I'm using cmake to build the debug version via cmake -DCMAKE_BUILD_TYPE=Debug ..
I got CMakeCache.txt, CMakeFiles, Makefile, cmake_install.cmake files/folders and the compiled binary, say test, in the build folder.
when I start the gdb by gdb ./test I got the following out put

"/Users/sln/Project/repos/C++/Primer/debug/./test": not in executable format: File format not recognized
And I add the break point to main function by (gdb) break main and the following message was print out
No symbol table is loaded. Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n])
By input y to the upper question I got
Breakpoint 1 (main) pending.
Then (gdb) run command gives the error
Starting program:
No executable file specified.
Use the "file" or "exec-file" command.
And finally (gdb) file leads to
No executable file now.
No symbol file now.
Question: I wonder which part was wrong?
Here is my CmakeList.txt file
cmake_minimum_required(VERSION 2.8)
project(Test)
set(CMAKE_CXX_STANDARD 11)
if(NOT CMAKE_BUILD_TYPE)
set(CMAKE_BUILD_TYPE Release)
endif()
add_executable( test
${CMAKE_CURRENT_SOURCE_DIR}/src/main.cpp
${CMAKE_CURRENT_SOURCE_DIR}/src/test_nav.h
)
