it also doesn't tell anything about the gcc invocation). What's wrong? -- Genny

[FileSystem.path] has_branch_path() not found
by Ming 24 Aug '08

24 Aug '08

Hi all, I try to use boost 1.36 instead of 1.33 to compile libtorrent library. But I got a error of "error C2039: 'has_branch_path' : is not a member of 'boost::filesystem::basic_path<String,Traits>' " I cannot find the function in boost\filesystem\path.hpp in version 1.36, but can find in in 1.33. Does has_branch_path() is deprecated in the new version library? Or it is moved to other classes? Yours, CMing

[C++-sig][BGL] python bindings for intel compiler
by Sandeep Gupta 24 Aug '08

24 Aug '08

Hi, I haven't been able to create correct python bindings for BGL for intel compiler. Will greatly appreciate any help as it has been more than four months since I first encountered the problem. The python bindings in the tutorial and examples work fine. The bgl_python code from the sandbox compiles smoothly. I believe I have set the PYTHONPATH and LD_LIBRARY_PATH correctly. But the import of boost.graph fails with following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "...../bgl-python/lib/python/boost/graph/__init__.py", line 16, in <module> from boost.graph._graph import * ImportError: "...../bgl-python/lib/python/boost/graph/_graph.so: undefined symbol: _ZN5boost5graph6python11basic_graphINS_11undirectedSEED1Ev" Thanks, Sandeep

Trying to make an all-Boost header/library
by Daryle Walker 24 Aug '08

24 Aug '08

I started out making a group Boost project for Xcode, so I can compile Boost.Test and S11N just once and include them in my other projects. Then I wondered how far can I take this. 1. I tried including all the sources in the libs/ directory. 2. It seems that there is source code in the detail, function-types, and smart_ptr that we don't really need, so I've now excluded it. (The function-types one needed the Wave _tool_ to be created, so I really hope it's not needed.) 3. Just like Linux has various package installers (apt-get, etc.), so does Mac OS X. I originally had Fink, but switched to MacPorts. Dowloaded packages include: bzip2, docbook, doxygen, expat, fop, ghostscript, graphviz, icu, libxml1, openmpi, subversion, texlive, and zlib. 4. I generally have one static library file for each Boost library. For libraries that need another, I made the corresponding targets dependencies, but I didn't link the results together. 5. The test library gets three static libraries. They all include a "main" or something like it, so I'll probably make a custom fourth library for a grand Boost library file. 6. The graph library has extra support for Expat, which I included from MacPorts. Should I leave that out for a publicly distributed grand Boost library file, since I can't guarantee a general user having it? 7. The iostreams library has extra support for bzip2 and zlib, which I originally included from MacPorts. I realized that my system (Mac OS X 10.4, PowerPC) includes copies of those libraries and headers, so I switched to those. This means that I can safely include them in a grand Boost library, right? 8. I left out the long-double versions of the math functions because they're disabled on my system. Should I try (conditionally?) including them on Intel-builds since I think they're supported there? How do I do that? 9. I have the MPI library built because I have OpenMPI through MacPorts. Should I leave that out of a grand Boost library? 10. For the Python library, I tried connecting to the OS's Python.framework. 11. Because of [9] and [10], I made the MPI-Python library too. I guess its status for a grand Boost library depends on the answer for [9]. 12. Does anyone have any idea how to create a Python extension? I did a very quick read of the docs and couldn't get it. So I just made a shared library for the MPI extension for Python and included the applicable static libraries and framework. (It seems you are supposed to use a special Python script, and _never_ manually.) Since I made a final product, I had to link in my static libraries for MPI, Python, MPI-Python, and S11N, then link the OpenMPI libraries from MacPorts, then the system's Python framework, then a surprise need for some Open libraries also from MacPorts. 13. For the regex library, I defined having ICU, and included it from MacPorts. Should I leave out ICU support in a grand Boost library? Actually, I think the system has buried copies of Expat and ICU, but I don't know how to reach them, or if it's even possible. Maybe I should try making a framework of all of Boost, modulo the answers on what I should include above. Should I somehow include object-code for the parts of the Test library that bring a "main"? Or do I have to tell the user to get the framework, then download regular Boost to build what's needed for Testing (or MPI, MPI/Python, Graph/Expat, or Regex/ICU)? I think I would have to make a "boost/boost.hpp" overall header to be the focal point of the framework, which may be a good idea to create anyway. How would I test it? Hmm, would anyone here like to take a challenge to create a program that uses ALL of Boost, so every symbol gets exercised? -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com

[smart_ptr] Is smart_ptr header only?
by Daryle Walker 24 Aug '08

24 Aug '08

When trying to make an all-Boost huge library, I found some src/*.cpp files in smart_ptr's libs directory. Are these official, or can I leave them out? -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
