There have been many infrastructural changes since then so it's not really a surprise that this may be hard... > Sicne tools like crosstool-ng are able to use older uClibc I assume there > should be a way to do it. > I was wondering if there is an "official" or "recommended" way to do this. Yes: build your toolchain with crosstool-NG, and import it as an external toolchain in buildroot. > When I try to statically build binaries using a newer uClibc and put it > on my target machine they crash. That is weird... Does the binary really not use any shared library (check with readelf)? How/why does it crash? Can you get a backtrace in a debugger?
