I've never used abe to build canadian cross like this, so I don't know the level of support for it. In theory it seems like it should work. It is simpler to just build natively on a juno box though, which is what I do. > RUN: copy_gcc_libs_to_sysroot > "/home/user_name/vpathak/build_abe/builds/destdir/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc > --sysroot=/home/user_name/vpathak/build_abe/sysroots/aarch64-linux-gnu" > /home/user_name/vpathak/abe/lib/make.sh: line 962: > ./builds/destdir/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc: cannot execute > binary file The problem here is that abe is using the host compiler binary when it should be using the build compiler binary. Abe would need to keep track of two compiler versions, and remember that one runs on the host and one runs on the build machine. The GCC makefiles have this support, but it appears that the abe scripts do not. It should be possible to add this to abe. You could try filing a bug report against abe for this problem. > ------------------------------------------------------------------------------------------------------- > I had to disable gdb compilation.

This isn't part of the sysroot that abe creates. So yes, this isn't going to work unless you configure gdb to disable tui, or add libncurses to the sysroot. Again, you could file an abe bug report for that.
