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++. |
