Question

Please tell me, what is the location of stdlib.h in XCode 4.3 ?

Was it helpful?

Solution

What was in /Developer in Xcode versions prior to 4.3 is now within the Xcode.app bundle. There are several, one for each supported SDK and Platform:

$ find /Applications/Xcode.app -name stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/include/c++/4.2.1/tr1/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/include/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/usr/include/c++/4.2.1/tr1/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/usr/include/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/usr/include/c++/4.2.1/tr1/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/usr/include/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/include/c++/4.2.1/tr1/stdlib.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/include/stdlib.h

OTHER TIPS

If you install the command line tools (Xcode > Preferences > Downloads), then the file is present at/usr/include/stdlib.h.

I think you should be using unistd.h instead of stdlib.h. I had an issue trying to use sleep() when importing stdlib.h and I had to import unistd.h.
