FAQ (Frequently Asked Questions)

Win32 specific

Q: I am getting one of these:

** WARNING **: Couldn't load font "MS Sans Serif 8" falling back to "Sans 8"
** ERROR **: file shape.c line 75: assertion failed: (glyphs->num_glyphs > 0)

or any other warning or error message regarding fonts/glyphs. How do I fix this?
A: the fix is to open your C:\Program Files\Shared Files\Gtk\2.0\etc\gtk-2.0\gtkrc and to add this:

style "user-font"
{
font_name="Arial"
}
widget_class "*" style "user-font"

This forces GTK+ to use a compatible font (Arial) and reportedly fixes both the aforementioned problems, and probably others too...

Q: When I try to run the program, an error message appears on the screen saying it could not locate a dll file or that entry point is missing.
A: Be sure you installed the right GTK+ libraries. If unsure, uninstall them. Next, install CalcForgeLP again and request to download library when the installer prompts for it.

Linux specific

Q: When trying to use a parallel cable, I am getting errors like the following:

calccables-INFO: Check for parport usability:
calccables-INFO: node /dev/parport0: exists
calccables-INFO: permissions/user/group: -rw-rw---- root root
calccables-INFO: is user can r/w on device: yes
calccables-INFO: is useable: no
calcforgelp-INFO: Msg: illegal operation or argument.
Cause: the program which uses this library is buggy. Fire-up the developer!
System: Inappropriate ioctl for device (errno = 25)
calcforgelp-INFO: tilp_device_err catched error 51

Do you have any idea what causes this?
A: check that your kernel has support for parport and ppdev. Your linux kernel .config file must contains at least:

CONFIG_PARPORT=y
CONFIG_PARPORT_PC=y
CONFIG_PPDEV=y

That's all !
