 g++-4.8 is included in FreeBSD 9.2.
 
+You may also need to install the =gzstream= library with:
+#+BEGIN_SRC sh
+pkg install gzstream
+#+END_SRC
 
+Also Vidjil uses GNU make which requires =gmake= under FreeBSD.
+At the time of redacting the documentation, =g++= requires extra options to
+ensure flawless compilation and execution of Vidjil:
+#+BEGIN_SRC 
+make MAKE=gmake CXXFLAGS="-D_GLIBCXX_USE_C99 -Wl,-rpath=/usr/local/lib/gcc49"
+#+END_SRC
+The =gcc49= at the end of the command line is to be replaced by the =gcc= version
+used. 
 *** Debian Squeeze 6.0 / Wheezy 7.0
 
 g++-4.8 should be pinned from testing.
