Hank A. Paulson suggested to add CPU=native to optimize the code for
the build machine. This makes sense in a lot of situations. Since it
is often possible to have both 32 and 64 bits supported on recent
systems, the ARCH=32 and ARCH=64 build options were also added.
Patrick Mézard reported that it was a bit awkward to have the CONTRIB
and contrib entries in the source archive since those can conflict on
case-insensitive file systems. That made a good opportunity to refresh
the README file and to remove that old outdated file.
After considering various possibilities, we compiled haproxy under cygwin.
Attached is an updated full diff that also has the TARGET=cygwin documented.
The whole thing compiles and installs with this diff only.
In cygwin 1.7 (now in beta), there is apparently support for ipv6. Cygwin
1.5 (later versions, anyway) already includes some support in the form of a
define USE_IPV6. When defined, it declares the sockaddr_in6 struct and
possibly other things. The above definition AF_INET6=23 is taken from
their /usr/include/socket.h file (where it is #if 0'd out).
We are running into a socket limit. It appears that Cygwin (running on
Windows 2003 Server) will only allow us to set ulimit -n (maximum open
files) to 3200, which means we're a little short of 1600 connections.
The limit of 3200 is an internal Cygwin limit. Perhaps they can raise it in
the future. Using the nbproc option, I was able to bring up 10 servers. It
seems to me that they were able to handle over 2000 connections (even though
each had maxconn 1500 set, and the hard Cygwin fd limit).
When trying to build a 32-bit binary on a 64-bit platform, we generally
need to pass "-m32" to gcc, which is not convenient with current makefile.
Note that this option requires gcc >= 3.
In order to ease parameter passing, a new ARCH= makefile option has been
added. If it receives a target architecture, according "-m32"/"-m64" and
"-march=xxxx" will be passed to gcc. Only the generic makefile has been
changed to support this option right now as the need only appeared on Linux.
The spec file now makes use of this option so that rpmbuild can automatically
build with the proper architecture.
