GDB does not see any stream except

Question

GDB does not see any thread except the one in which the failure occurred; or SIGTRAP kills my program when I set a breakpoint.

Answer 1

This often happens on Linux, especially for embedded purposes. There are two common causes:

• you use glibc and you shared libpthread.so.0
• mismatch between libpthread.so.0andlibthread_db.so.1

GDB , " ", glibc glibc. libthread_db.so.1 ( glibc), . , libthread_db.so.1 libpthread.so.0 . , libthread_db.so.1 libpthread.so.0.

: strip --strip-debug libpthread.so.0 strip libpthread.so.0.
