Hello Jean-Baptitste,

I have modified "Makefile.am" in ~/modules/access" this line :

libaccess_srt_plugin_la_LDFLAGS = $(AM_LDFLAGS) -rpath '$(accessdir)'

to :

libaccess_srt_plugin_la_LDFLAGS = $(AM_LDFLAGS) -lstdc++ -rpath '$(accessdir)'

and after a make, I've got fewer link errors, about nettle library entries 
missing (but nettle 3.3 is installed on my system) :
