It works perfectly on my 32-bit install (where, as it happens, the fork() issue never shows up either). However, on my 64-bit install, the spawnv() call is returning with an error -- 'No such file or directory' -- when I try to spawn /bin/sh. I have attached the output from 'strace' on this process. If you look at line 602, I think you can see where the exception gets generated. Can you see what is going on? I tried to create a simple test program that shows the problem, but (so far) they all work. Thanks.
Interesting. No, off hand, the strace output doesn't shed any light on the situation for me either. Clearly an access violation occurs when /bin/sh is spawned but if it only happens in your specific code and not in a simple invocation of spawn(), that suggests a possible usage problem. I know, that's not much help. ;-) -- Larry _____________________________________________________________________ A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting annoying in email? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
