NAME

libdataset

SYNOPSIS

Use via C.

include "libdataset.h"

Use via Python.

from py_dataset import dataset

DESCRIPTION

libdataset is a C shared library based on the Go package called dataset from Caltech Library. The dataset package provides a unified way of working with JSON documents as collections. libdataset was create better integrate working with dataset collection from Python via the py_dataset Python package.

Requirements

To compile libdataset you need both a the Go 1.20 toolchain and a POSIX C toolchain including GNU Make. You need to understand your C compiler options to include the dataset shared libraries generated via the Go compiler.

Compiling libdataset

The following includes some general notes about compiling libdataset.

Linux/Darwin

To compile you need to have Go 1.20 and GNU Make. Running make in this directory will generate the compiled shared library and create header file (e.g. libdataset.so, libdataset.dll, or libdataset.dylib and libdataset.h). You can then copy the shared library and header file to an appropriate on your system.

Windows 11

Install Go 1.20 or better from the Golang website using the provided Windows binaries. Install Miniconda (from Anaconda). Using Miniconda install git, gcc (i.e. m2w64-gcc) and zip (m2-zip). Run “make.bat” to compile DLL. Modify and run release.bat to generate a release version.

Issues

• Windows 11: Need to install gcc and git via Miniconda after installing the Go binaries for Windows from the golang.org website
• Mac OS X (Darwin): only one Go c-shared library seems possible at in a python session, the Go code doesn’t seem to be movable in memory, this is related to a long standing issue in Mac OS X only supporting xcode’s linker
