From: Tom Lane Date: Wed, 9 Jul 2025 18:21:00 +0000 (-0400) Subject: Link libpq with libdl if the platform needs that. X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4df477153a6b9339acafbf4162fd8fa3f33e89d2;p=thirdparty%2Fpostgresql.git Link libpq with libdl if the platform needs that. Since b0635bfda, libpq uses dlopen() and related functions. On some platforms these are not supplied by libc, but by a separate library libdl, in which case we need to make sure that that dependency is known to the linker. Meson seems to take care of that automatically, but the Makefile didn't cater for it.
