+Compilation errors
+==================
+
+This section is here to help you with the build process, and help you fix dependency issues or workaround compilation errors if it happens on your distribution.
+
+
+RapidJson
+---------
+
+Some versions of RapidJson do not build with newer compilers, while others build only with newer ones.
+The version provided in README.rst should work for older compilers. Otherwise, consider pulling a newer version.
+
+Qt5
+---
+
+To use Qt5, you should add the --qt5 option to the ccb.py line in Makefile.
+On some distributions, you may need to replace the lines in bootstrap/cmake_modules/FindBootstrap.cmake from ::
+    find_package(Qt5Core         REQUIRED)
+to ::
+    find_package(Qt5 COMPONENTS REQUIRED Core)
