Hi,
  Okay, I think part of the problem here is that you're trying to compile
a C++ source file with "gcc" rather than "g++". This is the most likely cause
of your problem from what I see below. If it wasn't that, I would have
said that there's something wrong with the compiler since vmd_initialize_tcl()
is declared at the top of that source file, with file-scope linkage.
Did you modify the source code? I also noticed that the line numbers
the compiler is reporting do not match the source code in CVS, they are off
by two lines.

Cheers,
  John Stone
