I am already on lede master.
maybe you mean olsr-master instead of ledes olsr version? so i will try
to find a possibility for finding and compiling that.
meanwhile i got another crash on the same device, same olsr-version, but
with different debug information:
[New LWP 1978]
warning: Can't read pathname for load map: Unknown error -1.
warning: Could not load shared library symbols for 6 libraries, e.g.
/lib/libgcc_s.so.1.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?
