 Posted: Wed Dec 30, 2009 3:22 pm Post subject: How to compile without net framework? |
 |
|
Everything I compile requires net framework to run. How can I avoid this?
Edit: I compile with Visual Studio 2008. I searched in compiler settings but I can't understand them.

| I create simple console application in C/C++ and on computer that has not net framework it won't run, I compile in release mode . When I compile with devc++ it runs but the application is larger in file size. In VS it gives a release file of 4kb but in devc++ is 22kb. Ow, I forgot to mention that I create an empty project without any dependencies.

look in project settings -> C/C++ -> code generation
you're probably using dll

Ok thx, now I am at work now, when I go home I will try that.
Edit: Thx slovach I found it. For anyone who has the same issue: project propeties -> C/C++ -> code generation and change runtime library from Multi-Threaded DLL (MD) to just Multi-Threaded (MT) and recompile. But there's nothing about net framework there  . How will someone know that? and most maybe ignore that because when you install visual studio packets like net framework are autoinstalled, but when you want to run your program on another computer a strange error appears on runtime, what the....

Don't use the managed framework?
New Project -> C/C++ -> Win32 -> Console
Compile with the code generation multi-threaded and the user won't even need the visual c++ redistributable libraries.

are you using unmanaged C++ right?

managed is the one that uses .net framework right? Yea I am using unmanaged C++, I want to compile an executable that will run directly, not bytecode or other shit. Which one is better/faster?

That's not .NET framework. That's the CRT, C Runtime library. To avoid that add /nodefaultlib to your linker, define your own mainCRTStartup()/WinMainCRTStartup(), make sure that the exceptions are off, and dynamically link the runtime library.
Also, if I were you, I'd avoid static linking to the runtime library, because it makes your exe huge and is waste of space.
EDIT: Oh right, remember that you'll lose all the CRT functionality, so better to stick to winapi :)

pretty sure that the CRT is actually a standard system file, so you shouldn't actually run into trouble doing that in most cases. maybe, though it's a pretty common 'trick' for getting very tiny exe's.
don't think you can rely on this with the CPRT though

lol you're right.,, what is requiered is C++ redistributable package by microsoft and not net. framework xD. Explain a little better what is a runtime library, I don't understand and why is necessary? It sounds like somethink that is required for the program to run in runtime, but what it contains and what it does?

Depends on what are you writing. If you're able to code in WinAPI only, you're fine without it. And everything on Windows should be doable in WinAPI.

If you use any standard C functions, you'll be using the runtime lib. If you stick to WinAPI, you'll be fine without it. CRT is the lib implementing the C standard library.
Also, check the WinAPI equivalents and here's a nice site.

| thank you for all this info. So runtime libraries are like dlls.

If you're using C++, you won't even touch those functions. If you're using C, you should stop using the worst C compiler on the planet.

Many of the Windows functions rely on the CRT afaik
HeapAlloc ultimately calls malloc()
so does new in C++ I think.
you can go hog wild by linking against msvcrt.lib
