Charm++ parallel programming system

["Chandrasekar, Kavitha" <kchndrs2 AT illinois.edu>]

Hi Anna,

 

Regarding the first issue when doing make clean, the error can be ignored. There is a minor bug in the Makefile for hello/xarraysection example that is causing the error. For resolving the second issue, if the methods are defined in <filename>.C then you could try adding <filename>.o dependency to LIBCK_CORE in src/scripts/Makefile. This will create the object file <filename>.o from <filename>.C when building charm and link it on make.

 

Please let us know if you have any additional questions.

 

Thanks,

Kavitha

Subject: [charm] Issue after OS upgrade

 

Hello,

 

I've recently upgraded my OS dist to Ubuntu 18.04 and I've been having issues trying with Charm.

The first one happens when I run a make clean:

make[4]: Entering directory '/home/anna/charm/multicore-linux-x86_64/examples/charm++/hello/xarraySection'

Generating dependencies for hello.ci

Generating dependencies for hello.C

In file included from ../../../../include/conv-header.h:4:0,

                 from ../../../../include/converse.h:74,

                 from ../../../../include/pup.h:69,

                 from ../../../../include/ckmulticast.h:4,

                 from hello.C:2:

../../../../include/conv-config.h:77:2: error: #error "Compiler not generating 64 bit binary, please check compiler flags."

 #error "Compiler not generating 64 bit binary, please check compiler flags."

  ^~~~~

 

The second one happens when I execute a make on the lb_test directory.
I created a new Load Balancer that invokes a method from an external class, which is included in its .C file. This external class is a regular C class (.h and .C files). This is the error:

../../../../bin/../lib/libmoduleCommonLBs.a(DummyLB.o): In function `DummyLB::work(BaseLB::LDStats*)':

Thank you.
