    • Qt Creator 2.7.2

      On Linux and Mac, compilation fails for library projects where the DESTDIR has been set to $$OUT_PWD during a shadow build in Qt Creator 2.7.2. This seems to be because the compiled .a file is first deleted in the DESTDIR directory and then the .a file is copied from OUT_PWD to DESTDIR. But since both directories are the same, the .a file is first deleted and then attempted to be moved, which obviously fails.

      I think the solution is to check if DESTDIR is the same as where the final output is generated, and if so, don't do the delete and move portion of the build. An example of the compilation output is below:

      But if I perform a non-shadow build, then the library is generated properly:
