[DragonFlyBSD - Bug #2878] [fix] CCVER problem when using clang and cpu extensions (intrinsics)

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2878 has been updated by marino.


"3. gcc/gxx can be superseded too as some ports just hardcode compiler names."

Any port that hardcodes "gcc" is wrong.  that's considered a bug, even when GCC is specified for the port.  If you find a port like that, open a PR at FreeBSD.

Ok, I'm trying to compile dri with clang37. When I setting CCVER to clang37 build stops on:

In file included from utils.c:37:
In file included from ../../../../../src/mesa/main/macros.h:36:
../../../../../src/util/rounding.h:33:10: fatal error: 'xmmintrin.h' file not found
include <xmmintrin.h>
        ^
        2 warnings and 1 error generated.

The file is present, but as per /etc/defaults/compiler.conf:

STD_INCOPT="-nostdinc -iprefix ${INCPREFIX} -iwithprefixbefore /usr/include"
DPORT_GCC_STD_INCOPTXX="-isystem /usr/local/lib/${CCVER}/include/c++ \
        -isystem /usr/local/lib/${CCVER}/include/c++/${MACHARCH}-portbld-dragonfly${MACHREL}"
DPORT_CLANG_STD_INCOPTXX="-cxx-isystem /usr/include/c++/5.0"

...

clang37_INCOPT=${STD_INCOPT}
clang37_INCOPTCXX=${DPORT_CLANG_STD_INCOPTXX}
