To build haproxy, you have to choose your target OS amongst the following ones
and assign it to the TARGET variable :
- linux-glibc for Linux kernel 2.6.28 and above
- solaris for Solaris 8 or 10 (others untested)
- freebsd for FreeBSD 5 to 12 (others untested)
- netbsd for NetBSD
- osx for Mac OS/X
- openbsd for OpenBSD 5.7 and above
- aix51 for AIX 5.1
- aix52 for AIX 5.2
- cygwin for Cygwin
- haiku for Haiku
- generic for any other OS or version.
- custom to manually adjust every setting
- linux-glibc for Linux kernel 2.6.28 and above
- linux-glibc-legacy for Linux kernel 2.6.28 and above without new features
- solaris for Solaris 8 or 10 (others untested)
- freebsd for FreeBSD 5 to 12 (others untested)
- netbsd for NetBSD
- osx for Mac OS/X
- openbsd for OpenBSD 5.7 and above
- aix51 for AIX 5.1
- aix52 for AIX 5.2
- cygwin for Cygwin
- haiku for Haiku
- generic for any other OS or version.

You may also choose your CPU to benefit from some optimizations. This is
particularly important on UltraSparc machines. For this, you can assign
