Dev C++ uses the gcc and g++ compilers.
The following compiler options are available if you are using gcc or g++.
-g
This is the default debug format. This will normally choose the DWARF symbol format.
-gdwarf
The DWARF symbol format.
-gstabs
The STABS symbol format.
-gCoff
The COFF symbol format. This does create a lot of unnecessary symbols, making symbol parsing slower.
You can edit the compiler and linker options by choosing Project Options... from the Project menu.
Compiler and Linker options
When you have edited the project options you need to rebuild the software for the options to take effect and create the debug information.
