Building Gearman: cannot find the flags to link with boost thread

While running ./configure things may bail out with the message “cannot find the flags to link with boost thread”. This is cause by configure not being able to find the development version of the libboost-thread libraries on the current library path. If you’ve not built libboost from source, you probably need to install the -dev version of the libboost-thread package for your distribution.

For ubuntu this package is named libboost-thread-dev (you’ll find specific versions under names such as “libboost-thread1.46-dev”. Do apt-cache search libboost-thread to see which packages are available).

For Gentoo the package is named dev-libs/boost, so just emerge that one (thanks to J/#gearman).

dpkg –configure Error for mysql-server-5.1

After starting the year by upgrading my Ubuntu desktop at work to 5.1 (and spending a couple of hours after borking my new kernel), my mysql-server had become lost in the transition.

Reinstalling the mysql-server package gave a cryptic error message:

Setting up mysql-server-5.1 (5.1.37-1ubuntu5) ...

Quite weird, yes. Trying to find anything in the mysql-logs didn’t yield anything either (both were empty), but luckily the syslog provided an answer this time. Among loads of other messages regarding mysql the answer hid from general view:

Jan  7 14:30:48 ubuntu mysqld_safe[20249]: 100107 14:30:48 [ERROR] /usr/sbin/mysqld: unknown option '--skip-bdb'
Jan  7 14:30:48 ubuntu mysqld_safe[20249]: 100107 14:30:48 [ERROR] Aborting

Taking a look at the mysql config file in /etc/mysql/my.cnf confirmed this:

#
# * BerkeleyDB
#
# Using BerkeleyDB is now discouraged as its support will cease in 5.1.12.
skip-bdb

Apparently not just the support ceased, but also the skip-bdb parameter. That seems a bit odd – I’d suggest at least keeping the parameter around for another release cycle, but anyhow:

#
# * BerkeleyDB
#
# Using BerkeleyDB is now discouraged as its support will cease in 5.1.12.
# skip-bdb

And suddenly everything went in the right general direction!
