Installing RApache in Ubuntu 16.04 Apache/2.4.18 (Ubuntu): I get some errors about rapache HOT 4 CLOSED

Hi Roberto,

Looks like ubuntu no longer breaks out the dev files for the prefork mpm.
Plus the prefork mpm comes installed by default (but not configured) with
the apache2 package.

These are the packages I installed to get rapache to compile: apache2
libapreq2-dev apache2-dev

Also, Jeroen put a nice changelog entry in debian/changelog that explains
this:

libapache2-mod-r-base (1.2.8-xenial0) xenial0; urgency=low

• Remove apache2-mpm-prefork dependency (prefork is now included
  with apache2-dev / apache2-bin)

I get an error message:

debuild -us -uc

I get the message:

libapache2-mod-r-base_1.2.8.orig.tar.xz or rapache.orig) continue anyway?
(y/n)

I decide for yes but it does not work, I get:

Is there anybody who can help me please?

Wow I was not aware of that. We should update the manual that folks can now install rapache straight from debian/ubuntu :D

from rapache.

Hi Jeffrey,

What I finally did was:

sudo apt-get update
sudo apt-get install libapreq2-dev apache2-dev
sudo apt-get install libapache2-mod-r-base
sudo git clone https://github.com/jeffreyhorner/rapache
cd rapache
sudo debuild -us -uc
cd ..
sudo dpkg -i libapache2-mod-r-base*.deb

I get some warnings and errors but it seems to work...

Thanks for your help folks!!
Roberto
