Hello,

I'm trying to create a version of libcurl.lib that I can include statically
in a Windows program I'm writing. My end goal is to have all the
libcurl+ssl+zlib functionality inside my Windows executable, so if there is
an alternate way to accomplish what I'm thinking, I am open to suggestions.
I am trying hard not to have accompanying dll files in my setup
distribution. A precompiled working static libcurl.lib binary with
up-to-date ssl+zlib functionality would be ideal, though I have not been
able to find exactly that using a Google search, as each of the various
hosted binaries seem to be incomplete or deficient in some way.

So far I seem to have compiled the libcurl.lib successfully. When I try to
link it inside my windows executable, a number of errors fire off. It looks
like all the errors are related to ssl functions.

This is the process I went through to create my libcurl.lib. First I
downloaded the curl-7.17.1 source package. Then I downloaded openssl-0.9.8g.
I put both of these directories at the root of the C: drive. To compile
openssl I followed the direction in INSTALL.W32. First I installed
ActivePerl. Then I loaded up a prompt, and from the
C:\openssl-0.9.8gdirectory I ran

> perl Configure VC-WIN32 --prefix=c:/openssl
> ms\do_masm
>nmake -f ms\nt.mak
>nmake -f ms\nt.mak test
>nmake -f ms\nt.mak install
[note nt.mak and not ntdll.mak, for the static version]

Everything appeared to run fine without complaint. Both libeay32.lib and
ssleay32.lib showed up in C:\openssl-0.9.8g\out32.

Then I followed the Win32->'MSVC from command line' instructions in
libcurl's INSTALL file. I ran my corresponding vcvars32.bat, and set my path
using set OPENSSL_PATH=c:\openssl-0.9.8g (Note my 'g' where the help file
has 'e'. Also, I would later try this with a forward slash, as the output at
the end of the compile process has mismatching slashes. The version shown is
taken directly from the INSTALL file.) Then I ran 'nmake vc' and 'nmake
vc-ssl'.

The end of that output looks something like this (I have run it multiple
times, and it appears to change each time. This is what it looks like
currently.) :

        link.exe /incremental:no /libpath:"../lib" /nologo /out:curl.exe/subsys
tem:console /machine:X86 /LIBPATH:"c:/openssl-0.9.8g/out32" libcurl.lib
libeay3
2.lib ssleay32.lib gdi32.lib user32.lib advapi32.lib wsock32.lib wldap32.libwin
mm.lib hugehelpr.obj writeoutr.obj urlglobr.obj getpassr.obj
homedirr.obj c
urlutilr.obj strtoofftr.obj mainr.obj curlr.res

I then copy the libcurl.lib file from C:\curl-7.17.1\lib\release-ssl to the
root directory of my windows project. I have it set to include
libcurl.liband ws2_32.lib in Project->Properties->Configuration
Properties->Linker->Input : Additional Dependencies.

I also have C:\curl-7.17.1\include listed in my 'Additional Include'
directories. At the beginning of the source file I have

#include <curl/curl.h>

and I have variously defined CURL_STATICLIB using

 #define CURL_STATICLIB

at the beginning of the source file and

-DCURL_STATICLIB

as a command-line option. This command line option is present in the
C/C++->Command Line settings and not in the Linker->Command Line settings.

The errors I get are as follows:
