Re: [B2-devel] MacOS X builds

[Gwenole B. <gb....@fr...>]

Hi,

The necessary changes are now available in CVS. Some docs have yet to  
be updated though. Here are the new build instructions.

$ cd src/MacOSX
   Everything is built under the MacOS X tree (though building from  
Unix still works with SDL support)

$ NO_CONFIGURE=1 ../Unix/autogen.sh
   This regenerates the configure script with the in-source m4 macros  
(yes, 1_prepare_files.sh is dead)

$ ./configure --enable-jit-compiler
   This configures Basilisk II with JIT compiler enabled, provided  
your are using an x86 platform (single binary build)

$ ./configure --enable-jit-compiler --enable-universal
   This configures B2 to build Universal Binaries on supported  
platforms (x86, ppc). You can select other arches, e.g. --enable- 
universal="ppc i386 x86_64" though I don't have Leopard to test

Note that you need to build B2 from an x86 platform though it could  
work the other way around. This automatically selects the oldest  
cross-compiler to ppc, preferably the 10.2.8 SDK. You can choose  
another SDK version through the --with-ppc-sdk=VERSION option where  
VERSION is 10.2.8, 10.3.9 or 10.4. Comments welcome.

BTW, REAL_ADDRESSING mode also works with a full MacOS X build. I  
have verified so with a FAT binary on both x86 and ppc.

Some *_macosx files are not 64-bit clean yet though I have added  
support for x86_64 to the SIGSEGV library. Someone with Leopard may  
want to submit patches within the next two weeks. Thanks. ;-)
