<br>sorry....quick send...try again:<br>Hi Eliot. I am trying to compie CogVM from XCode. If I choose "Mac OS X 10.5 (Base SDK)" CogVM compiles without problem.<br><br>But if I choose "Mac OS X 10.6" I have a compile error in ucontext.h line 42:<br>
<br>#error ucontext routines are deprecated, and require _XOPEN_SOURCE to be define<br><br>It comes from sqUnixVMProfile.x where you have:<br><br>#include <ucontext.h> <br>
<br><br>any ideas how can I fix this?<br></blockquote><div><br></div><div>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.</div>
<div><br></div><div>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.</div><div><br></div><div>HTH</div><div>Eliot</div><div><br></div>
