Hi,
I was wondering in what case the following code defining ASSERT will be processed by gcc :
Is it when specifying -g to gcc?Code:#ifdef DEBUG #define ASSERT(x) if(!(x)) { \ std::cerr << "ASSERT FAILED IN " << __FILE__ << ":" << __LINE__ << endl; \ abort(); \ } #else #define ASSERT(x) #endif
Is ASSERT defined as such same as assert() in assert.h?
Thanks!
Whenever DEBUG is defined. gcc will never define it itself (even with -g). You must define it manually.Originally Posted by lehe
The built-in assert will trigger by default, unless NDEBUG is defined. Again, the compiler DOES NOT DEFINE THIS FOR YOU. You must define it yourself when building for release.
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
I'm very much doubting that...
compiled with gcc -g dbg.c, and then executing will show "No Debug" - at least using gcc-mingw 3.4.Code:#include <stdio.h> int main() { #if DEBUG printf("Debug\n"); #else printf("No Debug\n"); #endif return 0; }
There is a symbol "NDEBUG" that is normally set by the compiler in "NO Debug" mode.

Compilers can produce warnings - make the compiler programmers happy: Use them!

I didn't think the compiler ever did that itself. I want to be able to enable asserts in release mode, or disable them for a debug build, if I want. Why should the compiler prevent me?
And anyway, "release" and "debug" are just conveniences -- all that's actually real are the set of compiler switches. The -g flag means symbolic debugging information, not "build for debug." I can ask for optimization and debug at the same time if I want..
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
Sorry, you are right, I'm wrong. I'm probably confusing this with the "regular build setup in Visual studio", which normally DOES set NDEBUG in the release mode.
