Hello Jerome

I am getting the error below while running the make:

g++ -fpic -O3 -I/usr/include/tcl -c -o qwrap.o qwrap.cpp
qwrap.cpp:1:17: fatal error: tcl.h: No such file or directory
compilation terminated.
<builtin>: recipe for target 'qwrap.o' failed
make: *** [qwrap.o] Error 1

And this one while running on Tcl:

package require qwrap
couldn't load file "qwrap.so": qwrap.so: cannot open shared object file: No
such file or directory

Please let me know how to fix it or I missed some step?

Thanks and regards
Sourav
