Description
gcc version 4.1.2 20070925 (Red Hat 4.1.2-33) does not have the correct flags turned on by default for PPC/Altivec SIMD instruction use in gnuradio-core/src/lib/filter. This can be worked around by use of
./configure ... CXXFLAGS="-maltivec -O2 -g"
If you have the cell SDK installed, ppu-g++ has the correct flags on by default.
