Compile EnGrid with CGNS support
 

Hi all,

I have problems compiling Engrid with CGNS support.
I have modified the files in the src folder as follows:

engrid.pro:
I have added the line:
CONFIG += CGNS

engrid.pro.app:
I have added the line:
LIBS += -lcgns

libengrid.pro:
I have added the line:
DEFINES += CGNS_SUPPORT

I have the following error messages:

It seems that the include file is not linked well. Or there is compatibility version problem?
I am trying to install Engrid 1.4 from the source code and I have the cgns library v3.1.

Does someone have the same problem? Can you help me?
Thanks in advance.
(I hope to be clear enough..it is my first thread)
