Charm++ parallel programming system

["White, Samuel T" <white67 AT illinois.edu>]

Hi Rob,

The EveryLB module is only built when you specify the "LIBS" target to the build script rather than the "charm++" target (./build LIBS mpi-linux-x86_64). We can fix our make test to not rely on EveryLB being built by default.

Thanks,
Sam White

Subject: [charm] Problem building tests in charm++ 6.7.1

I extracted the 6.7.1 archive, executed this build statement:

./build charm++ mpi-linux-x86_64 mpicxx smp --with-production --build-shared --basedir=$MPI_ROOT

That appeared to build without issue.

I then changed to the examples directory and executed "make".  That appeared to build without issue.

I then changed to the tests directory and executed "make".  It failed at this point:

../../../../bin/charmc -optimize -production  -language charm++ -o lb_test lb_test.o Topo.o -module CommonLBs

../../../../bin/charmc -optimize -production  -language charm++ -o lb_test.every lb_test.o Topo.o -module EveryLB

I went back to the output of the build command, and found this for EveryLB:

../bin/charmc -intrinsic -optimize -production  -build-shared EveryLB.ci && touch EveryLB.ci.stamp

After softlinking the headers, there was a section where dynamic libs were being built:

Performing '/usr/bin/gmake charm++ OPTS=-optimize -production QUIET=' in mpi-linux-x86_64-smp-mpicxx/tmp

../bin/charmc  -optimize -production  -build-shared -I.   -c -o DummyLB.o DummyLB.C

../bin/charmc  -optimize -production  -build-shared -o ../lib/libmoduleDummyLB.a DummyLB.o

../bin/charmc  -optimize -production  -build-shared -o ../lib/libmoduleGreedyLB.a GreedyLB.o 

Warning: creating ../lib_so/libmoduleGreedyLB.so ​

but EveryLB does not appear in this output.

Is there some additional parameter I need to add to "make" to make the tests build correctly?

Also, am I building the examples and tests correctly?  i could not find any parameter to add to the build statement to make it build examples and tests along with everything else.

Thanks.
