;| Create simple window using ASMx86 with Xlib |
|
||||||
|
;| --------------------------------------------- |
|
||||||
|
;| |
|
||||||
|
;| This source code demonstrates on how to create GUI using |
|
||||||
|
;| ASMx86 NASM Language with Xlib. |
|

|
;| |
|
||||||
|
;| HOW TO COMPILE |
|

|
;| ---------------- |
|
||||||
|
;| |
|
||||||
|
;| Open Terminal and use these commands: |
|
||||||
|
;| $ nasm src/main.asm -o build/main.o -felf32 -w+all -gstabs |
|
||||||
|
;| $ ld build/main.o -o bin/exe \ |
