I am trying to build Boost for G++ 32-bit applications on an Opteron system running Linux Fedora Core 3. This is my command:
bjam --user-config=user-config.LINUX_AMD32 threading=multi instruction-set=opteron address-model=32 variant=release,debug,profile --stagedir=stageA32 stage
...
It recognized the other options I requested, but not 'address-model=32'.
No reply? I realize that I can add '-m32' to the flags in my user-config file, but I was hoping that someone will fix the build system.
I presume you have already checked SVN HEAD, or 1.35, and the problem is still here? For the record, SVN HEAD version of tools/build/v2/tools/gcc.jam has this: flags gcc OPTIONS <architecture>x86/<address-model>32 : -m32 ; flags gcc OPTIONS <architecture>x86/<address-model>64 : -m64 ; I suspect you version might not have the first line, so if the compiler default is 64-bit, you'd always get 64-bit binary; you might want to add the first line to your gcc.jam - Volodya
