Ubuntu not running my project (samples work) *New Info
« on: May 29, 2013, 07:13:28 PM »
 Hello!

Ive recently tried setting up python/libtcod on one of my Ubuntu machines. It will run the samples.py file fine, good FPS and all. But for some reason when I set up from the first part of the tutorial, it won't run it at all. No error messages or anything, just nothing happens. I went into properties and checked the 'execute as program' box like I had to do with the samples file, but to no avail. Anyone know why this is?

My project folder looks like this;
- arial10x10.png
- FirstRL.py
- libSDL.so
- libtcod.so
- libtcodpy.py

and FirstRL.py looks like this;


Code: [Select]
import libtcodpy as libtcod
 
#actual size of the window
SCREEN_WIDTH = 80
SCREEN_HEIGHT = 50
 
LIMIT_FPS = 20  #20 frames-per-second maximum
 
 
libtcod.console_set_custom_font('arial10x10.png', libtcod.FONT_TYPE_GREYSCALE | libtcod.FONT_LAYOUT_TCOD)
 
libtcod.console_init_root(SCREEN_WIDTH, SCREEN_HEIGHT, 'FirstRL', False)
 
libtcod.sys_set_fps(LIMIT_FPS)

edit ::

I updated the source, and found some new info. If I run the script from the terminal, I get this error.

Traceback (most recent call last):

OSError: ./libtcod.so: cannot open shared object file: No such file or directory

..even though libtcod.so is in the same folder.

Another very strange thing. I copied the FirstRL.py file and the font file into the Libtcod-1.5.1 folder, and ran it from the terminal. It produced the same error. However the sample in that same folder runs fine, even if its not launched from the terminal.
