Unable to compile on Windows using cyassl.lib

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download latest cyassl source and compile
2. Modify Makefile to provide the correct cyassl.lib location
3. On Windows using MSVS 2010, execute nmake windows

What is the expected output? What do you see instead?
I should get a proper compiled binary, mongoose.exe. I am getting unresolved 
external symbols. I have also compiled "cyassl.lib" from source and specified 
the correct location in the Makefile. Are you not using cyassl.lib or perhaps a 
different version?? Where can I find that?

What version of the product are you using? On what operating system?
Compiling from code, Windows XP using MSVS 2010

Please provide any additional information below.
I get the following unresolved external symbol errors:

Makefile is written for Visual Studio 6.
Sorry, I have no time and resources to deal with other versions of the compiler.

These are not Visual Studio 10 related errors. What I see is library linking 
errors which generally occur because the cyassl.lib library that I am linking 
when building mongoose.c is missing the symbols that are referenced. Your SVN 
only contains the source for mongoose.c and mongoose.h and not for the ssl 
library. But, I did find any mention for the correct version of 'cyassl.lib' to 
use in the Makefile. I am not requesting you to fix your Makefile to work with 
Visual Studio 10. I am only requesting you to fix it so that it compiles 
against the current source of 'cyassl.lib' or provide the cyassl.lib's source 
along with mongoose.

I am having this same problem

Did you ever find a workaround?

Original comment by scootere...@gmail.com on 7 Jul 2011 at 9:11

[GoogleCodeExporter]

You should build cyassl.lib yourself from the sources provided by 
http://yassl.com,
http://yassl.com/yaSSL/Products-cyassl.html

Yes, that's exactly what I did. It appears that the only sources available 
there are newer than the ones that mongoose was written against at least for 
windows.

I still haven't found a solution, compiled without SSL and using that. I 
requested author to share his cyassl sources or update mongoose to use the 
latest, but it seems like he has no time to do that. 
Doesn't that render this project useless? I want to embed a webserver in my 
application with SSL, but cannot. Sure, I can use the compiled sources to run a 
separate webserver but I find Apache or Lighthttpd much more efficient for that 
purposes.

OK thanks for the tip about compiling without SSL support as a workaround, 
though I agree with you, SSL is pretty important.

Note: I had to change the /Gz link flag to /Gd for the mongoose symbols to be 
exported properly.

Original comment by scootere...@gmail.com on 8 Jul 2011 at 8:34

[GoogleCodeExporter]

oops, /Gz and /Gd are compiler options, not linker options

So are there any plans to support the latest yassl api so we can use mongoose 
with SSL on windows?

I've downloaded current cyassl sources cyassl-2.0.0rc2, and modified Makefile 
to work with them.
See 
https://code.google.com/p/mongoose/source/detail?r=bfd15b3ac9d8adebedada8b212c31
5b89a491724 for details.

Build looks like this: modify Makefile to point to where cyassl sources are 
extracted (don't build though), then:
del *.obj
nmake cyassl
nmake windows

Let me know if you have any troubles.

Hi, I was able to get this to compile with VS 2008 (9.0), with the following 
gyrations.

I downloaded cyassl-2.0.0rc2 and added it to the mongoose folder under C:\ like 
so:

c:\mongoose-3.0

10/09/2011  09:59 PM    <DIR>          cyassl-2.0.0rc2
10/09/2011  09:59 PM    <DIR>          mongoose

I did not compile cyassl using their provided VS solution. I used the Visual 
Studio 2008 Command Prompt (gets your nmake.exe paths, etc).

The biggie was I had to make the following modifications to the Makefile to get 
rid of the external resolution errors, which included adding a couple missing 
.c files to CYASRC. Also, I had to change the forward slashes to a backslash to 
make the compiler happy.

Here's a diff of my Makefile  vs. the one downloaded in the mongoose source:
