Compiling Apache requires the following environment to be
properly installed:
-
Disk Space
Make sure you have at least 180 MB of free disk space
available. After installation Apache requires approximately
70 MB of disk space, plus space for log and cache files,
which can grow rapidly. The actual disk space requirements
will vary considerably based on your chosen configuration and
any third-party modules or libraries, especially when OpenSSL
is also built. Because many files are text and very easily
compressed, NTFS filesystem compression cuts these requirements
in half.
-
Microsoft Visual C++ (Microsoft Visual Studio) 6.0 or higher.
Apache can be built using the command line tools, or from
within the Visual Studio IDE Workbench. The command line
build requires the environment to reflect the PATH,
INCLUDE, LIB and other variables
that can be configured with the vcvars32.bat file:
"c:\Program Files\Microsoft Visual Studio\VC98\Bin\VCVARS32"
-
The Windows Platform SDK for Visual C++ 6.0 (97) or 7.0 (.NET)
Apache's APR and APR-util builds require an updated Microsoft
Windows Platform SDK, from Feb 2003 or later, included in the
Visual C++ 7.1 (Studio 2003) and later. For command line builds with
Visual C++ 6.0 or 7.0, the Platform SDK environment is prepared by
the setenv.bat file:
"c:\Program Files\Platform SDK\setenv.bat"
The Platform SDK files distributed with Visual C++ 6.0 and
Visual Studio .NET (2000) are no longer sufficient and cause many
compilation warnings and linkage errors. Users of Visual C++ 7.1
(Studio 2003) and later versions (of the full product, not the
'Visual Studio Express' flavor) may skip this requirement.
If using the GUI, either start msdev or devenv with the /setenv
flag (after invoking setenv.bat), or ensure the paths are correct
under the Tools -> Options -> (Projects ->) Directories
menu option. The Platform SDK installer will generally help you
configure this.
-
The awk utility (awk, gawk or similar).
To install Apache within the build system, several files are
modified using the awk.exe utility. awk was chosen since
it is a very small download (compared with Perl or WSH/VB) and
accomplishes the task of modifying configuration files upon
installation. Brian Kernighan's
http://cm.bell-labs.com/cm/cs/who/bwk/
site has a compiled native Win32 binary,
http://cm.bell-labs.com/cm/cs/who/bwk/awk95.exe which
you must save with the name awk.exe rather than
awk95.exe.
If awk.exe is not found, Makefile.win's install target
will not perform substitutions in the installed .conf files.
The installed .conf files must then be modified by hand for
this situation.
Note that Developer Studio IDE will only find
awk.exe from the Executable path specified in the menu
option Tools -> Options -> (Projects ->) Directories.
Add the path for awk.exe to this list, and your
system PATH environment variable, as needed.
Also note that if you are using Cygwin tools
(
http://www.cygwin.com/)
the awk utility is named
gawk.exe and that the file
awk.exe is really a symlink to the
gawk.exe
file. The Windows command shell does not recognize symlinks, and
because of this building InstallBin will fail. A workaround is
to delete
awk.exe from the cygwin installation and
copy
gawk.exe to
awk.exe. Also note the
cygwin/mingw ports of gawk 3.0.x were buggy, please upgrade to 3.1.x
before attempting to use any gawk port.
-
[Optional] zlib library (for mod_deflate)
Zlib must be installed into a srclib subdirectory named
zlib. This must be built in-place. Zlib can be obtained
from http://www.zlib.net/ -- the
mod_deflate is confirmed to work correctly with
version 1.2.3.
nmake -f win32\Makefile.msc
nmake -f win32\Makefile.msc test
-
[Optional] OpenSSL libraries (for mod_ssl
and ab.exe with ssl support)
Caution: there are significant restrictions and
prohibitions on the use and distribution of strong cryptography
and patented intellectual property throughout the world.
OpenSSL includes strong cryptography controlled by both export
regulations and domestic law, as well as intellectual property
protected by patent, in the United States and elsewhere. Neither
the Apache Software Foundation nor the OpenSSL project can provide
legal advise regarding possession, use, or distribution of the code
provided by the OpenSSL project. Consult your own legal
counsel, you are responsible for your own actions.
