FFTW 3.1.3
First follow setup directions here. For some reason “–enable-shared” must be before prefix.
- Configure: $ ./configure -–enable-shared -–prefix=$EXTDIR
- Make: $ make -j 3
- Test: $ make check
- Install: $ make install
“make check” should output a message to the effect of saying all was good.
Below is a block quoted version of the commands needed:
./configure -–enable-shared -–prefix=$EXTDIR
make -j2
make check
make install
