It's not clear to me why, but the files labelled as 'eglibc-thread-db' in the eglibc recipe end up in the 'libthread-db1' package, so that mystery is solved. I still don't know how to get the libpthread library to be not stripped (which it seems is what it takes to make GDB happy in this case). -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
