[GRASS-user] compiling grass-7.8.5 on conda environment

[Laura Poggio]

Hi Vaclav,
thanks a lot!
with the patch for the makefile in the repository I managed to solve the
previous error. Now I am getting a different error apparently linked to
some library conflict (same combination of libraries works in a different
environment):

/home/user/conda3/envs/sg_py3_geo//lib//libspatialite.so.7: undefined
reference to `GEOSFrechetDistance'
/home/user/conda3/envs/sg_py3_geo//lib//libspatialite.so.7: undefined
reference to `GEOSFrechetDistance_r'
/home/user/conda3/envs/sg_py3_geo//lib//libspatialite.so.7: undefined
reference to `GEOSFrechetDistanceDensify'
/home/user/conda3/envs/sg_py3_geo//lib//libgdal.so.27: undefined reference
to `GEOSMakeValid_r'
/home/user/conda3/envs/sg_py3_geo//lib//libspatialite.so.7: undefined
reference to `GEOSFrechetDistanceDensify_r'

Tomorrow I will try again with a clean conda environment implementing all
of your scripts.
Thanks a lot!

Laura
