[Marble-devel] HOWTO (in progress) - build a libmarble application on windows with Qt Creator, MinGW, CMake

[Sylvain Paré]

Hello every one,

As I told it some times ago I am trying to build my application using
libmarble on windows(xp) with Qt Creator.
I will post here all the whole process and problems encountered gradually.
You are welcome to help me to solves those issues if you have answers! :)

At last when the work-through will be found, I will sum it up here as a
proposal for an HOWTO on the KDE Techbase.

So here is the beginning until the first blocking point :

First build Marble:

   - installation of Qt sdk
2010.02.1<http://get.qt.nokia.com/qtsdk/qt-sdk-win-opensource-2010.02.1.exe>(Qt
Creator 1.3.1 Qt 4.6.2 MinGW 3.15 GCC4.4.0)
   - installation CMAKE
2.8.1<http://www.cmake.org/files/v2.8/cmake-2.8.1-win32-x86.exe>,
during the installation check the box " Add CMake to the system"
   - following this http://edu.kde.org/marble/obtain.php => svn co marble;
   create 'marble-build' dir in the new checked out folder
   - as explained
here<http://doc.qt.nokia.com/qtcreator-1.1/creator-cmake-support.html>import
the marble\CMakeLists.txt passing "-DQTONLY=ON ../" argument
   - you obtain this message error :

CMake Error: CMake was unable to find a build program corresponding to
"MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to
select a different build tool.

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

   - I haven't found yet how to solve this (i.e indicate to CMake the path
   of MinGW, I set an environment variable but it did not fix this.. if you
   have the answer.) properly so I just copy/paste C:\Qt\2010.02.1\mingw  to
   C:\mingw
   - now when you retry to import your cmake project in Qt Creator you have
   this error :

-- The C compiler identification is unknown

-- The CXX compiler identification is unknown

-- Check for working C compiler: C:/mingw/bin/gcc.exe

-- Check for working C compiler: C:/mingw/bin/gcc.exe -- broken

CMake Error at C:/Program Files/CMake
2.8/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):

The C compiler "C:/mingw/bin/gcc.exe" is not able to compile a simple
testprogram.

It fails with the following output: Change Dir:

   CMake will not be able to correctly generate this project.

Call Stack (most recent call first):

So here where I am!

If any one can help...

I will continue to search a solution tomorrow
