Compiling Postgis with Proj 8

[jgrocha]

autotools are not able to detect libproj with last proj version 8.

My current workaround is:

sed -i 's/pj_get_release/proj_create_from_wkt/' configure.ac

The difference between these symbols (as far as I can see) is:

$ nm --demangle -g /usr/local/lib/libproj.so.19.2.0 | grep "proj_create_from_wkt"
0000000000200260 T proj_create_from_wkt

$ nm --demangle -g /usr/local/lib/libproj.so.19.2.0 | grep "pj_get_release"
0000000000268b60 T pj_get_release()

I've compiled proj with:

cd ~/dev/PROJ
git pull
./autogen.sh
./configure
make -j8
sudo make install
sudo ldconfig

Compiling Postgis:

cd ~/dev/cpp/postgis
git pull upstream master
./autogen.sh
./configure
# or
./configure --with-projdir=/usr/local

The configure script is generated from configure.ac, see if you can patch that one.

The patch is to fix configure.ac, not the generated configure script.

$ cat configure.patch
diff --git a/configure.ac b/configure.ac
