Apache ./configure can't find pcre-config script

I'm trying to install Apache on Red Hat. It's a system I don't have full control over (my sysadmins have given me a directory to work in). So I've downloaded, configured, and installed APR, APR-Util, and PCRE, in addition to Apache 2.4.7.

I ran the following for APR:

./configure --prefix=/u01/app/apache/apr/
make
make install

Received the warning to remember to run

libtool --finish /usr/local/apr/lib

I changed that to

libtool --finish /u01/app/apache/apr/lib/

and it said it installed the Libraries in that location

Similarly, for APR-Util, ran:

./configure --prefix=/u01/app/apache/apr-util/ --with-apr=/u01/app/apache/apr/bin
make
make install

Told me the Libraries were installed in /u01/app/apache/apr-util//lib

Next, PCRE:

./configure --prefix=/u01/app/apache/pcre/ --with-apr=/u01/app/apache/apr/bin --with-apr-util=/u01/app/apache/apr-util/bin
make
make install

So far, no problems. Now I try to configure apache

./configure --prefix=/u01/app/apache/apache247/ --with-apr=/u01/app/apache/apr/bin --with-apr-util=/u01/app/apache/apr-util/bin --with-pcre=/u01/app/apache/pcre/bin

It finds APR and APR-Util, but of course, I get the error "Did not find pcre-config script at /u01/app/apache/pcre/bin". Why, I don't know, as the file is there at that location. What am I doing wrong? Thanks!

I solved it by specifying the full path to the pcre-config file. In other words, instead of:

--with-pcre=/u01/app/apache/pcre/bin

I did:

--with-pcre=/u01/app/apache/pcre/bin/pcre-config

Installed pcre-8.37 from pcre.org .os is rhel 7.3 and httpd 2.4.23.After installing pcre there was no need to show the path explicitly

httpd 2.4.25 still needs to specify the path to the pcre-config script, not the directory. e.g. it's --with-pcre=/home/ubuntu/pcre-8.39/pcre-config – Max – 2017-05-12T07:13:00.663

This is a shell script and thus it must begin with #!/path/to/interpreter . The most probable cause of your problem is, that this path is bad. For example it is #!/bin/perl although your perl is in /usr/bin. Check this, if it is not ok, fix it manually and retry.

Uggh, since I'm not a PERL programmer, I'll ask your indulgence. I found perl in usr/bin, not /bin. How do I "fix it manually". – Shawn – 2013-11-25T21:28:15.343

for example, I tried ./configure --prefix=/u01/app/apache/apache247/ --with-apr=/u01/app/apache/apr/bin --with-apr-util=/u01/app/apache/apr-util/bin --with-pcre=#!/usr/bin/ /u01/app/apache/pcre/bin and get -bash: !/usr/bin/: event not found – Shawn – 2013-11-25T21:41:05.277

It was only an example. It isb't probably a perl script. Is this path ok or not? From your error message I see that it is really bad. This seems to be a really dirty error message, with some exotic redhat flavour. – peterh - Reinstate Monica – 2013-11-25T21:49:47.950

the path to the pcre-config script is good. I see that file on the file system. All of the paths I'm using are good, as far as I can tell, as I see all the files on the file system. – Shawn – 2013-11-25T21:53:17.600

Nooo! I see. This --with-pcre option shouldn't begin with #! !!! That is the pcre-config script in your pcre/bin ! Please vote up my help, ask on stackoverflow what is an interpreter and what is this #! on the beginning of some script files, vote up their useful answers too, and come back. – peterh - Reinstate Monica – 2013-11-25T21:53:40.580

I guess I don't see. I started the --with-pcre option without the #! initially. I only tried it the wrong way as I was trying to figure out what to do with the #!. My original question shows how I tried it initially, and that was without the #!. Where do I use the #!? I'll gladly upvote, but I'm no closer to understanding than I was in the first place. – Shawn – 2013-11-25T22:03:25.863

This is what you should ask on stackoverflow. The answer is simple. I gladly help but I want to see your wish to learn. – peterh - Reinstate Monica – 2013-11-25T22:09:25.443

I asked this question on SO, and got sent here. There are 30000 questions about #!. You seriously expect me to go through them all? I would expect the Apache docs to mention needing an interpreter, but they don't. Sorry, but you've been much less than helpful. – Shawn – 2013-11-25T22:15:59.250

Make sure you are not using pcre2. download and compile pcre, try re-run.
