Maven NAR packaging for log4cplus

Platform-independent (noarch) NAR packaging for log4cplus.

log4cplus is a simple to use C++11 logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration. It is modeled after the Java log4j API.

Uplink information :

• https://sourceforge.net/projects/log4cplus/
• https://sourceforge.net/p/log4cplus/wiki/Home/

Using the Maven NAR plugin, you can then simply add NAR dependencies to your build - Log4cplus headers and binaries will automatically be integrated in your build.

Release Notes

Version 2.0.0

Upstream log4cplus version 2.0.0

Binaries built on :

• CERN CentOS 7 - gcc 4.8.5, libstdc++ 6, pthread (posix)
• Windows 10 64 bits - MSVC 14 (MS Visual Studio 2015)

How to use

Simply add the dependency to your Maven NAR like so :

<dependency>
  <groupId>com.github.cern.narlibs</groupId>
  <artifactId>log4cplus</artifactId>
  <version>2.0.0</version>
  <type>nar</type>
</dependency>

Note that Log4cplus v2+ requires C++ 11 (e.g. for GCC you need the option -std=c++11).

How to rebuild the upstream library

# If aclocal is reported missing...
autoreconf -f -i
make
cp .libs/liblog4cplus.so ../narlibs-log4cplus/src/nar/resources/aol/amd64-Linux-gpp/lib/
cp .libs/liblog4cplus.so ../narlibs-log4cplus/src/nar/resources/aol/amd64-Linux-gpp/lib/liblog4cplus-nar-2.0.0.so
# Copy all headers into the NAR src/nar/resources/noarch/include
cp -r includes/log4cplus ../narlibs-log4cplus/src/nar/resources/noarch/include
