How can I compile 64-bit Mac programs with Free Pascal?
64-bit, freepascal, macos
Solution
According to Jonas Maebe on the fpc-pascal mailing list, there are two options:
- Run `fpc` with the `-Px86_64` option. (The `-P` option does not appear to be documented yet.)
- Run `ppcx64` directly instead of `fpc`. (Without any options, `fpc` runs `ppc386` instead.)
Both worked for me.
Problem
I have an x86_64 library on my Mac compiled by GCC, and I want to link it with Pascal code compiled with Free Pascal 2.4. What options do I give to `fpc` to make it generate 64-bit code? Without any options, I only get 32-bit .o files. I'm using the fpc-2.4.0.intel-macosx.dmg download from SourceForge, but when I run `fpc -i`, the only target Macintosh platform it lists is "Darwin for i386," although the 2.4 release notes say it can target "64-bit Mac OS X (x86_64/ppc64)."
