Rebuild Debian packages from sources, actually rebuild Debian xosview from its source.

xosview (Debian binary package) has no information about my old laptop battery. The battery status shows

0%.

This bug exists on Squeeze testing, but never be fixed now. See
2010/02/04 - [computer/linux] - Debian Squeeze (testing) Installation Log (progress)

I am using FVWM as a window manager, thus the battery information is important for me and I decide to fix this bug myself. Thus, I have to build my own package for Debian.

root@coffee:# apt-get install devscripts build-essential fakeroot
root@coffee:# apt-get build-dep xosview
build-essential and fakeroot are already installed.
jhlee@coffee:$ mkdir ~/softwares/xosview_debian;
jhlee@coffee:$ cd ~/softwares/xosview_debian
apt-get source xosview
jhlee@coffee:$ cd xosview-1.8.3+debian/
jhlee@coffee:$ debuild -us -uc

After debug xosview sources, then I can see the battery status of my old laptop, and submit a bugreport to Debian with the following commands.


1) In the function bool BtryMeter::getacpi_or_sys_info, there is no /enery_*
directories in "/sys/class/power_supply" of my old laptop. All I have is
/curret_* directories. Thus, I have no battery information on xosview. I added
/charge_full_design, /charge_full, and /charge_now after /energy_full_design,
/energy_full, and /energy_now respectively in my local sources. After that, I
can see a battery status on xosview.

2) struct battery is not initialized, thus when I tried to debug them by
turning on XOSDEBUG, full capacity, remain capacity, rate, and alarm have the
same junk numbers on them.
