Hi All,
Thank you for your suggestions.
Unfortunately, no way!
I tried these actions:
1. using apple-gcc4.2 for building my cross gcc compiler
2. I tried XCode (llvm)
3. I tried to add this
make CFLAGS="-g -O2 -fbracket-depth=512”
(512, 1024, 2048 … no way)!
4. I can generate my cross compiler based on the "gcc 4.8.3” without problem
(using both the apple-gcc4.2 or the XCode llvm)
So, what has changed of fundamental between the 4.8.3 and the 4.9 versions?
So, I am a bit without ideas
Cheers,
Edo
