Question

I have very simple program to simplify things as shown below...

#include <openssl/evp.h>
int main (int argc, char *argv[])
{
        EVP_CIPHER_CTX ctx;
        EVP_CIPHER_CTX_init(&ctx);
}

It references 1 function in a DLL(libeay32.dll from openSSL). I build it with settings "Linker->Input->Additional Dependencies->" pointing to where the libeay32.lib is stored. However when you run it will complain with "This application has failed to start because LIBEAY32.DLL was not found". I want to build it so I can have this DLL built into the executable so it doesn t need to look for it on client machines.

If you can assist can you please explain it in small baby steps so I can understand as I m a beginner to Visual Studio.

Answer 1

What you re asking is to link statically to your executable.

Here s a guide on how to get OpenSSL to compile to a static library on various platforms.

Answer 2

This isn t exactly what you re asking for, but you could just put the DLL file in the same folder as your compiled binary.

Answer 3

Unfortunately you cant include a dll in a .Net executable at this time using Visual Studio.
Some people have managed to solved this by using Mono instead.

Here are some links discussing it:

Answer 4

The problem is not related to the linker or Visual Studio. The problem is running the application. You must place the library libeay32.dll in a directory that is included in the PATH or in the same directory where the executable.

EDIT: Check Packing an exe + dll into one executable (not .NET)

HTH.
