Building External Dependencies

True Reality v0.2-Dev Dependencies List

For best results, build the dependencies in the order they are listed. Some of them depend on the ones that were build before them.

First, Setup all the TR Environmental Variables

Note:

Install CentOS 7 with Development and Creative Workstation profile, with all options selected.

To get your CentOS to use GCC 7.3.1, you need to install DevToolset-7
After installing DevToolset, to have it permanently enabled add the following lines to your /home/<username>/.bashrc

#Source devtoolset-7
if [ -f /opt/rh/devtoolset-7/enable ]; then
. /opt/rh/devtoolset-7/enable
fi

Make sure you download tar or gz files for all dependencies not Zip. Linux does not know how to handle certain line endings after unziping code files from a Zip archive and introduces build errors.

Build Debug libraries before Release because some projects will build separate debug and release libs but still overwrite software and tool files from one binary build to another, and it's preferable to have those in Release builds over Debug

My Ext folder is on /home/maximserebrennik/Desktop/Development/Ext Yours will be somewhere else, so you need to adjust your path accordingly.

We suggest placing the Ext folder in your TR directory, the same place where you are pointing with $TR_ROOT. This document will assume you placed the Ext folder in $TR_ROOT/Ext.

Every time you open a terminal for a build, before running CMake run the following export commands with your Ext folder path:

export PATH=$TR_ROOT/Ext:$TR_ROOT/Ext/bin:$TR_ROOT/Ext/include:$TR_ROOT/Ext/lib:$TR_ROOT/Ext/lib64:$PATH

export LD_LIBRARY_PATH=$TR_ROOT/Ext/lib:$TR_ROOT/Ext/lib64:$LD_LIBRARY_PATH

Final Edits

Go to your Ext folder and move all files and folders in lib64 to lib. Then delete all folders except bin, lib and include.
Place the Ext folder into your TR repo folder before trying to build and install TR.
