Platform specific notes:
|
|
------------------------
|
|
|
|
================
|
|
Darwin (OS X):
|
|
Apache 2 relies heavily on the use of autoconf and libtool to
|
|
provide a build environment. Darwin provides these tools as part
|
|
of the Developers Tools package. Under Darwin, however, GNUlibtool
|
|
is installed as 'glibtool' to avoid conflicting with the Darwin
|
|
'libtool' program. Apache 2 knows about this so that's not a
|
|
problem.
|
|
|
|
As of OS X 10.2 (Jaguar), the bundled versions work perfectly. Partly
|
|
this is due to the fact that /bin/sh is now 'bash' and not 'zsh' as
|
|
well as the fact that the bundled versions are up-to-date:
|
|
autoconf 2.52 and (g)libtool 1.4.2.
|
|
|
|
You will note that GNU libtool should actually be installed as
|
|
glibtool, to avoid conflict with a Darwin program of the same
|
|
name.
|
|
|
|
There have been some reports that autoconf 2.52 prevents Apache's
|
|
build system from correctly handling passing multi-value envvars
|
|
to the build system (eg: CFLAGS="-g -O3" ./configure), causing
|
|
errors. Use of bash does not seem to help in this situation. If
|
|
this affects you, downgrading to autoconf 2.13 (which is installed
|
|
on Darwin) will help.
|
|
|
|
With Leopard (at least up to 10.5.2), when running configure
|
|
you will likely see errors such as:
|
|
|
|
rm: conftest.dSYM: is a directory
|
|
|
|
This is a known issue and will be fixed in a later version of the
|
|
autoconf suite. These errors can be safely ignored.
|
|
|
|
For later versions of OS X, (10.8 and 10.9), be sure to have Xcode
|
|
AND Xcode Command Line Tools installed. httpd will built both with
|
|
gcc and clang.
|
|
|
|
==========
|
|
FreeBSD:
|
|
autoconf 2.52 creates scripts that are incompatible with the Posix
|
|
shell implementation (/bin/sh) on FreeBSD. Be sure to use v2.13
|
|
of autoconf.
|
|
|
|
Threaded MPMs are not supported on FreeBSD 4.x. Current releases of
|
|
FreeBSD 5.x (5.2 or later) support threaded MPMs correctly. You must pass
|
|
'--enable-threads=yes' to APR's configure in order to enable threads.
|
|
Additionally, you must use libthr or libkse via libmap.conf as the default
|
|
libc_r is still broken as of this writing. Please consult the man page for
|
|
libmap.conf for more details about configuring libthr or libkse.
|

|
|
HP-UX:
|
|
The dlopen() system call in HP-UX has problems when loading/unloading
|
|
C++ modules. The problem can be resolved by using shl_load() instead
|
|
of dlopen(). This is fixed in the Apache 2.0.44 release.
|
|
To enable loading of C++ modules, the httpd binary has to be linked with
|
|
the following libraries :
|
|
|
|
HP-UX (11.0 / 11i):
|
|
When using shl_load : "cpprt0_stub.s -lcl"
|
|
When using dlopen : "cpprt0_stub.s -lcl -lCsup"
|
|
|
|
HP-UX (11i version 1.5 and greater):
|
|
When using dlopen/shl_load : "cpprt0_stub.s -lcl -lunwind"
|
|
|
|
The cpprt0_stub.s can be downloaded from the web site :
|
|
http://h21007.www2.hp.com/hpux-devtools/CXX/hpux-devtools.0107/0083.html
|
|
|
|
Compile cpprt0_stub.s with the PIC option
|
|
cc -c +z cpprt0_stub.s
|
|
- OR -
|
|
gcc -c -fPIC cpprt0_stub.s
|
|
================
|
|
AIX, using the vendor C compiler with optimization:
|
|
There is an issue with compiling server/core.c with optimization enabled
|
|
which has been seen with C for AIX 5.0.2.3 and above. (5.0.2.0, 5.0.2.1,
|
|
and 5.0.2.2 have an additional problem with Apache 2.0.x, so either upgrade
|
|
the compiler or don't use optimization in order to avoid it.)
|
|
|
|
cc_r works fine with -O2 but xlc_r does not. In order to use xlc_r with
|
|
-O2, apply the patch at
|
|
|
|
http://www.apache.org/dist/httpd/patches/apply_to_2.0.49/aix_xlc_optimization.patch
|
|
|
|
(That patch works with many recent levels of Apache 2+.)
|
|
|
|
================
|
|
Solaris:
|
|
|
|
On Solaris, better performance may be achieved by using the Sun Studio
|
|
compiler instead of gcc. As of version 11, it is now free (registration
|
|
required). Download the compiler from:
|
|
|
|
http://developers.sun.com/prodtech/cc/downloads/index.jsp
|
|
|
|
If you use Sun Studio, the following compiler flags (CFLAGS) are
|
|
recommended:
|
|
|
|
-XO4 -xchip=generic
|
|
|
|
================
|
|
Ubuntu:
|
|
|
|
You will need to ensure that you have either libtool 1.5.6
|
|
or 2.2.6b, or later. Expat 2.0.1 and PCRE 8.02 are also
|
|
recommended to be installed. If building PCRE from source,
|
|
you'll also need g++.
