====== Installation on Linux ======

If your Linux system use deb packages,see [[Installation on Ubuntu|Installation on Ubuntu, Debian]].

On Fedora you can use ccdciel, qt5pas and libpasastro packaged with the system.

On Gentoo Linux use the overlay available here: https://github.com/jamesbates/gentoo-overlay

For other Linux system you can download rpm or tar packages from the Sourceforge [[http://sourceforge.net/projects/ccdciel/files/|download]] link.

For FITS file compression support the fpack, funpack command are required. The installation is not automatic when installing from a RPM file because of inconsistencies between Fedora and OpenSuse. Be sure you install them using the package from your distribution, it can be fpack, cfitsio, cfitsio-utils, ...

The requirement are Qt5, LibQt5Pas and [[https://github.com/pchev/libpasastro|libpasastro]].

See also the list of [[start#external_dependencies|dependencies]] to install to take full advantage of the software.

You can also compile the [[https://github.com/pchev/ccdciel|source code]] using [[http://www.lazarus-ide.org/index.php|Lazarus]].

====Specific instruction for DSLR====

To open DSLR raw files you need the library libpasraw to interface with LibRaw.\\
Unfortunately the LibRaw programming interface is not stable across LibRaw version, so libpasraw must be build specifically for your system or it not work.\\

For Ubuntu you can simply install libpasraw from this PPA:\\
https://launchpad.net/~pch/+archive/ubuntu/ppa-skychart \\

For a few other system you can find a package at:\\
https://github.com/pchev/libpasraw/releases

For other system you need to compile and install libpasraw from source after installing the libraw-dev package. See https://github.com/pchev/libpasraw/blob/master/README.md

As a last resort you can install the libraw-bin or dcraw package, but this is less performant as it need to work with temporary files.
