I am debugging a multi-threaded application with gdb, but when I start the program in gdb I get the warning:
warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.
I can still debug, but I can't debug anything other than the main thread. I have read forums that suggest installing the packages libthread-db1 and glibc-dbg, but this does not correct the problem for me.
On my machine I have the 3 files /lib/libthread_db.so.1, /lib/.debug/libthread_db-1.0.so, and /lib/libthread_db-1.0.so. I tried creating symbolic links in /lib with the name libthread_db.so, one time pointing at the /lib/libthread_db.so.1 file, and another time pointing at the /lib/libthread_db-1.0.so file, and also I created the symbolic link /lib/.debug/libthread_db.so pointing to /lib/.debug/libthread_db-1.0.so, all with no luck.
In gdb I have tried setting libthread-db-search-path to /lib (with the symlink once set to libthread_db.so.1, and once to libthread_db-1.0.so, and also set to /lib/.debug.
Any suggestions? I am using Angstrom Linux v2.6.39 for the BeagleBoard-xm.
