I want to compile my application but get an error that "stdio.h: No such file or directory". I checked and verified that "build-essential" is installed. Then I searched for this files and found many locations for it!! since some of libraries that I have installed for my work has their own stdio.h!!. How can I found that which stdio.h is compiler looking for? -- View this message in context: http://old.nabble.com/How-to-find-right-header-files-when-multiple-versions-are-exist-tp27367117p27367117.html Sent from the gcc - Help mailing list archive at Nabble.com.
