NOTE

|
|
|
The latest libcurl version requires c-ares 1.4.0 or later.
|

|
|
|
|
|
|
|
Once upon the time libcurl built fine with the "original" ares. That is no
|
2006-11-03 18:56:37 +08:00
|
|
|
longer true. You need to use c-ares.

Build c-ares
|
|
|
|
============

|
|
|
|
2004-04-06 15:59:11 +08:00
|
|
|
1. unpack the c-ares archive
|
|
|
|
2. cd c-ares-dir
|
2003-10-13 21:07:50 +08:00
|
|
|
3. ./configure
|
|
|
|
4. make

Build libcurl to use c-ares in the curl source tree
|

|
|
|
|
2010-03-24 17:44:25 +08:00
|
|
|
1. name or symlink the c-ares source directory 'ares' in the curl source
|
|
|
|
directory
|
2003-10-13 21:07:50 +08:00
|
|
|
2. ./configure --enable-ares
|
2010-03-24 17:44:25 +08:00
|
|
|
|
|
|
|
Optionally, you can point out the c-ares install tree root with the the
|
|
|
|
--enable-ares option.

|
|
First I compiled c-ares. I changed the default C runtime library to be the
|
2004-01-04 20:00:11 +08:00
|
|
|
single-threaded rather than the multi-threaded (this seems to be required to
|
|
|
|
prevent linking errors later on). Then I simply build the areslib project (the
|
|
|
|
other projects adig/ahost seem to fail under MSVC).
|
|
|
|
|
|
|
|
Next was libcurl. I opened lib/config-win32.h and I added a:
|
|
|
|
#define USE_ARES 1
|
|
|
|
|
|
|
|
Next thing I did was I added the path for the ares includes to the include
|
|
|
|
path, and the libares.lib to the libraries.
|
|
|
|
|
|
|
|
Lastly, I also changed libcurl to be single-threaded rather than
|
|
|
|
multi-threaded, again this was to prevent some duplicate symbol errors. I'm
|
|
|
|
not sure why I needed to change everything to single-threaded, but when I
|
|
|
|
didn't I got redefinition errors for several CRT functions (malloc, stricmp,
|
|
|
|
etc.)
|
|
|
|
|
|
|
|
I would have modified the MSVC++ project files, but I only have VC.NET and it
|
|
|
|
uses a different format than VC6.0 so I didn't want to go and change
|
|
|
|
everything and remove VC6.0 support from libcurl.
