Looking through documentation.conf and existing poky sources, I believe this test is correct. HOST/TARGET are the same in this case. The comment is a bit confusing however. I believe the comment should read:

# liburcu doesn't build for MIPS
COMPATIBLE_HOST = '(x86_64.*|i.86.*|arm.*|powerpc.*)-linux'

The key difference being "for" instead of "on". The rest of the comment is redundant with the assignment itself. This applies to all 4 patches.

Thanks,

Please include the reason for the COMPATIBLE_HOST test in all recipes.

OK.

Looking through documentation.conf and existing poky sources, I believe this test is correct. HOST/TARGET are the same in this case. The comment is a bit confusing however. I believe the comment should read:

Quoted 6 lines

# liburcu doesn't build for MIPS
COMPATIBLE_HOST = '(x86_64.*|i.86.*|arm.*|powerpc.*)-linux'
The key difference being "for" instead of "on". The rest of the comment is redundant with the assignment itself. This applies to all 4 patches.

OK, got it, V3 soon.
