Re: [Mingw-cross-env-list] which package provides QT4 qmake.exe

[Rashad M]

Hello,

As Martin, said cmake check for qmake , rcc etc. If you have a gui applications with translations  it needed lupdate, lrelease.exe also.

I think, mxe is not suitable for building development packages (dll+headers)
for using in Windows. The most important issue will be non-portability for C++
dlls across compilers (C dlls might work though).
The qt dlls might be usable using a similar MinGW compiler on Windows. But if
you use MSVC, your qt dlls from mxe will be useless, since MSVC could not link
them.

I used them build my project. I installed cmake, mingw-64 (7zip archive from sourceforge) and along with the mxe target dir containing all dll and headers. It is working without any issue.

For the Qt one which I have a fix for which I am not so proud of. But I thought to share in case if someone finds useful.

I copied the source of qt4 from mxe/src/qt-opensource-everywhere-4.8.6.tar.gz to  my windows.

I extracted it and compiled only qmake, moc, rcc, uic, lrelease.  These does not link to any other Qt specific library. So I guess I am safe as long as I use a mingw compiler to do the task on windows.

The qmake executable is not native for Windows, since it is a qt installation
for cross compiling. You compile your project on *nix and run it on Windows.
For compiling on *nix you need a qmake executable which runs on *nix.

You could try to cross compile your whole project using mxe.
I use CMake successfully for cross compiling a lot of my projects.

If you need a ready-made Qt installation for Windows, there are pre-built
packages available from the qt website.

If you still want to compile a qmake.exe from mxe, there might be configure
options for the qt library, but I doubt that.
