May 26, 2004 dmc executables larger? | ||||
---|---|---|---|---|
| ||||
Hello, I've looking into DMC and getting a feel for it as well as the free Visual C++ compiler. I haven't tested anything big yet, but it seems for small programs the exe file sizes produced by DMC are larger then the ones produced by the visual c++ compiler. Can anyone explain this? I have also noticed that the obj files are oppisite in relation. DMC produces smaller OBJ files. Does this have something to do with the way that I am linking? Here are a few examples. ---hello.cpp--- #include <windows.h> int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { MessageBox(NULL, "Hello World!", "Hello", MB_OK); return 0; } ---end hello.cpp--- cl hello.cpp user32.lib produces exe filesize = 22,528 B dmc hello.cpp user32.lib produces exe filesize = 30,236 B That seems like quite a difference for such a small program. I've also been going through the opengl tutorials at nehe.gamedev.net and the same results apply. For example lesson2: cl lesson2.cpp opengl32.lib glu32.lib user32.lib gdi32.lib exe filesize = 40,960 dmc lesson2.cpp opengl32.lib glu32.lib user32.lib gdi32.lib exe filesize = 46,620 Just trying to figure out what is going on. Thanks Kalon |

I assume the difference in the runtime library (RTL). It seems that the RTL for DMC is bigger than the RTL of VC++. There is nothing you can do about this and in principle this has nothing to do with quality of the compiler.

There is nothing you can do about this and in principle this has nothing to do with quality of the compiler. The DMC runtime is a little larger because it contains a bunch of code to interpret exceptions generated by VC++ DLLs. |
