[Boost-users] [boost-users] Build boost libraries (e.g. filesystem) with gcc and -m32

Hi all,

I'm working on Intel Core2 Duo machine running Linux and have the
following problem:

I want to compile 32-bit versions of the boost libs with gcc, so that
I can link and create 32bit programs.
Unfortunately if I use
bjam --toolset=gcc stage

the libraries are built as 64bit libraries so if I link I get the
following error:
>g++ filesystem_test.cpp -g -m32 -c -o filesystem_test.o -L../boost/boost_1_35_0/stage/lib -I../boost/boost_1_35_0
>g++ filesystem_test.o -L../boost/boost_1_35_0/stage/lib -m32 -o filesystem_test -lboost_filesystem-gcc41-mt
/usr/bin/ld: skipping incompatible
.../boost/boost_1_35_0/stage/lib/libboost_filesystem-gcc41-mt.so when
searching for -lboost_filesystem-gcc41-mt

If I omit -m32 everything works fine.
Help is very much appreciated,
Andreas
