Instead of compiling a binary for each arch and then join them in the end, each .o file is now compiled as a fat file
This means that the makefile will not call itself to make a binary for each target and we don't have to make clean between each build
it also means that if one file changed, we don't have to recompile all files
Another benefit is since it's handled at .o level and though LDFLAGS, no special code is needed if we decide to compile more binaries (like a lot of stuff used to happen at post linking)
We also needs much less flags to set up, so it should be even easier to get to work out of the box now
The tradeoff in doing so is that now the binary needs at least OSX 10.3.9 to execute
To deal with this issue, the JAGUAR flag can be used to compile for older OSes. We will release a binary for old OSes at next release to see if anybody even downloads it (not that many people use OSX 10.2 anymore)
GPMI will not work on 10.2 anyway so we will cut support for it some day anyway
G4 have no problems using G3 code while G5 can, but really benefit from getting their own optimised code (Apple: G5 is not just a fast G4)
Also changed FAT_BINARY to UNIVERSAL_BINARY since Apple removed most (all?) references to fat binaries on their homepage two days after I added FAT_BINARY
Now OSX users can tell what lines in the C code that keeps the CPU busy instead of just ASM code
Note: PROFILE needs to be enabled in Makefile.config for this to work
you can still use SDL drivers if you like and you have to run "make upgradeconf" to start using the cocoa drivers (or manually write WITH_COCOA:=1)
since SDL breaks the cocoa drivers, you can't compile with both SDL and cocoa support
Using cocoa drivers makes it easier to make universal binaries and it solves:
-FS#18 [OSX] SDL is weird in universal binaries
-FS#2 [OSX] lazy pointer crash on exit
-FS#10 [OSX] linking error when linking statically to SDL 1.2.8 (needless to explain this, but it means it should be able to compile statically with the default settings now)
-[ 1215073 ] Switching to large size out of fullscreen crashes
Using SDL drivers will still have those issues though
now PPC code is always compiled before x86 code
strgen and lng files are only compiled once, which results in shorter building time
the makefile now assigns default values to undefined values so much less needs to be set up
the code is now easier to maintain
this means that ENDIAN_FORCE is obsolite since it's always overwritten with PREPROCESSOR
Since the preprocessor should never be able to pick wrong, it's easier this way
specially when compiling universal binaries as they got both endianess
it needs both PPC and x86 libs to compile
due to this fact, compilation with libPNG or SDL is not tested (dedicated servers only)
only PPC part is tested as I don't have x86 OSX
This is not a fix for the issues with static linking, more like a workaround. Static linking still got issues
Apple recommends to use dynamic linking anyway, so I guess this doesn't matter much
max_autosave_num in the config files sets the number of autosaves to keep (default 16)
MAX_NUM_AUTOSAVES in Makefile.config sets the default value. 16 is used if no value is given
this behaviour can still be overwritten by keep_all_autosave (openttd.config setting)
Note: this is a requested behaviour for PDA ports, since they got limited storage space
This removes all the 64bit stuff from the Makefile. Everything should
work just fine. Also removed the warning on amd64, 64bit OpenTTD is
stable. Tnx to dst for commenting and testing on this subject.
