sorry....quick send...try again: Hi Eliot. I am trying to compie CogVM from XCode. If I choose "Mac OS X 10.5 (Base SDK)" CogVM compiles without problem.

But if I choose "Mac OS X 10.6" I have a compile error in ucontext.h line 42:

#error ucontext routines are deprecated, and require _XOPEN_SOURCE to be define

It comes from sqUnixVMProfile.x where you have:

#include <ucontext.h>

any ideas how can I fix this?

I guess three ways. One is simply to define _XOPEN_SOURCE. But better is to figure out how to get the program counter pointer value from a signal handler in 10.6. i.e. what the profiler does is periodically sample the VM thread's program counter. It does this using a thread that sends SIGPROF to the VM thread and have the SIGPROF handler (pcbufferSIGPROFhandler) get the interrupted pc from the ucontext structure passed into the signal handler. Presumably there's a new way of doing this in 10.6. Find out what that is.

The third way is simply to define NO_VM_PROFILE and then the file will provide only stubs and you'll have no functional VM profiler.

Did you try setting the option "Mac OS X 10.6" in XCode ?

Hmm. I didn't have any trouble compiling Cog on 10.6. Which Xcode version are you using?

Nope; that's probably the difference then. I used the makevm script in the macbuild directory.

Exactly. That works perfect for me also. Even using the default XCode configuration. It only fails when I explictly choose the option "Mac OS X 10.6" in XCode
