I want to include iostream inside a c++ dll file but am getting "fatal error: iostream: No such file or directory" error.
How can I include header files in a dll file?
There's no such a thing like "include header files in a dll file".
What you can do is:
include header files in a source code file (i.e. *.cpp),
then compile it to create a shared library (DLL file on Windows platform).

I have been trying to include Botan files into my project, but so far, it hasn't been working because it can't find the files. I am using Clion IDE with Cmake and in the CmakeLists.txt file, I have included the relative path to the files I want to add:
include_directories(./Botan/include)
From there, I want to add the sha2_64.h file to one of my header files, so I have the following in my header file:
#include <botan/sha2_64.h>
The autofill worked properly in Clion and it found botan/sha2_64.h but when it came time to build the project, I get the error "Cannot open include file: 'botan/sha2_64.h': No such file or directory" Why can the autofill find the file, but the compiler can't? I even tried accessing the file by using:
#include "../Botan/include/botan/sha2_64.h" //Relative path from my header file to sha2_64.h
This still resulted in the file not being found. I know that this path is correct as Clion's autofill finds it no problem. I just can't figure out why the compiler can't find the file.
I am reading through the shogun C++ library code and while reading in the src folder, I notice that many files include the header file shogun/lib/config.h, but I cannot find this header file in the source code.
For example, if you look at the header file SGMatrix.h you can clearly see that it has the following include statement:
#include <shogun/lib/config.h>
yet you can't find config.h anywhere in shogun/lib. Where can I find this header file?
The config.h is being created during configuration, i.e. running cmake, and the actual content is based on your system's properties. the template of for the file can be found in src/shogun/lib/config.h.in
With Visual Studio 2013 I'm writing a Dynamic Library and I need to use some third-party libraries. Each library comes in the form of header .h, a .dll and .lib files. I added the library's directory to my project, I changed the "Configuration Properties -> C/C++ -> Additional Include Directories" to include the header file and I added the .lib file to the Additional Dependencies of the Linker.
If I try to include the header .h in my .cpp file using
#include "library.h"
everything works fine and the compiler it gives no error. But if I put this line in my header .h file and try to compile I get this error:
error C1083: Cannot open include file: 'library.h': No such file or directory
Any ideas? Thanks in advance.
I am creating a Visual C++ sample project where i need to include a third party library.
I added the lib and added the include directory.
But my problem is now, that the header files of the library have the following line in their header files:
#include <QtCore/QVector>
and the compiler error is:
error C1083: Cannot open include file: 'QtCore/QVector': No such file or directory
I have the used dlls, but I am stuck how to include them?!
I solved it with installing Qt locally and adding it to the PATH.
I have a library (lib file + .h header file). I like to turn it into a DLL so I can easiliy use it in VB6. Is there a convenient way to do this?
Simply include the header file an a .def file in a new dll project and link it with the static lib.
