Experimental cmake-based build support for APR-Util on Microsoft Windows
|
|
|
|
Status
|
|
------
|
|
|
|
This build support is currently intended only for Microsoft Windows.
|
|
Only Windows NT-based systems can be targeted. (The traditional
|
|
Windows build support for APR can target Windows 9x as well.)
|
|
|
|
This build support is experimental. Specifically,
|
|
|
|
* It does not support all features of APR-Util.
|
|
* Some components may not be built correctly and/or in a manner
|
|
compatible with the previous Windows build support.
|
|
* Build interfaces, such as the mechanisms which are used to enable
|
|
optional functionality or specify prerequisites, may change from
|
|
release to release as feedback is received from users and bugs and
|
|
limitations are resolved.
|
|
|
|
Important: Refer to the "Known Bugs and Limitations" section for further
|
|
information.
|
|
|
|
It is beyond the scope of this document to document or explain
|
|
how to utilize the various cmake features, such as different
|
|
build backends or provisions for finding support libraries.
|
|
|
|
Please refer to the cmake documentation for additional information
|
|
that applies to building any project with cmake.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
The following tools must be in PATH:
|
|
|
|
* cmake, version 2.8 or later
|
|
cmake version 3.1.3 or later is required to work with current OpenSSL
|
|
releases. (OpenSSL is an optional prerequisite of APR-Util.)
|
|
* If using a command-line compiler: compiler and linker and related tools
|
|
(Refer to the cmake documentation for more information.)
|
|
|
|
The following support libraries are mandatory:
|
|
|
|
* APR 1.4.x or APR 1.5.x, built with cmake
|
|
|
|
Optional support libraries allow optional features of APR to be enabled:
|
|
|
|
* OpenSSL
|
|
* many others potentially, though the build support isn't currently
|
|
implemented
|
|
|
|
How to build
|
|
------------
|
|
|
|
1. cd to a clean directory for building (i.e., don't build in your
|
|
source tree)
|
|
|
|
2. Some cmake backends may want your compile tools in PATH. (Hint: "Visual
|
|
Studio Command Prompt")
|
|
|
|
3. set CMAKE_LIBRARY_PATH=d:\path\to\prereq1\lib;d:\path\to\prereq2\lib;...
|
|
|
|
4. set CMAKE_INCLUDE_PATH=d:\path\to\prereq1\include;d:\path\to\prereq2\include;...
|
|
|
|
5. cmake -G "some backend, like 'NMake Makefiles'"
|
|
-DCMAKE_INSTALL_PREFIX=d:/path/to/aprinst
|
|
-DAPR-Util-specific-flags
|
|
d:/path/to/aprutilsource
|
|
|
|
If APR 1.x was installed to a different directory than APR-Util,
|
|
also pass these additional arguments:
|
|
|
|
-DAPR_INCLUDE_DIR=d:/path/to/apr1inst/include
|
|
-DAPR_LIBRARIES=d:/path/to/apr1inst/lib/libapr-1.lib
|
|
|
|
Alternately, use cmake-gui and update settings in the GUI.
|
|
|
|
APR-Util feature flags:
|
|
|
|
APU_HAVE_CRYPTO Build crypt support (only the OpenSSL
|
|
implementation is currently supported)
|
|
Default: OFF
|
|
APU_HAVE_ODBC Build ODBC DBD driver
|
|
Default: ON
|
|
APR_BUILD_TESTAPR Build APR-Util test suite
|
|
Default: OFF
|
|
TEST_STATIC_LIBS Build the test suite to test the APR static
|
|
library instead of the APR dynamic library.
|
|
Default: OFF
|
|
In order to build the test suite against both
|
|
static and dynamic libraries, separate builds
|
|
will be required, one with TEST_STATIC_LIBS
|
|
set to ON.
|
|
INSTALL_PDB Install .pdb files if generated.
|
|
Default: ON
|
|
|
|
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.
|
|
|
|
6. build using chosen backend (e.g., "nmake install")
|
|
|
|
Known Bugs and Limitations
|
|
--------------------------
|
|
|
|
* If include/apu.h or other generated files have been created in the source
|
|
directory by another build system, they will be used unexpectedly and
|
|
cause the build to fail.
|
|
* Options should be provided for remaining features, along with finding any
|
|
necessary libraries
|
|
+ DBM:
|
|
. APU_HAVE_GDBM
|
|
. APU_HAVE_NDBM
|
|
. APU_HAVE_DB
|
|
+ DBD:
|
|
. APU_HAVE_PGSQL
|
|
. APU_HAVE_MYSQL
|
|
. APU_HAVE_SQLITE3
|
|
. APU_HAVE_SQLITE2
|
|
. APU_HAVE_ORACLE
|
|
+ CRYPTO:
|
|
. APU_HAVE_NSS
|
|
+ XLATE, APU_HAVE_ICONV (no way to consume an apr-iconv build yet)
|
|
* Static builds of APR modules are not supported.
|
|
* CHANGES/LICENSE/NOTICE is not installed, unlike Makefile.win.
|
|
(But unlike Makefile.win we want to call them APR-Util-CHANGES.txt
|
|
and so on.) But perhaps that is a job for a higher-level script.
|
|
|
|
Generally:
|
|
|
|
* Many APR-Util features have not been tested with this build.
|
|
* Developers need to examine the existing Windows build in great detail and see
|
|
what is missing from the cmake-based build, whether a feature or some build
|
|
nuance.
|
|
* Any feedback you can provide on your experiences with this build will be
|
|
helpful.
