I have noted the instructions on how to build the HTTPD web server from scratch in a Cygwin platoform in a Windows 7 PC.

Note that compiling full HTTPD on Cygwin is very slow compare to other system such as Linux or MacOSX! If you are looking to do full HTTPD server development, it’s recommend to use a real Linux env instead.

Requirements:

• Apache HTTPD version 2.4.9

• CYGWIN\_NT-6.1 L328BDS002096US 2.10.0(0.325/5/3) 2018-02-02 15:16 x86\_64 Cygwin

• Install the following cygwin packages:

          autoconf
          make
          automake
          m4
          gcc-core
          libtool
          bison
          flex
          perl
          libapr1-devel
          libaprutil1-devel
          libiconv-devel
          libpcre-devel
          libgdbm-devel
          openssl-devel
  

Compiling the server

Step 1. Get the source:

git clone git://git.apache.org/httpd.git
cd httpd
git checkout 2.4.9

# You also need to get the required library sources
cd srclib
git clone git://git.apache.org/apr.git
cd apr
git checkout 1.6.3
cd ../
git clone git://git.apache.org/apr-util.git
cd apr-util
git checkout 1.6.1
cd ../../

Note that unlike the source pre-package you download from Apache site, the httpd source repo does not have configure script, and you need to generate it with buildconf. See next step for further instruction.

Note that the current apr-util repository is empty in master branch! This is because they moved the code to apr starting version 2.0 dev, but we still be using version 1.6.x, so we need to explicitly checkout the tag or branch.

Step 2. Compiling

./buildconf
./configure --prefix=/usr/local/apache2 \
  --with-included-apr \
  --enable-mpms-shared \
  --with-mpm=worker \
  --enable-mods-shared=most
make
make install

The option --prefix=/usr/local/apache2 tells the build to install the software into a user specific location.

The option enable-mpms-shared will make the mpm_module to be shared library so you can switch to different threading model if you want. Default to worker which should work nicely in Cygwin env.

The option enable-mods-shared will make most of the modules as shared libraries. You can use all for full server.

The option --with-included-apr tells the build to use the srclib/apr we have downloaded. Here you can use system installed apr if you like. For an example:

./configure --prefix=/usr/local/apache2 \
--with-apr=/usr/bin/apr-1-config \
--with-apr-util=/usr/bin/apu-1-config \
--enable-mpms-shared \
--with-mpm=worker \
--enable-mods-shared=most
