There is actually three build issues with kvazaar on PowerPC:
The first one due to deprecated vec_lvsl() function:
strategies/altivec/picture-altivec.c: In function ‘reg_sad_altivec’:
strategies/altivec/picture-altivec.c:43:5: error: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Werror=deprecated]
perm1 = vec_lvsl(0, &data1[y * stride1]);
^~~~~
Reported upstream:
https://github.com/ultravideo/kvazaar/issues/172
The second one due to mixing AltiVec and E500 instructions:
strategies/altivec/picture-altivec.c:1:0: error: AltiVec and E500 instructions cannot coexist
Reported upstream:
https://github.com/ultravideo/kvazaar/issues/173
The last one due to enabling AltiVec on unsupported target:
strategies/altivec/picture-altivec.c:1:0: error: AltiVec not supported in this target
Reported upstream:
https://github.com/ultravideo/kvazaar/issues/174
