Re: execv bug???



If you want a call that uses the PATH environment variable you should use execvp instead of execv

Actually, I'ts preferable to use a call that Don't use the PATH environment variable, and specify the absolute path
of the executable instead.

Have a well known program, qmail, compiled on Leopard. We've used it for 3 years or so on Mac Tiger et al.

qmail runs on most any platform out there. In the code, are the following lines:

    if (chdir(auto_qmail) == -1) _exit(61);
    execv(*binqqargs,binqqargs);
    _exit(120);


binqqargs is defined as:

static char *binqqargs[2] = { 0, 0 } ;

Later it is set as:

  binqqargs[0] = "bin/qmail-queue";


auto_qmail contains the path /var/qmail

So, the chdir on all other platforms goes to /var/qmail, and, the execv executes from there bin/qmail-queue.

The execv (added more code) returns an error 2, or, file not found on Leopard.

It works perfectly on Tiger, freeBSD, you name it.

If I change binqqargs to /var/qmail/bin/qmail-queue, all works fine.

Could it be a bug in execv on Leoprd when when not using a absolute filename? If so, what is the mechanism to report and hopefully some day get it fixed?
