I’m trying to get started with Tcl/tk from a c++ app.
I use the following:
- This lib for implementing TclTk to c++:
http://cpptk.sourceforge.net/ - TCL 8.5.13.0 installed from http://www.activestate.com/activetcl/downloads
- Visual Studio 2010exp
I have included all the necessary header files and also linked to both boost and Tcl.
In cpptkbase.cc I have added
#define shared_ptr boost::boost::shared_ptr and
#define exception std::exception (known issues according to google)
When trying to compile i get:
1>------ Build started: Project: tcl, Configuration: Debug Win32 ------
1> tcl.cpp

Can anyone help me?
You should link agains TCL import library (it’s probably
tcl85.lib, or maybetcl85<some suffix>.libsomewhere in your ActiveState TCL folders).
