musescore qt creator compile not finding gch.cmake
This is a developer query. I'm following your page in the Musescore developers handbook - Compile instructions (Windows - MinGW) - Git. Everything works fine and I have got Musescore 2 beta to compile using the command line. However the final (crucial) debugging section using Qt Creator IDE does not work as it specifies. So far I'm not so familiar with QT Creator, but when I follow the instructions to open CMakeLists.txt and add the arguments
-DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_TOOLCHAIN_FILE=../build/mingw32.mingw.cmake
I get errors
CMake Error at CMakeLists.txt:21 (include):
include could not find load file:
C:/musescore/ms/mscore/build/gch.cmake
The compiler seems to be looking for the /build folder as a subfolder to mscore which of course it isn't - it's off /ms. I've tried everything I can think of to tell it to read C:/musescore/ms/ as the project directory but to no avail. Can you tell me how to get this to work?
Many thanks for your help.

I updated the instructions.
Don't choose CMakeLists.txt from
mscore/but from the root directory. Also change-DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_TOOLCHAIN_FILE=../build/mingw32.mingw.cmaketo
-DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_TOOLCHAIN_FILE=build/mingw32.mingw.cmakeI look forward for your first pull request!

Hi, and thanks for the feedback. I have tried using CMakeLists.txt in the root folder with amended arguments as you suggest, and now I get
CMake Error at C:/Program Files/CMake 2.8/share/cmake-2.8/Modules/CMakeDetermineSystem.cmake:95 (MESSAGE):
Could not find toolchain file: build/mingw32.mingw.cmake
The file build/mingw32.mingw.cmake is present. Any ideas?
Thanks

Try removing CMakeLists.txt.user in the root directory. It's created by Qt Creator and might have some things cached.

There doesn't seem to be a file CMakeLists.txt.user in the root. Here's the complete error list I'm getting now.

Does any of this suggest a solution? Do I have to set up anything special in Qt Creator itself?

I guess you could put the absolute path of the toolchain path instead of build/mingw32.mingw.cmake but still, it's weird. I just tried and it's working. You should have something cached somewhere.

Could you be using an old version of CMAKE? I found that a recent commit (for WINE.BAT and WRT.BAT) required the latest CMAKE so I installed 2.8.9.

Ok. My fault, I hadn't done a full reboot after installing and changing the paths. This is the second computer I tried this on and of course I did all that on the first one but it still didn't work. Now it's finding mingw32.mingw.cmake in the \build folder. However it's now failed on the next step
CMake Error at CMakeLists.txt:134 (message):
Fatal error: QT (version >= 4.8.0) required. Cmake tries to detect QT4 by
searching for 'qmake' in your PATH.If you have QT4 installed, make sure
qmake is found in your PATH. If you compiled QT4 yourself make sure your
new qmake is found _first_ in your PATH.
The path for qmake is in the PATH statement - C:\QtSDK\Desktop\Qt\4.8.0\mingw\bin; but it still doesn't find it. I'm already using CMake 2.8.9. Any idea what could be the cause of this?
After the above error it continues

qmake is not in your PATH or at least not in the PATH of the QtCreator process when you run it.

I hadn't added the path to CMake to the Qt Creator field in Build and Run. Once I did that it found everything and compiled the program. Thanks for your help.
However, when I hit the Debug button it immediately comes up with the error
During startup the program exited with code 0xc0000135
Is this a known problem, or is there something which hasn't compiled properly? The were quite a few red and amber warnings.
In reply to Finally success, but by truebrit57
My fault - forgot to add libogg.dll etc to the mscore folder. Now everything opens up in the debugger and I can follow it through line by line.
Many thanks for your help. I hope it's not too long before I've got it all under my belt.
