Description ncahill_alt 2016-09-27 15:44:19 UTC
sys-fs/squashfs-tools fails to build with gcc-5.  The fault seems to be that gcc now defaults to -std=gnu11 rather than C99.  I've found a patch online, here it is slightly modified but it worked for me just fine.  To use it, run patch -p1 < squashfs-tools-gcc5.patch.

Original patch was here:

Neil Cahill

Comment 1 Adrian 2016-12-07 00:25:43 UTC
This bug occurs on my machine as well, and is resolved by the patch provided by Neil Cahill.

As mentioned in the link to the original patch, this only occurs when compiling with -O0, so setting eg. -O2 is a possible work around while the patch is being assessed.
