Compile/linking error about grid2grid HOT 4 CLOSED

Dear Niclas,

It seems that "libfftw3.a" does not exist in "/usr/local/lib/". You can make a soft link or you can set the installation path manually.

Can you check that "libfftw3.a" exists in "/usr/local/lib/"? If it does not exist, you need to specify the path for "libfftw3.a". You can manually set this by changing inside of CMakeLists.txt.

original :
set(FFTW3_LIB_PATH /usr/local/lib)

modification:
set(FFTW3_LIB_PATH FFTW3_LIBRARY_INSTALLATION_PATH)

or defining the path as:

cmake -H. -Bbuild -DFFTW3_LIB_PATH=FFTW3_LIBRARY_INSTALLATION_PATH

Please have a try and let us know. Have a nice day!

Dear Young-Myung,
Thank you for your quick reply!

from what I can see libfftw3.a actually exist in the specified folder:

$ ls -la /usr/local/lib/ | grep fftw3
-rw-r--r-- 1 root root 2280560 Feb 17 13:49 libfftw3.a
-rwxr-xr-x 1 root root 886 Feb 17 13:49 libfftw3.la

Do you have any other ideas on how to solve this?

Kind Regards,

Dear Niclas,

Sorry. I misunderstood the error message. You need to compile "libfftw3.a" with a flag "-fPIC".
There is an explanation in the manual on how to compile this library with this flag.

Please try compilation after recompiling the "libfftw3.a".

Have a nice day.

Thanks!
I just noticed this also. I had previously compiled fftw3 when I installed HOS-ocean and didn't need the flag then.
I have just recompiled fftw3 and made a successful compilation of grid2grid!
Now I will try it out 😀

Thank you for your assistance!
Have a nice day!
