[Towhee-bugs] Towhee 7.2.0 fails to build with intel studio 2017 on redhatls

[Rashid K. <ras...@tu...>]

Hi,

I am trying to build towhee 7.2.0 with a intel studio 2017 compiler. 
Towhee does not compile at all. There are two bugs:


System:

Redhat Linux Based System

gcc 6.3.0

intel studio 2017

towhee-7.2.0

First:

./configure F77='ifort' CC='icc' CXX='icpc'

your configure script tests always if the test program works with the 
gcc, no matter what compiler you provide. So you need to have a gcc 
installed to run configure, even if the Makefile which is generated 
clearly uses icc (icc    -g   -o towhee accumulateaverages.o ...). If 
you don't have a gcc installed, it can find the icc but tells you, that 
it can't compile with it and it is not working (even if it is). So far, 
so annoying. I changed the $CC Variable by hand and made sure it realy 
uses icc in the Makefile.


Second, Game Breaking Bug with some of your fortran code:

./configure F77='ifort' CC='icc' CXX='icpc'

It works with gfortran but not with ifort which is stricter. We would 
love to use the intel compiler to get a bit better performance. Btw. is 
there a reason, why you compile with -O3 instead -O2? -O3 could provide 
a speed boost with good compilers.


Kind regards
