I am using Intel ifort 9.0 to compile AMBER 9 and everything seems ok. But
I've never tried Intel 8.x compilers for x86_64. Can you try "file
libcxaguard.so.5" to find out its file type?
FYI, my config.h was generated by
./configure -static -opteron -mpich ifort_x86_64 (for parallel version on
opteron w/ mpich).
Also, the "-static" can be omitted without any problem.
Hope this helps.
