InstallingROOT

@@ -98 +98 @@
 We have encountered problems with root 6.18.04 (and most likely others) and some database related FACT++ tools when root compiles its own ssl-library. What happens is that under some cirumstances the system ssl-library jumps into functions compiled by root and the program crashes. A solution is to ensure that root uses the system library instead. This is requested adding `-Dbuildin_ssl=OFF` to the cmake-call. It should also be enough to ensure that libssl-dev is installed before the call to cmake.
 
+At least root 6.22 has an incompatibility in its build-system (precisely in RootMacros.cmake) with the Mars build system. Either you need to use another root version or you patch RootMacros.cmake like follows:
+{{{diff
+683c683,684
+<     add_custom_target(${dictionary} DEPENDS ${dictionary}.cxx ${pcm_name} ${rootmap_name} ${cpp_module_file})
+---
+>     get_filename_component(dictionary_name ${dictionary} NAME)
+>     add_custom_target(${dictionary_name} DEPENDS ${dictionary}.cxx ${pcm_name} ${rootmap_name} ${cpp_module_file})
+}}}
