I have a ploblem!

How integrate Tcl/Tk and C++. For example - how use Tk interface with C++ console applications.

Code:

/////////////////////////// #include <iostream.h> main() { cout << "Helo" << '\n'; return 0; } ///////////////////////////

For example how bind string 'Helo' with Tk field "Entry".

Have a look at "Tcl and the Yk toolkit" by John Ousterhout - the author of the Tcl language ... http://www.wellho.net/book/0-201-63337-X.html;  there's about 100 pages there on the integration of Tcl and Tk into a C application, and it should work just as well for C++.  Tcl was designed as a library to integrate a scripting language into C ... it's not that hard to do.


Thanks!

But I need simple example of this integrate.
It can be not only for C++. If anybody can wrote anything for C please do it..



Here's a simple example of extending Tcl by building an application with an interpretter in C, and extending the application with a command written in C.

Code:

/* Well House Consultant - building TCL into a C application */ /* Extended Tcl - an extra command written in "C" */ #include <stdio.h> #include <tcl.h> int equal(ClientData notneededhere, Tcl_Interp *ipointer,    int eq_argc, char *eq_argv[]) {    /* Should check argument count! */    if (strcmp(eq_argv[1],eq_argv[2]) == 0) {    ipointer->result = "1";    } else {    ipointer->result = "0";    }    return TCL_OK; } main (int argc, char *argv[]) {    Tcl_Interp *myinterp;    int status;    printf ("Your Tcl Program will run ... \n");    myinterp = Tcl_CreateInterp();    Tcl_CreateCommand(myinterp,"same",equal,    (ClientData) NULL,    (Tcl_CmdDeleteProc *) NULL);    status = Tcl_EvalFile(myinterp,argv[1]);    printf ("Your Tcl Program has completed\n"); }

It's the start of what you need; to bind your text field to a variable in C, you need to learn about the various variable types and data transfers between C and Tcl, and (as per previous post) the best way to find this is from John Ousterhout's book.  Please do post a follow up if you have any questions that relate to the examples in the book - I think there's only the one edition, so if you refer me by page number I'll be able to get straight to the point.

I have a ploblem.
My gcc compiler give :

[root@localhost CPP_igor]# gcc tcl.c
/tmp/ccYRRwKN.o: In function `main':
/tmp/ccYRRwKN.o(.text+0x5b): undefined reference to `Tcl_CreateInterp'
/tmp/ccYRRwKN.o(.text+0x79): undefined reference to `Tcl_CreateCommand'
/tmp/ccYRRwKN.o(.text+0x8f): undefined reference to `Tcl_EvalFile'
collect2: ld returned 1 exit status
[root@localhost CPP_igor]#

Please help to compile this source...


Do you have the Tcl header file (tcl.h) loaded and in the correct path for gcc?

Yes I have it.
And I think tcl.h currently included into source...

OK ... are you specifying any command line options to your compile to load in the tcl library (such as -ltcl)?

I add command line options and source is compiled correctly.
But now out is "Segmentation fault"...

 

I'm guessing that you're running the program without any command line parameters.   This example is a tiny piece of code that's written to be easy to follow and understand, and it does not do any error checking.   Have a look at the code and work out what you need  

Thanks I try.

But i still don't understand how it working.
Anyway thanks a lot!

hello

sorry for my poor english, like you can see i'm not native speaker


i was looking at a topic with you and triclosan
i have some problems with integration of tcl/tk with c too

first i use code::blocks ide with mingw32 under windows
i'm medium programmer with c but beginner with code::blocks, and with gcc...(i never make a make manualy... )
i try to use the common dialogues of tcl/tk in a c program
i just found .lib
but it seems that mingw32 need .a library (but not always...)
do i need .lib or .a ?
i try to use reimp.exe, that reimplement the .lib like a .a but it seems odd...
the weight is not the same (  192 ko for tcl84.lib vs
                                              664 ko for libtcl84.a     may be a problem)

thus where can i found precompiled .a for windows
i try to found on web, to the site of sourcenet, but i dont find...
i would to compile tcl/tk thus i download source files
but it was "a little" more complicated that i thought...^^
too much for me indeed, i don't know where is the beginning^^ it is a very big projet...
thus i'm not sure of my reimplementation by reimp.exe


and once i have them, how to install, and how to configure ? (path that i have to give to the linker, compilator option, ...)(i gave every things that i can, but it seems that it doesn't make links...i certainly make a stupid thing but where)
it say
Code:

mingw32-gcc.exe: -ltk: linker input file unused because linking not done mingw32-gcc.exe: -ltcl: linker input file unused because linking not done

it's very difficult to found information on tcl/tk with c on the web (and under windows and code::blocks !!!)

i compiled the code that you gave to triclosan
with adding this little code:
Code:

if (Tcl_Init(myinterp)!=TCL_OK) {    fprintf(stderr,"Tcl_Init failed: %s\n",myinterp->result); }

the console program said:

Can't find usable init.tcl in the following directories:
this probably means that Tcl wasn't installed properly


i try to reinstall tcl/tk ( activetcl pack )
but the problem is still the same


i hope that i was enought clear, sorry if my questions are so beginner level, but i don't found answers for my questions anywhere
thanks a lot




Hello
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..

[sam@sam learning_c++_tcl]$ 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


Then i compiled it in the following way :

[sam@sam learning_c++]$ g++ c_tcl7.c -ltcl
/usr/bin/ld: cannot find -ltcl
collect2: ld returned 1 exit status

Please guide me how to remove the error and run the code perfectly.
thanks

Hello.  See answer in other thread.   (There's no need to ask a question twice ...)
