Description

Drizzle Redux is a project which aims to breathe new life into the libdrizzle C connector. It is designed to allow you to syn- or asynchronously connect to and query a MySQL database server using a simple API.

Libdrizzle-redux is a fork of the official v5.1.4 Felmingham release available at https://launchpad.net/libdrizzle.

The primary reason for the fork is that development of the upstream stopped in 2013 which meant that crucial fixes and enhancements were not included in the latest stable release v5.1.4 Felmingham.

We hope that continuing the development of libdrizzle-redux can benefit current and future users of the library.

Releases

Latest stable release notes | All

The release process libdrizzle-redux is based on SemVer versioning as described here. This means that the major version is increased for breaking changes, the minor version is increased for feature releases, and the patch version is increased for bug fixes that don't cause breaking changes.

Releases are handled using GitHub releases. The notes associated with a major or minor GitHub release are designed to help developers to migrate from one version to another. The changes listed are the steps you need to take to move from the previous version to the one listed.

Installing Libdrizzle Redux

There are several options for installing the library:

• The project's apt repository at bintray offers deb packages for Ubuntu Xenial and Bionic.
• Build from source.
• Build and install the deb or rpm packages locally.

Please refer to the section Installing Libdrizzle Redux in the documentation for more info.

Building libdrizzle-redux

Supported compilers

Compiler	Version
GNU gcc	>=4.5.x
LLVM clang	>=3.3
Apple LLVM clang [1]	>=6.1

[1]	The version listed for Apple LLVM is the compiler used in the OS X builds on Travis CI. However earlier versions should be compatible as long as they support C++11 features, i.e. Apple LLVM 5.0, Xcode 5.0 and later.

Other Dependencies

Dependency	Version
autoconf	>=2.61
zlib1g-dev	>=0.13.x
libtool	>=2.x
libssl-dev [3]	>=v1.x

[3]	openssl is needed if libdrizzle-redux is compiled with support for SSL connections.

To build libdrizzle-redux run the following commands:

mkdir build && cd build
autoreconf -fi ..
../configure
make
make install

For more information about compiling libdrizzle-redux please refer to compiling.rst or build the documentation, cf. below.

Linking libdrizzle-redux:

Ensure the library is in your library and include paths. For releases prior to version v6.0.2 [2] linking your app against libdrizzle-redux requires the flag -ldrizzle-redux:

g++ app.c -oapp -ldrizzle-redux -lssl -lcrypto -pthread

From version v6.0.3 and later the API level of the library is appended to the installed library name. This is also reflected in the install path for development headers which now follows the pattern:

/<include-prefix>/libdrizzle-redux[MAJOR_VERSION]/libdrizzle-redux

Thus, linking against libdrizzle-redux v6.0.3 requires the flag -ldrizzle-redux6 and if headers are included to add -I/<prefix>/libdrizzle-redux6, e.g:

g++ app.c -oapp -I/usr/include/libdrizzle-redux6 -ldrizzle-redux6 -lssl -lcrypto -pthread

Another option is to link against libdrizzle-redux using the full name of the dynamic library, e.g.:

g++ app.c -oapp -I/usr/include/libdrizzle-redux6 -l:libdrizzle-redux6.so.13 -lssl -lcrypto -pthread

[2]	v6.0.2 added the major version to the package name and the library file but the release is deprecated since the linking did not work correctly.
