Simulink library linking error

Hi all,

I have the following situation:

1) I have a sfunction builder block, where I have defined a function in C, which uses external library (libxml2 to be precise). I use visual studio 2010 to compile the sfunction.

2) I am able to build the sfunction, and when I simulate/run on computer, the system responds the way I want it.

3) Trying to build the model though creates an error.

To be precise, the error I get on matlab command prompt is:

LINKING APPLICATION ... 
< lnkppc > 
(E) #A0368-D Unresolved external: 
    xmlParseDoc (first referenced in module: parse.o50)

LINKING FAILED (1) 

MAKE PROCESS ABORTED

Any help would be deeply appreciated! Thanks in advance!

In case anybody experiences the same problem as me:

What I did was to change the used library. Because I deploy he project on a platform which does not support win32 libraries, I had to include the source files of the library.

Also, in the Code Generation: I set as make command:

make_rti LNK_OPTS="-QmsA0314"

At last, do not forget to include all the libraries and any source files in: Code Generation/Custom Code/

These were enough to get my project running (although a major overhaul).

Could you please explain better all the steps you did to solve your problem? I have the same error. I am not an expert in building softwares... thank you tommaso
