Hi Adrian,Yes VERSION = PostgreSQL 12.1, is the only version I have. So I am novice to Linux and Postgres, where should I run this ifndef MAJORVERSION MAJORVERSION := $(basename $(VERSION)) endif $(info MAJORVERSION is $(MAJORVERSION)) and do I run as is or do I need to do something else, if so may you please assist.

> VERSION = PostgreSQL 12.1 So that is the correct version. Just to be clear there is only one version of Postgres on this machine, correct? Before you run make again, edit the Makefile so: ifndef MAJORVERSION MAJORVERSION := $(basename $(VERSION)) endif becomes: ifndef MAJORVERSION MAJORVERSION := $(basename $(VERSION)) endif $(info MAJORVERSION is $(MAJORVERSION)) When I run the above I get: aklaver@maura:~/test/cstore_fdw-1.7.0> PATH=/usr/local/pgsql/bin/:$PATH make MAJORVERSION is 12 ... and the code compiles. > *Moses Mafusire* -- Adrian Klaver adrian.kla...@aklaver.com
