Make fails with Postgresql 11 on Ubuntu 18.04

[adamjforster]

When trying to build master (0be3a4c) with Postgresql 11 on Ubuntu 18.04 make fails because it can't find postgres_ext.h. Here are the commands that I'm using:

$ su -
# git clone https://github.com/cybertec-postgresql/pg_squeeze.git /usr/local/src/pg_squeeze
# which pg_config
/usr/bin/pg_config
# export PG_CONFIG="/usr/bin/pg_config"
# cd pg_squeeze/
# make
gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -Wno-format-truncation -g -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -fno-omit-frame-pointer -fPIC -I. -I./ -I/usr/include/postgresql/11/server -I/usr/include/postgresql/internal  -Wdate-time -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -I/usr/include/libxml2  -I/usr/include/mit-krb5  -c -o pg_squeeze.o pg_squeeze.c
In file included from pg_squeeze.h:12:0,
                 from pg_squeeze.c:10:
/usr/include/postgresql/internal/c.h:49:10: fatal error: postgres_ext.h: No such file or directory
 #include "postgres_ext.h"
          ^~~~~~~~~~~~~~~~
compilation terminated.
<builtin>: recipe for target 'pg_squeeze.o' failed

I can confirm that postgres_ext.h exists on the filesystem:

# locate postgres_ext.h
/usr/include/postgresql/postgres_ext.h

And that pg_config defines INCLUDEDIR correctly:

Can you please help?

Just an idea - it could have something to do with going "root" so I'd try with a normal user or postgres user.

[adamjforster]

@kmoppel thank you for the suggestion but I get exactly the same result with both my user and the postgres user.

Other extensions can be built? I wonder if you have the postgresql11-devel package installed.

Thank you @ahouska . It should have been obvious to me but the package name was non-standard:

$ sudo apt install postgresql-server-dev-11

Make completes without error now. Thank you both for your help.
