There is now a separate iphonesim target that can be used to target iPhoneSimulators that use the Objective-C 2.0 ABI. In short: a) build the i386 compiler normally and install it b) build the iphonesim units: make FPC=installed_ppc386 OS_TARGET=iphonesim all c) install the iphonesim units: sudo make FPC=installed_ppc386 OS_TARGET=iphonesim install CROSSINSTALL=1 Next, you will also have to modify the Xcode build scripts (under the "fpc" target) so that a) the "build libfpc.a" and "Compile Pascal Sources" phases use the units from i386-iphonesim instead of i386-darwin when compiling for i386 b) the "Compile Pascal Sources" phase adds "-Tiphonesim" to the compiler options when compiling for i386 The iphonsim target defines both "darwin" and "iphonesim", so you can use {$ifdef darwin} for common code and {$ifdef iphonesim} for iphonesim-specific code. |
|
|
One more thing: step c) will also install a "ppcross386" compiler. You can ignore/delete it, as it is not different from the regular ppc386 installed during step b). You do *not* need it to compile iphonesim binaries, because any ppc386 compiler can always generate code for all i386 platforms. |

Not i have error when try to install iphonesim units: make FPC=installed_ppc386 OS_TARGET=iphonesim all Result: ... fpcmake -p -Ti386-iphonesim Makefile.fpc Processing Makefile.fpc Error: No targets set make[3]: *** [fpc_install] Error 1 make[2]: *** [rtl_distinstall] Error 2 make[1]: *** [installbase] Error 2 make: *** [install] Error 2 |
|
|
After the "make all" and before the "make install", copy utils/fpcm/fpcmake to /usr/local/bin |
|
|
Actually, the step a) in my instructions should already have updated the global fpcmake, so I'm not sure why it's not working for you. |
|
|
Does "which fpcmake" return /usr/local/bin ? |
|
|
I've now added "CROSSINSTALL=1" at the end of the iphonesim install line (point c), so that it will not overwrite the existing fpcmake and other utilities. However, that cannot have caused the problem because those binaries (obviously) also contain iphonesim support (and they're also plain i386 binaries, although they'll only run on 10.5 and later). |
