including tk.h and tcl.h in c program

Question

hi, i am working on an ubuntu system. My aim is to basically make an IDE in C language using GUI tools from TCL/TK. I installed tcl 8.4, tk8.4, tcl8.4-dev, tk8.4-dev and have the tk.h and tcl.h headers file in my system. But, when I am running a basic hello world program it's showing a hell lot of errors.

#include "tk.h"
#include "stdio.h"
void hello() {
     puts("Hello C++/Tk!");
}
int main(int, char *argv[])
{     init(argv[0]);
     button(".b") -text("Say Hello") -command(hello);
     pack(".b") -padx(20) -pady(6);
}

Some of the errors are

tkDecls.h:644: error: expected declaration specifiers before ‘EXTERN’

/usr/include/libio.h:488: error: expected ‘)’ before ‘*’ token

In file included from tk.h:1559,
                 from new1.c:1:
tkDecls.h:1196: error: storage class specified for parameter ‘TkStubs’
tkDecls.h:1201: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

/usr/include/stdio.h:145: error: storage class specified for parameter ‘stdin’

tk.h:1273: error: declaration for parameter ‘Tk_PhotoHandle’ but no such parameter

Can anyone please tell me how can I rectify these errors? Please help...

Answer 1

but... shouldn't you use <> for systemwide include?! and button("..") -text("...") .. isn't good C grammar, unless tk.h gives powerful macros button and -text (which is problematic i.e. not possible), and I suspect it is not so (in fact it is not so)... You could be interested in this, and also a reading to this and digging around is worth; and also (more interesting for you maybe), read e.g. this
