Hi,
x264 FTBFS on powerpcspe[1] like this:
[...]
# Build static lib
LDFLAGS="-Wl,-z,relro" ./configure --prefix=/usr
--libdir=/usr/lib/powerpc-linux-gnuspe --enable-static --disable-cli \
|| ( tail -v -n +0 config.log config.log ; exit 1 )
No working C compiler found.
==> config.log <==
x264 configure script
Command line options: "--prefix=/usr" "--libdir=/usr/lib/powerpc-linux-gnuspe"
"--enable-static" "--disable-cli"
checking whether gcc works... no
Failed commandline was:
--------------------------------------------------
gcc conftest.c -fstack-protector --param=ssp-buffer-size=4 -Wformat
-Werror=format-security -Wall -I. -I$(SRCPATH) -maltivec -mabi=altivec
-Wl,-z,relro -lm -o conftest
conftest.c:1:0: error: AltiVec and E500 instructions cannot coexist
[...]
The attached patch fixes this by not using AltiVec on powerpcspe
since AltiVec is not present in the hardware.
Thanks,
Roland
