| Experimental cmake-based build support for APR on Microsoft Windows |
| |
| Status |
| ------ |
| |
| This build support is currently intended only for Microsoft Windows. |
| |
| This build support is experimental. Specifically, |
| |
| * It does not support all features of APR. |
| * 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.) |
| * 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: |
| |
| * Either expat or libxml2 |
| |
| Additional 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-specific-flags |
| d:/path/to/aprsource |
| |
| Alternately, use cmake-gui and update settings in the GUI. |
| |
| APR feature flags: |
| |
| Exactly one of APU_USE_EXPAT and APU_USE_LIBXML2 must be specified. |
| |
| APU_USE_EXPAT Use Expat as the underlying XML implementation |
| Default: ON |
| APU_USE_LIBXML2 Use libxml2 as the underlying XML |
| implementation |
| Default: OFF |
| APR_INSTALL_PRIVATE_H Install extra .h files which are required when |
| building httpd and Subversion but which aren't |
| intended for use by applications. |
| Default: OFF |
| 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_HAVE_IPV6 Enable IPv6 support |
| Default: ON |
| APR_BUILD_TESTAPR Build APR 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. |
| MIN_WINDOWS_VER Minimum Windows version supported by this build |
| (This controls the setting of _WIN32_WINNT.) |
| "Vista" or "Windows7" or a numeric value like |
| "0x0601" |
| Default: "Vista" |
| For desktop/server equivalence or other values, |
| refer to |
| http://msdn.microsoft.com/en-us/library/windows/ |
| desktop/aa383745(v=vs.85).aspx |
| INSTALL_PDB Install .pdb files if generated. |
| Default: ON |
| |
| LIBXML2_ICONV_INCLUDE_DIR, LIBXML2_ICONV_LIBRARIES |
| |
| If using libxml2 for the XML implementation and the build of libxml2 |
| requires iconv, set these variables to allow iconv includes |
| and libraries to be found. |
| |
| 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") |
| |
| Tested generators |
| ----------------- |
| |
| 1. NMake Makefiles |
| |
| This has been tested successfully with the following: |
| |
| * Visual Studio 2008 64-bit (requires KB948127 hot fix) |
| * Visual Studio 2012 64-bit |
| |
| 2. Visual Studio 11 (Visual Studio 2012 project files) |
| |
| Known Bugs and Limitations |
| -------------------------- |
| |
| * If include/apr.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 |
| + APR_POOL_DEBUG |
| + 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 |
| + APU_HAVE_ICONV |
| * Static builds of APR modules are not supported. |
| * XML implementation (i.e., Expat or libxml2) could support static XML impl |
| with apr-2.lib. |
| |
| Generally: |
| |
| * Many APR 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. |
