Component Version Requirements
=============================================================================

RStudio requires relatively recent versions of a number of components. It is
therefore likely to only correctly configure and build on more recent Linux
systems. Specific version requirements for various components include:

- R 3.0.1
- CMake 3.4.3 or newer
- Boost 1.69
- Qt 5.12.8 [Required only for Desktop]
- patchelf 0.9 [Required only for Desktop]
- some older Linux platforms (OpenSUSE 42.3, Ubuntu Trusty) can only
  build Desktop with Qt 5.10.1 due to unsatisfied dependencies

Installation of Qt SDK
=============================================================================

To build RStudio Desktop, install Qt from https://qt.io. Include the
QtWebEngine component.

Installing Dependencies for Debian/Ubuntu, Fedora, RedHat/CentOS, or OpenSUSE
=============================================================================

1) R installation - building RStudio requires that a version of R be 
previously installed within a location where the R executable can be run from
the system shell (e.g. /usr/bin or /usr/local/bin). Building R from source
and then executing 'make install' will conform to this requirement as will
installing it using the system standard package management tools (apt-get, 
yum, etc).

2) Run the install-dependencies script appropriate to your platform's
package management system (to optionally exclude installation of the Qt
SDK be sure to specify the --exclude-qt-sdk flag as described above).

   ./install-dependencies-debian
   ./install-dependencies-yum
   ./install-dependencies-zypper
   
Note that this script will install Boost 1.69 in the /opt/rstudio-tools/boost
directory (the /opt/rstudio-tools directory is used to insure that this 
installation of boost doesn't conflict with other versions of boost installed
on the system). This part of the installation will take a few minutes since
it requires that boost be built from source for your system.


Installing Dependencies for Other Systems
=============================================================================

If the system you are installing on is either older than the minimum required
versions listed above or another Linux distribution entirely, then you should
do the following to make sure you have fulfilled all dependencies:

1) The Dockerfiles in the docker/jenkins folder contain the definitive 
dependency requirements for the platforms that RStudio is built on and can 
serve as a guide in determining which referenced libraries must be available
on your system.

2) Run the install-common script from dependencies/common (which will 
install Google Web Toolkit, Hunspell dictionaries, MathJax, Boost 1.69, and 
other dependencies):

NOTE: To build without crashpad support, define RSTUDIO_DISABLE_CRASHPAD=1 
before running the script; otherwise, pass the --install-crashpad-sudo
option so crashpad can be installed to opt/rstudio-tools/crashpad.

   ./install-common --install-crashpad-sudo

OR

   RSTUDIO_DISABLE_CRASHPAD=1 ./install-common

3) Optionally install the Qt SDK, including QtWebEngine, from
https://qt.io. You should do this if you are building the Desktop version 
and don't have Qt and QtWebEngine installed on the system:

4) If your system doesn't meet the minimum version requirements for CMake 
(3.4.3) you can download a Linux binary of the latest version of CMake here:
