How to build
------------
1. cd to a clean directory for building (i.e., don't build in your
source tree)
-2. Make sure Perl is in your PATH. Additionally, some backends may want
- your compile tools in PATH. (Hint: "Visual Studio Command Prompt")
- In the unlikely event that you use -DWITH_MODULES, make sure awk is
- in PATH.
+2. Make sure cmake and Perl are in PATH. Additionally, some backends
+ require compile tools in PATH. (Hint: "Visual Studio Command Prompt")
+ In the unlikely event that you use -DWITH_MODULES, described below, make
+ sure awk is in PATH.
3. cmake -G "some backend, like 'NMake Makefiles'"
-DCMAKE_INSTALL_PREFIX=d:/path/to/httpdinst
-DENABLE_foo=A|I|O|a|i
+ -DENABLE_MODULES=A|I|O|a|i
d:/path/to/httpdsource
Alternately, you can use the cmake-gui and update settings in the GUI.
APR+APR-Util 1.x vs. APR trunk will be detected automatically if they
are installed to the same location as httpd.
+ APR-Util 1.x has an optional LDAP library. If APR-Util has LDAP enabled
+ and httpd's mod_ldap and mod_authnz_ldap are being used, include the
+ path to the LDAP library in the APR_LIBRARIES setting. (If APR and
+ APR-Util are found in the default location, the LDAP library will be
+ included if it is present.
+
LIBXML2_ICONV_INCLUDE_DIR, LIBXML2_ICONV_LIBRARIES
- If using a module that requires libxml2 and the build of libxml2 requires
+ If using a module that requires libxml2 *and* the build of libxml2 requires
iconv, set these variables to allow iconv includes and libraries to be
used. For example:
CMAKE_C_FLAGS_RELEASE, _DEBUG, _RELWITHDEBINFO, _MINSIZEREL
CMAKE_BUILD_TYPE
+
For NMake Makefiles the choices are at least DEBUG, RELEASE,
RELWITHDEBINFO, and MINSIZEREL
Other backends make have other selections.
ENABLE_foo:
+
Each module has a default setting which can be overridden with one of
the following values:
A build and Activate module
Examples: -DENABLE_ACCESS_COMPAT=O
-DENABLE_PROXY_HTML=i
+ ENABLE_MODULES:
+
+ This changes the *minimum* enablement of all modules to the specified
+ value (one of A, a, I, i, O, as described under ENABLE_foo above).
+
+ The ranking of enablement from lowest to highest is O, i, I, a, A.
+ If a specific module has a higher rank enablement setting, either from
+ a built-in default or from -DENABLE_foo, ENABLE_MODULES won't affect
+ that module. However, if a specific module has a lower-rank enablement
+ setting, presumably from a built-in default, the value of ENABLE_MODULES
+ will be used for that module.
+
+ Explanations for possible values:
+
+ -DENABLE_MODULES=a build and activate all possible modules,
+ ignoring any with missing prereqs
+ (doesn't affect modules with A for ENABLE_foo)
+
+ -DENABLE_MODULES=i build but leave inactive all possible
+ modules, ignoring any with missing
+ prereqs
+ (doesn't affect modules with A, a, or I for
+ ENABLE_foo)
+
+ -DENABLE_MODULES=O no impact, since all modules are either
+ already disabled or have a higher setting
+
+ -DENABLE_MODULES=A build and activate all possible modules,
+ failing the build if any module is missing
+ a prereq
+
+ -DENABLE_MODULES=I similar to -DENABLE_MODULES=A
+ (doesn't affect modules with A or a for
+ ENABLE_foo)
+
WITH_MODULES:
- Comma-separated paths to single file modules to statically link into
+
+ Comma-separated paths to single file modules to statically linked into
the server, like the --with-module=modpath:/path/to/mod_foo.c with
the autoconf-based build. Key differences: The modpath (e.g.,
"generators") isn't provided or used, and the copy of the module

EXTRA_INCLUDE_DIRS:
+
List of additional directories to search for .h files. This may
be necessary when including third-party modules in the httpd build
via WITH_MODULES.
- Port and SSLPort: port numbers for substitution into default .conf files.
- (The defaults are 80 and 443.)

+
+ INSTALL_PDB:
+
+ If .pdb files are generated for debugging, install them.
+ Default: ON
+
+ The .pdb files are generally needed for debugging low-level code
+ problems. If they aren't installed, they are still available in the
+ build directory for use by alternate packaging implementations or when
+ debugging on the build machine.
+
+ INSTALL_MANUAL:
+
+ Install the Apache HTTP Server manual.
+ Default: ON
+
+ This could be turned off when developing changes in order to speed up
+ installation time.

+ Makefiles" generator).
Running the server and support programs
---------------------------------------
* no standard script or makefile is provided to tie together the builds
of httpd and support libraries in a manner suitable for typical users
* no logic to find support libraries or otherwise build these modules:
- + mod_socache_dc (distcache), mod_serf (serf)
+ + mod_socache_dc (requires distcache), mod_serf (requires serf)
+ additionally, mod_lbmethod_rr and mod_firehose don't compile on Windows
anyway
* buildmark.c isn't necessarily rebuilt when httpd.exe is regenerated
* ApacheMonitor has a build error and is disabled
* CGI examples aren't installed
+* dbmmanage.pl and wintty aren't built/installed
+* mod_dav.lib and any similar libraries aren't installed, nor are any .exp
+ files (though I'm not sure that is a problem)
* module enablement defaults are not in sync with the autoconf-based build
-* no support for static PCRE builds (need to detect then turn on PCRE_STATIC)
-* module base addresses aren't set
+* no support for static support library builds; unclear if that is a
+ requirement; if so: taking PCRE as an example, we'd need to detect that it
+ is static and then turn on PCRE_STATIC for the libhttpd build
+* program attributes like descriptive name and version aren't set for most
+ binaries
+* build/cpR_noreplace.pl doesn't declare what version of Perl is required
+ and doesn't work with File::Path that is missing make_path
