 Posted: Sun Mar 16, 2008 5:50 am Post subject: pidgin emerge plugin |
 |
|
A friend of mine thought of it while compiling, but I did it before him, and now here is the code: The pidgin "currently compiling" plugin. Assuming you are in the portage group, it will scan /var/log/emerge.log and add a status message titled GENTOO saying which package you're currently compiling. It's not really useful, but I found the concept to be amusing.

hardcoded paths are usually a bad thing. Can't you make that a plugin configuration option?
nice idea btw

He did steal my Idea, but I must admit his C implementation is a lot better than my bash/python dbus scripting code. Good job Simon! |

I added configuration menu and fixed some issues.
I also made it available on google code, so it'll be better than copy-pasting code from a forum... even if it's gentoo forum 
You can get it from http://code.google.com/p/pidgin-gentoo/. |

A novel idea, unfortunately:
| Quote: | $ make
gcc -shared -o pidgin_gentoo.so pidgin_gentoo.c `pkg-config --cflags pidgin` `pkg-config --libs pidgin`
/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: /tmp/ccm4TWIf.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/tmp/ccm4TWIf.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [all] Error 1 |
Does that mean pidgin itself needs to be PIC, or does it mean that it won't build for x86_64?
