Did you install the Xcode or the "command line tools" first?
I think there is a few things that are different.

I will try to build later.

Obviously the command line tool is already installed.
Code: [Select]
ls /Applications/Xcode.app/Contents/Developer/usr/bin/gcc
/Applications/Xcode.app/Contents/Developer/usr/bin/gcc

ls /usr/bin/gcc
/usr/bin/gcc
The gcc binary has got two locations but when I type gcc in terminal I exec the /usr/bin/gcc and it works

There was a script made to build the old dingux toolchain somewhere in the dingux development forum, I didnt find it, but i remember that was helpful at the time.

do you talk about that http://clogging.web.fc2.com/dingoo/dingux-cross.zip
what do you want to do with that ? tweak it to compile the gcw0-toolchain ?

I was just guessing. I tried right now and got the same error.
I will take a look later if I have time.

Also, look here: http://stackoverflow.com/questions/6396165/best-way-to-build-cross-toolchains-on-mac-os-x

do you talk about that http://clogging.web.fc2.com/dingoo/dingux-cross.zip

That link appears to be down, try this if you cant download https://dl.dropboxusercontent.com/u/14890209/dingux-cross-auto.zip

Yes, I would try to tweak this script to build the gcw0 toolchain. Not sure if will work.

the modification that I've already done :
-remove the lines about gcc and g++ checking in dependencies.sh
-remplace all the sed -r by sed -E in many files
-maybe oders but I don't remember, sorry...

here the remains errors :

Has anyone managed to get this to work?  I had a very quick try yesterday, but it was complaining about ncurses not being installed.  As I installed it through MacPorts maybe the headers weren't installed.  Anyway, before I invest more time in it, I'd like to know how others have fared

As I've recently acquired a Mac Mini, I decided to resurrect this thread with my new findings.

I created a fork of the GCW0 buildroot with some of my OSX patches: https://github.com/zear/buildroot/commits/osx_fixes

Changes:
* gmp: Workaround for Darwin assembler quirk.
* Remove gcc version check to allow for clang usage

In order to get past the sed problems mentioned by others above, one needs to install the GNU flavour of sed via homebrew:
Code: [Select]
brew install gnu-sed

Then it's required to add gnu-sed location to PATH, so that the terminal will see this version instead of the default BSD flavour:
Code: [Select]
export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

With those changes, I get as far as uclibc compilation, which fails at:
Code: [Select]
extra/scripts/unifdef.c:81:8: error: expected parameter declarator
size_t strlcpy(char *dst, const char *src, size_t siz);

The good thing however is that with my changes, the compilation process manages to build the compiler, before it succumbs to the issue above.

It means that one can do a simple trick of downloading the latest official x86 Linux toolchain, extracting it to /opt/gcw0-toolchain/ and then copying over the freshly built compiler, resulting in a working GCW0 cross-compiler for OSX.
I have only tested it on my own software projects, but it compiles and the produced binaries/OPKs work fine.
There are some symlink issues and I can't guarantee that every thing necessary gets compiled before the compilation process fails, however this is already something useful to many.

Because of the mentioned quirks I won't be uploading a precompiled build, but at this point I assume that the interested parties are able to compile their own version based on my github fork/branch and the above tips.

Add -D_FORTIFY_SOURCE=0 to CFLAGS to solve this issue if you're still interested to get whole build process working

Would someone be able to post a pre-built toolchain for Mac OS X based on these instructions?

The official toolchain is 32-bits only and i heard that Apple are going to discontinue 64-bits support.
So in addition to that, you will also need to compile a 64-bits toolchain on a linux distribution.

I'm afraid it won't be easily possible unless you use a linux distro or WSL.
