Hello,
My system has tcl pre-installed with the headers at /usr/include/tcl8.6.
The NAMD (2.14) installation is producing the error:
..
g++ -m64 -std=c++0x
-I/home/ubuntu/charm-v6.10.2/mpi-linux-x86_64-gfortran-mpicxx/include

src/eabfTcl.C:22:10: fatal error: tcl.h: No such file or directory
#include <tcl.h>
^~~~~~~
compilation terminated.
Make.depends:360: recipe for target 'obj/eabfTcl.o' failed
make: *** [obj/eabfTcl.o] Error 1
After seeing it somewhere, I tried export TCLINCL=-I/usr/include/tcl8.6 but
didn't make any difference. I have 2 questions:
1) Which would be the recommended installation procedure when tcl is
pre-installed?
2) Does tcl have any impact on performance?
Thanks.
