[Users] Is "sudo ln -sf libmpichcxx.so libmpicxx.so" safe?

Dear all,

I am using Scientific Linux 7, and I get an error when I try to building the toolkit:

" /usr/bin/ld: cannot find -lmpicxx /usr/bin/ld: cannot find -lmpi "

It seems that the library libmpi is missed, but I have installed mpich and mpich-devel and mpich-autoload. And there exist "libmpichcxx.so" and "libmpich.so".

So I try to run this command "sudo ln -sf libmpichcxx.so libmpicxx.so" and "sudo ln -sf libmpich.so libmpi.so" and the build has done.

I want to know if this operation safe? Will it have some harmful effect on the result of EinsteinToolkit?
