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


Static linking for GNU/Linux
============================

The most simple way of building Orthanc under GNU/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 any GNU/Linux distribution, provided that a
C/C++ compiler ("build-essential" in Debian-based systems), the Python
interpreter, CMake, the "unzip" system tool, and the development
package for libuuid ("uuid-dev" in Debian) are installed.


We now make the assumption that Orthanc source code is placed in the
folder "~/Orthanc" and that the binaries will be compiled to
"~/Orthanc/Build". To build binaries with debug information:

# cd ./Build
# cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Debug ../OrthancServer/
# make
# make doc


To build a release version:

# cd ./Build
# cmake -DSTATIC_BUILD=ON -DCMAKE_BUILD_TYPE=Release ../OrthancServer/
# make
# make doc


Note 1- When the "STATIC_BUILD" option is set to "ON", the build tool
will not ask you the permission to download packages from the
Internet.

Note 2- If the development package of libuuid was not installed when
first invoking cmake, you will have to manually remove the build
directory ("rm -rf ~/Orthanc/Build") after installing this package,
then run cmake again.

Note 3- To build the documentation, you will have to install doxygen.


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

Under GNU/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 GNU/Linux distributions. Because using
system libraries is the default behavior, you just have to use:

# cd ./Build
# cmake -DCMAKE_BUILD_TYPE=Debug ../OrthancServer
# make

Note that to build the documentation, you will have to install doxygen.

However, on some GNU/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outdated.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
GNU/Linux distribution, it is also sometimes required to fine-tune
some options.

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

Other GNU/Linux distributions?
------------------------------

Don't hesitate to send us your build instructions (by a mail to
s.jodogne@orthanc-labs.com)!

The file "./Resources/OldBuildInstructions.txt" contains build
instructions that once worked for older versions of Orthanc or older
GNU/Linux distributions, but are not tested anymore. Even if they may
not work anymore as such, they can serve as a basis.

You can find build instructions for Orthanc up to 0.7.0 on the
following Wiki page:
https://orthanc.uclouvain.be/book/faq/compiling-old.html

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



Additional information
----------------------

* It has been reported that distributions coming with Boost >= 1.70.0
  might need the option "-DBoost_NO_BOOST_CMAKE=ON" to be added to the
  "cmake" command line.
  https://groups.google.com/d/msg/orthanc-users/nXq2qOndw9c/0PGnaOqiAgAJ

* Starting with Orthanc 1.10.0, if you use a distribution with an old
  version of gcc (typically gcc 4.8 on CentOS), you might have to add
  the option "-DCMAKE_CXX_FLAGS=-std=c++11" when invoking the "cmake"
  command line. This flag was previously automatically added, but this
  feature was removed according to the following discussion:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000222



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

Under GNU/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 ../OrthancServer/ [Other Options]
