Hi,

i try to compile openvpn-auth-ldap on CentOS 7.1 without success. issue:

yum install gcc-objc Package gcc-objc-4.8.3-9.el7.x86_64 already installed and latest version Nothing to do

[root@vpn openvpn-auth-ldap]# find / | grep objc.h /usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/objc/objc.h

am i missing anything?

Best Regards, Kristijan

Same issue here. I couldn't get openvpn-auth-ldap to compile on any recent centos. I would be great to have a list of yum dependecies to install in order to get reproduceable builds.

Hi, same problem with ArchLinux.

Hi, I have similar problem. In "config.log" I see "fatal error: objc/objc-api.h: No such file or directory". I have also found that file "objc-api.h" is no longer available in GCC (since 4.7.0) - see https://gcc.gnu.org/onlinedocs/gcc/Traditional-GNU-Objective-C-runtime-API.html - traditional vs modern API...

I do not think it has anything to do with the plugin, but rather/more-so to do with your gcc setup. At least for me (on Gentoo), I've cheated and did: # ln -sv /usr/lib64/gcc/x86_64-pc-linux-gnu/4.9.3/include/objc /usr/include/objc to get around the issue of not being able to find 'objc.h' file during config and was able to build it.
