Troubles installing Xerces - beginner

[Silvio]

Hi,

I'm quite a beginner when it comes to C++ and dev-C++ as well.
I need to use a XML library for some project, and thus decided to use Xerces.

I downloaded the sources from the web, and compiled them using Microsoft Visual C++, creating that way, a static/debug library: xerces-c_static_2D.lib.
I then copied one of the samples of code given with the sources, and tested it.

Of course, it didn't work.

I added the directory with all the source files (.hpp and .cpp) in the "include directory" list.
I also added as a parameter to the linker the path to the xerces-c_static_2D.lib file.

The software is compiling. It's when linking that I get errors (a dozen of those):
...
[Linker error] undefined reference to `_imp___ZN11xercesc_2_816XMLPlatformUtils10InitializeEPKcS2_PNS_12PanicHandlerEPNS_13MemoryManagerEb'
...

After several hours, I found that :

Saying you need to define something before computing.. I did it, but still get similar linking errors.
(I know hardly anything of processor or preprocessor.. hum)

I now get errors like this :
...
[Linker error] undefined reference to `xercesc_2_8::XMLPlatformUtils::Initialize(char const, char const, xercesc_2_8::PanicHandler, xercesc_2_8::MemoryManager, bool)'
...

I thought it was maybe not recognizing the library, but it happens that when the name of the library (given to the linker as an option) is not found, devcpp is giving an error.

Is there something obvious I don't understand ?
Do I have to add any particular directory in the "library directory" list ?

Thanks a lot.

PS : complete list of error.

Out of curiosity, why do you beleive that a library compiled by and for Visual C++ is compatible with the GCC compiler? Generally speaking, that is a very bad assumption to make.

Also, take a moment to check out the thread titled "Please Read Before Posting a Question" - in particular the section on the "Basic 3" - by excerpting the errors, and removing the information about how the cmpiler was invoked, you have thrown away a lot of information about how linking was done - which is what we need.

There is also a section in there on the compile log, including headers and linking libraries that goes over some of the basics of the process for GCC.
