Re: Trouble running guile cross-compiled using buildroot

[Peter Spierenburg]

I noticed that some info from the backtrace was removed by the size 
optimization flag in buildroot, so I rebuilt without optimization. Here is a 
new backtrace.

Could you show the backtrace, using (on the ARM device):

  $ gdb --args guile
  (gdb) run
  # runs until it aborts
  (gdb) bt

?

Also, could you show the Buildroot recipe?  Cross-compilation of Guile
requires a same-version native Guile.

Thanks,
Ludo’.
