Creating symbol table for gdb using cmake

Question

Is there any way to create only symbol table using cmake for gdb ?

Answer 1

Add this line to the file CMakeLists.txt:

set(CMAKE_BUILD_TYPE Debug)

Answer 2

The usual way to produce debugging information for gdb is to pass -g to the gcc or g++ compiler (and also at linking time).

Look into the Cmake FAQ for how to get a debuggable executable.

Answer 3

compile in Release mode optimized but adding debug symbols, useful for profiling :

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ...

or compile with NO optimization and adding debug symbols :

cmake -DCMAKE_BUILD_TYPE=Debug ...
