This file is a complement to "INSTALL", which contains instructions
that are specific to Linux.


Static linking for Linux
========================

The most simple way of building Orthanc under Linux consists in
statically linking against all the third-party dependencies. In this
case, the system-wide libraries will not be used. The build tool
(CMake) will download the sources of all the required packages and
automatically compile them. This process should work on all the Linux
distributions.


To build binaries with debug information:

# cd ~/OrthancBuild
# cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Debug ~/Orthanc
# make
# make doc


To build a release version:

# cd ~/OrthancBuild
# cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Release ~/Orthanc
# make
# make doc


Note: When the "STATIC_BUILD" option is set to "ON", the build tool
will not ask you the permission to download packages from the
Internet.


Use system-wide libraries under Linux
=====================================

Under Linux, by default, Orthanc links against the shared libraries of
your system (the "STATIC_BUILD" option is set to "OFF"). This greatly
speeds up the compilation. This is also required when building
packages for Linux distributions. Because using system libraries is
the default behavior, you just have to use:

# cd ~/OrthancBuild
# cmake -DCMAKE_BUILD_TYPE=Debug ~/Orthanc
# make


However, on some Linux distributions, it is still required to download
and static link against some third-party dependencies, e.g. when the
system-wide library is not shipped or is outdated. Because of
difference in the packaging of the various Linux distribution, it is
also sometimes required to fine-tune some options.

You will find below build instructions for specific Linux
distributions. Distributions tagged by "SUPPORTED" are tested by
Sébastien Jodogne. Distributions tagged by "CONTRIBUTED" come from
Orthanc users.

Other Linux distributions?
--------------------------

Please send us your build instructions (by a mail to
s.jodogne@gmail.com)!

You can find build instructions for Orthanc up to 0.7.0 on the
following Wiki page:
https://code.google.com/p/orthanc/wiki/LinuxCompilationUpTo070

These instructions will not work as such beyond Orthanc 0.7.0, but
they might give indications.




Using ccache
============

Under Linux, you also have the opportunity to use "ccache" to
dramatically decrease the compilation time when rebuilding
Orthanc. This is especially useful for developers. To this end, you
would use:

# CC="ccache gcc" CXX="ccache g++" cmake ~/Orthanc [Other Options]
