[GRASS-dev] Compiling GRASS 7.4.2: Issues with FFTW3 / gmath and shared|static libraries

["Peter Löwe"]

Hello list,

I have run into a problem when compiling GRASS GIS 7.4. on a Cluster (SUSE Linux Enterprise Server-based) as a user (non-root): The issue is connected to FFTW for gmath when building GRASS with shared libraries. It disappears when using static libraries, which causes other side effects.  

Several required tools were successfully built and installed locally (gdal, geos, netcdf, sqlite and fftw).

This is the current configuration - for shared libraries


GRASS is now configured for:  x86_64-pc-linux-gnu

Make fails on this configuration as gmath breaks. Running make in the gmath director fails with this error: "relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC" 

Running make CFLAGS="-fPIC" in the gmath directory didn't help.

Strangely, changing the GRASS configure script to static libaries fixes the issue, while new issues seem to appear (CTYPES can't be created).

Any advice on the initial FFTW-related issue would be much appreciated.

best,
