Fortunately those binaries are not required; you should be able to use the dynamic ones just fine. If you want the ones that have the support libraries compiled in statically, I recommend moving -lm from inside of the static link block in TOOL_STATIC_LDFLAGS to after the -Wl,-Bdynamic. I've done that at my end now; thanks for the report. The same should work for the LIBS setting for FFTB's Makefile.</div><div><br></div><div>The error you're seeing when running art most likely is a result of your system's shared library search path not including /usr/local/lib/.
