| 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 |
| http://curl.sourceforge.net/dev/ares-1.1.1.tar.gz |
| http://curl.planetmirror.com/dev/ares-1.1.1.tar.gz |
| http://curl.tsuren.net/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 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. |
