[PROJ] conda + qgis + PROJ

[Even Rouault]

Javier,

this is because Conda builds have the RPATH set to "$ORIGIN/../lib"

$ readelf -d ~/miniconda3/envs/gdal_master_env/bin/gdalinfo | grep RPATH
  0x000000000000000f (RPATH)              Library rpath: [$ORIGIN/../lib]

And apparently this has priority over LD_LIBRARY_PATH

You can try something like the following

install the "chrpath" utility ("chrpath" package on Debian/Ubuntu)

cp /home/jshaw/anaconda3/envs/qgis_stable/bin/qgis 
/home/jshaw/anaconda3/envs/qgis_stable/bin/qgis_no_rpath

chrpath -d /home/jshaw/anaconda3/envs/qgis_stable/bin/qgis_no_rpath

LD_LIBRARY_PATH=/home/jshaw/work/PROJ/build/lib:/home/jshaw/anaconda3/envs/qgis_stable/lib 
/home/jshaw/anaconda3/envs/qgis_stable/bin/qgis_no_rpath

Or mess with with the content of 
/home/jshaw/anaconda3/envs/qgis_stable/lib, to symlink its libproj.so.25 
to yours
