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
thx, 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../..
