I am using the linaro LAMP image on the Foundation model from ARM, as described at: - http://www.linaro.org/engineering/engineering-projects/armv8 - http://releases.linaro.org/latest/openembedded/aarch64/
Unfortunately the 32 bit support is not yet in so I am using a statically built v7 binary for testing. The newer releases of Ubuntu for AARCH64 are doing better in that respect, I have to give it a try. Do you have an idea what/where to check for libdw compat support? I just quickly browsed through the code and found the uses of the ELFCLASS32/ELFCLASS64 macros interesting. Do you need testing etc. in order to be able to merge the aarch64 branch? Please let me know! > > Cheers, > > Mark > Cheers, Jean
