Bus Error

[shabman]

Hi, I am new to Nuklear and when I use the demo code I get a Bus Error.

The documentation isn't very clear for newcomers.

Steps to reproduce error:

#include <iostream>

#define NK_IMPLEMENTATION

#define NK_INCLUDE_DEFAULT_ALLOCATOR
#define NK_INCLUDE_STANDARD_IO

#define NK_INCLUDE_FIXED_TYPES
#define NK_INCLUDE_DEFAULT_FONT
#define NK_INCLUDE_FONT_BAKING
#define NK_BUTTON_TRIGGER_ON_RELEASE
#define NK_ZERO_COMMAND_MEMORY
#define NK_UINT_DRAW_INDEX

#include "./ui/nuklear.h"

int main() {
	 struct nk_user_font uf;
	/* init gui state */
	struct nk_context ctx;
 	nk_style_set_font(&ctx, &uf);
	nk_init_fixed(&ctx, calloc(1, 1024), 1024, &uf);

	enum {EASY, HARD};
	static int op = EASY;
	static float value = 0.6f;
	static int i =  20;

	if (nk_begin(&ctx, "Show", nk_rect(50, 50, 220, 220),
	    NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_CLOSABLE)) {
	    /* fixed widget pixel width */
	    nk_layout_row_static(&ctx, 30, 80, 1);
	    if (nk_button_label(&ctx, "button")) {
	        /* event handling */
	    }

	    /* fixed widget window ratio width */
	    nk_layout_row_dynamic(&ctx, 30, 2);
	    if (nk_option_label(&ctx, "easy", op == EASY)) op = EASY;
	    if (nk_option_label(&ctx, "hard", op == HARD)) op = HARD;

	    /* custom widget pixel width */
	    nk_layout_row_begin(&ctx, NK_STATIC, 30, 2);
	    {
	        nk_layout_row_push(&ctx, 50);
	        nk_label(&ctx, "Volume:", NK_TEXT_LEFT);
	        nk_layout_row_push(&ctx, 110);
	        nk_slider_float(&ctx, 0, &value, 1.0f, 0.1f);
	    }
	    nk_layout_row_end(&ctx);
	}
	nk_end(&ctx);
}

Output:

zsh: bus error  ./a.out

Are you using any external libraries? Are you compiling the code with any special flags? - Clerkie

Try compiling one of the SDL examples
