NAME Alien::MSYS - Tools required for automake scripts in Windows VERSION version 0.04 SYNOPSIS from Perl: use Alien::MSYS; # runs uname from MSYS my $uname = mysy { `uname` }; From Prompt/Makefile C:\> perl -MAlien::MSYS -e msys_run uname DESCRIPTION MSYS provides minimal shell and POSIX tools on Windows to enable autoconf scripts to run. This module aims to provide an interface for using MSYS on Windows and act as a no-op on Unix like operating systems which already have that capability. If you use this module, I recommend that you list this as a prerequisite only during MSWin32 installs. When installing, this distribution looks in the default location for an existing MSYS install, which is C:\MinGW\msys\1.0\bin, if it cannot find it there, then it will download and install MSYS in this distribution's share directory (via File::ShareDir). You can override this logic and specify your own location for MSYS using the PERL_ALIEN_MSYS_BIN environment variable. This should point to the directory containing the MSYS executables: C:\> set PERL_ALIEN_MSYS_BIN=D:\MinGW\msys\bin Keep in mind that this environment variable is consulted during both install and at run-time, so it is advisable to set this in the System Properties control panel. FUNCTIONS msys # get the uname from MSYS my $uname = msys { `uanem` }; # run with GNU make from MSYS instead of # dmake from Strawberry Perl msys { system 'make' }; This function takes a single argument, a code reference, and runs it with the correctly set environment so that calls to the system function or the qx quote like operator will use MSYS instead of the default environment. msys_run # pass command through @ARGV C:\> perl -MAlien::MSYS -e msys_run uname # pass command through @_ C:\> perl -MAlien::MSYS -e "msys_run 'make'; msys_run 'make install'" This function runs a command with the MSYS environment. It gets the command and arguments either as passed to it, or if none are passed the the command is expected to be in @ARGV. If the command fails then it will exit with a non-zero error code. This is useful, in the second example above if either make or make install fails, then the whole command will fail, also make install will not be attempted unless make succeeds. msys_path This function returns the full path to the MSYS bin directory.
