Hi Nyall,

I build both gdal master and proj 6 last week (25th), using instructions
here:
https://trac.osgeo.org/gdal/wiki/BuildingOnUnixGDAL25dev

If on a machine having another (distro) proj around you have to go
through this renaming piece if I'm correct (well, Even told me :-) )

I used:

export LD_LIBRARY_PATH=/home/richard/bin/proj/lib:$LD_LIBRARY_PATH

./configure --prefix=/home/richard/bin/gdal
--with-proj=/home/richard/bin/proj --without-libtool --with-python
--without-ogdi

Be sure (below is Even's text...) to see:

# when configuring gdal
checking for PROJ >= 6 library... checking for proj_create_from_wkt in
-lproj... no  <== this is funny, tough, because I have 6.0 ....
checking for proj_create_from_wkt in -lproj... no
checking for internal_proj_create_from_wkt in -lproj... no
checking for internal_proj_create_from_wkt in -lproj... no
checking for internal_proj_create_from_wkt in -linternalproj... yes  <== !!!

# check if libgdal.so is gelinked is with that libinternalproj:
cd /home/richard/bin/gdal/lib
export LD_LIBRARY_PATH=/home/richard/bin/proj/lib:$LD_LIBRARY_PATH
# make sure there is no /home/richard/bin/proj/lib/libproj.* files .
Only libinternalproj.so*
ldd libgdal.so | grep proj
       libinternalproj.so =>
/home/richard/bin/proj/lib/libinternalproj.so (0x00007f672346d000)

Hope this helps.

Regards,
