<br>
<br>
I tried to compile the new version 18.2 to update my old 17 one, and I <br>
encountered two errors (I use latest Intel fortran compiler from <br>
Parallel Studio):<br>
<br>
- In SRC_mixer: for main.c: undefined reference to 'MAIN__'<br>
<br>
and then multiple 'undefined reference'<br>
<br>
- In SRC_nmr: the same errors.<br>
<br>
<br>
Intel indicates that:<br>
<br>
"Resolution<br>
<br>
If you are compiling sources separately to be linked later, add the -c <br>
option to the ifort command to tell the ifort driver not to invoke the <br>
linker.<br>
<br>
If you are building a mixed-language application whose main program is <br>
not written in Fortran, use the<br>

This problem did not happen during the compilation of the older <br>
versions. Should one now use these options ?<br>

<br>
Thanks<br>
