For older distribution you can still use SDL1.2
./build.sh ... --sdl12 ...
or
cmake ... -DSDL2_API=FALSE ...
Note: there is a hard dependency between WxWidget and SDL. If Wx is linked against
SDL1.2, you must use SDL1.2. Crashes are expected otherwise.
Fixes a cmake detection problem when compiling with clang (3.7.0 in my
case). clang outputs the error "Invalid argument '-std=c++11' not allowed
with 'C/ObjC'", which causes lzma, Xext and other things to be
considered "not found".
Helpful for dropping dependencies package dependencies.
- Git only needed if there is a .git folder
- bzip2 only needed by CDVDiso
- CG/GLEW was for zerogs and ZZogl
- jpeg was for ZZogl
.
I also added that EGL_API is also for GSdx in option comment.
Debian has a goal to make reproducible builds therefore make it an
option instead of distro specific.
.
I added an "OR openSusE" to not "break" the old openSUSE behavior but ideally
they should just use -DDISABLE_BUILD_DATE=TRUE instead.
.
The old -DopenSUSE is not used for anything else so I removed it.
The goal is to reduce the burden for new architecture port.
Patch is mostly inspired from 3kinox initial patch. The diff are
*/ used ifdef instead of raw removal
*/ gui don't rely on UseMicroVU* option
*/ completely remove sVU_micro.* file
User may forget or not know about -DUSE_CLANG=TRUE. It could probably
be always autodetected instead of requiring user input.
.
Trivial wording changes to compiler_version.
Tell the user to use CMAKE_TOOLCHAIN_FILE upon failure.
.
Cleanup detectOperatingSystem. Should be the same but adding
GNU and kFreeBSD from Debian and filtering out pre OS X Apple.
.
libaio is linux only. Also check for the correct header since
aio.h is the POSIX one. Both are in /usr/include/ anyway.
Only build core if (Linux AND NOT AIO_FOUND) == false.
.
Use Unix for GTK and X11. Macs has gtk-quartzs and xquartz or native X11.
*BSD, linux, etc should have both.
The obtained binaries before and after this commit are identical (sha1sum)
when compiled in Debian/Ubuntu/Fedora/ArchLinux.
.
The linker will always pick the 32bit libraries the only thing this does is
make sure we have all the 32bit dependencies installed. Basically we avoid
detecting the 64bit libraries and telling the users the 32bit libraries were
found. We always link with 32bit libraries therefore this avoids having to
wait 5-10min to just be told -lXXX is missing.
.
The only thing really needed are
set(CMAKE_LIBRARY_ARCHITECTURE "../lib32")
set(CMAKE_LIBRARY_ARCHITECTURE ".")
.
which basically ensures we don't pick 64bit headers since
CMAKE_LIBRARY_ARCHITECTURE always gets tested first and for some reason
FindGTK2 test searches lib64 first then lib32/lib. These values are hardcoded.
Right now these arch specific headers are not used but can't say this will
always be true.
.
FIND_LIBRARY_USE_LIB64_PATHS is not needed for native builds and it's covered
by CMAKE_SYSTEM_IGNORE_PATH.
.
NOTE:
We filter out lib32 because multilib is not compatible with multiarch.
- Fedora only needs --arch if cross compiling.
+ It's only used to select libdir so i386=i686=i986
- Messages are nice to debug build logs.
.
Everything seems to work unless some other distro broke. Other
distros need to add CMAKE_TOOLCHAIN_FILE or --cross-multilib if
they cross compiled amd64 -> i686.
http://www.vtk.org/Wiki/CMake_Cross_Compilinghttp://www.cmake.org/cmake/help/v3.0/manual/cmake-toolchains.7.html
.
The official way that cmake does cross compiling is via the use of a
CMAKE_TOOLCHAIN_FILE. This has to be given by the user and can't be
included from within a Cmake file since setting up the toolchain has
to be the first thing that happens.
.
After the file is given and validated cmake behaves nicely and all the
workarounds and hacks are not really needed anymore.
.
The consequence of this change is that without this file cmake will
try to build for the HOST architecture as expected and with the file
it will build for the TARGET architecture of the given toolchain. Due to
this remove 64BIT_BUILD_DONT_WORK and just ERROR out if the user tries
in the same way as before.
Currently crosscompiling was broken since we detected the cpu of the host
not of the target. Building arm -> i386, i386->amd64, etc resulted in
interesting stuff.
.
CMAKE_HOST_SYSTEM_PROCESSOR and CMAKE_SYSTEM_PROCESSOR should have done this
but they are incredibly broken and unreliable. I use
CMAKE_HOST_SYSTEM_PROCESSOR just to retain the format of the old message
and is not used for critical stuff so it does not matter.
.
This code also allows scalability so that if one day in the very distant
and unlikely future the x86/x86_64 specific code gets made portable
by replacing asm/MMX/SSE*/AVX/etc code with generic/portable code then
it also would work on all architectures.
.
For *BSD/OS X it probably would need to use POSIX AIO instead of linux
specific libaio but that is a different issue.
.
Error out the x86_64 builds.
Also the 64BIT_BUILD_DONT_WORK option became obsolete more info in following
commit.
