The old implementation had two problems:
* OSTYPE and ARCH are systemwide defines, overriding them may break
the global libc headers. This is a theoretical problem, I've never
seen it in praxis.
* Not all system set ARCH correctly when building in a chroot env.
For example on Linux ARCH is set to x86_64 when building in an
i386 chroot. Now the user can do something like "make YQ2ARCH=i386"
to get things right.
The old whitelist was a leftover from the early days of YQ2. It should
run on most / all architectures, as long SDL supports them. As suggested
by smcv in issue #138 generate the OSTYPE and ARCH defines by the build
system instead of hardcoding it.
Savegame compatibility is provided by bumping the savegame version. Old
savegames are compared against the old OSTYPE and ARCH defined, new ones
against the new defines. This compatibility code should be removed
somewhere in the distant future.
Because setting both a default target directory and a configuration specific target directory wouldn't work as intended with multi-configuration generators.
As suggested by Daniel, use the same hack as dhewm3: The user defines a
path prefix and CMake does the rest. So this is enough to build on
Windows: cmake -G Unix\ Makefiles -DYQUAKE2LIBS=C:/MinGW/32/LIBS ..
This is a working CMake based build system for Windows:
- While this should work with system wide installed libraries, it's
still highly recommended to use the latest version of our official
Windows build environment.
- It was tested with out official build environment on Windows 7 with
32 bit and 64 bit builds
- You'll need something in the lines of this nice and short command:
cmake -G Unix\ Makefiles \
-DSDL2_LIBRARY=C:/MinGW/32/LIBS/lib/libSDL2.dll.a \
-DSDL2_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
-DZLIB_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
-DZLIB_LIBRARY=C:/MinGW/32/LIBS/lib/libz.a \
-DOGG_LIBRARY=C:/MinGW/32/LIBS/lib/libogg.dll.a \
-DOGG_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
-DVORBIS_LIBRARY=C:/MinGW/32/LIBS/lib/libvorbis.dll.a \
-DVORBIS_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
-DVORBISFILE_LIBRARY=C:/MinGW/32/LIBS/lib/libvorbisfile.dll.a \
-DVORBISENC_LIBRARY=C:/libvorbisenc.dll.a \
-DOPENAL_LIBRARY=C:/MinGW/32/LIBS/lib/libOpenAL32.dll.a \
-DOPENAL_INCLUDE_DIR=C:/MinGW/32/LIBS/include ..
Yes, forward slashes! Backslashes will break!
