How can I completely disable calls to assert()?

Question

My code is full of calls to assert(condition). In the debug version I use g++ -g which triggers my assertions. Unexpectedly, the same assertions ar

Answer 1

Yes, define NDEBUG on the command line/build system with the preprocessor/compiler option -DNDEBUG.

This has nothing to do with the debugging info inserted by -g.

Answer 2

You can either disable assertions completely by

#define NDEBUG
#include <assert.h>

or you can set NDEBUG (via -DNDEBUG) in your makefile/build procedure depending on whether you want a productive or dev version.

Answer 3

You must #define NDEBUG (or use the flag -DNDEBUG with g++) this will disable assert as long as it's defined before the inclusion of the assert header file.

Answer 4

The -g flag doesn't affect the operation of assert, it just ensures that various debugging symbols are available.

Setting NDEBUG is the standard (as in official, ISO standard) way of disabling assertions.

Answer 5

Use #define NDEBUG

1 The header defines the assert macro and refers to another macro,

NDEBUG

which is not defined by <assert.h>. If NDEBUG is defined as a macro name at the point in the source file where is included, the assert macro is defined simply as

#define assert(ignore) ((void)0)

The assert macro is redefined according to the current state of NDEBUG each time that <assert.h> is included.
