[Libqtlua-list] QtLua Build VS2010 (now working)

[Jeff Sprenger]

I have made progress on the Windows build for QtLua,
and now have a working QtLua under Windows 7/64 built with Visual Studio 
2010.

1. I downloaded the svn official repository version (rather that the git 
version elsewhere). Alexandre pointed out that I was using the 
unofficial source.

2. The current CMakelists.txt files seems to be set for QT5. Since I had 
to build for QT4 (4.8), I changed out things like QT5_USE_MODULES and 
QT5_CPP_WRAP. More on this later.

3. I cleared out the build directory and ran CMake to create the Visual 
Studio solution and project files. This works after telling CMake where 
the appropriate Lua5.1 libraries are, also built for Win x64.

4. A few modifications to the QtLua code, mostly to export the necessary 
functions to the dlls by inserting appropriate _declspec(dllexport) and 
_declspec(dllexport) into the qtlua classes. Other  code modifications 
included changing out "foreach" loops, and array initializations using 
variables (ms compiler was not happy). Again, more details on this later.

5. I changed all project properties so that they could find the lua5.1 
lib and header files.

6. I built the basic console example in VS2010 with some changes:

- added to MainWindow() so that the console can recognize the QtLua and 
QtLib commands. Otherwise things like print() and help() fail.

        state->openlib(QtLua::AllLibs);

- preprocessor definition for qtlua project : added HAVE_QT_UITOOLS. For 
some reason, CMake fails to set this in the project file.

7. I built my own version of the console example using a fresh Qt 
Application in Visual Studio. This requires the Qt plugin for VS.
But there is a slight change to the lua script I tested (perhaps the 
example provided is outdated).

    spinbox=qt.new_widget("QSpinBox")

I changed this to:

    spinbox=qt.ui.new_widget("QSpinBox")

In a few weeks, I plan to write up the detailed instructions on building 
QtLua for Visual Studio on Windows and providing an updated example 
solution if anyone wants it.
I still need to work out why CMake is failing to set things like 
HAVE_LUA_GC and HAVE_UI_TOOLS correctly.
