I'm trying to build freeradius from the git version 4.0.0 on Almalinux9, but having problems with failures building the included dlopen.c. Building under the OpenPKG package management system. # uname -a Linux almadev9.mi.celestial.com 5.14.0-70.13.1.el9_0.x86_64 #1 SMP PREEMPT Tue May 17 15:53:11 EDT 2022 x86_64 x86_64 x86_64 GNU/Linux gcc-11.2.0 binutils-2.38 automake-1.16.5 autoconf-2.71 libtool-2.4.6 The compile is failing with __GLIBC_USE and __GNUC_PREREQ errors. The configure script finds the system's -ldl, but I haven't been able to figure out how to use that instead of the included dlopen. I've had similar results trying to build on the latest versions of 64-bit Raspberry Pi Linux.
