Err ... this does not seem to be working for me. On
several different architectures that I have tried I keep
getting the same thing when I do
nm gmp-4.1.2/lib/libgmp.a | grep fft
nm gmp-4.1.2-nofft/lib/libgmp.a | grep fft
Normally I just do 'configure --disable-shared --prefix=...'.
then 'make', 'make check', and 'make install'.
To created the gmp-4.1.2-nofft version what I did was
'configure --disable-shared --disable-fft --prefix=...'.
then 'make', 'make check', and 'make install'.
What did I do wrong?
