Random thoughts, How loud can I scream in void ?

Obviously, you can't rebuild only the apr_dbd_mysql.c, because /usr/include/apr-1.0/apu.h defines APU_HAVE_MYSQL to a 0 value.
And the whole apr-util library with its apr_dbd frontend has been compiled without mysql support. It would have been nice to actually be dynamic, i.e. be able to load apr_dbd_mysql.so on the fly, but it can't.

Thus, the clean solution will be to rebuild the whole aprutil package. Don't worry, it's an easy task with dpkg tools.

$ sudo apt-get install devscripts build-essential fakeroot
$ apt-get source libaprutil1
$ sudo apt-get build-dep  libaprutil1

# The apr-util-1.2.12+dfsg name is susceptible to be different according to updates.
$ cd apr-util-1.2.12+dfsg

# Change one parameter in the configure script command line
# To add a --with-mysql in the following line
$ vi debian/rules

$(CONFFLAGS) ./configure --host=$(DEB_HOST_GNU_TYPE) --build=$(DEB_BUILD_GNU_TYPE)
--enable-layout=Debian --with-apr=/usr/bin/apr-1-config --with-ldap=yes
--with-dbm=db46 --with-sqlite3 --with-pgsql=/usr  --without-gdbm
--without-sqlite2 --with-mysql --with-berkeley-db

NB: In my case, the full version number for this package was 1.2.12+dfsg-3, thus I've incremented the revision from -3 to -4 in order to update cleanly the currently installed package 1.2.12+dfsg-3

# Add a message, and change the revision number into changelog and files :
$ vi debian/changelog

apr-util (1.2.12+dfsg-4) unstable; urgency=medium

 * Add mysql support

$ vi debian/files

libaprutil1_1.2.12+dfsg-4_i386.deb libs optional
libaprutil1-dev_1.2.12+dfsg-4_i386.deb libdevel optional
libaprutil1-dbg_1.2.12+dfsg-4_i386.deb libdevel extra

NB: If unit tests failed, as it was the case for me, just comment out the C code line from the incriminated test suite. (In my case, I have commented out reslist test like this:

//    abts_run_test(suite, test_reslist, NULL);

# Launch the rebuild
$ debuild -us -uc

# Now the package should have been created in upper directory.
$ cd ..
$ sudo dpkg -i libaprutil1_1.2.12+dfsg-4_i386.deb
$ sudo dpkg -i libaprutil1-dev_1.2.12+dfsg-4_i386.deb

That's it !

Today I'll try to begin a new project, but that's not the point...

libtar and libarchive are libraries used to access the content of a tar archive (and other kind of archives for libarchive). I've used both of them to implement the comparaison of files from an archive and regular files in ftwin, here is my comparison of these libs...

After a little feature for the 0.4.0, I was looking the news @ freshmeat, and found a fabulous library to try !

As a docile linux user, I always do backup of backup of backup... and duplicate at will files here and there into my home directory ...
