I'm currently trying to build the cross compiler suite on OSX 10.9 but it fails when try to build binutils. :/

I'm using gcc-4.9 not clang and i've modified Bigfoot's setup-cross-sdk.sh to use gnu-tar and a remove a couple other linux-isms that made the script fall over.

It now gets as far as trying to build binutils but fails at this point

Code:

creating Makefile
if [ -n "" ] && [ ! -d pic ]; then 
	  mkdir pic; 
	else true; fi
touch stamp-picdir
echo "# !Automatically generated from ../../libiberty/functions.def"
	  "- DO NOT EDIT!" >needed2.awk
grep '^DEFVAR(' < ../../libiberty/functions.def 
	 | sed -e '/DEFVAR/s|DEFVAR.([^,]*).*|/1/ { printf "#ifndef NEED_1\n#define NEED_1\n#endif\n" }|' 
	 >>needed2.awk
grep '^DEFFUNC(' < ../../libiberty/functions.def 
	 | sed -e '/DEFFUNC/s|DEFFUNC.([^,]*).*|/1/ { printf "#ifndef NEED_1\n#define NEED_1\n#endif\n" }|' 
	 >>needed2.awk
gcc -c -m32 -O3  -I. -I../../libiberty/../include -I../../libiberty  ../../libiberty/dummy.c 2>/dev/null
make[1]: *** [dummy.o] Error 1
make: *** [all-libiberty] Error 2

Any ideas? I'm tired and annoyed so i'm off to have a smoke now.

That's where you should restart. I am pretty sure the binutils will only build with gcc 2.95.

Thanks Jaca, will give it a try later.

Building gcc 2.95.3 for OSX is even more sanity destroying. :/

I'm surprised no one seems to have built an OSX hosted cross compiler before.

Zerohero's site is down but i think he only had Linux hosted cross compilers anyway.

I know this is a little off-topic but, as gcc has matured, have the advances been x86 specific or are they also seen on other architectures?
PPC assembly ain't so bad... ;)

You can read up on the changes between version 4.4.5 as available for MorphOS and the most recent version:

http://gcc.gnu.org/gcc-4.5/changes.html
http://gcc.gnu.org/gcc-4.6/changes.html
http://gcc.gnu.org/gcc-4.7/changes.html
http://gcc.gnu.org/gcc-4.8/changes.html
http://gcc.gnu.org/gcc-4.9/changes.html
http://gcc.gnu.org/gcc-5/changes.html

There, the changes are classified into language-specific, ISA-specific and OS-specific ones.

Modifiying functions.def is only necessary for GCC 2.95.x.

The problem is not the host system, but the GCC version. 2.95.x does not like building on a 64-bit host system. Especially the ppc backend has its problems. Apparently even Apple did not build 2.95.x as a 64-bit executable. However, building as a 32-bit target using -m32 in $(CC) could work.

Just found out your archive: thanks! I couldn't build it myself.

After scratching my head trying and failing to create the cross-gcc on macOS and Linux, maybe it would be a good idea to officially release cross-dev tools ready to be used?

Nothing hurts a project more than developers not taking the time to let their community know what is going on.
