I’m using Arch Linux, which is very recent. This only means that I notice issues ealier than, say, ubuntu.
binutils release notes:
http://sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/src/ld/NEWS?rev=1.121&content-type=text/plain&cvsroot=src&only_with_tag=binutils-binutils-2_22
What this means is that indirect linking doesn’t work anymore, hence juce example application Makefiles don’t work anymore.
-ldl -lXext is missing in a number of those.
Example output:
Compiling JuceLibraryCode1.cpp
Compiling JuceLibraryCode2.cpp
Compiling JuceLibraryCode3.cpp
Compiling JuceLibraryCode4.cpp
