1. Problem with gdal

   Kieran McCusker <kieran.mccusker@gmail.com> — 2020-11-12T10:16:44Z

   Hi
   
   Not sure if this is the right list as it seems like a packaging issue with
   GDAL but here goes...
   
   I am using gdal32 on fedora 33, but I've seen the problem before.
   
   I am using the github repo pramsey/pgsql-ogr-fdw to build a command line
   utility
   ogr_fdw_info which reads things like excel spreadsheets and generates
   foreign table definitions for them.
   
   The problem I am having is that when this program ends it errors on:
   free(): invalid pointer
   Aborted (core dumped)
   
   I've poked around but am struggling. I believe it is a problem with a
   destructor in proj but don't take my word for it.
   
   After using ldd on ogr_fdw_info I can make the problem disappear by doing
   the following:
   
   rm /lib64/libproj.so.15
   ln -s /usr/proj72/lib/libproj.so.19 /lib64/libproj.so.15
   
   Any help gratefully received
   
   Thanks
   
   Kieran

   Hi!
   
   This looks like an issue in the packaging that Devrim is already
   working on -- see https://redmine.postgresql.org/issues/5961
   
   Hopefully there will be a fix soon.

   RPMs are available in the same RPM repo, which actually does not have
   this issue:
   
   # ldd /usr/pgsql-13/lib/ogr_fdw.so | grep -i proj
   	libproj.so.19 => /usr/proj72/lib/libproj.so.19 (0x00007fe7df219000)
   
   (Though I know that this package needs more attention from me
   nowadays).

   As Magnus pointed out, I worked on this issue a lot in the last 2
   weeks. First of all: Please do not remove that symlink. Removing OS-
   supplied proj packages is sufficient (if you are building from source,
   please also remove proj-devel package that comes from OS. I could not
   find the exact cause why it still also links to the OS-supplied Proj,
   but until them please remove OS Proj.
