Re: [Quantlib-users] Issue Debugging the actual QuantLib core code

[Jonathan S. <sw...@gm...>]

Hi Alex,

I would try to add -g and remove -O2 from your CXXFLAGS for debugging.

You can also try installing the CMake extension for VSCode and then choose
one of the debug build presets. This should enforce consistent build flags
between the examples and the library.
