[Libqtlua-list] QtLua Build VS2010

[Jeff Sprenger]

I need help building QtLua for Windows.
If you're interested in a Windows build or have done this successfully, 
please read on.

Environment
I am building on Windows7/64 bit, using Visual Studio 2010 professional. 
I feel like I'm almost there.
(I understand if people hate that environment and recommend a g++ linux 
build or mac build, but this is not a choice for me - it's a requirement)
I cloned the git repository to get a copy of the source.

Background
I've read previous posts by Alexandre Becoulet, Evan Comes and Gedalia P.
AFIK, no one has successfully built QtLua on Windows using Visual Studio 
and the MS compiler.
I tried earlier to build Qtlua using cygwin with CMake and mingw-32, but 
got nowhere. Seems that cygwin and CMake don't always play well together.

Problems

1  b. In the QtLua code, the function State::gc_collect() calls 
lua_setgcthreshold() if HAVE_LUA_GC is not set.  This function exists in 
Lua 5.1, but for some reason HAVE_LUA_GC is not getting set correctly in 
the CMake config - not sure why. I can easily work around this.

2. No Exports: Building just the project "qtlua" in Visual Studio does 
succeed and outputs qtlua.dll but not the import library (qtlua.lib). 
When I try to build ALL_BUILDS (the other projects that are part of the 
solution) the builds fail because the other projects can't find 
qtlua.lib.  It seems this happens because there are no EXPORTS in the 
qtlua.dll.
It seems to me that we have to indicate which classes to export by 
declaring classes / function with __declspec(dllexport)). Either that or 
supply a .def file indicating a list of EXPORTS.
If anyone can provide guidance here , please do.

Any help is welcome. I will fully document the build process once I get 
it to work and share it here, so that others do not have to wander 
through the same abyss.

Thanks,

Jeff S.
