26The following Libevent specific CMake variables are as follows (the values being
27the default).
28
29```
30# Type of the library to build (SHARED or STATIC)
31# Default is: SHARED for MSVC, otherwise BOTH
32EVENT__LIBRARY_TYPE:STRING=DEFAULT

35EVENT_INSTALL_CMAKE_DIR:PATH=lib/cmake/libevent
36
37# Enable running gcov to get a test coverage report (only works with
38# GCC/CLang). Make sure to enable -DCMAKE_BUILD_TYPE=Debug as well.
39EVENT__COVERAGE:BOOL=OFF
40
41# Defines if Libevent should build without the benchmark executables
42EVENT__DISABLE_BENCHMARK:BOOL=OFF

67
68# When cross compiling, forces running a test program that verifies that Kqueue
69# works with pipes. Note that this requires you to manually run the test program
70# on the the cross compilation target to verify that it works. See CMake
71# documentation for try_run for more details
72EVENT__FORCE_KQUEUE_CHECK:BOOL=OFF
73```
74
75__More variables can be found by running `cmake -LAH <sourcedir_path>`__
76
77
78## CMake (Windows)
79
80Install CMake: <https://www.cmake.org>
81
82
83     $ md build && cd build
84     $ cmake -G "Visual Studio 10" ..   # Or whatever generator you want to use cmake --help for a list.
85     $ start libevent.sln
86
87## CMake (Unix)
88
89     $ mkdir build && cd build
90     $ cmake ..     # Default to Unix Makefiles.
91     $ make
92     $ make verify  # (optional)
93
94
95# 1. BUILDING AND INSTALLATION (In Depth)
96
97## Autoconf
98
99To build Libevent, type
100
101     $ ./configure && make
102
103
104 (If you got Libevent from the git repository, you will
105  first need to run the included "autogen.sh" script in order to
106  generate the configure script.)
107
108You can run the regression tests by running
109
110     $ make verify
111
112Install as root via
113
114     $ make install
115
116Before reporting any problems, please run the regression tests.
117
118To enable low-level tracing, build the library as:
119
120     $ CFLAGS=-DUSE_DEBUG ./configure [...]
121
122Standard configure flags should work.  In particular, see:
123
124     --disable-shared          Only build static libraries.
125     --prefix                  Install all files relative to this directory.
126
127
128The configure script also supports the following flags:
129
130     --enable-gcc-warnings     Enable extra compiler checking with GCC.
131     --disable-malloc-replacement
132                               Don't let applications replace our memory
133                               management functions.
134     --disable-openssl         Disable support for OpenSSL encryption.
135     --disable-thread-support  Don't support multithreaded environments.
136
137## CMake (Windows)
138
139(Note that autoconf is currently the most mature and supported build
140environment for Libevent; the CMake instructions here are new and
141experimental, though they _should_ be solid.  We hope that CMake will
142still be supported in future versions of Libevent, and will try to
143make sure that happens.)
144
145First of all install <https://www.cmake.org>.
146
147To build Libevent using Microsoft Visual studio open the "Visual Studio Command prompt" and type:
148
149```
150$ cd <libevent source dir>
151$ mkdir build && cd build
152$ cmake -G "Visual Studio 10" ..   # Or whatever generator you want to use cmake --help for a list.
153$ start libevent.sln
154```
155
156In the above, the ".." refers to the dir containing the Libevent source code.
157You can build multiple versions (with different compile time settings) from the same source tree
158by creating other build directories.
159
160It is highly recommended to build "out of source" when using
161CMake instead of "in source" like the normal behaviour of autoconf for this reason.
162
163The "NMake Makefiles" CMake generator can be used to build entirely via the command line.
164
165To get a list of settings available for the project you can type:
166
167```
168$ cmake -LH ..
169```
170
171### GUI
172
173CMake also provides a GUI that lets you specify the source directory and output (binary) directory
174that the build should be placed in.

176# 2. USEFUL LINKS:
177
178For the latest released version of Libevent, see the official website at
179<http://libevent.org/> .
180
181There's a pretty good work-in-progress manual up at
182   <http://www.wangafu.net/~nickm/libevent-book/> .
183
184For the latest development versions of Libevent, access our Git repository
185via
186
187```
188$ git clone https://github.com/libevent/libevent.git
189```
190
191You can browse the git repository online at:
192
193<https://github.com/libevent/libevent>
194
195To report bugs, issues, or ask for new features:
196
197__Patches__: https://github.com/libevent/libevent/pulls
198> OK, those are not really _patches_. You fork, modify, and hit the "Create Pull Request" button.
199> You can still submit normal git patches via the mailing list.
200
201__Bugs, Features [RFC], and Issues__: https://github.com/libevent/libevent/issues
202> Or you can do it via the mailing list.
