Summary

0000895: NDEBUG and assert

Description

CMake should allow passing -DNDEBUG, in CMAKE_CXX_FLAGS_RELEASE (even if this does not exactly match the orther project we are linking to). For example we could have our own project linking to VTK, where we would pass -DNDEBUG in RELEASE, but where VTK does not specify it (since it does not need it).

man assert:
NAME
       assert - abort the program if assertion is false

SYNOPSIS
       #include <assert.h>

       void assert(scalar expression);

DESCRIPTION
       If the macro NDEBUG was defined at the moment <assert.h> was last included, the macro assert() generates no code, and hence does nothing at all. Otherwise, the macro assert() prints an error message to standard output and terminates the program by calling abort() if expression is false (i.e., compares equal to zero).

       The purpose of this macro is to help the programmer find bugs in his program. The message "assertion failed in file foo.c, function do_bar(), line 1287" is of no help at all to a user.

Notes
(0001164) Bill Hoffman (manager) 2004-06-01 12:51	CMake does allow this, I think the problem is in VTK.

(0001166) Brad King (manager) 2004-06-01 14:08	The bug is in CMake. I've modified the platform configuration files to add -DNDEBUG to the flags for release builds.
