Charm++ parallel programming system

["Casey W. Stark" <caseywstark AT gmail.com>]

Just wanted to let everyone know that it works great with gcc 4.6.0 and conv-mach.sh:

CMK_MACOSX=1

CMK_DEFS=' -D_REENTRANT '

CMK_CPP_CHARM="/usr/bin/cpp -P"

CMK_CPP_C="gcc -arch x86_64 -E"

CMK_CC="gcc -fPIC -dynamic -fno-common $CMK_DEFS "

CMK_CXX="g++ -fPIC -dynamic -fno-common $CMK_DEFS "

CMK_CXXPP="g++ -x g++ -E "

CMK_LDXX="$CMK_CXX -multiply_defined suppress $CMK_DEFS "

CMK_XIOPTS=""

CMK_QT="generic64"

CMK_LIBS="-lckqt"

CMK_RANLIB="ranlib"

...

Thanks for the help!

Best,

Casey

The particular compiler flags used on a given target platform are
defined in src/arch/<target>/conv-mach.sh.  You can edit
multicore-darwin-x86_64/conv-mach.sh to add or remove flags as needed
for your particular environment.

Ah okay. Sorry if I missed this in docs. I am using the charm-6.2 release.

They should all work the same. Where they don't, that's generally either
because you're explicitly using machine-specific features, or it's a
bug.

I can't say how much I appreciate this design after dealing with "homebrewed" parallelism in other libs.

Best,

What version of Charm is this? That flag doesn't appear any current
configuration files. In any case, you can set the compiler flags
directly by editing src/arch/multicore-darwin-x86_64/conv-mach.sh (or
the equivalent conv-mach.sh for other builds). This fix can also be
used to get rid of the -arch flag for Apple compiler releases.
