ExtUtils::CppGuess(3)

NAME
ExtUtils::CppGuess - guess C++ compiler and flags

SYNOPSIS
With Extutils::MakeMaker:

    use ExtUtils::CppGuess;

    my $guess = ExtUtils::CppGuess->new;

    WriteMakefile
      ( # MakeMaker args,
        $guess->makemaker_options,
        );

With Module::Build:

    my $guess = ExtUtils::CppGuess->new;

    my $build = Module::Build->new
      ( # Module::Build arguments
        $guess->module_build_options,
        );
    $build->create_build_script;

DESCRIPTION
"ExtUtils::CppGuess" attempts to guess the system's C++ compiler that is compatible with the C compiler that your perl was built with.

It can generate the necessary options to the Module::Build constructor or to ExtUtils::MakeMaker's "WriteMakefile" function.

METHODS

  new
Creates a new "ExtUtils::CppGuess" object. Takes the path to the C compiler as the "cc" argument, but falls back to the value of $Config{cc}, which should be what you want anyway.

You can specify "extra_compiler_flags" and "extra_linker_flags" (as strings) which will be merged in with the auto-detected ones.

  module_build_options
Returns the correct options to the constructor of "Module::Build". These are:

    extra_compiler_flags
    extra_linker_flags

  makemaker_options
Returns the correct options to the "WriteMakefile" function of "ExtUtils::MakeMaker". These are:

    CCFLAGS
    dynamic_lib => { OTHERLDFLAGS => ... }

If you specify the extra compiler or linker flags in the constructor, they'll be merged into "CCFLAGS" or "OTHERLDFLAGS" respectively.

  is_gcc
Returns true if the detected compiler is in the gcc family.

  is_msvc
Returns true if the detected compiler is in the MS VC family.

  add_extra_compiler_flags
Takes a string as argument that is added to the string of extra compiler flags.

  add_extra_linker_flags
Takes a string as argument that is added to the string of extra linker flags.
