OPENSSL_Uplink(0099E000,07): no OPENSSL_Applink

[念材 杨]

hi all

I meet a run time error "OPENSSL_Uplink(0099E000,07): no OPENSSL_Applink" which feaze me several days.
this is my project description:
I had download openssl-0.9.8i. then build it and install it correctly following the INSTALL.WIN32 instruction.
I use vs2005 to develop my project
and I had set vs2005 environment such as "MultiThread Debug DLL" etc. Because it works well in my other projects.
this project is a bit different because the below function is called by a dll project. but the function is the same in dll project and application project.

this function use a pass in a buffer (indata) , and expect a buffer (outdata) out. outdata contains encrypted data.

please help me ! thank you for your kind in advance.

by the way, I wirte above EncryptData function referring to rsa source code.

Hm, never used this OPENSSL_Uplink/Applink glue before... (I have my
own OpenSSL MSVC2005 projects, which I always use inside my solutions)

Anyway, a quick check leads me to two possible answers:

1) somewhere APPMACROS_ONLY was #define'd before your actual

Post by 念材 杨
extern "C"
{
#include <openssl/applink.c>
}

code bit.

A simple change should be able to verify if this is actually the matter:

extern "C"
{
#undef APPMACROS_ONLY
#include <openssl/applink.c>
}

as then the problem should be gone.

However, there's a chance:

2) ... that you are compiling this code into a DLL of your own (given
your description of the issue, my guess is this is what you are doing.
Correct?).

Given that the Uplink code looks at the *application module* for the
Applink export, you may not find it when it is actually exported from
a DLL instead of the EXE itself.

NOTE: the above is 'guesswork': I haven't checked.


To fix the above, moving the

Post by 念材 杨
extern "C"
{
#include <openssl/applink.c>
}

code snippet to the main application source code should resolve the
matter, preferrably by placing it in the same source file as your
WinMain() / main() function.



To help you see who exports what and depends on whom, you may search
the Net for a free tool called 'Dependency Walker' (
http://www.dependencywalker.com/ ) which is a very handy tool when you
need to check what is going regarding DLL/EXE dependencies and
function/data import/exports.

hi Ger Hobbelt
thank you soooooooo much .
your answer 2) solve my problem well.
because there exists libeay32.dll ,ssleay32.dll ,my own dll and my application. my own dll call libeay32.dll and ssleay32.dll. And my application call my own dll.
according to Ger Hobbelt's suggestion 2), firstly I used a tool to analyse the exports functions of libeay32.dll ,ssleay32.dll and my own dll. I found that dll exports functions don't contain OPENSSL_Applink() function. Also I look up the source code of Uplink.c which call OPENSSL_Applink() function. Uplink.c use <h=GetModuleHandle(NULL)> to get a handle h, and then use <applink=(void**(*)())GetProcAddress(h,"OPENSSL_Applink")> to got the address of OPENSSL_Applink() . when I use libeay32.dll ,ssleay32.dll in my application , this handle h will point to the application but not my own dll.
So I should add applink.c to my application as a part of my application source code , never add it to my own dll source code.
