Re: compiling namd gpu

Dear Sgrignani:

1 maybe you have used a compiler other than GCC. NAVIDA stated that in Linux CUDA in version < 3.0 only supports GCC. I have tried icc, and encountered the similar problems (I cannot recall that exactly). I have tried to modify the codes, although successfully complied, the programme has always thrown a "segment fault" error. Finally I delete it. So you must ensure that you use GCC only. CUDA 3.2 can support icc in 64-bit system, but I have not test that.

2 If you used GCC, in my knowledge this problem is due to the difference between gcc3 and gcc4 because of the complexity of C++ grammar. I know that a code can be compiled successfully in GCC3 but throw your error information in GCC4. Check your compiler version.

Good luck!
