NAME

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

SYNOPSIS

With the Extutils::MakeMaker manpage:

    use ExtUtils::CppGuess;
    
    my $guess = ExtUtils::CppGuess->new;
    
    WriteMakefile
      ( # MakeMaker args,
        $guess->makemaker_options,
        );

With the Module::Build manpage:

    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 the Module::Build manpage constructor or to the ExtUtils::MakeMaker manpage'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.
