You must add at least the cygwin/bin directory to your windows 
path. Try to start the program from inside cygwin (the  shell).

help on running c program on cygwin

[Lily Tsai]

I just installed Cygwin on XP and tried running a simple helloworld in c.
After a good compilation using gcc, I get nothing when trying to run the
outputfile.

$gcc helloworld.c -o helloworld.exe

$helloworld.exe


nothing.

When I double-click on the helloworld.exe icon on Windows Explorer, I get
an error prompt:

"This application has failed to start because cygwin1.dll was not found.
Re-installing the application may fix this problem."


So, I re-installed and nothing changed.

Can you help?

Thanks in advance,
Lily

help on running c program on cygwin

[David Starks-Browning]

Lily,

I hate to be the third to reply but I didn't find the first two
responses satisfactory.

That depends what you mean by "nothing".  If bash says "command not
found", then read the FAQ entry:

	Bash says "command not found", but it's right there!

If *truly* nothing happens, then I have no explanation.

That's because Windows does not have C:\cygwin\bin (or wherever you
installed Cygwin) in its PATH environment variable.

Someone with Windows XP will have to tell you how to remedy this.  On
NT the "System" control panel lets you set environment variables.  On
9x you can add something to autoexec.bat.

Cygwin will set the PATH for you when you invoke the Bash shell from
the "Cygwin" shortcut.  But that doesn't help when you double-click an
executable from Windows Explorer.

Hope this helps.

David

If, after you think twice about it, you still wish this to work, make a
Windows shortcut to cygwin1.dll in the folder with your helloworld.  Ugly.
