Hi.

Any way of compiling this on a rhel8 system ? As they dropped Objective-C Compiler support, there are no gcc Objective-C packages available.

Hi,
You could add this repo:

[csi-gcc]
name=csi-gcc
baseurl=https://dl.cloudsmith.io/public/csi/gcc/rpm/el/8/$basearch
enabled=1
gpgkey=https://dl.cloudsmith.io/public/csi/gcc/cfg/gpg/gpg.7E04A007BA668C3C.key
gpgcheck=1

install gcc-objc package, which add Objective-C support for GCC. And compile :)

But, first you have to compile re2c package, which also missed on RHEL8.

I added a full solution into this Ansible role: kyl191/ansible-role-openvpn#123

I started working on getting openvpn-auth-ldap directly into EPEL 8, this also avoids the usage of (untrusted) third-party repositories.

Red Hat decided to remove the support for the Objective C language for Red
Hat Enterprise Linux 8 (and later) from the GCC packages. Unfortunately GCC
is not really modular, so /usr/bin/gcc keeps telling "Objective-C compiler
not installed on this system" until the alternative GCC /usr/bin/gobjc from
the gcc-objc RPM package from Fedora EPEL 8 is being used.

Meanwhile the openvpn-auth-ldap RPM package landed in EPEL 8 (including its build chain for those who would like to build the package on their own, however this needs #85 to be manually applied until it's merged).
