Stellarium libjpeg microbug in Archlinux

Minutes ago "dreaming of a telescope" I did what Galileo did 400 years ago, when, in 1609, pointed one of the first basic refractors telescopes upwars to the sky, towards Jupiter, discovering its 4 main satellites (that afterwards were called after him as "Galileian Satellites").

I took my dear old scope and I aimed it to the brightest object of tonight's sky (even from this desert Milan but photo-polluted as usual): a great Jupiter of -2 mag and something more with Ganimede at mag 4 in the top left of the ocular.

Yeah... but for knowing it was Ganimede I needed the awesome Stellarium.

I started the program but it said that without libjpeg.so.62 it wouldn't start. :-(

Then I tried to symbolic linking as "libjpeg.so.62" the libjpeg I have installed by default in Archlinux that's version 7:

$ sudo ln -s /usr/lib/libjpeg.so.7 /usr/lib/libjpeg.so.62

No way :-(

So I had to remove the just created link to clean:

$ sudo rm /usr/lib/libjpeg.so.62

.. and search with yaourt if version 6 is still available on aur.

Luckily it is! Bingo! After building and installing "libjpeg6" package from aur Stellarium worked!

... and everyone lived in happiness even if with two versions of the same library installed :-)

Goodnight and keep on hacking ;-)

bYe,
Andy
