NAME

Alien::LMDB - Build and install the LMDB embedded database

SYNOPSIS

my $lmdb = Alien::LMDB->new;

my $cflags = $lmdb->cflags;
## "-I/usr/local/share/perl/5.20.2/auto/share/dist/Alien-LMDB/include"

my $libs = $lmdb->libs;
## "-L/usr/local/share/perl/5.20.2/auto/share/dist/Alien-LMDB/lib -llmdb"

my $mdb_stat_binary = $lmdb->bin_dir . '/mdb_stat';
system("$mdb_stat_binary /path/to/db");

The above methods are inherited from Alien::Base.

If pkg-config --modversion lmdb works on your system, Alien::Base will attempt to use the system-installed lmdb. Otherwise it will use a bundled lmdb tarball.

DESCRIPTION

This module is primarily for use with LMDB_File.

Build fails on FreeBSD systems

Two things:

The build seems to require GNU make, so on FreeBSD systems (and maybe on other non-Linux systems) "gmake" should be used explicitly. Maybe using Alien::gmake can help here.
On freebsd 10 and later, there's no gcc by default installed (clang is the default compiler). So using gcc does not work. This can be fixed by calling

'gmake -C libraries/liblmdb/ CC=cc'

t/installed.t fails on Debian/stretch

I see the following test failure, only on a Debian/stretch system:

Output from './Build test':

+ pkg-config --modversion lmdb

#   Failed test 'AlienLoaded hash populated with -llmdb'
#   at t/installed.t line 13.
Use of uninitialized value in -e at t/installed.t line 14.

#   Failed test 'AlienLoaded hash of -llmdb points to existant file'
#   at t/installed.t line 14.
# Looks like you failed 2 tests of 3.
t/installed.t .. 
Dubious, test returned 2 (wstat 512, 0x200)
Failed 2/3 subtests

This system has liblmdb0_0.9.18-5 installed.
On all other of my smokers (CentOS7, Debian/jessie, FreeBSD 10+9) the test suite passes.
