      @mzimmers said in Copying .dlls into target directory:

      libs_to_copy.files = $$(QMAKE_LIBDIR_QT)/libgcc_s_dw2-1.dll
      libs_to_copy.path = $$(OUT_PWD)/$$(OUTDIR)
      INSTALLS += libs_to_copy
      

      I don't get the error, but the file doesn't copy.

      What about this:

      libs_to_copy.files = C:/Qt/5.7/mingw53_32/bin/libgcc_s_dw2-1.dll
      libs_to_copy.path = $$(OUT_PWD)
      
      INSTALLS += libs_to_copy
      

      ?

      That gives me this error:

      :-1: warning: libs_to_copy.path is not defined: install target not created

      Alternatively you could try to add an additional target.

      I may have to fall back to this, if it turns out that the INSTALLS directive doesn't work.

      Thanks...

      Sorry, I might've mislead you. Try with:

      libs_to_copy.path = $$OUT_PWD
      

      Notice the lack of parenthesis. It's a bit cumbersome like this, but I don't have a windows machine on hand to test. If you continue to get an error run qmake with -d and attach the output, e.g.

      qmake -d myproject.pro

          No one does, perhaps with the exception of the qmake's developers. ;)
          Anyway, there seems to be a problem with the paths:

          DEBUG 1: C:/Users/mzimmers/Wideband/Peninsula/storefile_client/storefile_client.pro:17: libs_to_copy.files := /libgcc_s_dw2-1.dll
          DEBUG 1: C:/Users/mzimmers/Wideband/Peninsula/storefile_client/storefile_client.pro:19: libs_to_copy.path := C:/Users/mzimmers/Wideband/Peninsula/build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug
          ...
          DEBUG 1: Dependency Directories: ..\storefile_client :: . :: ..\ARM\inc :: C:\Qt\5.7\mingw53_32\mkspecs\win32-g++
          DEBUG 1: c:\Users\qt\work\qt\qtbase/qmake/generators/makefile.cpp:321 Failure to find /libgcc_s_dw2-1.dll in vpath ()
          DEBUG 1: no definition for install libs_to_copy: install target not created
          

          See that the dll file's path is truncated for some reason.

            Well, look at that...it sure is.

            I don't know what to make of that (so to speak). Is it possible we've uncovered a bug?

              It's probably one of those lovely windows gotchas, I think it does not like the dot in 5.7, try adding quotes

              libs_to_copy.files = "C:/Qt/5.7/mingw53_32/bin/libgcc_s_dw2-1.dll"

              and make sure you rerun qmake!

                Hi, Vronin -

                This is somewhat embarrassing. I tried your suggestion, and it worked. I looked at the compiler output and actually saw the xcopy command, and the file did copy.

                Unfortunately, it was copying to:

                C:\Users\mzimmers\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug

                instead of to:

                C:\Users\mzimmers\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug\debug

                So, I went in and fiddled with it, to no avail. I tried to put it back so it would at least re-copy, and...I can't make it work again!!

                I'm still encouraged, because it shows that the INSTALLS part of MinGW make does work. It's just a matter of getting the syntax in the .pro file correct.

                I'm trying to understand the libs_to_copy construct that I copied from somewhere else. This doesn't seem to be an ordinary qmake variable, and I can't get it to display using message(). Can you possibly point me to an explanation of it?

                Thanks a lot...I do think we're getting close.

                  Found it!

                  The problem was the trailing backslash in the definition of:

                  libs_to_copy.path = "C:\Users\mzimmers\Wideband\Peninsula\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug\"
                  

                  This occurs whether or not I enclose the path in double quotes. Seems like a bug to me...anyone disagree?

                  There's also the issue of why this line:

                  libs_to_copy.path = $$(OUT_PWD)
                  

                  results in an error message ":-1: warning: libs_to_copy.path is not defined: install target not created."

                  But, at least I've solved the problem that prompted me to start this thread.

                  THANK YOU TO EVERYONE WHO PARTICIPATED IN THIS.

                    It's not defined. Try $$OUT_PWD instead.

                      @kshegunov : yes, that was it. Thank you. I guess I'm still not clear on the rules of parsing variables.

                      I do have one remaining glitch: one of the three files I want to copy produces an error:

                      copy /y C:\Qt\5.7\mingw53_32\bin\libgcc_s_dw2-1.dll C:\Users\mzimmers\Wideband\Peninsula\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug\debug
                              1 file(s) copied.
                      copy /y C:\Qt\5.7\mingw53_32\bin\libwinpthread-1.dll C:\Users\mzimmers\Wideband\Peninsula\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug\debug
                              1 file(s) copied.
                      copy /y C:\Qt\5.7\mingw53_32\bin\libstdc++-6.dll C:\Users\mzimmers\Wideband\Peninsula\build-storefile_client-Desktop_Qt_5_7_0_MinGW_32bit-Debug\debug
                      The system cannot find the file specified.
                      

                      This file fails to copy whether it's the first, second or last file in the list. It also occurs whether I form libs_to_copy.files with three assignments, or one (multi-line).
                      Somehow I suspect it's the "+" in the filename. I made a copy of this dll without the "+" characters, and it worked. Is there some way to escape them in the string?"

                      Found this: it's a known problem. Not sure what to make of it...

                        This is due to a bug in Qt: https://bugreports.qt.io/browse/QTBUG-16372 but the solution is not easy to implement, see https://codereview.qt-project.org/#/c/85161/
                        This was the reason I first started using CMake as a build tool instead of qmake and now I wouldn't go back.

                        KDE is using Cmake.

                        An alternative (but I never tried it) is Qt Build system: http://doc.qt.io/qbs/

                              It's just a variable as far as I know. You can name it however you like and you (should) be able to use more than one as well. E.g.:

                              mingw_installs.files = "C:/Qt/5.7/mingw53_32/bin/libgcc_s_dw2-1.dll" "C:/Qt/5.7/mingw53_32/bin/stdc++6.dll" 
                              mingw_installs.path = $$OUT_PWD
                              
                              myown_installs.files = "C:/AdditionalDepDir/somefileIneed.txt"
                              myown_installs.path = $$OUT_PWD
                              
                              INSTALLS += mingw_installs myown_installs
                              

                              (do take my qmake knowledge with a grain of salt, though, I'm by no means an expert)
