Re: When I have compiled a Visual C++ 2008 program, what DLL's does the resulting .EXE file need, to run on another computer?

17-Dec-07 3:33

I have the free download version of Visual C++ 2008.

I asked the above question recently, and was told to read http://msdn2.microsoft.com/en-us/library/zebw5zk9(VS.80).aspx . However, that page is for Visual C++ 2005, which uses different DLL's and mentions things that my Visual C++ 2008 does not have. So, please:

Which of the relevant Visual C++ 2008 DLL's do what and are needed for what?
Can they be merely put in the same directory/folder as the .EXE file, or do they have to be in a particular directory structure?

run Dependency Walker[^] to figure that out

Thanks.

I tried it: I installed it; I dragged typecase_vc.exe into it, and it made a massive list of names of DLL's.

I then tried it on typecase.exe, which was compiled on my old Borland C++ 4.5 compiler, and I know that it only needs a Borland DLL called CW3215.DLL to make it run on other computers; but for typecase.exe Dependency Walker also made a massive list of names of DLL's. Of those, the rest are presumably permanent Windows DLL's.

Please how do I tell Dependency Walker not to list DLL's which are in Windows?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I compiled typecase_vc.exe under Windows Vista. When it is accompanied by the necessary DLL's, which versions of Windows would it run under?

actually, Depends.exe returns every dependency... but most of the time, the DLLs needed are Windows DLL (so, no need to provide them once again).

There's no way for Depends.exe to know of DLLs that are linked explicitly.

So read the page MSDN has that discusses deploying VS2008 applications which the other one you supposedly read has a link for. Roll eyes | :rolleyes:

Thanks. On top right corner of the Determining Which DLLs to Redistribute" page, I found and followed a link to the "Determining Which DLLs to Redistribute" page for 2008, which lists these DLL's: atl90.dll (Active Template Library); msvcm90.dll msvcp90.dll msvcr90.dll (C Runtime and Standard C++ Libraries); mfc90.dll mfc90u.dll mfcm90.dll mfcm90u.dll mfcmifc90.dll . But of those, atl90.dll mfc90.dll mfc90u.dll mfcm90.dll mfcm90u.dll mfcmifc90.dll do not seem to be anywhere in my C:\Program Files\Microsoft Visual Studio 9.0\ directory tree.

That page says "This page is specific to Microsoft Visual Studio 2008/.NET Framework 3.5", but also "Redist.txt is located in the Program Files\Microsoft Visual Studio 2005 directory on the second Visual Studio 2005 product CD or on the DVD.". Please what is happening. I am sorry to take up so muc of your time.

But do they exist in your c:\windows\system32 folder?

They'll be in a subfolder of your Windows\winsxs folder.

Take a look at the manifest file generated by your project. There you can get the
version of the VC runtime DLLs your app is using. That will tell you which winsxs
folder to find the DLLs in.

You really need to study the deployment docs if you want to do anything beyond
just running the end-user redistributable installer on other machines.

What difference does that make to your deployment problem?

Anthony Appleyard wrote:

I can't be sure. Maybe you are assuming that all you need to find is a magic list of files and you can take it from there. Deploying VS2008 C++ applications may not work as you assume.

Starting from that first page you posted the URL of you can follow links to many pages of information regarding deployment of a VS2008 VC++ application. I suggest you stop typing questions into forums and start reading the documentation.

Get lvalue through rvalue

George_George17-Dec-07 2:56

17-Dec-07 2:56

Hello everyone,

I do not know how in the following code, rvalue -- return of X(), could result in a lvalue finally and binded to a non-const reference input parameter of function f.

Any ideas?

struct X {


};

void f (X& x) {}

int main()
{
	f (X() = X());

	return 0;
}

thanks in advance,
George

Hey man, what are you trying to do with the following statement?

George_George wrote:
f (X() = X());

f(X());

isn't enough for you?

BTW
You're passing a reference to a temporary object to function f.

Thanks CPallini,

Why you change my code from f(X() = X()) to f (X())? Are they the same? Could you try to compile my code please?

If you change my code to f (X()), the code can not compile. But my code can compile, why? It is a question to you. Smile | :)

CPallini17-Dec-07 3:25

The code compiles (as it should do) in both cases. I've already made a test.

I've done and indeed only your dirty trick compiles. Probably (I have no certainties at this point) you're stressing a dark corner of the C++ standard: the assignment operator breaks the r-value nature of X().
And IMHO it is weird since you cannot do that on built-in types.

because he asked a question.

Do you have a problem with questions ?

Do you fear that simple '?' character ?

can't you just answer when we need more informations about what you're trying to do ?

George_George wrote:

lammer

writing f(X() = X()) just has no sense. so re-read CPallini's question again, and reply to him.

George_George wrote:

WTF have you ever written ? that's impossible and makes merfect sense to pass a brand new object as a function parameter.

Thanks to answer. Unsure | :~

Hi toxcct,

Please makes your hands dirty with this sample. It is not very hard. My thoughts are,

f (X().operator=(X()));

the copy assignment operator is invoked, and this can handle an rvalue as its argument. Then, it returns a reference, so f() can handle the reference as it is an lvalue.

It is appreciated if you could comment and correct me if I am wrong. Smile | :)

regards,
George

toxcct17-Dec-07 3:45

your thoughts are correct about the operator=().

however, it's perfectly not clean to write such a code...

and last, f(X()) will get the reference returned by the X::X() constructor and make it its parameter...
