Hello!

Program:

#include "dislin.h"
int main ()
{
swgopt("russian", "coding");
chacod("utf8");
winfnt("Times New Roman");
int screen_width, screen_height;
getscr (&screen_width, &screen_height);
swgwin (0, 0, screen_width, screen_height);
swgtit ("Изучение Dislin study");
int id_main = wgini ("form");
int id_basbtn = wgbas(id_main, "form");
swgwin(30, 30, 350, 50);
wgpbut(id_basbtn, "Старт Start");
wgfin ();
return 0;
}

compiled into Code blocks:
gcc.exe -Wall -std=c17 -g -c O:\MyProgramming\cDislin\cDislin.c -o obj\Debug\cDislin.o
gcc.exe -LO:\msys64\mingw64\lib -o bin\Debug\cDislin.exe obj\Debug\cDislin.o O:\MyProgramming\cDislin\dismg64.a -luser32 -lgdi32 -lopengl32
Only the terminal window appears at startup, but the form does not appear. Please help me fix the project (https://disk.yandex.ru/d/t18KU3f1nwAmlA)

Hi,

the reasen is the routine winfnt. It must be called in level 1 between disini and disfin. winfnt is not

a widget routine. Normally, winfnt should be ignored if it is not called in level 1, but it seems to be executed

and to crash the program. I have noted this as a bug.

With best regards,

Helmut

Hi, Helmut!

Thanks for the reply.

The same code in the application in the C++ application shows a form with warnings:

<<<< Warning 3: Incorrect level in chacod! ( 0)
<<<< Warning 3: Incorrect level in winfnt! ( 0)

Why is this happening?

Alex
