Hi Volodya !

An'n Mittwoch 01 Oktober 2008 hest Du schreven:

> I know what's going on here, but first -- what is you exact command line?

hunold_at_lin-hunold ~/packages/boost/libs/thread/example $ bjam 
toolset=gcc-4.3.2-mingw  target-os=windows threading=multi 
threadapi=win32 --with-thread

This doesn't work .

bjam toolset=gcc-4.3.2  target-os=windows threading=multi 
threadapi=win32 --with-thread

works ;-))

 which  i386-mingw32-g++
/usr/local/bin/i386-mingw32-g++

i386-mingw32-g++ -v
Using built-in specs.
Target: i386-mingw32
Configured 
with: ../gcc-4.3.2/configure --target=i386-mingw32 --prefix=/usr/local --with-local-prefix=/usr/local/i386-mingw32 --enable-libgomp --enable-threads --with-arch=i686 --with-tune=generic --disable-werror --disable-nls --enable-languages=c,c++,fortran,objc,obj-c++,java --disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libstdcxx-debug --enable-cxx-flags='-fno-function-sections -fno-data-sections' --enable-version-specific-runtime-libs --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enable-hash-synchronization
Thread model: win32
gcc version 4.3.2 (GCC)

And while we're at it:

There seems to be a bug in the code which registers the "mingw"-part of the 
toolset name.
As soon as I add one mingw compiler, _all_ other gcc variant get changed 
to "gcc-mingw-XXX" where XXX is the correct version.

That means:

 bjam toolset=gcc-4.3

will result in

libs/thread/example/gcc-mingw-4.3/debug/xtime

Please note that --debug-configuration shows the correct values for the 
toolset, e.g 

notice: will use '/usr/bin/g++-4.1' for gcc, condition <toolset>gcc-4.1.3

but this will produced path elements like gcc-mingw-4.1.3

Yours,

Jürgen
