Subject: [PATCH] Fix build on PowerPC
|
|
|
|
On PowerPC-based architectures, SDL includes the altivec.h header
|
|
for SIMD intrinsics. Unfortunately, altivec.h defines some types which
|
|
conflict with C++ types like bool and std::vector. This commit adds
|
|
a wrapper for altivec.h which resolves these conflicts and allows
|
|
supertux to build and run.
|
|
|
|
Tested on a ppc64le workstation.
