    Hello, newbie here. There is a library that I want to use but it comes with vague instructions to use QT and MinGW to build it with a Makefile in Win 10

    First I installed QT and I entered in on the command line

    //Initial Attempt
    
    C:\Users\Be\Downloads\VirLe-v1.0.2-src\virle-36c567b992a6\src>D:\Qt\Qt5.7.1\Tools\mingw530_32\bin\mingw32-make.exe -f Makefile
    
    qmake -o Makefile.VirLe VirLe.pro
    process_begin: CreateProcess(NULL, qmake -o Makefile.VirLe VirLe.pro, ...) failed.
    make (e=2): The system cannot find the file specified.
    Makefile:22: recipe for target 'Makefile.VirLe' failed
    mingw32-make: *** [Makefile.VirLe] Error 2
    

    I figured maybe it wasn't working because I wasn't doing it directly in the command line so I started up the MinGW shell and retyped the commands.

    D:\DocumentArchive\VirLe-v1.0.2-src\VirLe-      36c567b992a6\src>D:\Qt\Qt5.7.1\Tools\mingw530_32\bin\mingw32-make.exe -f    Makefile
    
    qmake -o Makefile.VirLe VirLe.pro

    It looked like I had a version of QT that was too new so I installed QT 4.8.6 and tried again.

    Can anybody give me an idea what might be going wrong?

      Hi and welcome to devnet,

      The qt3support error indicates that it's a library ported to Qt 4 that wasn't completely ported.

      From your other error, it looks like the Makefile is done for Linux rather than generic.

        @A123 In the final make attempt the Makefile is trying to use g++ which of course is not mingw32-g++. You could change that in the makefile to use mingw32-g++, and it may get you further.

        This is going to be a tough thing to get working though it looks like it has pretty limited windows support. Like it's an after thought and not something that is maintained well by the developers.
