      Hello.

      I am trying to compile Qt 5.7.0 Final from tar.gz Source Archive, as I need OpenSSL Support in my Application.

      The Steps I do are:

      • Open Yakuake
      • Switch to "/home/oliver/developing/xsdf64" (which is the out of source build directory)
      • Run the command
      /home/oliver/developing/qt5src/configure -opensource -confirm-license -prefix /home/oliver/developing/qt-build64/ -opengl desktop -debug-and-release -developer-build -openssl -icu -nomake tests -nomake examples -no-warnings-are-errors -platform linux-g++-64 -c++std c++14
      
      • And start compilation with "make -j 25" (which still dont fully utilize my old AMD 4 Core CPU)

      But now, after over 12 hours, the moving Output still repeats thousands of lines with

      /home/oliver/developing/xsdf64/qtbase/bin/qmake -qtconf /home/oliver/developing/xsdf64/qtbase/bin/qt.conf -o Makefile ../qt5src/qt.pro"
      

      This is the full config.summary:

      Some System Specs:

      • Antergos Linux x64 (Arch based)
      • KDE 5 / Plasma 5 Desktop (with some Qt 5.6.1 Modules pre-installed as needed by KDE5)
      • Python (3) and Python2 installed in parallel (which will become a Problem later as I need to compile QtWebEngine)
      • AMD Phenom II 4x 965 BE
      • 320 GB Free HDD Space
      • RAM: 1.6-1.7 GB of 15.7 GB used (with make - j 25)
      • SWAP Partition: 0.00 GB of 14.9 GB used (with make -j 25)
      • GCC Version: 6.1.1-2

      "Linux from Scratch" also recommend to set

      export CXXFLAGS=-fno-delete-null-pointer-checks
      

      to compile Qt 5.7.0 with GCC 6. But the Result makes no difference: under "xsdf64/" are still no "libs" and "include" folders.

      I cancelled compilation for now.

      This is the first time I try to compile Qt under Linux. I have some experience under Windows but this is a PITA. Any hint is welcome! :)

      Thanks
      Oliver

        I finally found the Problem. It is an absolutely dumb Problem:
        I unpacked the Source Archive to /home/oliver/developing/qt5src/ directly.

        Which means I dont have "qt-everywhere-opensource-src-5.7.0" as a Parent Folder.
        After re-unpacking the Archive and keeping the "qt-everywhere-opensource-src-5.7.0" as a Parent Folder, compilation is now running as it should.

        IMHO this is a Path finding Bug: I do the same under Windows and never have such Problems.

        What an idiotic "Error" :(
        Even after all these years, Linux has so many dumb usage Errors / Problems / Glitches etc.

          Hi,

          Since you gave a prefix, remove the developer-build option.

          Are you going to develop Qt ? If not then don't use the developer-build option.

            Hello.

            I am so used to use that "-developer-build" parameter and it is part of my prepared commands which I C+P to the CMD Window / Bash. I had to use it in a older Qt 5.x Version as "-prefix" got totally ignored.

            I simply never thought about it again.
            Thanks for the reminder :)

            EDIT01: Do you know by any chance how I can compile the Debug and Release Libs/Tools in one run? Or do I have to compile them after each other? "-debug-and-release" is not a valid command on Linux.

              Not valid ? What message did you get ?

                Configure says something like "-debug-and-release is deprecated now and works only on MacOS. You can build Release Libraries with included debug Infos".

                If I do for example "-release -debug" or "-debug -release", only the last Parameter gets set / used.

                Another Problem: I am also stuck with QtWebEngine and Python: Python2 and Python3 are installed in parallel (with Python3 as the Standard Python), and no matter what I try (i.e. setting an alias, setting an export in bash), the WebEngine config.tests only find Python 3. I will probably open another Thread about that in the WebEngine Subforum.

                I am back on Windows for now. Thanks for your time on a weekend :)

                  Ok, I missed that one. So you can either build twice or as proposed release with debug information.

                  I haven't built that module yet so I can't help you about that matter.

                  You're welcome :)
