Issues when upgrading from 2.4.29 to 2.4.33

[r***@gmail.com]

Hi All

I am currently trying to upgrade my existing 2.4.29 install on CentOS Linux release 7.4.1708 (Core)

when I copy the config.nice from the existing setup and then run make I get the following error:

mod_proxy_balancer.c:25:24: fatal error: apr_escape.h: No such file or directory

The contents of the config.nice is:
#! /bin/sh
#
# Created by configure

"./configure" \
"--enable-ssl=shared" \
"--enable-rewrite=shared" \
"--enable-info" \
"--enable-proxy" \
"--enable-proxy-http" \
"--prefix=/usr/local/apache2" \
"--with-ssl=/usr/local/openssl" \
"--enable-ssl-staticlib-deps" \
"--enable-mods-static=ssl" \
"--enable-log-forensic" \
"--enable-unique-id" \
"--enable-deflate=shared" \
"$@"

Even when not using the config.nice file and doing it by the ./configure method I get the same error and cannot find any fixes for it.

I have tried removing the

"--enable-proxy" \
"--enable-proxy-http" \

which then builds but when I try and use the proxy it fails to follow the proxy correctly.

I need to get 2 servers upgraded that also have varnish installed on them, which is what the proxy is being used for.

Any help will be appreciated.

I hit the same problem which I believe was due to a previous install of apr and apr-util.

When I looked at failing compile line it was

/mydir/httpd/httpd-2.4.33/srclib/apr/libtool
--silent
--mode=compile gcc
-std=gnu99
-g
-O2
-pthread
-DLINUX
-D_REENTRANT
-D_GNU_SOURCE
-I.
...
-I/usr/include/apr-1
...

i.e. pointing at older version include files

I added symbolic links

ln -s /mydir/httpd/httpd-2.4.33/srclib/apr ~/apr/apr-1.6.3
ln -s /mydir/httpd/httpd-2.4.33/srclib/apr-util ~/apr-util/apr-util-1.6.1

so that apr and apr-util were unpacked within httpd srclib folders (as per http://httpd.apache.org/docs/2.4/install.html "Requirements) then

./configure \
...
--prefix=/usr/local/httpd-${HTTP_VERSION} \
...
--with-apr=srclib/apr \
--with-apr-util=srclib/apr-util \
...

worked
