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.

To build haproxy, you will need :
|
|
- GNU make. Neither Solaris nor OpenBSD's make work with this makefile.
|
|
However, specific Makefiles for BSD and OSX are provided.
|
|
- GCC between 2.91 and 4.3. 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 :
|
|
|
|
- linux22 for Linux 2.2
|
|
- linux24 for Linux 2.4 and above (default)
|
|
- linux24e for Linux 2.4 with support for a working epoll (> 0.21)
|
|
- linux26 for Linux 2.6 and above
|
|
- solaris for Solaris 8 or 10 (others untested)
|
|
- freebsd for FreeBSD 5 to 6.2 (others untested)
|
|
- openbsd for OpenBSD 3.1 to 3.7 (others untested)
|
|
- generic for any other OS.
|
|
- custom to manually adjust every setting
|
|
|
|
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)
|
|
|
|
Alternatively, you may just set the CPU_CFLAGS value to the optimal GCC options
|
|
for your platform.
|
|
|
|
You may want to build specific target binaries which do not match your native
|
|
compiler's target. This is particularly true on 64-bit systems when you want
|
|
to build a 32-bit binary. Use the ARCH variable for this purpose. Right now
|
|
it only knows about a few x86 variants (i386,i486,i586,i686,x86_64) and sets
|
|
-m32/-m64 as well as -march=<arch> accordingly.
|
|
|
|
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 build options for PCRE are :
|
|
|
|
- USE_PCRE=1 to use libpcre, in whatever form is available on your system
|
|
(shared or static)
|
|
|
|
- USE_STATIC_PCRE=1 to use a static version of libpcre even if the dynamic
|
|
one is available. This will enhance portability.
|
|
|
|
- with no option, use your OS libc's standard regex implemntation (default).
|
|
Warning! group references on Solaris seem broken. Use static-pcre whenever
|
|
possible.
|
|
|
|
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 USE_STATIC_PCRE=1
|
|
|
|
And I build it this way on OpenBSD or FreeBSD :
|
|
|
|
$ make -f Makefile.bsd REGEX=pcre DEBUG= COPTS.generic="-Os -fomit-frame-pointer -mgnu"
|
|
|
|
In order to build a 32-bit binary on an x86_64 Linux system :
|
|
|
|
$ make TARGET=linux26 ARCH=i386
|
|
|
|
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 USE_* variables in the GNU Makefile, or ADDINC, ADDLIB, and DEFINE
|
|
variables in the BSD makefiles.
