Apache HTTP Server Version 2.0
This document refers to the 2.0 version of Apache httpd, which is no longer maintained. Upgrade, and refer to the current version of httpd instead, documented at:

There are many important points before you begin compiling Apache. See Using Apache with Microsoft Windows before you begin.
Compiling Apache requires the following environment to be properly installed:
Make sure you have at least 50 MB of free disk space available. After installation Apache requires approximately 10 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.
Microsoft Visual C++ 5.0 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
LIB and other variables
that can be configured with the
vcvars32 batch file:
The Windows Platform SDK.
Visual C++ 5.0 builds require an updated Microsoft Windows
Platform SDK to enable some Apache features. For command line
builds, the Platform SDK environment is prepared by the
setenv batch file:
"c:\Program Files\Platform SDK\setenv.bat"
The Platform SDK files distributed with Visual C++ 6.0 and later are sufficient, so users of later version may skip this requirement.
mod_isapifeatures. Without a recent update, Apache will issue warnings under MSVC++ 5.0 that some
mod_isapifeatures will be disabled. Look for the update at http://msdn.microsoft.com/downloads/sdks/platform/platform.asp.
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 generating files. Brian Kernighan's
site has a compiled native Win32 binary,
you must save with the name
awk.exe rather than
awk.exefrom the Tools menu Options... Directories tab (the Projects - VC++ Directories pane in Developer Studio 7.0) listing Executable file paths. Add the path for
awk.exeto this list, and your system
PATHenvironment variable, as needed.
gawk.exeand that the file
awk.exeis really a symlink to the
gawk.exefile. The Windows command shell does not recognize symlinks, and because of that building InstallBin will fail. A workaround is to delete
awk.exefrom the cygwin installation and rename
[Optional] OpenSSL libraries (for
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
or the abs project (
ab.exe with SSL support.) To prepare OpenSSL
debug builds of Apache, and
disable the patent protected features in OpenSSL, you might use the following
perl Configure VC-WIN32
perl util\mkfiles.pl >MINFO
perl util\mk1mf.pl dll no-asm no-mdc2 no-rc5 no-idea VC-WIN32 >makefile.rel
perl util\mk1mf.pl dll debug no-asm no-mdc2 no-rc5 no-idea VC-WIN32 >makefile.dbg

perl util\mkdef.pl 32 ssleay no-asm no-mdc2 no-rc5 no-idea >ms\ssleay32.def
nmake -f makefile.rel
nmake -f makefile.dbg
Note; you can use the scripts in the
ms\ subdirectory, however,
it's rather tricky to force
ms\do_masm.bat, for example, to perform
the patent encumberances as mentioned above. Patches to add the $* argument list
to the appropriate .bat lines in these scripts aren't incorporated, thus far.
[Optional] zlib sources (for
Zlib must be installed into a
srclib subdirectory named
zlib, however those sources need not be compiled. The build system
will compile the compression sources directly into the
module. Zlib can be obtained from http://www.zlib.net/ --
mod_deflate is confirmed to build
correctly with version 1.1.4. To use a later version of zlib, upgrade to
Apache HTTP Server release 2.2 or later.
First, unpack the Apache distribution into an appropriate
directory. Open a command-line prompt and
cd to that
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
debug build, respectively:
nmake /f Makefile.win _apacher nmake /f Makefile.win _apached
Either command will compile Apache. The latter will include debugging information in the resulting files, making it easier to find bugs and track down problems.
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
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.

InstallBin causes all

INSTDIR= choice by changing
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.
.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

Build the entire project from within the VC++ 5.0 or 6.0 IDE,
then use the Project Menu Export for all makefiles.
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:
You must type this command from the top level
directory of the httpd source tree. Every
.dep project file within
the current directory and below will be corrected, and the
timestamps adjusted to reflect the
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.
Apache.dsw workspace and
nmake script both build the

In addition, the
modules\ subdirectory tree contains
project files for the majority of the modules.
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
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 /f Makefile.win installr INSTDIR=dir nmake /f Makefile.win installd INSTDIR=dir
The dir argument to
the installation directory; it can be omitted if Apache is
to be installed into
This will install the following:
dir\bin\Apache.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\libaprutil.dll- Apache Utility Runtime shared library
dir\bin\libhttpd.dll- Apache Core library

dir\conf- Configuration directory
dir\logs- Empty logging directory
dir\include- C language header files
dir\lib- Link library files
