I now have a cross-compile toolchain for MacOS X. I have it installed into /opt/local, which is the directory DarwinPorts suggested for its content; I plan to eventually contribute a port. When I get a few minutes I'll post a skeleton kit like mlord has from peter with the toolchain for linux x86 that he compiled, and when I get somewhere with better network than Laura's dialup (BTW, thanks Laura!) I'll upload the toolchain. The main lodge at Hueston Woods has for-pay wireless with a decent uplink, and I paid for today, so if I get back over there tonight, maybe I can upload it now. Anyhow, I have a new gpsapp compiled with the v3 font support; I'd love to have v3 to test it with

I also have gpsapp_host compiled for MacOS, but it doesn't work yet since it's not byteswapping anything.

Here's the modified "kit" I used to build it.

Cool, I tried to compile it a while ago but didn't get anywhere with compilation problems, so I just put it on my FreeBSD box instead.

Yay! Excellent news. I'll have to give this one a try. Thanks.

http://empeg.dementia.org/distributions/

There will eventually be some sort of nice html page there, but the absolute path to the binary distribution should stay the same.

The compiled kit is about 32 megs compressed.

Now that I've finally gotten around to downloading this toolchain for darwin, I'm curious: is there any way to tie this gracefully into Xcode (or would I even want to)? Inquiring minds ...

Thanks. Have you by any chance tried to build a kernel using this toolchain? I'm getting this error:

Code:
arm-empeg-linux-gcc -D__KERNEL__ -I/Users/tonyc/dev/empeg/kernel/current/include -Wall -Wstrict-prototypes -O2  \
-fno-strict-aliasing -pipe -msoft-float -march=armv4 -mtune=strongarm110   -c -o sock.o sock.c
Assembler messages:
option `-marmv4' is deprecated: use -march=armv4
{standard input}:508: Error: Rn must not overlap other operands -- `swp r3,r2,[r3]'
make[3]: *** [sock.o] Error 1
make[2]: *** [first_rule] Error 2
make[1]: *** [_subdir_core] Error 2
make: *** [_dir_net] Error 2




No idea what's going on there. My next step would be to do build my own toolchain instead of relying on your binaries, but if you've got a quick fix, let me know.

if you build from the same source i do, you'll have the same problem. i can see where it was introduced but not why, if that patch is right, the generated code would have worked before.

i'll look some more after i get the openafs lion client finished later tonight.

can you arm-empeg-linux-gcc -D__KERNEL__ -I/Users/tonyc/dev/empeg/kernel/current/include -Wall -Wstrict-prototypes -O2 -fno-strict-aliasing -pipe -msoft-float -march=armv4 -mtune=strongarm110 -E sock.c > sock.i

and tell me what's on line 508 of sock.i?

(it's going to be an issue like this:
http://www.rockbox.org/tracker/task/7972
but the simplest way to fix it is just to patch the kernel)

Something's screwing with the line numbers, because that line (and many others) are blank. The only swp instruction I see in there is in this block:

Code:
extern const char xchg_str[];

extern __inline__ unsigned long __xchg(unsigned long x, volatile void *ptr, int size)
{
        switch (size) {
                case 1: __asm__ __volatile__ ("swpb %0, %1, [%2]" : "=r" (x) : "r" (x), "r" (ptr) : "memory");
                        break;
                case 2: abort ();
                case 4: __asm__ __volatile__ ("swp %0, %1, [%2]" : "=r" (x) : "r" (x), "r" (ptr) : "memory");
                        break;
                default: arm_invalidptr(xchg_str, size);
        }
        return x;
}


Here's the full sock.i file.

apply the attached diff to your kernel tree. i *think* that will do it. if so, i'll ask mark if he's willing to add it to v514; it's what i believe to be the barest fix.

well, basically it's just patches to deal with the tightening up of what gas enforces.

Gotcha. Now I can build kernels, but I'm getting an undefined reference to fstat error when trying to build GNU gettext:

I have. there was some fun in glibc i remember from sparclinux that did that. i'm not (network) near the toolchain; what does arm-empeg-linux-nm libc.a |grep fstat
show? you'll need the full path to libc in your install.

actually, this one should be simpler. you relocated my tree, which is fine, but you need to tweak one file. arm-empeg-linux/lib/libc.so should have the paths corrected.

i should add that to a readme.

Yeah, /opt/local is "owned" by MacPorts, so I didn't like the idea of using /opt/local/arm.

I did, however, end up symlinking /opt/local/armtools to /opt/arm, so the paths inside libc.so are legit. Shouldn't that still work?

it may be unhappy at a symlink. it's just a text file, try editing and see what happens? (fstat is defined in libc_nonshared.a)

Wonderful, now the toolchain build is failing:

Code:
hecking whether to build shared libraries... no
checking whether to build static libraries... yes
checking for objdir... .libs
creating libtool
loading cache ../config.cache
checking whether to enable maintainer-specific portions of Makefiles... no
checking for Cygwin environment... (cached) no
checking for mingw32 environment... (cached) no
checking for executable suffix... (cached) .dSYM
checking for gcc... (cached) gcc
checking whether the C compiler (gcc -g -O2 -W -Wall ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
Configure in /Users/tonyc/tmp/armtools-darwin/build-binutils/binutils-2.10.1/bfd failed, exiting.
make: *** [arm-linux-binutils] Error 1


It doesn't like gcc? Earlier in the binutils build it likes it just fine, but once it gets into bfd, it doesn't.

Update:
From the config.log in the bfd subdirectory:
Code:
configure:1850: checking for gcc
configure:1963: checking whether the C compiler (gcc -g -O2 -W -Wall ) works
configure:1979: gcc -o conftest.dSYM -g -O2 -W -Wall   conftest.c  1>&5
configure:1976: warning: return type defaults to 'int'
ld: can't open output file for writing: conftest.dSYM, errno=21
collect2: ld returned 1 exit status
configure: failed program was:

#line 1974 "configure"
#include "confdefs.h"

main(){return(0);}


errno 21 appears to be EISDIR. wtf?

you're missing a patch, the one that tells it not to assume .dSYM is an object type, for one of the config.* files.

did you use my kit for the toolchain?
