ndebug

I'm just trying to build a cmake project in debug-mode to enable asserts. I tried the following versions: cmake -D CMAKE_BUILD_TYPE:STRING=Debug -L ../../ cmake -DCMAKE_BUILD_TYPE:STRING=Debug -L ../../ cmake -DCMAKE_BUILD_TYPE=Debug -L ../../ Unfortunately none of theese has the desired effect - that CMAKE_BUILD_TYPE is set to Debug (and therefore the NDEBUG -flag is not passed to gcc). Additionally I added variable_watch(CMAKE_BUILD_TYPE) to my main CMakeLists.txt to check whether the value get's overridden somewhere. But the first output is a READ_ACCESS in my main Additionally I added

CMake is being used to compile some C++ files. There are assert calls in the code. These calls are disabled in Release mode of CMake. It defines NDEBUG in Release mode, I guess. If I'm interested in having assert in Release mode of CMake, how do I enable it? 1 If you interested in assert functionality only in your own code then the simple one solution is to provide custom assert. For instance: #if (MY_DEBUG) # define MY_ASSERT(A) ... checks here ... #else # define MY_ASSERT(A) ... ignore A ... #endif Use option to enable/disable assert: # CMakeLists.txt option(ENABLE_MY_ASSERT "Turn on MY

I'm interested in what purpose various platforms / compilers ("implementations") / frameworks assign to the the C and C++ preprocessor macro NDEBUG . The C as well as the C++ standard only mention this definition once, namely to control the behavior of the assert() macro. I would ask to include only specific answers, where you know that a certain platform / framework / library for C or C++ uses the NDEBUG definition to enable or disable anything else in addition to the standard defined assert() macro . One reason for asking this question has been that MS (Visual-C++) always(?) uses "their"

Our build system has somehow changed such that optimized builds are no longer getting the -DNDEBUG added to the compile line. I searched our makefiles and don't find this. So the question is, where does -DNDEBUG originate for most people and how might that have changed? Before we did have -DNDEBUG and I don't think this was removed from any of our makefiles. Thanks. -William Since the compiler can't decide on its own when to add the NDEBUG define and when not to, the flag is always set by either the makefile or project file (depending on your build system). It is really difficult to answer
