Hello all,

I'm compiling OF 4.1 with ICC. I have version 16 17 and 18 beta on a CentOS 7 HPC.

I tried both '-xHost' and '-fast' flags but all versions of icc gave the same error in the very beginning:

So instead of doing that, I tried all flags separately. Finally it turns out that '-ipo' flag is the reason. I have seen people compiled successfully with '-xHost' so '-ipo' shouldn't be a problem. Any idea?
