Hi, Frankly I do not know who supports Boost.Build, but how long it'll stay broken? I can't say when it started, but ever since I started working on Boost.Test changes I experience constant problems. I can't believe I am the only one. 1. When you take boost trunk and go into Boost.Test build or test directory and try building using any toolset it immediately fails with: ..\..\..\libs\test\build\Jamfile.v2:110: in modules.load rule boost-install unknown in module Jamfile</.../trunk/libs/test/build>. .../trunk/tools/build/v2/build\project.jam:314: in load-jamfile .../trunk/tools/build/v2/build\project.jam:62: in project.load .../trunk/tools/build/v2/build\project.jam:766: in project.use .../trunk/tools/build/v2/build\project.jam:89: in load-used-projects .../trunk/tools/build/v2/build\project.jam:73: in load .../trunk/tools/build/v2/build\project.jam:115: in load-parent .../trunk/tools/build/v2/build\project.jam:464: in initialize .../trunk/tools/build/v2/build\project.jam:309: in load-jamfile .../trunk/tools/build/v2/build\project.jam:62: in load .../trunk/tools/build/v2/build\project.jam:115: in load-parent .../trunk/tools/build/v2/build\project.jam:464: in initialize .../trunk/tools/build/v2/build\project.jam:309: in load-jamfile .../trunk/tools/build/v2/build\project.jam:62: in load .../trunk/tools/build/v2/build\project.jam:168: in project.find .../trunk/tools/build/v2\build-system.jam:570: in load .../trunk\tools\build\v2/kernel\modules.jam:283: in import .../trunk\tools\build\v2\kernel\bootstrap.jam:142: in boost-build .../trunk\boost-build.jam:17: in module scope 2. Once I remove boost-install from Boost.Test Jamfile, I get bun of errors like this: ..\..\..\libs\test\src\compiler_log_formatter.cpp(16) : fatal error C1083: Cannot open include file: 'boost/test/impl/compiler_log_formatter.ipp': No such file or directory Essentially boost home directory is missing from include path. How come? 3. Once I add "<include>../../.." into requirements section I can build with msvc toolsets. Now I am trying to use gcc toolset on Windows. I have latest cygwin installation and I am getting these errors (lots of them): gcc.compile.c++ ..\..\..\libs\test\build\bin\gcc\debug\link-static\compiler_log_formatter.o "g++" ... # compilation line here Access is denied. Apparently g++ is not an executable anymore with cygwin. I am able to workaround this by adding using gcc : 4.5.3 : g++-4.exe ; into user-config.jam, but why Boost.Build can't figure this out and do I need to support this file now myself? 4. After the fix I am able to build dll based tests, but when I attempt to use static library version of Boost.Test I am getting: gcc.archive ..\..\..\libs\test\build\bin\gcc-4.5.3\ debug\link-static\libboost_unit_test_framework.a "/usr/i686-pc-cygwin/bin/ar.exe" rc .... # list of object files here "/usr/i686-pc-cygwin/bin/ranlib.exe" ... # lib here The system cannot find the path specified. The system cannot find the path specified. This one I do not know how to fix. So the situation is that I cannot test any static library based unit tests (as a side note, this inability was the cause of crashes which interrupted trunk testing month ago). I addition whenever I want to check in my local changes to Jamfile (excluding hacks which I actually do not want to check in) it is rather annoying process. Any help would be appreciated, Gennadiy
