I've read quite a bit about it but nothing is exactly specific to this one point...

do I use the same command lines in my makefiles/gcc command line...

that one would use to compile under MorphOS for the Peg2 for instance?

I'm speaking about the exact cpu parameters I should be executing... I mean, I know it wouldn't be something like -cpu=750 for example...

should it be something like... -elf32 -morphos...

what are the defaults of the MOS hosted MOS targetted gcc environment?

anyway, sorry about the gibberish, I'm sure you who knows knows what I mean ;)

I just want to know what I should be putting to generate code that'll work correctly or more specifically with MOSPU for MOSPU...

my specs are a 233mhz/060 if it has any bearing on anything... perhaps I could use a -cpu=233 command...

btw, the commands are probably not correct but that is because I am tired and haven't remembered the syntax since I lost interest since I couldn't register...

things change... thanks for your interest and help :D

Yes.

Neither of those two exist ;)

The default is to create PPC code with System V ABI and output ELF files

The -mcpu option doesn't really matter much in my experience, better avoid using it. It'd be -mcpu=604e if you really wanted to.

Anyway, to compile a file with optimisations for Ixemul, you'd use gcc -O2 -Wall myprogram.c -o myprogram. If you want to use Libnix instead (and you probably do), then add -noixemul to that line.

Yes you do.

Nothing needed. Just remember to use -noixemul switch when compiling your stuff:

gcc -noixemul -O3 foobar.c -o foobar

I used -mcpu=604 when I was compiling on my PowerUp system and now -mcpu=750 switch on Pegasos but they probably dont make much difference. Both code work on MOSPU and generated code is almost the same.

gg:guide/gcc.guide is interesting reading btw.

@bigfoot

Poeh.

(Seems this forum is broken... I lost my umlauts.)

thanks very much!

btw... can we use amiga gdb 4.16 on MorphOS? I know it can't perform core dumps but it has its uses and there doesn't appear to be MOS port...

Only for 68k software, i think, but i don't think it will work at all (because it uses exceptions, which is not emulated/taken over by MorphOS, i guess).

And yes, unfortunately there's no finished/working/released (choose one) version of GDB for MorphOS yet(?).

Indstead, try to use builtin debug facilities on MorphOS. It's not that confortable as GDB, but useable. For a detailed description read this.

That is the default if no -mcpu= was given :) FWIW, for PowerUp I would recommend -mcpu=603e.
