Redcurrant is a software solution for objects storage, targetting very large-scale unstructured data volumes.

As described here, the code is licensed under the terms of two licenses: LGPL3 for client-relaed files, AGPL3 for all the others. Please find in the LICENSE file more details about this.

There are a few different ways you can install Redcurrant:

• Download the zipfile from the downloads page and install it.
• Checkout the source: git clone git://github.com/redcurrant/redcurrant.git and install it yourself.

Go to http://www.redcurrant.io for documentations about installation and configuration of Redcurrant.

The build process of Redcurrant's core depends on:

• cmake, make, cp, seq, bison, flex
• asn1c
• glib2
• openssl
• libevent
• perl, perl-Template-Toolkit: in its early years, these were used as code generators. This is a legacy code.
• python: more recently, the code generators became base-python scripts.

In additon, the build process of Redcurrant's crawler tools repends on:

• json-c
• zeromq3
• debus

The Makefile's generation is performed by cmake. The master CMake directives files accepts several options. Each option has to be specified on the cmake's command line with the following format:

cmake -D${K}=${V} ${SRCDIR}

In addition to common cmake options, these specific options are also available:

• PREFIX : an alternative to the cmake's CMAKE_INSTALL_PREFIX
• MOCKS : define it to allow mock'ing syscalls and socket operations.
• SOCKET_OPTIMIZED : define if to use socket3 and accept4 syscalls
• EXE_PREFIX : define it to a prefix to be prepended to every executable generated. If not specified, a legacy format will be used.
• SOCKET_LINGER_ONOFF : (integer value) triggers the onoff value of the SO_LINGER configuration.
• SOCKET_LINGER_DELAY : (integer value) set it to the delay in milliseconds, this will the delay part of the SO_LINGER configuration.
• ALLOW_DEPRECATED : define it to hide warnings for deprecated symbols from the GLib2

In addition, some options axist to specify uncommon installation paths. Their format is ${DEP}_INCDIR or ${DEP}_LIBDIR, and DEP might take the given values:

• MYSQL : idem for MySQL
• ZK : Apache ZooKeeper
• ZMQ : ZeroMQ (>=3.1)
• ASN1C : asn1c, our modified version of the original asn1c
• GRIDINIT : gridinit
• LIBRAIN : ?

Now that cmake succeeded, it is time to build and install the binaries with make.

make
make test
make DESTDIR=${install_dir} install
