I see. I'll run again when you found the error.
Should be fixed now--at least it works for me.
Ok, I updated the trunk and rebuild bjam. So when I run: python zlib.py msvc I get this: failure {{{ "['c:\\boost\\tools\\build\\v2\\test\\..\\engine\\bin.ntx86\\bjam', '-sBOOST_BUILD_PATH="c:\\boost\\tools\\build\\v2\\test/.."', '-d0', '--quiet', 'toolset=mock', '--ignore-site-config', '--user-config=', '--test-config="c:\\boost\\tools\\build\\v2\\test\\test-config.jam"', '--ignore-toolset-requirements']" returned 1 }}} reason {{{ unexpected status returned by bjam }}} changes caused by the last build command {{{ Added files : ['bin/config.log', 'bin/project-cache.jam', 'bin/standalone/ac/main.cpp', 'bin/standalone/ac/zlib.h.cpp'] Removed files : [] Modified files: [] Touched files : [] }}} STDOUT {{{ Performing configuration checks - zlib : no - zlib : no ...skipped <pbin\mock\debug>test.exe for lack of <pbin\mock\debug>test.obj... ...skipped <pbin\mock\debug\link-static>test.exe for lack of <pbin\mock\debug\link-static>test.obj... ...failed updating 2 targets... }}} STDERR {{{ }}} stacktrace {{{ at line 590 of c:\boost\tools\build\v2\test\BoostBuild.py (fail_test) from line 485 of c:\boost\tools\build\v2\test\BoostBuild.py (run_build_system) from line 61 of zlib.py (<module>) }}} I cannot find the test-config.jam in my boost folder but there is test-config-example.jam.
