fft configure problems and make errors

[kafka-91]

I am trying to install LibXtract on my MacOSX, but it won't work.
First of all, when I configure everything, I get the following message:

Summary:

fft: no (not using fftw3, no fft functions)
simpletest example: yes
PD external: yes

Although I have installed fftw 3.3.3. I tried by adding --with-ooura, but it won't change to fft: yes. Then when I hit make, the following message appears:

Undefined symbols for architecture x86_64:
"_xtract_init_fft", referenced from:
_main in simpletest.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[3]: *** [simpletest] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Are these problems linked? Does the make not work because it cannot find the fftw3 or is it another problem?

Thanks for helping!

Hi, it sounds like you are using an old version of the code. Have you definitely pulled down all the latest changes from GitHub? LibXtract doesn't use FFTW any more. On OS X, it will automatically use Apple's Accelerate framework unless you specify --with-ooura

I downloaded the tar form https://github.com/jamiebullock/LibXtract/downloads. The folder that was unzipped is "libxtract-0.6.6"

Ah, I didn't realise that downloads page was still there—I thought GitHub had removed that feature. Version 0.6.6 is no longer supported.

Currently the best way to get the latest LibXtract, is to clone the git repository.

If you don't use git, you can just download the latest snapshot as a zip by clicking the "Download ZIP" link, which takes you to: https://github.com/jamiebullock/LibXtract/archive/master.zip

You will need autotools to compile it, which you can install using Homebrew

Ah ok, I thought they were the same. Now it worked.

Thank you very much!
