    Hi,

    What about:

    GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -n 1 --format=%cd)
    

    ?

      Hello!! I am trying to use a commit date in my code. I am using this command:

      GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -1 --format=%cd)
      DEFINES += GIT_DATE=\\\"$$GIT_DATE\\\"
      

      When I use this variable in a .cpp, it seems that some of the command doesn't like qt, because it behaves as if it did not recognize the variable.

      648859d3-9134-4706-9d66-f66ee6dd1c55-image.png

      If I don't include the "-1" in the command, the error dissappears but the program doesn't compile I think because the output of the command is too long.

      How can I fix it??

      Thank you very much!

      @ivanicy What's the full error message that you get when you try to build? Your screenshot mentions a "unexpected expression" but the whole error message might include what the compiler thinks the expression is, which can be a useful hint about what exactly is going wrong. Also, if you are building verbosely with the compiler invocation, you'll also see the definition as it is passed to the compiler.

      I wouldn't be surprised if the ''s in your git invocation are resulting in an odd path being passed in '--git-dir' Windows?

          Please add a message($$GIT_DATE) in the pro file to debug the output.

          As @wrosecrans said, there might be a problem running the command or the output is not what you expect.

          Regards

            By the way, why are you passing --git-dir and --work-tree to that command ?

              @aha_1980 The output of the command in the General Messages tab is:

              Mon Dec 2 16:42:48 2019 +0100
              

              This is exactly that I want but when I use the variable in a .cpp, it gives me this error

                @SGaist I am not an expert in this commands. I found an example and it came with those modifiers

                  @wrosecrans When I build the project, The error that it throws is that there is a ")" missing. This is because the compiler can't recognise or can't use the variable. Let me show another command that works perfectly:

                  GIT_VERSION = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD describe --always --tags)
                  DEFINES += GIT_VERSION=\\\"$$GIT_VERSION\\\"
                  

                  This command gives the last tag and the number of commits after this tag. And, like I said, works perfectly.

                    Because GIT_VERSION is a string without any spaces.

                    You need to escape them all to use them in a define on the command line.

                    GIT_DATE = $$join($$list($$GIT_DATE), "\ ")

                      @SGaist Thank you very much!!! I changed the "\ " to "|" because it puts a blank and it works!

                        Hi @ivanicy,

                        why did you delete this topic? You should have rather marked it as SOLVED so others know that a solution has been found.

                        Thanks!
