Hello,

I recently pulled the latest charm++ in order to recompile NAMD on the Argonne Theta supercomputer - the prescribed process (from Jim Philips) now fails.

The specific build command is
$ ./build charm++ gni-crayxc-persistent-smp -j8 --no-build-shared --with-production -xMIC-AVX512

We previously had issues with icc version 17, but this happens with 17, 16, and even a beta of 18. The particular (abridged) errors that stick out are:

gmake[1]: Entering directory 'charm/gni-crayxc-persistent-smp/tmp/topomanager'
gcc: error: language MIC-AVX512 not recognized
Fatal Error by charmc in directory charm/gni-crayxc-persistent-smp/tmp
   Command gcc -D_REENTRANT -I../bin/../include -D__CHARMC__=1 -U_FORTIFY_SOURCE -D_REENTRANT -I./../include -D__CHARMC__=1 -xMIC-AVX512 -O2 -U_FORTIFY_SOURCE -c conv-cpm.c -o conv-cpm.o returned error code 1

This is a known bug in our configure/build scripts:

https://charm.cs.illinois.edu/redmine/issues/1745

It has a patch here:

https://charm.cs.illinois.edu/gerrit/#/c/3339/

 

and later

global-elfgot.C(78): error: #error directive: "Global-elfgot won't work properly under smp version: -swapglobals disabled"
  #  error "Global-elfgot won't work properly under smp version: -swapglobals disabled"

Warning: building shared library is not supported, recompile charm++ with '--build-shared'.

This won't actually fail the build, and doesn't affect NAMD at all.
