[agtk-devel] 'Tcl_GetString' was not declared in this scope

[sub J. <dje...@go...>]

Hello,
I try to compile the tcl_wrapper of the aglib! When trying to compile the
ag.cc in the ag_wrapper/tcl directory it gives me the following error:

error: 'Tcl_GetString' was not declared in this scope

The file tcl.h is in /usr/include, but there is actually no
Tcl_GetString defined. Do I have to use a specific version tclsh? I
tried it with 8.0, 8.3 and 8.5. Gives the same error.

I simply don't know anymore where to look. Does anyne has an Idea?

Jeannette.
