< incurable diseases >GDB debugging multithreaded Program error: Interrupted system call

One. Ubuntu system, using the GDB debug program, the method is as follows:

1) Compile the source code, GDB can only debug executable files. If you compile a C + + program with CMake, you need to add the following flag to the CMakeLists.txt, which provides basic debugging information and intermediate variable information during debugging.

Set (gcc_coverage_compile_flags "-G") Set (Cmake_cxx_flags  "${cmake_cxx_flags} ${gcc_coverage_compile_flags}")

2) terminal jump to the directory where the compiled executable file is located, run gdb xxxx to start debugging the program.

Two. Debug multi-threaded threads

When I used GDB to debug multi-threaded threads, the error "interrupted system call", I referred to 37906091

Workaround: Set GDB to Non-stop mode, set as follows.

Open ~/.gdbinit (If you don't have this file, create a new document of the same name yourself), then add three lines.

set target-async 1set  pagination offset non-stop on
