[Boost-users] Réf. : Cross-compiling boost for win32 on linux

I have a similar problem: building boost for win32 from cygwin (i.e. with -mno-cygwin flag).
What I did is to compile bjam for gcc-nocygwin toolset (fine!) and use this bjam to build boost but the flag "-mno-cygwin" is not given to g++.
I tried to add "cflags=-mno-cygwin cxxflags=-mno-cygwin linkflags=-mno-cygwin" on the bjam command line but g++ is still invoked without -mno-cygwin. The same happen with toolset gcc and gcc-nocygwin.

Here is an extract of the output of bjam -d2:

gcc.compile.c++ bin.v2\libs\wave\build\gcc-3.4.4\release\link-static\instantiate_cpp_exprgrammar.o

    "g++"  -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall  -DBOOST_ALL_NO_LIB=1 -DNDEBUG  -I"." -c -o "bin.v2\libs\wave\build\gcc-3.4.4
\release\link-static\instantiate_cpp_exprgrammar.o" "libs\wave\src\instantiate_cpp_exprgrammar.cpp"

What is the solution? How can I add the flag "-mno-cygwin" to gcc, g++ and the linker?  I have spent so much time to try to find a solution that I thinking of giving up the idea to use the boost
library.

Hi,
I used to be able to cross-compile boost on linux for win32 with
boost.build v1 without problems, but now with v2 I cannot find the
mingw toolset. It seems that now we can use gcc toolset but with a
mingw flavor. So, where can I set this flavor? Everything I do makes
bjam use plain g++ (for building to run on linux),
not mingw32-g++ (run on win32).

Regards,
Rodolfo Lima.
