Configure error: Objective C preprocessor "/lib/cpp" fails sanity check #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I use Zimbra [1] as a groupware solution and it has an ldap server
(currently openldap 2.3.42) for authentication services. I'm trying to
compile openvpn-auth-ldap on a x64 ubuntu 8.04 server so vpn users can use
the same auth information, however configure fails with the following error:

checking how to run the Objective C preprocessor... /lib/cpp
configure: error: Objective C preprocessor "/lib/cpp" fails sanity check

All references to this error on google lead to installing build-essential
as the solution, however I have it installed and still have the error.
Also, configuring/compiling other software from source works.

What steps will reproduce the problem?
1. ./configure --with-openldap=/opt/zimbra/openldap
--with-openvpn=/usr/include/openvpn

What is the expected output? What do you see instead?
Configure should finish cleanly. However it spits out an error about the
Objective C preprocessor.

What version of the product are you using? On what operating system?
2.0.3 on x64 ubuntu 8.04.

Please provide any additional information below.
Attached are configure output and config.log.

same error came up to me too, when trying to configure this plugin on centOS 6, 
even though I had gcc already installed.
Installing gcc-objc solved the problem.
thanks
