Dear NAMD users,

I am trying to compile NAMD at bluegene machine following these steps:

1) Installing tcl interpreter;
2) Installing fftw library:

/configure --enable-double --enable-type-prefix --enable-static --prefix=/homebg/vyalov/fftw && make -j 32 && make install

3) Compiling charm++
4) Compiling NAMD:

(paths to tcl, fftw are written in arch/BluegeneL.tcl and arch/BluegeneL.fftw)

/config BlueGeneL-MPI-xlC
cd BlueGeneL-MPI-xlC
make

but during the compilation I get following error message:

make: *** [obj/ComputePme.o] Error 1

obviously this error arises due to the problems with precision in fftw library but I can't understand why it is happenning.
