fatal error LNK1104: cannot open file 'LIBC.lib...

'libc.lib' usually comes with VC++ and should be located in your 'Lib' directory, check your Visual Studio installation directory.

There is no libc.lib. I have VS 2008.

>> There is no libc.lib. I have VS 2008.

This is most unlikely. Just double checked that, it should be there. If not, there's something wrong with your installation. Also, could you maybe post your linker settings?

I'm not sure, but libc is an old C run-time library for the so called single threaded model.
So, if I'm right, this option (C Run-Time Library) should be changed in the project for Multi-Threaded (/Md).

I have Multithreaded Debug DLL.

Maybe the new library you're adding is compiled using the static CRT. In that case you'll have to change your linker settings to that also, or you'll get linker errors.

Have you tried to add this libc to the ignore libraries list?

I did it and now it is ok.

It is compiled with multi threadeddebug ; so it is not  Multithreaded Debug DLL.

Now I have a linker error

Torch3.lib(general.obj) : error LNK2019: unresolved external symbol __iob referenced in function "void __cdecl Torch::error(char const *,...)" (?error@Torch@@YAXPBDZZ)
1>.\Debug/I90Controller.exe : fatal error LNK1120: 1 unresolved externals

It's good.
"Torch" is not from the C Run-Time library.
:)

Should I close this question and open another one about this?

You already have it:
http://www.experts-exchange.com/Programming/Editors_IDEs/C_CPP_CS/Visual_CPP/Q_24819659.html

it was exactly about the touch

>>"Torch" is not from the C Run-Time library.

But '__iob' is - ignoring the reference to 'libc.lib' causes this error. '__iob' also is not listed in the errors in that othre Q.

Torch3.lib - what is this? do you have a source code maybe?
Sorry, I've never seen RL Toolbox.

Yes..but nobody answered me on that question so that is why I opened another one. I did what they told me to do in that question and nothing changed...I still have the error.

Torch3.lib - what is this? do you have a source code maybe?


I don't have any sourrce code only the .lib . And people told me to added to my project and that is what I did.

ok.
You don't call any error method in your code?

>>"Torch" is not from the C Run-Time library.

But '__iob' is - ignoring the reference to 'libc.lib' causes this error. '__iob' also is not listed in the errors in that othre Q.


so I have this error because i am ingoring the libc.lib ? What can I do if this is the case?

I think this is the source code:
http://en.pudn.com/downloads115/sourcecode/math/detail484646_en.html

The problematic function is declared as:
void error(const char* msg, ...);

OK, this is a wild idea, but what happens if you add the following to your code?

#include <stdio.h>
 
char _bufin[_INTERNAL_BUFSIZ];
/*
 * FILE descriptors; preset for stdin/out/err (note that the __tmpnum field
 * is not initialized)
 */
FILE _iob[_IOB_ENTRIES] = {
        /* _ptr, _cnt, _base,  _flag, _file, _charbuf, _bufsiz */
 
        /* stdin (_iob[0]) */
 
        { _bufin, 0, _bufin, _IOREAD | _IOYOURBUF, 0, 0, _INTERNAL_BUFSIZ },
 
        /* stdout (_iob[1]) */
 
        { NULL, 0, NULL, _IOWRT, 1, 0, 0 },
 
        /* stderr (_iob[3]) */
 
        { NULL, 0, NULL, _IOWRT, 2, 0, 0 },
 
};

I have it already sorry about that. I already build the RL toolbox library.

OK, this is a wild idea, but what happens if you add the following to your code?

Where chould I added? in the I90Controller.cpp?

It will be very bad if we add this function to your code?
just
void error(const char* msg, ...)
{}
somewhere in a cpp-file.

>>Where chould I added? in the I90Controller.cpp?

In any of your source files, which one does not really matter.

really does not matter

I'm late with all my comments here :)
So I'm leaving

Please stop. Please remove all changes you did in the code and remove libc from the ignore library list.
Probably you have VS 2008 Express Edition.
I think, you just need to install this SDK:
http://msdn.microsoft.com/en-us/windows/bb980924.aspx

Have you tried to add libcmt.lib to the dependecies? I mean "Additional Libraries" in the project settings.

I have professional edition. Which one i should install? It is for wind 7, and vist I have win xp.

So try to ignore msvcrtd library - this is the debug version of the C Run-Time library. Next - ignore libcmt.

now I have 1403 errors.

similar to this one

I think it is easier to find a fixed version of this RX Toolbox library or install VS 6 or 2003 then to fix all errors you have.
Can you go back and recover a situation with 1-2 compilation errors?
