Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

The top-level answer to your issue is to use a precompiled binary of NAMD, as distributed by TCBG. The 64-bit Linux binaries should work perfectly well on Ubuntu 12.04. If you have trouble with that, please address those problems to the NAMD users mailing list.

To actually diagnose your trouble, we would need to *see* the error output in multicore-linux64/tmp/charmconfig.out, as the build script tells you. My best guess at the issue is that you are missing some standard development package, like libc6-dev. On a Debian or Ubuntu system on which you plan to compile software, the best resolution to this is generally to install the package 'build-essential'.

Respected Developers ,

                 I Have used the AMD 8 core processor and Ubuntu12.04 linux OS

When i install the Namd with the following commands

./build charm++ multicore-linux64 --with-production

I have go the following error

checking "whether C++ compiler works"... "ok"
checking "C++ linker as"... "g++  -D_REENTRANT -m64   -D_REENTRANT -m64     "
checking "whether linker works"... "no"
Cannot link C++ programs with g++  -D_REENTRANT -m64   -D_REENTRANT -m64  
 (check your charm++ version)
*** Please find detailed output in charmconfig.out ***
make[1]: *** [conv-autoconfig.h] Error 1
make[1]: Leaving directory `/root/NAMD_2.9_Source/charm-6.4.0/multicore-linux64/tmp'
make: *** [headers] Error 2
-------------------------------------------------
Charm++ NOT BUILT. Either cd into multicore-linux64/tmp and try
to resolve the problems yourself, 

How to revolve the problem?

Thanks in Advance
