I'm pretty sure the CF I gave the link to doesn't support that but will need separate triggering. But maybe that could be changed as it was never tested (nor intended) to be used with distcc. cheers, Ingo _______________________________________________ Do not post admin requests to the list.

The option set that that's in is actially AIO, which is a subset of RT, and we don't se _POSIX_ASYNCHRONOUS_IO in <unistd.h> because we don't support one of the option flags to aio_fsync() in a POSIX compliant way. So this seems like a case where relying on the version test macros in unistd.h as a method of determining the usability of a function rather than a link test is incorrect. Just glancing through the list for the first time, I see _POSIX_SPAWN is defined as -1 but I thought posix_spawn() was supported. The following works for me, at least. It seems like the only sure way to check if something will work is to write test code trying it since one cannot rely on the version test macros nor on link tests. In retrospect, this is obvious. int main( int argc, char *argv[] ) { if( argc < 2 ) return 1; pid_t pid; int status; int ret = posix_spawnp( &pid, argv[1], NULL, NULL, argv+1, environ ); if( ret != 0 ) { errno = ret; // lazy perror( "posix_spawn" ); return 1; } ret = waitpid( pid, &status, 0 ); if( ret == -1 ) { perror( "waitpid" ); return 2; } if( WIFEXITED(status) ) printf( "Exited normally with status %d\n", WEXITSTATUS(status) ); else if( WIFSIGNALED(status) ) printf( "Terminated due to signal %d\n", WTERMSIG(status) ); else puts( "Something else" ); return 0; } smime.p7s

I would suggest you just use the ICU libraries if you want ICU formatting. I imagined the OP's situation was that he had thousands of printf- format strings, and wanted to know if he could automate the task of porting them to ICU. -- Fritz Anderson -- Xcode 3 Unleashed: Now in its second printing -- <http://x3u.manoverboard.org/ > This email sent to site_archiver(a)lists.apple.com

Especially in that case rather build a cross-compiler. Lin 2 win cross compilers are more common and guides found more readily in the web.

And it debuted in Tiger, which from my point of view makes it an antique. This email sent to site_archiver(a)lists.apple.com
