Building PROJ with modern linux #112

Closed snowman2 closed 3 years ago

PROJ 8.1 requires pread64 ref. The current builds for conda-forge don't seem to work.

There are 2 possible reasons:

conda-forge is building with a version of of linux before pread64
the sqlite package isn't built with the needed CFLAGS="-DHAVE_PREAD64 -DHAVE_PWRITE64" ref

I'm not sure. How can we check this? Maybe @isuruf can help but he is very busy at the moment.

@ocefpaf, this build seems to work ref. One way to check would be to merge that in and build PROJ with this sqlite and see if it works.

Problem resolved with the updated sqlite build:

# Name                    Version                   Build  Channel
proj                      8.1.1                h277dcde_0    conda-forge
sqlite                    3.36.0               h9cd32fc_1    conda-forge

Apparently the re-build of PROJ wasn't necessary.
