Log4cxx Dependencies

As of version 0.12.0, Log4cxx requires a minimum C++ version of C++11. If C++17 is not available, then Log4cxx requires Boost Thread in order to build, which in turn requires chrono and date_time.

log4cxx requires the following software to build and/or run correctly:

Dependency Name	Version	Dependency Type	Homepage
Apache Portable Runtime(APR)	>=1.5.4	Compile/Runtime	https://apr.apache.org
APR-Util	>=1.5.4	Compile/Runtime	https://apr.apache.org
Boost	any?	Compile/runtime. Not required if your compiler supports C++17	https://boost.org
gzip	any	Test/Runtime(optional)	https://gzip.org
sed	any	Test	N/A
zip	any	Test/Runtime(optional)	N/A
log4j	1.2.14	Test	https://http://logging.apache.org/log4j/2.x/
java	>=6	Test	https://adoptopenjdk.net

APR+APR-Util

The Apache Portable Runtime(APR) provides the cross-platform backend for log4cxx. Both APR and APR-util need to be installed and available on your system.

sed+gzip+zip

These applications are needed during test of log4cxx. gzipand sed are generally installed by default on Linux. zip may not be installed by default; check your distribution's documentation for information on how to install these applications.

For Windows, you will have to install those tools through a system such as MinGW, cygwin, or MSYS2.

gzip and zip only needed during runtime if you are compressing the log files, for example by setting a rollover policy which ends in .gz or .zip.

log4j+Java

log4j and Java are needed to run some tests to ensure that log4cxx has binary compatability with log4j. Note that the correct binary for log4j will be downloaded and used automatically if CMAKE is used to build the project, otherwise one needs to get that manually. Java needs to be installed on the system already in all cases, but with CMAKE again, if it's not, the corresponding tests are skipped entirely automatically.
