SDL2_Native demo

[hbiblia]

Hola

Estoy trabajando para que esto funcione nativo en SDL2, ahora mismo las demo funcionan en un 65% o menos.

Estoy utilizando SDL2_ttf y SDL2_gfxPrimitives

1. Calculator : Parece funcionar bien
2. NodeEditor : El bezier no funciona
3. Overview : Funciona en un 60%

I have trouble
on 63 line return NULL on void function and

I get

$ ./demo
Segmentation fault: 11

my makefile (please add it)

$ cat Makefile 
BIN = main
CFLAGS += -std=c99 -Wall -pedantic -O0
SRC = main.c
LIBS = -lSDL2 -lSDL2_ttf -lSDL2_gfx -lm

$(BIN): Makefile main.c nuklear_sdl.h
	rm -f $(BIN)
	$(CC) $(SRC) $(CFLAGS) -o $(BIN) $(LIBS)

clean:
	rm -f $(BIN)

[zwykl3]

When code will be working?

[zwykl3]

I get segmentation 11 when change color background and sitll

cc main.c -std=c99 -Wall -pedantic -O0 -o main -lSDL2 -lSDL2_ttf -lSDL2_gfx -lm

Great, but not working for me. Meybe correct the code?

[zwykl3]

We waiting for update
;)

[dumblob]

@zwykl3 there are few things to be addressed in #837 before I merge it. Feel free to take a look at them.

[zwykl3]

ok, what happened in native sdl version? Why still not in repo?

[dumblob]

@zwykl3 please see all my comments starting with #837 (comment) (all of them are a reason for not merging the pull request in its current state).

[hbiblia]

Vamos a resolver todo eso pues!!!

Update

@dumblob creo que ya pude corregir algunas de las cosas que menciono en #837 .

• static struct nk_sdl
• Curva de Bézier
• return NULL; error in sdl native #837 (comment)
• error in sdl native #837 (comment)
• char strcpy[len+1]; error in sdl native #837 (comment)

Encontré algunos problemas (bug)

• nk_color_picker (Segmentation fault)
  UPDATE
• nk_propertyi (Cursor se pierde) Este error esta pasando en las versiones de SDL2_GL también.
