I would like to know where there is a svn/git repo for this code. It would make it much easier to collaborate. On Feb 7, 2011, at 5:58 PM, Gregory Crosswhite wrote:

Thanks, Greg

I've uploaded boost.context 0.6.4 - unfortunately I've no Mac OS X installation and I hope someone can test the lib on the Mac platform:

ucontext_t: bjam toolset=gcc --debug-building

fcontext_t on i386: bjam toolset=gcc architecture=x86 instruction-set=i686 address-model=32 context-impl=asm --debug-building

fcontext_t on x86_64: bjam toolset=gcc architecture=x86 instruction-set=yorksfield address-model=64 context-impl=asm --debug-building

It is available in this directory http://www.boostpro.com/vault/index.php?action=deletefile&filename=boost.context-0.6.3.zip&directory=Concurrent%20Programming& regards, Oliver

I am still having problems with bjam, but from what I can tell these are the commands that should build your example by hand. Perhaps there is something I am missing about the commands I need to pass to gcc.

I get the same results with: g++ -o link example/link.cpp src/asm/fcontext_x86_64_sysv_macho_gas.S src/protected_stack_posix.cpp -I../..

gcc -c -o fctx.o src/asm/fcontext_x86_64_sysv_macho_gas.S g++ -c -o protected_stack_posix.o src/protected_stack_posix.cpp -I../.. g++ -o link example/link.cpp protected_stack_posix.o fctx.o -I../..

Undefined symbols: "_make_fcontext", referenced from: boost::contexts::context<boost::contexts::protected_stack>::context(void (*)(void*), boost::contexts::context<boost::contexts::protected_stack>&, void*, boost::rv<boost::contexts::protected_stack>&)in ccW4I8zo.o "_swap_fcontext", referenced from: boost::contexts::context<boost::contexts::protected_stack>::jump_to(boost::contexts::context<boost::contexts::protected_stack>&)in ccW4I8zo.o "_get_fcontext", referenced from: boost::contexts::context<boost::contexts::protected_stack>::context(void (*)(void*), boost::contexts::context<boost::contexts::protected_stack>&, void*, boost::rv<boost::contexts::protected_stack>&)in ccW4I8zo.o ld: symbol(s) not found collect2: ld returned 1 exit status

strange on my linux x86_64 system I get it compiled without linker errors: g++ -o link example/link.cpp src/asm/fcontext_x86_64_sysv_elf_gas.S src/protected_stack_posix.cpp -I ../../ I found in the INet following: 'Mac OS S requires yout to prefix all your libc method name with "_". Most code sample in Unix world don't have this constraint.' May this be the reason? Especially because I don't declare fcontext-t functions (make_fcontext(), swap_fcontext() etc.) with a leading underscore. Sorry - I've no experience with Mac OS X. Maybe someone can help? Oliver
