Qt Everywhere 5.15.8, RHEL, PostGresSQL

itsapm

Trying to build Qt Everywhere 5.15.8 with Postgres support enabled on RHEL 7.7. Can't get past the configure step.

I've installed the libpq5-devel package and its libraries and header files all seem to be in the typical default locations. What am I missing?

libpq5-devel package is installed...

$ sudo yum install libpq5-devel
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Package libpq5-devel-15.2-42.1PGDG.rhel7.x86_64 already installed and latest version
Nothing to do

Here's my configure command:

$ ./configure -prefix /opt/Qt5.15.8/5.15.8 -v -xcb -xcb-xlib -bundled-xcb-xinput -release -fontconfig -feature-freetype -sql-psql -opensource -confirm-license -silent -nomake examples -nomake tests

Configure fails with this:

ERROR: Feature 'sql-psql' was enabled, but the pre-condition 'libs.psql' failed.

Here's the configure output relating to psql

Trying source 0 (type pkgConfig) of library psql ...
+ /usr/bin/pkg-config --exists --silence-errors libpq
pkg-config did not find package.
  => source produced no result.
Trying source 1 (type psqlConfig) of library psql ...
pg_config not found.
  => source produced no result.
Trying source 2 (type psqlEnv) of library psql ...
  => source failed condition 'config.win32'.
Trying source 3 (type psqlEnv) of library psql ...
libpq-fe.h not found in [] and global paths.
  => source produced no result.

Yet...

I have libpq.* living in /usr/lib64

$ ls /usr/lib64/libpq*
/usr/lib64/libpq.so  /usr/lib64/libpq.so.5  /usr/lib64/libpq.so.5.15

I also have libpq-fe.h in /usr/include

$ ls /usr/include/libpq*
/usr/include/libpq-events.h  /usr/include/libpq-fe.h

/usr/include/libpq:
libpq-fs.h

Starting over with a fresh extraction of the 5.15.8 tarball and leaving everything else the same fixed the problem.
