[meta-java] gcc6 support breaks build for gcc < 6

[meta-java] gcc6 support breaks build for gcc < 6

[Winfried]

Commit 	33ddb28a6428b02ddcc82d1954ecf27cd426fbb5 (openjdk-8: make GCC6 
happy) adds gcc option -fno-lifetime-dse, which was added in gcc6. This 
breaks the compilation of openjdk-native on hosts where gcc4 or gcc5 is 
the default compiler.

If this is intentional, I think the README file should mention that 
meta-java requires gcc6. Better would be to add the '-fno-lifetime-dse' 
option only if gcc >= 6 is used for native compilation (if that is 
possible).

regards,
W. Dobbe

This is a non-desired side effect of the patch. Daniel, could you take
a look on this?

If you are not using default compiler then you have to take some action

add

CFLAGS_remove = " -fno-tree-dse"
CXXFLAGS_remove = " -fno-tree-dse"

via a .bbappend in your layer.

Khem, this is for /native/ so it uses hosts GCC.

oh, in such a case, there are two options, one is to have this difference
detected during configuring and then not inject it via recipe

second is to have an utility in OE to detect the compiler version.

Yep. I'll take a look in the morning.

Yes, to let meta-java compile with gcc 4.8 I added the following lines 
to a .bbappend file:

CFLAGS_remove = "-fno-lifetime-dse"
CXXFLAGS_remove = "-fno-lifetime-dse"

If that is the final solution, please add this to the README of the 
meta-java layer.

Thanks,
Winfried

Here is the .bbappend that works for me:


wdobbe@tc-linux-build2:~/yocto/peek-krogoth/sources/meta-peek/recipes-core/openjdk> 
cat openjdk-8-native_%.bbappend

CFLAGS_remove = "-fno-lifetime-dse"
CXXFLAGS_remove = "-fno-lifetime-dse"
