Building of the library and execution of the sample programs have been checked in the following environment.

OS:              CentOS 6.9(x64)
SWIG:            3.0.12
GCC:             4.4.7
Perl:            5.26
GridDB Server and C Client:   4.0 CE

QuickStart

Preparations

Install SWIG as below.

$ wget https://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz
$ tar xvfz pcre-8.39.tar.gz
$ cd pcre-8.39
$ ./configure
$ make
$ make install

$ wget https://prdownloads.sourceforge.net/swig/swig-3.0.12.tar.gz
$ tar xvfz swig-3.0.12.tar.gz
$ cd swig-3.0.12
$ ./configure
$ make
$ make install

If required, change INCLUDES_PERL path in Makefile.

Set LIBRARY_PATH.

export LIBRARY_PATH=$LIBRARY_PATH:<C client library file directory path>

Build and Run

1. Execute the command on project directory.

$ make

2. Insert "use griddb_perl" in Perl.

How to run sample

GridDB Server need to be started in advance.

1. Set LD_LIBRARY_PATH and PERL5LIB

    export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:<C client library file directory path>

    export PERL5LIB=<installed directory path>

2. The command to run sample

    $ perl sample/sample1.pl <GridDB notification address> <GridDB notification port>
        <GridDB cluster name> <GridDB user> <GridDB password>
      -->
      $VAR1 = [
          'name02',
          0,
          2,
          'ABCDEFGHIJ'
      ];
