Hi,<br><br>Actually the xdrfile_xtc.h file did include the xdrfile.h. And I also tried to include xdrfile_xtc.h directly in my source file. The link error is still there. I really don't know what's the problem because the make test command passed. <br>

Hi,<br>
<br>
1. It seems you also need to include xdrfile.h.<br>
2. Are the library files located in the same directory with your<br>
source files when you link?<br>
