Build OpenLDAP 2.3.x from sources on Ubuntu

It happened so that I needed to build a particular version of OpenLDAP on Ubuntu and use that instead of the one in Ubuntu’s repository. Here is a quick guide as to how it worked for me:

1. Get BDB 4.3 sources from Oracle’s site(link)

2. Compile BDB and install it:

tar –xvzf db-4.3.29.tar.gz
cd db-4.3.29/build_unix
./configure --prefix=/usr/local/bdb43
sudo make install

3. Get OpenLDAP source(ftp link)
4. Compile and install it:

tar xzvf openldap-2.3.35.tgz
cd openldap
export CPPFLAGS="-I/usr/local/bdb43/include -D_GNU_SOURCE" 
export LDFLAGS="-L/usr/local/lib -L/usr/local/bdb43/lib -R/usr/local/bdb43lib" 
export LD_LIBRARY_PATH="/usr/local/bdb43/lib"
./configure --prefix=/usr/local/openldap

If you’re installing version 2.3.x or anything before 2.4.15 you will need to manually patch OpenLDAP otherwise you’ll get this error:
../../include/ldap_pvt_thread.h:64: error: missing binary operator before token “(“
Patch file is available in this bug report
Or already patched file for OpenLDAP version 2.3.35 you can download here

If you’re installing anything >= 2.4.15, you can skip the patch.

Once patch is applied just run:

make depend
make test  #this will take a while to run 
make install

Common Errors:
configure: error: Berkeley DB version mismatch
Solution: Most likely you didn’t LDFLAGS and LD_LIBRARY_PATH as noted above

getpeereid.c:52: error: storage size of ‘peercred’ isn’t known
You need to include -D_GNU_SOURCE flag, to avoid incompatibility with glibc

../../include/ldap_pvt_thread.h:64: error: missing binary operator before token “(“
Solution: Apply patch as noted above

error while loading shared libraries: cannot open shared object file: No such file or directory
Solution: Add libdb-4.3 to shared libs cache:

sudo echo "/usr/local/bdb43/lib" > /etc/
lddconfig -v

Gnome Do, Docky, upgrade to Ubuntu 10.10 and an odd case of /var/lib/dpkg/

So I finally upgraded to 10.10, a bit behind the curve but whatever. For the most part it went surprisingly swimmingly. I only had 2 issues :)

First one – gnome-do docky theme was gone. And apprently it’s gone for good and now it is a separate project. Fix is as simple as:

sudo apt-get install docky

Fixed that right away.

Second issue was a bit more annoying. Problem was with updating linux-firmware package. For some reason dpkg was throwing and error saying that ‘/var/lib/dpkg/ Is a directory‘. After messing around fix for that was basically this:

sudo bash
cd /var/lib/dpkg/info
rm -rf linux-firwmare*
apt-get upgrade

What happen is /var/lib/dpkg/info/linux-firmware.md5sums got corrupted and instead of being a file it became a directory point to postfix’s folder(in my case). I had some hard drive issues few weeks ago, so probably fsck did this… oh well, can’t blame it :)

Installing Mercurial 1.5, 1.6 or 1.7 on Ubuntu Lucid Lynx 10.04

Lycid Lynx’ repository by default set to install Mercurial 1.4.x, which is great, but as of today that’s already 3 major releases behind :( To get yourself on the latest and greatest version of Mercurial there are 2 options: build from the source or just add mercurial-releases repository like this:

sudo add-apt-repository ppa:mercurial-ppa/releases
sudo apt-get update
sudo apt-get install mercurial

Make sure it did the right thing:

$ hg --version
Mercurial Distributed SCM (version 1.6)

Another thing that will go nicely with Mercurial 1.6.x or 1.7.x is up-to-date TortoiseHg. To install TortoiseHg on Ubuntu 10.04 you’ll need to run the following:

sudo add-apt-repository ppa:tortoisehg-ppa/releases
sudo apt-get update
sudo apt-get install tortoisehg-nautilus

XDebug doesn’t show local variables in Komodo, NetBeans or Eclipse PDT

Lovely surprise that came sometime after upgrading Lucid Lynx(and thus to PHP 5.3.2) – Xdebug doesn’t show local variables. Fortunately that’s a known issue that is fixed in Xdebug 2.1.0RC, but since it’s not released, it is not yet in Ubuntu’s repository. This should be pretty easy to fix though :) let’s try this:

sudo apt-get install php5-dev php-pear

That’ll get us ready for manual xdebug building. Then we need to get the sources. Gotta tell you, Xdebug guys are pretty awesome – they put together this nice little tool that helps you find and build the right version:

It requires output of phpinfo() or in ‘php -i’ command and based on that gives you set by step instructions.

For standard Lucid Lynx install it boils down to the following commands:

tar -xvzf xdebug-2.1.0RC1.tgz
cd xdebug-2.1.0RC1
sudo cp modules/ /usr/lib/php5/20090626
sudo /etc/init.d/apache2 restart

Before restarting the server though(last command) you may want to double check the the following line exists in either /etc/php5/apache2/php.ini or in /etc/php5/apache2/conf.d/xdebug.ini

zend_extension = /usr/lib/php5/20090626/
