To build haproxy, you will need :
|
||
|
|
- GNU make. Neither Solaris nor OpenBSD's make work with this makefile.
|
||
|
|
- GCC between 2.91 and 3.4. Others may work, but not tested.
|
||
|
|
- GNU ld
|
||
|
|
|
||
|
|
Also, you might want to build with libpcre support, which will provide a very
|
||
|
|
efficient regex implementation and will also fix some badness on Solaris's one.
|
||
|
|
|
||
|
|
To build haproxy, you have to choose your target OS amongst the following ones
|
||
|
|
and assign it to the TARGET variable :
|
||
|
|
|
||
|
|
- linux24 for Linux 2.4 and above (default)
|
||
|
|
- linux24e for Linux 2.4 with support for epoll
|
||
|
|
- linux26 for Linux 2.6 and above
|
||
|
|
- linux22 for Linux 2.2
|
||
|
|
- solaris for Solaris 8 or 10 (others untested)
|
||
|
|
- openbsd for OpenBSD 3.1 to 3.7 (others untested)
|
||
|
|
- generic for any other OS.
|
||
|
|
|
||
|
|
You may also choose your CPU to benefit from some optimizations. This is
|
||
|
|
particularly important on UltraSparc machines. For this, you can assign
|
||
|
|
one of the following choices to the CPU variable :
|
||
|
|
|
||
|
|
- i686 for intel PentiumPro, Pentium 2 and above, AMD Athlon
|
||
|
|
- i586 for intel Pentium, AMD K6, VIA C3.
|
||
|
|
- ultrasparc : Sun UltraSparc I/II/III/IV processor
|
||
|
|
- generic : any other processor or no specific optimization. (default)
|
||
|
|
|
||
|
|
If your system supports PCRE (Perl Compatible Regular Expressions), then you
|
||
|
|
really should build with libpcre which is between 2 and 10 times faster than
|
||
|
|
other libc implementations. Regex are used for header processing (deletion,
|
||
|
|
rewriting, allow, deny). The only inconvenient of libpcre is that it is not
|
||
|
|
yet widely spread, so if you build for other systems, you might get into
|
||
|
|
trouble if they don't have the dynamic library. In this situation, you should
|
||
|
|
statically link libpcre into haproxy so that it will not be necessary to
|
||
|
|
install it on target systems. Available options for the REGEX variable are :
|
||
|
|
|
||
|
|
- libc to use your OS libc's standard regex implemntation (default).
|
||
|
|
Warning! group references on Solaris seem broken. Use static-pcre whenever
|
||
|
|
possible.
|
||
|
|
|
||
|
|
- pcre to use libpcre, in whatever form it is available on your system
|
||
|
|
(shared or static)
|
||
|
|
|
||
|
|
- static-pcre to use a static version of libpcre even if the dynamic one is
|
||
|
|
available. This will enhance portability.
|
||
|
|
|
||
|
|
By default, the DEBUG variable is set to '-g' to enable debug symbols. It is
|
||
|
|
not wise to disable it on uncommon systems, because it's often the only way to
|
||
|
|
get a complete core when you need one. Otherwise, you can set DEBUG to '-s' to
|
||
|
|
strip the binary.
|
||
|
|
|
||
|
|
For example, I use this to build for Solaris 8 :
|
||
|
|
|
||
|
|
$ make TARGET=solaris CPU=ultrasparc REGEX=static-pcre
|
||
|
|
|
||
|
|
If you need to pass other defines, includes, libraries, etc... then please
|
||
|
|
check the Makefile to see which ones will be available in your case, and
|
||
|
|
use the ADDINC, ADDLIB, and DEFINE variables for this.
|
||
|
|
|
||
