Adding POCO C++ Library Netbeans on Linux

Question

I am trying to use POCO C++ Library with Netbeans IDE on Ubuntu Linux 13.04. I have downloaded, build and installed the POCO C++ Library. The library can be found in the directory "/usr/local/include/Poco". I would like to know how to add the POCO C++ Library to the Netbeans IDE and be able to work with it. Please answer with details.

Thank You

Answer 1

To link an external libraries you need in general three things:

1. To add the header files as an include directory -I flag
2. To add the library path to your POCO C++ *.so files -L flag
3. To add the library name to your compiler without the lib prefix, for example with poco would be poco-Foundation and the name of your file in your system would be libpoco-Foundation.so

Now for Netbeans specific

For the header files

File -> Project Properties -> Build -> C++ Compiler -> General -> Include Directories which is step one

For the library directories

Project -> properties -> Linker -> Additional Library Directories which is step two

For the library

Project -> properties -> Linker ->Libraries -> Add option -> Other is only for the library file, which is step three.

In the case of the Poco Libraries they are usually handled like the Boost Libraries, for example

#include "Poco/AutoPtr.h"

This means the Include Directory has to be one level up from the Poco folder. For example if your Poco folder is on "/usr/local/include/Poco" then you need to add the "/usr/local/include" to your Include Directories (from step one).

As for the -L/usr/local/include/Poco This is not how it is done. This path is the path to your specific library, in the case of poco there is Foundation , XML , Net , and Util along with the test projects. You need to find the files that are named libPoco-*.so where "*" means something. This is most likely in your the directory usr/local/lib if those files are not there then they are most likely in usr/local/lib/Poco

If there are no files named libPoco-*.so you have to build your Poco libraries separately.
