libxml++2.6-dev headers installed to invalid path

[kaervos]

Installing libxml++2.6-dev places the main header file at:

/usr/include/libxml++-2.6/libxml++/libxml++.h

Including this in a c++ source file as:

#include <libxml++-2.6/libxml++/libxml++.h>

then building, results in:

ubuntu@ubuntu:~/Programming/xml_playground/src$ make
g++ -DHAVE_CONFIG_H -I. -I.. -DPACKAGE_LOCALE_DIR=\""/usr/local/share/locale"\" -DPACKAGE_SRC_DIR=\""."\" -DPACKAGE_DATA_DIR=\""/usr/local/share"\" -g -O2 -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.cc

From what I can tell the libxml++-2.6 directory shouldn't exist, and the path to the main header file should instead just be:

/usr/include/libxml++/libxml++.h

Description: Ubuntu jaunty (development branch)

Package: libxml++2.6-dev
State: installed
Automatically installed: no
Version: 2.24.0-1ubuntu1
Priority: optional
Section: libdevel
Maintainer: Ubuntu Core Developers <email address hidden>
Uncompressed Size: 586k
Depends: libxml++2.6-2 (= 2.24.0-1ubuntu1), libxml2-dev (>= 2.6.1), libglibmm-2.4-dev (>= 2.4.0), pkg-config

Description: A C++ interface to the GNOME XML library (libxml2)
 libxml++ is a C++ wrapper for the libxml2 XML parser library (otherwise known as the GNOME2 XML library). It has SAX and DOM-like APIs, but does not
 attempt to conform exactly to the DOM specification because they are not aimed at C++. Its API is much simpler than the underlying libxml C API.

 This package contains development files.

But you shouldn't do that. You should use pkg-config to give you the include path, and just use
#include <libxml++/libxml++.h>

This is entirely normal for libraries which plan to have parallel-installed versions, as all libraries should.

This may help:

OOops. My n00b is showing. *blush*

I only know just enough to be dangerous. =)

I added:

`pkg-config libxml++-2.6 --cflags --libs`

to my compiler options and all is well now.

Thanks, and sorry for the false alarm.

Cheers.
