I have a linux machine on x86-64 that I'm trying to use to build Boost in 32-bit. I can build other source in 32-bit, so I figure my environment is set up correctly unless Boost needs something I'm not thinking of. I executed bjam as: bjam --toolset=gcc address-model=32 --with-signals stage Everything builds fine, but the libs aren't 32-bit, file says: libboost_signals-gcc34.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), stripped Any ideas? -- Nick
