+ 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.
+
+ Earlier versions of OS X are not so fortunate, and the bundled tools
+ are not only older versions, but also, for the most part, do not work
well. If you are interested in developing under Darwin, we
recommend that you obtain and install replacement versions of what
- are normally installed on Darwin (and OS X, as of v10.1.4). If
+ are normally installed on Darwin (and OS X, as of v10.1.5). If
you build your own versions of autoconf 2.52 and libtool 1.4.2, be
aware that there are some Darwin specific patches to the official
code that still must be applied for them to fully work. A useful
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.
+
+ With Darwin 10, the default C compiler (gcc) will try to build
+ multi-architecture bundles. This causes problems with APR, which
+ needs to know various data-type sizes which it assumes are universal
+ for platforms. Until this is fully fixed, we recommend using the
+ '-arch i386' gcc option when building both Apache and APR.

==========
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++.
