Attached is a nice small program which does system("cmd /?"); The call works pretty well when I run it from Cygwin environment. In my situation I need to run standalone Cygwin programs (i.e. simply from Windows cmd.exe). In this case the program fails - system() does not seem to find cmd.exe and returns -1 (yes, cygwin1.dll is on PATH). If I change system() to good old CreateProcess() everything runs fine. My questions: 1) what is the reason for this behavior? 2) can I somehow alter the argument to system() to make it working? Or perhaps modify PATH or any other environment variable before running Cygwin program? Thanks in advance, Yuri --0016e6d2616cfb5b3804b69d8b80 Content-Type: text/plain; charset=US-ASCII; name="gcc.txt" Content-Disposition: attachment; filename="gcc.txt" Content-Transfer-Encoding: base64 X-Attachment-Id: f_gxgzl9jm0 I2luY2x1ZGUgPHN0ZGxpYi5oPg0KI2luY2x1ZGUgPHN0ZGlvLmg+DQoNCmlu dCBtYWluKCkgew0KCWNoYXIgdG1wWzI1Nl07DQoJZ2V0Y3dkKHRtcCwgc2l6 ZW9mKHRtcCkpOw0KCXByaW50ZigiQ3dkOiAlc1xuIiwgdG1wKTsNCg0KCWlm KCAwICE9IHN5c3RlbSgiY21kIC8/IikgKSB7DQoJCXByaW50ZigiRmFpbGVk XG4iKTsNCgl9DQoNCglyZXR1cm4gMDsNCn0NCg0K --0016e6d2616cfb5b3804b69d8b80 Content-Type: text/plain; charset=us-ascii -- 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 --0016e6d2616cfb5b3804b69d8b80--
