Do you know where it's > supposed to be generated at? In the directory from which you've invoked gcc. So in your case: cd /tmp/phantomjs/src/qt/qtwebkit/Source/WebCore g++ --save-temps -c -Wall -Wextra -Wreturn-type ... (from comment 0) You'll find JSBindingsAllInOne.ii in /tmp/phantomjs/src/qt/qtwebkit/Source/WebCore