OpenSSL must be installed into a srclib subdirectory
named openssl, obtained from
http://www.openssl.org/source/, in order to compile
mod_ssl or the abs project (ab.exe
enabled with SSL support.) To prepare OpenSSL for both
release and debug builds of Apache, and
disable the patent protected features in OpenSSL, you might use
the following build commands:
perl Configure no-mdc2 no-rc5 no-idea enable-zlib VC-WIN32 -Ipath/to/srclib/zlib
ms\do_masm.bat
nmake -f ms\ntdll.mak
Note: It is not advisable to use zlib-dynamic, as that could
pose a thread race condition. If building zlib on win32, be sure
to adjust the resulting ms\ntdll.mak file to link to the full
path of srclib\zlib\zdll.lib rather than zlib1.lib (that error in
configuration of OpenSSL through 0.9.8h and earlier reflects older
zlib 1.1 versions.)

First, unpack the Apache distribution into an appropriate
directory. Open a command-line prompt and cd to that
directory.
The master Apache makefile instructions are contained in the
Makefile.win file. To compile Apache on Windows
NT, simply use one of the following commands to compiled the
release or debug build, respectively:
nmake /f Makefile.win _apacher
nmake /f Makefile.win _apached
Either command will compile Apache. The latter will disable
optimization of the resulting files, making it easier to single
step the code to find bugs and track down problems.
You can add your apr-util dbd provider choices with the additional
make variable DBD_LIST, e.g. DBD_LIST="mysql oracle pgsql sqlite3"
to build these four providers. However it's necessary to have
the include headers in the INCLUDE path list, db client libraries
in the LIB path list, and the db client dll files in the PATH. The
specifics for each provider are an exercise left to the reader.

Apache can also be compiled using VC++'s Visual Studio
development environment. To simplify this process, a
Visual Studio workspace, Apache.dsw, is provided.
This workspace exposes the entire list of working .dsp
projects that are required for the complete Apache binary release.
It includes dependencies between the projects to assure that they
are built in the appropriate order.
Open the Apache.dsw workspace, and select
InstallBin (Release or Debug build,
as desired) as the Active Project. InstallBin causes all
related project to be built, and then invokes Makefile.win to
move the compiled executables and dlls. You may personalize the
INSTDIR= choice by changing InstallBin's Settings,
General tab, Build command line entry. INSTDIR defaults to the
/Apache2 directory. If you only want a test compile (without
installing) you may build the BuildBin project instead.
The .dsp project files are distributed in Visual
C++ 6.0 format. Visual C++ 5.0 (97) will recognize them. Visual C++
7.0 (.net) must convert Apache.dsw plus the .dsp
files into an Apache.sln plus .msproj files,
be sure you reconvert the .msproj file if any of the source
.dsp files change! This is really trivial, just open
Apache.dsw in the VC++ 7.0 IDE once again.
There is a flaw in the .vcproj conversion of .dsp through
Visual Studio 2005 SP1; devenv.exe will mis-parse the /D flag for RC
flags containing long quoted /D'efines containing spaces. The command:
perl srclib\apr\build\cvtdsp.pl -2005
will convert the /D flags for RC flags to use an alternate, parseable
syntax; unfortunately this syntax isn't supported by Visual Studio 97
or it's exported .mak files. These /D flags are used to pass the long
description of the mod_apachemodule.so files to their .rc resource
version-identifier compilations, and replace the use of awk for generating
.rc files formerly used for Apache 2.0.
Visual C++ 7.0 (.net) users should also use the Build
menu, Configuration Manager dialog to uncheck both the Debug
and Release Solution modules abs, mod_ssl
and mod_deflate.
These modules are built by invoking nmake or the IDE directly
with the BinBuild target to build those modules conditionally
if the srclib directories openssl and/or
zlib exist.
Exported
.mak files pose a greater hassle, but they are
required for Visual C++ 5.0 users to build
mod_ssl,
abs (
ab with SSL support) and/or
mod_deflate. VC++ 7.0 (Visual Studio .NET) users
also benefit,
nmake builds were faster than
binenv builds until the parallel compilation features
introduced in Visual Studio 2005. Build the entire project from within
the VC++ 5.0 or 6.0 IDE, preferably with mod_deflate, mod_ssl and abs,
then use the Project Menu Export for all makefiles (preferably, with
dependencies.) You must build the projects first in order to create
all dynamic auto-generated targets, so that dependencies can be parsed
correctly. Run the following command to fix the paths so they will build
anywhere:
perl srclib\apr\build\fixwin32mak.pl
You must type this command from the top level
directory of the httpd source tree. Every
.mak and .dep project file within
the current directory and below will be corrected, and the
timestamps adjusted to reflect the .dsp.
