Hello team,
openshadinglanguage 1.12.6.2 only successfully built on x86_64 architecture but
failed on others due to the following errors:
In file included from
/builddir/build/BUILD/OpenShadingLanguage-1.12.6.2/src/liboslexec/oslexec_pvt.h:42,
from
/builddir/build/BUILD/OpenShadingLanguage-1.12.6.2/src/liboslexec/oslexec.cpp:12:
/builddir/build/BUILD/OpenShadingLanguage-1.12.6.2/src/include/OSL/mask.h:7:10:
fatal error: immintrin.h: No such file or directory
7 | #include <immintrin.h>
| ^~~~~~~~~~~~~
compilation terminated.
That "immintrin.h" is provided by both gcc and clang according to "dnf -C repoquery
--whatprovides */immintrin.h". Could someone investigate the cause and provide a patch?
See https://koji.fedoraproject.org/koji/taskinfo?taskID=92833862
Thanks in advance
Well, gcc immintrin.h is "/usr/lib/gcc/x86_64-redhat-linux/12/include/immintrin.h" (note
that "x86_64-" path).
And clang immintrin.h "/usr/lib64/clang/15.0.0/include/immintrin.h" says:
------------------------------------------
#if !defined(__i386__) && !defined(__x86_64__)
#error "This header is only meant to be used on x86 and x64 architecture"
#endif
------------------------------------------
AFAIK immintrin.h is available only on x86 / x86_64.
Then as far as I looked at src/include/OSL/mask.h, it looks like actually this
supports non-x86 architectures
(as I see #elif defined(__GNUC__) || defined(__clang__) or so),
so just try to guard the inclusion like
#if defined(__i386__) || defined(__x86_64__)
#include <immintrin.h>
#endif
and see how it goes. Maybe some additional modification is needed, but for now
I expect that
most things may go well.
Regards,
Mamoru
