Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

As the compiler error says, it can't find the FFTW library. Either you didn't build that correctly, or you built it at a path that doesn't match what you told NAMD when you configured it. This is neither a Charm++ problem nor a NAMD problem. Whatever troubleshooting you did or help you got for your Tcl installation, follow the same steps here [1].

Also, since I've noticed 'Charmm++' repeatedly in your messages, please note that Charm++ (one 'm') is the parallel runtime system software that NAMD uses and which is the focus of this list, while CHARMM (two m's, no ++) is a molecular dynamics force field that NAMD implements. They have no relation to each other, and the similarity of naming is unfortunate.


[1] Again, per http://www.ks.uiuc.edu/Research/namd/bugreport.html "If you do not understand the errors generated by your compiler, queueing system, ssh, or mpiexec you should seek assistance from a local expert familiar with your setup"

Respected Phil miller sir, 

                          Thank you for you kind reply

I Built Charmm++ successfully by the following commands  as you Instruct

./build charm++ net-linux --with-production

Also  i Typed by the following command

./config Linux-g++  --charm-arch net-linux

then I have got following error when i compile by make command

/usr/bin/ld: cannot find -lsrfftw
/usr/bin/ld: cannot find -lsfftw

charmc exiting...
rm -f moduleinit7046.C moduleinit7046.o
make: *** [namd2] Error 1
 

I Humbly Request your Suggestion to solve this Problem

With Regards
