[Nek5000-users] -mcmodel=medium problem

[nek5000-users at lists.mcs.anl.gov]

Hello all,

When compiling tools using "gfortran", I came across an issue with 32
bit machines, it seems that "-mcmodel=medium" is not a valid option.

[root at frank tools]# ./maketools all
----------------------
Make genbox...
----------------------
make[1]: Entering directory `/root/nek5_svn/trunk/tools/genbox'
gfortran -mcmodel=medium -c   genbox.f
genbox.f:0: error: code model ‘medium’ not supported in the 32 bit mode
make[1]: *** [genbox.o] Error 1

If I remove "-mcmodel=medium", the resulting executable crashes
[root at frank tools]# pretex
-Adobe-Helvetica-Medium-R-Normal--12-120-75-75-P-67-ISO8859-1
Segmentation fault

This is also the case for for "ifort" and "icc".
ifort -mcmodel=medium -c   genbox.f
ifort: command line warning #10148: option '-mcmodel' not supported

icc -mcmodel=medium  -c -DUNDERSCORE ../../nek/byte.c
icc: command line error: invalid argument for option '-m'
make[1]: *** [byte.o] Error 1

Cheers,
Frank
