httpd-2.3.8 installation from source problem

[alfchung]

Hi,
I installed apache2 (httpd-2.3.8) from source. Here is what I did, download the source package from the apache2 website. ./configure, installed all the package it depends on, and finally, configure successfully.
make
sudo make install

I think it installed in
/usr/local/apache2

So I cd to /usr/local/apache2/bin
try
./httpd start

and it shows
./httpd: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory

ldd ./httpd
it shows
linux-gate.so.1 => (0xb7747000)
libpcre.so.0 => not found
libaprutil-1.so.0 => /usr/local/apr/lib/libaprutil-1.so.0 (0xb771b000)
libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb76f9000)
libapr-1.so.0 => /usr/local/apr/lib/libapr-1.so.0 (0xb76d1000)

libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7679000)
libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7675000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7526000)

My libpcre.so.0 is located in /usr/local/lib/libpcre.so.0, I checked that

How can I fix this problem?

Thanks!
Alfred

Install the packages libpcrecpp0 and libpcre++0 in Synaptic.

[alfchung]

$ synaptic
Segmentation fault

it doesn't work...

But I installed pcre-8.11 from source already, and it doesn't work

This question was never really answered properly. I'm having the same problem and found the correct answer. First of all, you can see all the libraries and where they are with:

cd /usr/local/apache2/bin
ldd httpd
Assuming you used the default settings for where httpd gets installed. When you do that, you should see everything's fine except:

libpcre.so.1 => not found

Now, to fix that, you have to delete the file where that library info is stored, and then rebuild the library info. These two commands will do that:

sudo rm /etc/ld.so.cache
sudo /sbin/ldconfig

To double check it worked, you can run

ldd httpd
again and see that httpd now knows where all the libraries are.

Many thanks Colin for this spot on answer!
