openal uses std::max_align_t since version 1.20.0 and
585b0cf3be
As a result, it is affected by
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56019
and the build with gcc <= 4.8 will fail on:
/home/buildroot/autobuild/instance-2/output-1/build/openal-1.20.1/common/almalloc.cpp: In function 'void* al_malloc(size_t, size_t)':
/home/buildroot/autobuild/instance-2/output-1/build/openal-1.20.1/common/almalloc.cpp:20:45: error: 'max_align_t' is not a member of 'std'
alignment = std::max(alignment, alignof(std::max_align_t));

# openal can:
|
|
# - use __atomic_*() intrinsics when available
|
|
# - otherwise use __sync_*() intrinsics when available. It needs the
|
|
# 4-byte ones on 32 bits architectures, and the 4-byte and 8-byte
|
|
# one on 64 bits architecture
|
|
# - it also provides its one implementation of atomic operations on
|
|
# x86 and x86_64, but we dont take those into account since in most
|
|
# situations __atomic_*() or __sync_*() will be available, and not
|
|
# all x86 CPUs provide the necessary assembly instructions.

OpenAL provides capabilities for playing audio in a virtual
|
|
3D environment. Distance attenuation, doppler shift, and
|
|
directional sound emitters are among the features handled by
|
|
the API.

comment "openal needs a toolchain w/ NPTL, C++, gcc >= 4.9"
