Unable to build 0.18 from source

[prsf1233]

I am using mod_auth_mellon in Apache on on Amazon Linux2 environment where the latest repo version is 0.14. I need 0.18 to fix the SameSite cookie issue.

I have have downloaded the source and hit two issues:

1. Amazon Linux does not have apsx2 or apsx, I have commented this section out of configure.ac and autogen.sh completes.
2. When I run make I get the following error:

make: [mod_auth_mellon.la] Error 127 (ignored)

I have checked all the required packages and development packages are installed. It appears to be complaining about header files but they look OK?

Moved on a stage, noticed I needed httpd-devel package that installs apxs. I restored the original configure.ac and ran autogen and then configure.
Running make now fails with:

/usr/bin/ld: cannot find -lltdl
collect2: error: ld returned 1 exit status
apxs:Error: Command failed with rc=65536

Resolved finally by install libtool-ltdl-devel.

Hope this helps someone else in the future.
