Alien::Libgit2

Find or build libgit2, the linkable Git library.

Synopsis

use Alien::Libgit2;

# For XS consumers
my $cflags = Alien::Libgit2->cflags;
my $libs   = Alien::Libgit2->libs;

# For FFI consumers (FFI::Platypus, Git::Libgit2)
my @libs = Alien::Libgit2->dynamic_libs;

Description

Alien::Libgit2 provides the C library libgit2 for use by other CPAN modules that need to link against it.

It first checks whether a system libgit2 (>= 1.5) is available via pkg-config. If not, it builds libgit2 from a bundled source tarball using CMake. No network access is required during install.

Installation

cpanm Alien::Libgit2

Requires a libgit2 shared library (>= 1.5). If pkg-config libgit2 is not found, the module builds from the bundled libgit2-1.9.3 tarball using CMake.
