We have tried to support non sysroot-capable toolchains, but it was the source of various issues, and since sysroot is now quite ancient and available in most toolchains, it sounded like a reasonable tradeoff. > but I think the problem is rooted in the SYSROOT value being used to > verify glibc... > > has anyone configured Buildroot to use ELDK as the external toolchain > to use for builds? I wanted to, but I never understood how to get just the ELDK toolchain and not a complete distribution. I'll try to see if I can test this toolchain, but if you have some simple setup instructions to get just the toolchain, that would be great.
