[lcd4linux] adding a plugin - works only in GDB

[<Dav...@cs...>]

Hi,

I have put a quick plugin together for showing the battery state on my laptop, more than anything just to learn the format of plugins and how to add them.

I followed the Wiki instuctions to add all the extras in plugin.c, Makefile.am and plugins.m4.  The build appeared to work fine but when I tried to call the new function in interactive mode I got this...

eval> battinfo()
Evaluator: unknown function 'battinfo' in <battinfo()>
''
eval> 

After much hair-pulling and double checking, I tried running lcd4linux under GDB in interactive mode... it works

eval> battinfo()
Evaluator: wrong number of arguments in <battinfo()>
''
eval> battinfo('charging state')
'charged'
eval> 

>From a bit of googling, it seems that when things are working under GDB, but not normally, it is a threading problem. From what I have seen, in interactive mode there are no threads...  any ideas???

For the record, When running under GDB, the display will work with my plugin in non-interactive mode

Thanks in advance..
