Hi,

I am trying configure php 5.4.3 from source on a ubuntu 12.04 server build using this switch --with-ldap=/usr i get this error:

configure: error: Cannot find ldap libraries in /usr/lib.

So i change to --with-ldap=/usr/include

Then i get this error:

configure: error: Cannot find ldap.h

So i find ldap.h in /usr/include

I want to create a sym link for the /include directory in the /usr/lib directory, so the config might see ldap.h.

I have tried ln -s /usr/include/ /usr/lib and ln -s /usr/include/ldap.h /usr/lib/ but i still get the same error.

Have i got my commands right?

Your syntax is right. Did you verify the perms of the file?

I learned somewhere to always create symlinks by doing what I call "linking IN". This means that I create the link while I am in the directory where link will reside.

eg--suppose I want a symlink in /home/username, and the file is /etc/stuff/thefile:

cd /home/username
ln -s /etc/stuff/thefile linktothefile

the name of the link does not have to be different--thus this is legal also:
ln -s /etc/stuff/thefile thefile

All this assumes write privileges on the directory where you are creating the link

Permissions on the directory /usr/lib: drwxr-xr-x 53 root root 4096 May 11 09:06 lib

I chmod 777 the ldap.h file.

Then ran ln -s /usr/include/ldap.h /usr/lib/ i also tried ln -s /usr/include/ldap.h .

Both create the link it appears as : lrwxrwxrwx 1 root root 19 May 11 09:00 ldap.h -> /usr/include/ldap.h

Still the same error when php is compiled.

first, you don't need "777" privileges---all the compiler needs is to read the file.

Having created the symlink, can you access the file from some random location?<<<edit--if you can't access it, then neither can the compiler>>>
