    Hi, All:

    Because I am not Root, so I setup IT++ at a local directory. The compilation is fine but I got the following errors during creating the output file. I have no idea on the error messages. Could you please help me to resolve the issue? Thank you so much.

    Try to add -lgomp to your gcc flags. Please consult following thread regarding the unresolved symbols in xerbla (it seems you are using incompatible versions of gnu fortran and acml)

    You could use itpp-config script for passing command line arguments to gcc. IT++ 4.3.1 generates and installs this script
