  @user2301
  That's what I was thinking would be the case, any why I told you to try a RUN ["cmd", "/c", "set"] after it to show what the actual state of environment variables is.

  In Windows/DOS (and in Linux too), environment variables set in a shell only last as long as that shell (and any processes it spawns). So if your RUN command spawns a new shell for each command and exits it each time, those variables won't have been set for a subsequent RUN ["qmake"]. (And if that's true, maybe it only works on your earlier PATH changes because RUN $env:PATH does something special with that leading $env?)

  So you need to look up how you're supposed to achieve this environment variable changing stuff from a Docker script or whatever.

  @jsulm said in Why there is no x64 option for Qt tools on Windows, when using unified installer?:

  @flashmozzg Interaction with 64bit tools/environment? I don't see how this can be a problem. Never had any problems with 32bit QtCreator. x86 limitations are only real limitations when you actually hit those limitations. But I agree that a 64bit version should be provided by default these days.

  Well, for example, I had some build scripts broken because they were launched in x86 compatibility mode (so certain Windows features/exes were "hidden" from them), and it wasn't easy to debug what's wrong. It was fixable, but still avoidable.

  Mostly it was just unexpected, since Qt Unified installer doesn't offer x64 and doesn't mention that QtC would be x86. It didn't even occur to me to look in that direction until I've hit my problem.

  Also, since unified installer doesn't allow you to "deselect" QtC and it'll try to install over x64 one the user experience is awful. Basically, it seems there is no way to use unified Qt installation with x64 QtC without some ugly hacks/redundant x86 QtC copy.

  @SGaist

  My .pro file has so many things which is due to multiple stuff and it would not make much sense to share it here. But I have set QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.12 and QML_IMPORT_PATH is set to nothing. Plus, following are some more settings I have in my .pro which might be relevant to this question

  CONFIG += c++14 CONFIG -= bitcode

  I am marking this Topic as solved. Do let me know if have a suggestion on this last error.

  Hi and welcome to devnet,

  @medihe said in Removing Qt3support:

  I am not sure if I understand you correctly. Do you mean I can compile a project with q3support libraries with a qt5 compiler?

  There's no Qt compiler. Qt is a C++ framework. And no, the Qt3Support module is only available in Qt 4 as a transition helper. Update your code to get rid of it.

  So I clear everything with:
  git clean -dfx and
  add -no-gbm to configure.

  ./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=/root/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot /root/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix /root/raspi/qt5pi -hostprefix /root/raspi/qt5 -no-use-gold-linker -v -no-gbm

  and make again ,it's work

  how did your Qt configure call look like. Or even more interesting it's output.
  There is probably a note that PNG support isn't available? You system might miss some libraries for built-in PNG support.

  Ok, solved! for those having problem compiling with NDK r18 the following files must be modified:

  qtbase/mkspecs/android-clang/qmake.conf:

  In QMAKE_CFLAGS change

  --sysroot=$$NDK_ROOT/sysroot

  with

  --sysroot=$$ANDROID_PLATFORM_ROOT_PATH

  and add -isystem $$NDK_ROOT/sysroot/usr/include at the end.
  And in ANDROID_CXX_STL_LIBS change -lc++ with -lc++_shared.

  qtlocation/src/plugins/geoservices/geoservices.pro:

  Remove all lines related to qtConfig(geoservices_mapboxgl).

  I SOLVED, this is how mi app start to wok in other PCs:

  The problem was when I was reading a file in my program at a specific path (example: C:\Program Files (x86)\TestQT1\test.txt) and when I execute the .exe file from another PC, the path was slightly different and it was crashing at the beggining.

  I know this is a very old post at the time but I was looking for the same problem so hard and I spent a lot of time to find this issue, so I hope this information will be usefull for any other people

  When you have a license and they helped you in compilation for static Qt libs, they have to know best what information they supplied.
