Hello!

Could someone help me with MOS GCC crosscompiler for m68k, please?
I found it on Aminet (m68k-amigaos-gcc2.95.3.tar.bz2), but there's no information how to install it and make it useable.

IIRC all you have to do is unpack it in your GG dir, though you better unpack it somewhere else first just to check that it won't overwrite anything important.

Additionally you might need to grab some AOS includes (and tweak them to work with GCC (as well as generate inlines)) and stuff them in m68k-amigaos/os-include or whereever they went again...

Unpacking the archive directly might clobber c++ includes. AFAICT, this archive is pretty old and thus the includes are very likely older than then ones from a current MOS native GCC.

Quote:
Only native AmigaOS-style compilers have an "os-include" directory ;-) For cross-compilers these special OS-includes are placed in <target>/sys-include and the normal C includes in <target>/include.

However, this archive has a surprising layout because all programs normally found somewhere in bin/ are placed in the compiler directory...

First of all, thanks for your answers!

I copied all archive contents beside /include/g++-3/ (this directory
has been already exist in my GG:). I also copied OS3.9 includes to
GG:m68k-amigaos/os-include. Then in my makefile I set CC variable to
GG:lib/gcc-lib/m68k-amigaos/2.95.3/gcc
When I'm trying to make a project, I'm getting this message:
Assembler messages:
Error: invalid switch -mc68010
make: *** [o/clipboard.o] Error 1

What should I do now?

You need to grab the crosscompiling binutils as well...

You need to grab the crosscompiling binutils as well...

There are one (2.13.1) flying around, but are broken. Alternative way (tried by me) is just using m68k native 2.9.1 binutils.

Do you mean 2.13.1 binutils from Aminet? I tried it, than I used 2.8.1
- from Aminet also (BTW: where can I find binutils 2.9.1?). This
time before copying file from /bin to GG:bin I renemed files adding
"m68k-amigaos-" string at the begining.

Unfortunately in both cases I get error:
/gg/m68k-amigaos/bin/ld: cannot open -lamiga: No such file or directory
collect2: ld returned 1 exit status

I don't have amiga.lib anywhere in GG: - also in ppc-morphos stuff.
But I can compile for MorphOS without any problems. Could anyone help?
I hope that's my last problem related with m68k crosscompiling. ;)

Using Snoopium I managed to avoid "cannot open -lamiga" problem. I
renamed amiga.lib from OS3.9 SDK to libamiga.a and copied to
GG:m68k-amigaos/lib.

Then I needed some inlines. First one for muimaster.library. I
generated it with fd2pragma from Aminet. After that GCC started
complain about macros inline. There was a problem, because there is a
clib/macros.h in OS3.9 SDK, but not fd/macros_lib.fd. Luckily I've
found needed inline (and many others, which I copied to my inline
directory) in this archive:
http://it.aminet.net/dev/gcc/fd2inline-bin.lha

Now I have different problem while linking. With MOS binutils version
I've got:
/gg/m68k-amigaos/bin/ld: BFD 2.13.1 internal error, aborting at ../../binutils-2.13.1/bfd/amigaoslink.c line 259 in get_relocated_section_contents
/gg/m68k-amigaos/bin/ld: Please report this bug.
collect2: ld returned 1 exit status

and for m68k version it is:
ld terminated with signal 6

Any ideas?...

FWIW, I would suggest to avoid both versions. 2.8.1 is much to old and 2.13.1 I wouldn't trust at all.

You can find the archive here: GeekGadget archives. At the same place you can also find a working libamiga.a, normal includes (ixemul-<ver>-inc) and somethere should also be the special GCC OS-inline headers (fd2inline-1.11?).

Try the 2.9.1 version. It seems new m68k-amigaos binutils and GCC archives for a MOS would be worthwhile.

Thank you for valuable informations. I've already managed (after many
long fights) ;) to compile sources for m68k. However I updated
binutils and other stuff to versions you recommend. I hope it would
let me save some problems that could appear in the future.
