Hi all,

I tried to install LANSA for the Web Apache Module on a RHEL 7.6 x64. The following are the details of my setup process (logged in as root).

Server version: Apache/2.4.6 (Red Hat Enterprise Linux)
Server built: May 28 2018 16:19:32
Python 2.7.5

[root@localhost wpi14200_lnx64]# mkdir /opt/lansaweb

[root@localhost wpi14200_lnx64]# passwd L14PGMLIB
[root@localhost wpi14200_lnx64]# groupadd LANSA

### Updating Apache configuration ###

Using system Apache configuration file "/etc/httpd/conf/httpd.conf",
added symlink "/etc/httpd/conf.d/mod_lansa.conf"
that links to "/opt/lansaweb/webserver/apache/mod_lansa.conf".

### Finished updating Apache configuration ###
### Updating /etc/sysconfig/httpd ###

Fixed LD_LIBRARY_PATH to include "/opt/lansaweb/connect".

What exactly does this error means?

Thanks in advance for your answers.

This is a known problem.
Please contact LANSA and ask for patched installer.
If you don't want to reinstall, simply copy mod_lansa.so from the patched installer package.
