How to enable C / C++ asserts?

[Torsten Robitzki]

Hi,

normally, I would set the CMAKE_BUILD_TYPE to `Debug` to enable Cs "assert" function (not define NDEBUG). Zephyr (and Nordic-Zephyr as well) has the `CONFIG_ASSERT` configuration option but this seems to only enable Zephyrs asserts. How am I'm supposed to enable C asserts (aka how to _not_ define NDEBUG)?

best regards

As far as I know Zephyr does not define the symbol `NDEBUG` for you. What makes you think that?

If you modify the sample application `hello_world` to include `assert.h`  and call `assert(0)`. What happens when you run it?

Hi Jakob,

I stumbled over this, by observing asserts, that I thought should fire, but did not. I added an `assert(false)` to my application code and it did not fire. I added

#ifdef NDEBUG
#undef NDEBUG
#endif

#include <cassert>

to the file in question and finally, `assert( false )` fired.

I have not found anything in my CMakeLists.txt that would add NDEBUG to the set of defines.

best regards
