Hi John, Caio,

 The problem was the same with the g++ as well. I did modify the code.
I tried using wrapping the functions within extern C {} clause. But that
didn't help.
This is the error with unmodified vmd.C with g++

g++ -m32 -fno-for-scope -Wno-deprecated -Wall -O3 -DARCH_LINUX
-DVMDQUICKSURF -DVMDWITHCARBS -DVMDPOLYHEDRA -DVMDSURF -DVMDMSMS
-DVMDPBCSMOOTH -DVMDSTATICPLUGINS -I../plugins/include
-I../plugins/LINUX/molfile -I. -c vmd.C -o ../LINUX/vmd.o

Compiling vmd.C --> vmd.o ...
vmd.C: In function ‘int VMDinitialize(int*, char***)’:
vmd.C:283:52: error: ‘vmd_initialize_tcl’ was not declared in this scope

vmd.C: In function ‘void VMDshutdown()’:
vmd.C:443:20: error: ‘vmd_finalize_tcl’ was not declared in this scope

@Caio: Could the errors have to do something with tcl installation?.

Thanks.
Sandeep
