having an issue to mlx_init, it returns 0

[raymond0517]

Hi, not sure where went wrong, I can't get display!!, please help, man thanks.

echo $DISPLAY
8:8:8:8:0.0

C:\WINDOWS\system32>wsl --status
Default Distribution: Ubuntu
Default Version: 2

The following code having mlx_init() returns 0, which means can't get display
#include <mlx.h>
#include <stdio.h>
typedef struct s_data {
void *img;
char *addr;
int bits_per_pixel;
int line_length;
int endian;
} t_data;

void my_mlx_pixel_put(t_data *data, int x, int y, int color)
{
char *dst;

    dst = data->addr + (y * data->line_length + x * (data->bits_per_pixel / 8));
    *(unsigned int*)dst = color;

}

int main(void)
{
void *mlx;
// void *mlx_win;
t_data img;
printf("cp1");
fflush(stdout);
mlx = mlx_init();