If you contribute back a patch that revises project files, we
must commit project files in Visual Studio 6.0 format. Changes
should be simple, with minimal compilation and linkage flags that
will be recognized by all VC++ 5.0 through 7.0 environments.

The Apache.dsw workspace and makefile.win
nmake script both build the .dsp projects
of the Apache server in the following sequence:
srclib\apr\apr.dsp
srclib\apr\libapr.dsp
srclib\apr-util\uri\gen_uri_delims.dsp
srclib\apr-util\xml\expat\lib\xml.dsp
srclib\apr-util\aprutil.dsp
srclib\apr-util\libaprutil.dsp
srclib\pcre\dftables.dsp
srclib\pcre\pcre.dsp
srclib\pcre\pcreposix.dsp
server\gen_test_char.dsp
libhttpd.dsp
Apache.dsp
In addition, the modules\ subdirectory tree contains
project files for the majority of the modules.
The support\ directory contains project files for
additional programs that are not part of the Apache runtime,
but are used by the administrator to test Apache and maintain
password and log files. Windows-specific support projects are
broken out in the support\win32\ directory.
support\ab.dsp
support\htdigest.dsp
support\htpasswd.dsp
support\logresolve.dsp
support\rotatelogs.dsp
support\win32\ApacheMonitor.dsp
support\win32\wintty.dsp
Once Apache has been compiled, it needs to be installed in
its server root directory. The default is the
\Apache2 directory, of the same drive.
To build and install all the files into the desired folder
dir automatically, use one of the following
nmake commands:
nmake /f Makefile.win installr INSTDIR=dir
nmake /f Makefile.win installd INSTDIR=dir
The dir argument to INSTDIR gives
the installation directory; it can be omitted if Apache is
to be installed into \Apache2.
This will install the following:
dir\bin\httpd.exe - Apache
executable
dir\bin\ApacheMonitor.exe - Service
monitor taskbar icon utility
dir\bin\htdigest.exe - Digest auth
password file utility
dir\bin\htdbm.exe - SDBM auth
database password file utility
dir\bin\htpasswd.exe - Basic auth
password file utility
dir\bin\logresolve.exe - Log file
dns name lookup utility
dir\bin\rotatelogs.exe - Log file
cycling utility
dir\bin\wintty.exe - Console window
utility
dir\bin\libapr.dll - Apache
Portable Runtime shared library
dir\bin\libaprutil.dll - Apache
Utility Runtime shared library
dir\bin\libhttpd.dll - Apache Core
library
dir\modules\mod_*.so - Loadable
Apache modules
dir\conf - Configuration
directory
dir\logs - Empty logging
directory
dir\include - C language header
files
dir\lib - Link library files
Note only the .dsp files are maintained between release
builds. The .mak files are NOT regenerated, due to the tremendous
waste of reviewer's time. Therefore, you cannot rely on the NMAKE
commands above to build revised .dsp project files unless you
then export all .mak files yourself from the project. This is
unnecessary if you build from within the Microsoft
Developer Studio environment.
Also note it is very worthwhile to build the BuildBin
target project (or the command line _apacher or
_apached target) prior to exporting the make files.
Many files are autogenerated in the build process. Only a full
build provides all of the dependent files required to build proper
dependency trees for correct build behavior.
In order to create distribution .mak files, always
review the generated .mak (or .dep)
dependencies for Platform SDK or other garbage, machine specific
includes. The DevStudio\SharedIDE\bin\ (VC5) or
DevStudio\Common\MSDev98\bin\ (VC6) directory contains
the sysincl.dat file, which must list all exceptions.
Update this file (including both forward and backslashed paths, such
as both sys/time.h and sys\time.h) to ignore
such dependencies. Including local-install paths in a distributed
.mak file will cause the build to fail completely. And
don't forget to run srclib/apr/build/fixwin32mak.pl in
order to fix absolute paths within the .mak files.
