<div dir="ltr">Yes Jeff, you're right.
<div>
<div>I found out that it was an autotools issue, I updated autotools, and now mpich builds properly for me, with icc/gcc. The idea to look into autotools came to me from this trac discussion (that was a different issue perhaps, but still):</div>

Since C is ABI compatible, just build MPICH with GCC and like with ICC apps.

<div>FWIW I compile MPICH with Intel 15/16 all the time without issues. But I'll try the latest git version to be sure. <span></span></div>

The warnings are intel's preprocessor being a bit pickier than gnu's cpp<br>
<br>
the errors, though, are indeed odd.<br>
I will eat my sock if strncmp really truly is not on your system; far more likely the strncmp test failed for some unrelated reason.<br>
<br>
Look at your src/mpl/config.log. On my system, the (successful) check for strncmp looks like this:<br>
<br>
configure:12723: checking for strncmp<br>
configure:12723: ccache gcc -o conftest -Wall -g -Wno-unused-label -fstack-usage -fPIC -ggdb3 -I /home/robl/work/soft/lustre/include conftest.c >&5<br>
conftest.c:65:6: warning: conflicting types for built-in function 'strncmp'<br>
char strncmp ();<br>
^<br>
configure:12723: $? = 0<br>
configure:12723: result: yes<br>
configure:12734: checking whether strncmp needs a declaration<br>
configure:12752: ccache gcc -c -Wall -g -Wno-unused-label -fstack-usage -fPIC -ggdb3 -I /home/robl/work/soft/lustre/include conftest.c >&5<br>

Does yours look like this?<br>
