When I compile my project as debug, it works normally, but when I try to compile in release appears the following message in the Output Compile:

cc1plus: error: argument to '-O' should be a non-negative integer, 'g', ’s' or 'fast' make: *** [main. o] Error 1 ... The process "/usr/bin/make" exited with code 2.

Error while building/deploying project 'project name' (kit: Desktop Qt 5.4.0 GCC 64bit) When executing step "Make"

Would anyone know why?

    The problem is probably in your .pro. Add it to your question. Also add the command line being executed at the time of the error.

  • I had this problem a while back, but I really don’t remember how I solved it.

The problem for the following reason, because my application is cross-platform (windows/linux), I added:

-QMAKE_CXXFLAGS_RELEASE -= -O2

-QMAKE_CXXFLAGS_RELEASE += -Od

To remove messages from my compiler C windows, but did not tag win32: in these lines and the linux c compiler did not understand, after adding it, it worked correctly.

    @Giovaniracipaganini yes, but only after two days after posting the reply.

  • Ah yes, I had forgotten hehe.

  • The good answer, unfortunately no one would be able (I think) to answer why there was no code .pro as Vinicius requested. But still good tip :)

  • @Guilhermenascimento agrees with his statement, but as soon as the friend Vinicius commented I looked at him. pro and then I noticed the error, so I saw no need to post the wrong part in the question but an answer already with the solution.

  • Yes, that’s not really what I mean, what I mean is that I always post relevant codes following these tips: http://answall.com/help/mcve :) In the case of the next questions that you will make

  • @Guilhermenascimento yes, thank you very much for your suggestion.
