The build fails with gcc version 5 or newer

[thozza]

By following the http://roseapplepi.org/index.php/how-to/build-a-minisdk-for-roseapple-pi-board/ and also other resources on the forum, the build fails with error:

It seems there are no header files for gcc 5:

$ ls /home/nneeoo/workspace/Roseapple-pi/kernel/include/linux/compiler
compiler-gcc3.h   compiler-gcc4.h   compiler-gcc.h    compiler.h        compiler-intel.h

Note that the latest gcc in Fedora is of version 6 already.

[ofree]

you can blame us for not having an up-to-date kernel (it's 3.10.x here) ..

try to apply following patch to see if it solves your problem

torvalds/linux@71458cf

[thozza]

Thank you for the clue.

It helped to resolve the compilation error, however the compilation does not pass due to other errors

try to take a look at this two commits
torvalds/linux@e16343c
torvalds/linux@aeea359

[vonfritz]

@thozza you can try this patch:
https://github.com/vonfritz/kernel/commit/e824d45043efd49607f66c89c921b07c1523bf9e
At least it builds. :)
