[CLAM] building CLAM with xerces3.0.1

[David García Garzón]

Hi Ryan,

It looks like something is wrong with your setup. You might have conflicting 
xerces-c installations. Official xerces-c version in karmic is 3.0.1. The 
compiler complaints about a xerces header in the official location 
(/usr/include) but then it complaints about bad redefinition of a symbol in 
xercesc_3_1 namespace, and this means that compiler included a 3.1.x header 
before incluiding that official 3.0.x one.

So, either uninstall the xerces you installed by hand or remove the official 
libxerces-c-dev package. Sticking with the official is recommended unless clam 
were required 3.1, i don't remember right now. If 3.1 is required, the option 
is removing the official '-dev' package and defining properly PKG_CONFIG_PATH 
to 'xercesinstallprefix'/lib/pkgconfig.

A cleaner solution would be building a backport package from lucid to karmic 
by changing just the 'deb-src' sources from karmic to lucid running for 
example:
$ sudo sed -i 's/[# ]*\(deb-src.*\)karmic\(.*\)/\1lucid\2/' 
/etc/apt/sources.list

and then running:
$ sudo apt-get install debhelper libicu-dev cdbs autotools-dev
$ apt-get source -b xerces-c

Regards.
