Compile Qt 5.1.1 with Cygwin (64bit) shipped MinGW64 compiler on Windows 7

[Mr_Ada]

I ran into this before with the mkspecs. I want to compile Qt 5.1.1 so that I can get ".a" files I can debug with. I am writing Ada bindings and I have been a little successful in creating objects in Ada and passing it to the C++ world. Widgets and pushbuttons seem to be fine. Labels no. So if had Qt all "-g"d then I can traverse through the code to see if I am not converting something properly which is keeping the object from showing. I have tried to compile with windoze but no luck. I can't even get an SDK for XP64!

[Mr_Ada]

Also I had to do a dos2unix on the ascii files from the opensource file!

[sierdzio]

Mr_Ada If you download the source code as a .zip, it will have Windows line endings. If you want Unix ones, download the tarball.

And in general, if you want to do unix stuff, compile on Linux and you will save yourself a lot of trouble :)

To compile Qt with debug symbols, just pass -developer-build to configure.

[Mr_Ada]

I'll try the tarball on Cygwin but I'd still would like to be able to compile on Windows XP64 since I do a lot of my development on Windows. I'll go to linux (probably Ubuntu) and see if my bindings to Ada work there as well.

In older versions of Qt they provided debug libraries. Now it is a real pain.

That is the error I got. The files does exist where it says it does. My g++ is the Qt5 binary distributions at:

My configure command is:

[JKSH]

I'm not sure if you can use the Win32 (native Windows) variant of MinGW on Cygwin. You might need a copy of MinGW that was specifically built for Cygwin.

-I do know, however, that the configure script doesn't work on Windows, even within Cygwin. You'll need to run configure.bat instead.- EDIT: Sorry, I was thinking of MSYS, not Cygwin!

[Mr_Ada]

intersting! I would not have expected a DOS script to work in CYGWIN!

[JKSH]

Ack, sorry, I just realized I remembered wrongly. I was thinking of MSYS, not Cygwin! I've never tried compiling Qt on Cygwin before.

But like I said in your other thread, you'll probably have better luck doing a native Windows build instead of a Cygwin build which adds a POSIX layer to your system.

[/quote]That's a native Windows toolchain, so I doubt that works on Cygwin either.

What errors do you get when you try to compile in CMD?

[Mr_Ada]

Ok. My toolchain was wrong, so I fixed my path. Here is an output (I changed the folder name so that I didn't have it so long):

  'C:\qt_src\qtbase\configure.exe' is not recognized as an internal or external command, operable program or batch file

[Mr_Ada]

strange that it would look for an exe when there is a bat file there.

I think I am using the tarball source code. Maybe that is throwing things off....

  Don't go into 'qtbase'. Call configure.bat in C:\qt_src, and then call make in C:\qt_src.

[Mr_Ada]

first I had to resintall the Zip file instead of the tarball and I got a little further. It didn't like my -verbose so I took that out.

Then I ran it again and I got:
make.exe - Unable to Locate Component
This application has failed to start because msys-1.0.dll was not found. Re-installing the application may fix this problem.

What does msys have to do with all of this?

Also I am not going down to qtbase. I am calling this from the qt_src level.

[Mr_Ada]

so I cleaned up my PATH so only the one mingw toolchain was visible (Qt's).

Ran again and got this:

C:\qt_src>configure -prefix C:\Qt5d -debug -developer-build -opensource -confirm-license -static -platform cygwin-g++ -qt-zlib -qt-libpng -qt-libjpeg

• cd qtbase
• C:\qt_src\qtbase\configure.bat -prefix C:\Qt5d -debug -developer-build -opensource -confirm-license -static -platform cygwin-g++ -qt-zlib -qt-libpng -qt-libjpeg

This is the Qt for Windows Open Source Edition.

You have already accepted the terms of the license.

Creating qmake...
Cleaning qmake failed, return code -1

[Mr_Ada]

duh! I still have cygwin in there!!!!

changed to win32-g++

seems to be compiling...

[Mr_Ada]

got this:
Running configuration tests...
WARNING: The DirectX SDK could not be detected:
There is no Direct X SDK installed or the environment variable "DXSDK_DIR" is not set.
Disabling the ANGLE backend.

WARNING: Using OpenGL ES 2.0 without ANGLE.
Specify -opengl desktop to use Open GL.
The build will most likely fail.

config info...

then it said to:
Qt is now configured for building. Just run mingw32-make.

This doesn't exist in the tool chain. neither does make.

[JKSH]

You have two choices:

• Install the DirectX SDK, or
• Add "-opengl desktop" to your configuration flags (your graphics card drivers needs to support OpenGL 2.0 or newer).

In either case, make sure you clean your source tree first and the re-configure.

If you're using the copy of MinGW that came with Qt 5.1, then mingw32-make should be in the 'bin' folder together with g++

[Mr_Ada]

I added -opengl desktop and just did a make. Don't why it is compiling now but it is. I tried to re-configure but that didn't work but it is compiling which is a good sign!

[Mr_Ada]

Ok. it stopped compiling. Here is what it is complaining about:
