Building GSL for Altivec

By mezza at Wed, Mar 14 2007 2:39am |

Hi,

I've tried optimising a build of GSL on a G5 using the following two approaches.

Approach 1
----------------------------
export LDFLAGS='-Wl,-framework -Wl,Accelerate'
./configure && make && make check

Approach 2
----------------------------
export CFLAGS="-fast -ftree-vectorize"
./configure --disabled-shared
make && make check

In both cases, I get tests failing. If I just do a straightforward ./configure, make etc, then all tests pass.

The machine is running OS X 10.4.8 and I'd be extremely grateful if anyone could give me some pointers.

TIA,

Merul

Hi Merul,

Could you post the specific tests that fail and any information messages (relative errors, doesn't run etc...) that the tests produce?

Thanks,

Dave
