Config::AutoConf - A module to implement some of AutoConf macros in pure perl.


NAME

Config::AutoConf - A module to implement some of AutoConf macros in pure perl.


VERSION

Version 0.03


ABSTRACT

With this module I pretend to simulate some of the tasks AutoConf macros do. To detect a command, to detect a library, etc.


SYNOPSIS

    use Config::AutoConf;
    Config::AutoConf->check_prog("agrep");
    Config::AutoConf->check_progs("agrep", "egrep", "grep");
    Config::AutoConf->check_prog_awk;
    Config::AutoConf->check_prog_egrep;
    Config::AutoConf->check_cc();
    Config::AutoConf->check_lib("ncurses", "tgoto");
    Config::AutoConf->check_file("/etc/passwd"); # -f && -r


FUNCTIONS

check_file

This function checks if a file exists in the system and is readable by the user. Returns a boolean. You can use '-f $file && -r $file' so you don't need to use a function call.

check_files

This function checks if a set of files exist in the system and are readable by the user. Returns a boolean.

check_prog

This function checks for a program with the supplied name. In success returns the full path for the executable;

check_progs

This function takes a list of program names. Returns the full path for the first found on the system. Returns undef if none was found.

check_prog_awk

From the autoconf documentation,

  Check for `gawk', `mawk', `nawk', and `awk', in that order, and
  set output [...] to the first one that is found.  It tries
  `gawk' first because that is reported to be the best
  implementation.

Note that it returns the full path, if found.

check_prog_egrep

From the autoconf documentation,

  Check for `grep -E' and `egrep', in that order, and [...] output
  [...] the first one that is found.

Note that it returns the full path, if found.

check_cc

This function checks if you have a running C compiler.

check_lib

This function is used to check if a specific library includes some function. Call it with the library name (without the lib portion), and the name of the function you want to test:

  Config::AutoConf->check_lib("z", "gzopen");

It returns 1 if the function exist, 0 otherwise.

NEXT STEPS

Although a lot of work needs to be done, this is the next steps I intent to take.

  - detect flex/lex
  - detect yacc/bison/byacc
  - detect ranlib (not sure about its importance)

These are the ones I think not too much important, and will be addressed later, or by request.

  - detect an 'install' command
  - detect a 'ln -s' command -- there should be a module doing
    this kind of task.


BUGS

A lot. Portability is a pain. <Patches welcome!>.

Please report any bugs or feature requests to bug-extutils-autoconf@rt.cpan.org, or through the web interface at http://rt.cpan.org. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
