For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Integrating Tcl/Tk with C/C++

Posted by smcool89 (smcool89), 13 November 2007
I am new to tcl and to this forum also.
I saw this forum i found that i found that the error mentioned in the questions from the man are exactly the  same as mine..
I have a small program written in c interacting with tcl and i don't know how to compile and use it .. I have tried several ways mentioned at different places and have got some errors .. below is the code and the errors i got while compiling it..
the code i am compiling :

#include <stdio.h>
#include <tcl.h>

main (int argc, char *argv[]) {

       Tcl_Interp *myinterp;
       int status;

       printf ("Your Tcl Program will run ... \n");

       myinterp = Tcl_CreateInterp();
       status = Tcl_EvalFile(myinterp,argv[1]);

       printf ("Your Tcl Program has completed\n");

The error i am getting :
I tried with the following way and got some error.. can't figure it out what is this ...  
[sam@sam learning_c++]$ g++ c_tcl7.c -ltcl
/usr/bin/ld: cannot find -ltcl
collect2: ld returned 1 exit status

then i tried with this simple way and got some error and still can't find it out what is the problem behind that:
[sam@sam learning_c++]$ g++ c_tcl7.c
/tmp/ccgOFffj.o(.text+0x2d): In function `main':
: undefined reference to `Tcl_CreateInterp'
/tmp/ccgOFffj.o(.text+0x43): In function `main':
: undefined reference to `Tcl_EvalFile'
collect2: ld returned 1 exit status

Please help me....

You've not got your Tcl library and header files installed on your gcc path. Have a look at the library and include pasth options for gcc, and add extra parameters to your gcc to reflecttheir location.
