sorry for delay but ran some tests on older version pg gem - still fails
With what error message?
What Ruby gem?
it fails on building the config file with simply missing libpq-fe.h,
cannot find libpq-fe.h
Well it is there:
rpm -qlp postgresql10-devel-10.1-1PGDG.f27.x86_64.rpm | grep libpq-fe.h
warning: postgresql10-devel-10.1-1PGDG.f27.x86_64.rpm: Header V4
DSA/SHA1 Signature, key ID 442df0f8: NOKEY
/usr/pgsql-10/include/libpq-fe.h
I suspect it is a problem with using the pgdg repository and that
postgresql get "10" added to them ie postgresql10-devel and maybe the
gem code does not recognize that. Since vers 10 is not breaking it
does not make sense (i guess fedora) to rename vers 10 with the "10"
- maybe they just love the python 2 / 3 fiasco and want to extend it
to postgresql.
Previous versions used version numbering also:
https://yum.postgresql.org/9.6/fedora/fedora-26-x86_64/
postgresql96-devel-9.6.6-1PGDG.f26.x86_64.rpm
My guess it that the config script for the gem is not taking into
account that Postgres changed from a three part versioning system
X.Y.z to a two part system X.y(where lower case is minor version) from
9.6.0 to 10.1.
could be, cannot find the config file in the repository - specifies to
use a pg-config file to build the gem but no trace of such a config file
It is not looking for a file named pg-config, it is looking for a
program named pg_config.
See:
https://deveiate.org/code/pg/
gem install pg -- --with-pg-config=<path to pg_config>
Try something like below to verify pg_config is installed(I'm sure it is):
aklaver@tito:~> pg_config
BINDIR = /usr/local/pgsql96/bin
DOCDIR = /usr/local/pgsql96/share/doc
HTMLDIR = /usr/local/pgsql96/share/doc
...
LIBS = -lpgcommon -lpgport -lxml2 -lssl -lcrypto -lz -lreadline -lrt
-lcrypt -ldl -lm
VERSION = PostgreSQL 9.6.6
*IMPORTANT* If you have more then one instance of Postgres installed you
will have more then one pg_config binary, so it is important that you
point the gem install at the correct one.
thks anyway for your help. had emailed the pg gem leads but no response
and github issues are blocked (duh) - can't depend on this -will just
make a faster transition to Crystal - the pg shard in Crystal loaded
okay on Fedora with the 10.1
Are you talking about this?:

The above is a Git mirror of the 'real' repo, which is on BitBucket:

You will find an issues page there.

What was the error message returned when you tried to install
originally?
it is not in fedora 27 postgresql10-devel. If install
postgresql-devel (9.6) the gem installs without problem but afraid
this will interfere with 10.1 How can we install the necessary
libpq-fe.h ? thks
