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?

What optionlist are you using? There is an sl6.cfg (SL6) and a centos.cfg (CentOS 7) in SimFactory; these list the packages that you need to have installed. Maybe this would help?
