im trying to run a c program on my windows 7 computer using eclipse and im running into a little snag. I currently have Eclipse downloaded on my computer with the CDT plugin
For me (on OS X), even though my personal environment (i.e. if in bash, echo $PATH) had /Developer/usr/bin in it, I still had to add it to Eclipse's Environment variables:
Go to Eclipse Preferences -> C/C++ -> Environment -> Add.. -> "${PATH}:/Developer/usr/bin
In the case of cygwin, you'd just put the right directory to where make is.
This was confusing for me, so figured share the details that helped me. :)
