MINIFI-293 Remove thirdparty dependencies no longer utilized inclusive of libxml2 and all of civetweb thirdparty This closes #89. Signed-off-by: Aldrin Piri <email@example.com>
MiNiFi is a child project effort of Apache NiFi. This repository is for a native implementation in C++.
Apache NiFi - MiNiFi C++ is a complementary data collection approach that supplements the core tenets of NiFi in dataflow management, focusing on the collection of data at the source of its creation. The C++ implementation is an additional implementation to the one in Java with the aim of an even smaller resource footprint.
Specific goals for MiNiFi are comprised of:
Perspectives of the role of MiNiFi should be from the perspective of the agent acting immediately at, or directly adjacent to, source sensors, systems, or servers.
The needed dependencies can be installed with the following commands for:
Yum based Linux Distributions
# ~/Development/code/apache/nifi-minifi-cpp on git:master $ yum install cmake \ gcc gcc-c++ \ libcurl-devel \ leveldb-devel leveldb \ libuuid libuuid-devel \ boost-devel \ libssl-dev \ doxygen
Aptitude based Linux Distributions
# ~/Development/code/apache/nifi-minifi-cpp on git:master $ apt-get install cmake \ gcc g++ \ libcurl-dev \ libleveldb-dev libleveldb1v5 \ uuid-dev uuid \ libboost-all-dev libssl-dev \ doxygen
OS X Using Homebrew (with XCode Command Line Tools installed)
# ~/Development/code/apache/nifi-minifi-cpp on git:master $ brew install cmake \ curl \ leveldb \ ossp-uuid \ boost \ openssl \ doxygen
From your source checkout, create a directory to perform the build (e.g. build) and cd into that directory.

The ‘conf’ directory in the root contains a template config.yml document.
This is compatible with the format used with the Java MiNiFi application. Currently, a subset of the configuration is supported and MiNiFi C++ is currently compatible with version 1 of the MiNiFi YAML schema. Additional information on the YAML format for the config.yml and schema versioning can be found in the MiNiFi System Administrator Guide.
Additionally, users can utilize the MiNiFi Toolkit Converter (version 0.0.1 - schema version 1) to aid in creating a flow configuration from a generated template exported from a NiFi instance. The MiNiFi Toolkit Converter tool can be downloaded from http://nifi.apache.org/minifi/download.html under the
MiNiFi Toolkit Binaries section. Information on its usage is available at https://nifi.apache.org/minifi/minifi-toolkit.html.

After completing a build, the application can be run by issuing the following from :
$ ./bin/minifi.sh start
By default, this will make use of a config.yml located in the conf directory. This configuration file location can be altered by adjusting the property
nifi.flow.configuration.file in minifi.properties located in the conf directory.
MiNiFi can then be stopped by issuing:
$ ./bin/minifi.sh stop
MiNiFi can also be installed as a system service using minifi.sh with an optional “service name” (default: minifi)
$ ./bin/minifi.sh install [service name]
