How To Build libcurl to Use ares For Asynch Name Resolves
|
|
=========================================================
|
|
|
|
ares:
|
|
ftp://athena-dist.mit.edu/pub/ATHENA/ares/ares-1.1.1.tar.gz
|
|
http://curl.haxx.se/dev/ares-1.1.1.tar.gz

|
c-ares: (a patched and improved version of ares)
|
|
http://curl.haxx.se/beta/arescurl-1.0-pre1.tar.gz
|
|
|
|
NOTE
|
|
libcurl works with ares 1.1.1, but several patches and improvements have
|
|
been put into the c-ares package which has made it more portable and better
|
|
working on several platforms.

|
|
Build ares
|
|
==========
|
|
|
|
1. unpack the ares archive
|
|
2. cd ares-dir
|
|
3. ./configure
|
|
4. make
|
|
|
|
Build libcurl to use ares in the curl source tree
|
|
=================================================
|
|
|
|
1. name the ares source directory 'ares' in the curl source directory
|
|
2. ./configure --enable-ares
|
|
3. make
|
|
|
|
Build libcurl to use an installed ares
|
|
======================================
|
|
|
|
1. ./configure --enable-ares=/path/to/ares/install
|
|
2. make
|
|
|
|
Ares and ipv6
|
|
=============
|
|
|
|
If the configure script enables IPv6 support you need to explicitly disable
|
|
that (--disable-ipv6) since ares isn't IPv6 compatible (yet).

Ares on win32
|
|
=============
|
|
(description brought by Dominick Meglio)
|
|
|
|
First I compiled curl-ares. I changed the default C runtime library to be the
|
|
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 added was, near the HAVE_GETTIMEOFDAY checks I added:
|
|
#ifdef USE_ARES
|
|
#define HAVE_GETTIMEOFDAY 1
|
|
#endif
|
|
|
|
The reason is, it seems curl-ares has a gettimeofday function in it (perhaps
|
|
this should be made static in ares to avoid this kludge?) To prevent a
|
|
duplicate symbol error, I had to make sure libcurl didn't also try and create
|
|
a gettimeofday() function.
|
|
|
|
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.
