I'm attempting to port FPC to Freebsd/PowerPC64 and need some help.

I've added initial code to get started. However, when trying to cross compile I'm getting an internal error message when the newly created cross compiler (ppcrossppc64) executes.

/root/Downloads/fpc-3.2.0/compiler/ppcrossppc64 -Ur -Ppowerpc64 -XPpowerpc64-unknown-freebsd11.2- -Xr -XX -CX -Ur -Xs -O2 -n -Fi../inc -Fi../powerpc64 -Fi../unix -Fi../bsd -Fi../bsd/powerpc64 -Fi../freebsd/powerpc64 -FE.
-FU/root/Downloads/fpc-3.2.0/rtl/units/powerpc64-freebsd -dpowerpc64 -dRELEASE -CaDEFAULT -Us -Sg ../bsd/system.pp
sysos.inc(69,12) Fatal: Internal error 2015021001
Fatal: Compilation aborted

Can someone help me decipher this? I've attached the fpc debug file, if that will help.

Regards

Hi,

You can just search the source for that IE number as string. It will reveal, that you failed to specify a default ABI for the target system. This error seems to be PPC64 specific.

See systems/t_linux.pas for an example, and do something similar in the PPC64 FreeBSD port.

Cheers,

See systems/t_linux.pas for an example, and do something similar in the PPC64 FreeBSD port.

You should also set the ABI in systems/i_bsd.pas already. The code in t_linux is because of the support for both big and little endian PowerPC64 (which FreeBSD also has, so you'll indeed have to do the same there).

I've resolved my initial issue. It was something included in the command-line that was causing the error.

I'm trying to use the unmodified linux/powerpc64 files with freebsd. When building bsd/system.pp I get the following:

I'm a novice programmer, so any suggestions on what to look at or how to fix this?
