[postgis-users] Problems creating postgis extension

[Martin Moore]

Hi,

 

On Debian Jessie 64bit, postgis 2.3, postgres 9.6 (both installed using apt-get)

 

I can’t create postgis extension 

 

 psql -d mydb -c "CREATE EXTENSION postgis;"

ERROR:  could not load library "/usr/lib/postgresql/9.6/lib/postgis-2.3.so": /usr/lib/postgresql/9.6/lib/postgis-2.3.so: undefined symbol: pj_get_spheroid_defn

 

But it is there:

 

 objdump -t -T /usr/lib/postgresql/9.6/lib/postgis-2.3.so | grep defn

0000000000000000      DF *UND* 0000000000000000              pj_get_spheroid_defn

 

It appears to have proj 4.8

 

ii  libproj0                               4.8.0-5                              amd64        Cartographic projection library

ii  proj-bin                               4.8.0-5                              amd64        Cartographic projection library (tools)

ii  proj-data                              4.8.0-5                              amd64        Cartographic projection filter and library (datum package)

 

 

I’m not a Linux guru and this has me stumped!

 

What am I missing?

 

 

Thanks,

 

Martin.
