NAME

SPVM::Builder::Config - Configurations of Compile and Link of Native Sources

DESCRIPTION

SPVM::Builder::Config is configuration of c/c++ compile and link.

FIELDS

Fields.

ext

my $ext = $config->ext;
$config->ext($ext);

Get and set the extension of the SPVM native source.

The default is undef.

Examples:

# Foo/Bar.c
$config->ext('c');

# Foo/Bar.cpp
$config->ext('cpp');

cc

my $cc = $config->cc;
$config->cc($cc);

Get and set a compiler name. The default is the value of cc of Config module.

Examples:

# gcc
$config->cc('gcc');

# g++ for C++
$config->cc('g++');

# nvcc for CUDA/GUP
$config->cc('nvcc');

# cc that compiled this Perl
use Config;
$config->cc($Config{cc});

cc_each

my $cc_each = $config->cc_each;
$config->cc_each($cc_each);

Get and set a callback that returns the compiler name for each source file. The call back receives SPVM::Bulder::Config object and optional arguments as a hash reference.

Optional Arguments:

source_file

Each source file.
class_name

The class name

If cc_each is defined, the compiler use the return value of cc_each as the compiler name instead of cc.

Examples:

$config->cc_each(sub {
  my ($config, $args) = @_;
  
  # Source file
  my $source_file = $args->{source_file};
  
  # Class name
  my $class_name = $args->{class_name}
  
  my $cc;
  # C source file
  if ($source_file =~ /\.c$/) {
    $cc = 'gcc';
  }
  # C++ source file
  elsif ($source_file =~ /\.cpp$/) {
    $cc = 'g++';
  }
  
  return $cc;
});

include_dirs

my $include_dirs = $config->include_dirs;
$config->include_dirs($include_dirs);

Get and set header including directories of the compiler. This is same as -I option of gcc.

The default value is "SPVM/Builder/include" of one up of directory that SPVM::Buidler::Config.pm is loaded.

At runtime, the "include" directory of the native module is added before include_dirs.

ccflags

my $ccflags = $config->ccflags;
$config->ccflags($ccflags);

Get and set compiler flags.

Default:

# $Config{cccdlflags} has -fPIC.
['-fPIC']

# Other
[]

ccflags_each

my $ccflags_each = $config->ccflags_each;
$config->ccflags_each($ccflags_each);

Get and set a callback that returns the compiler flags for each source file. The call back receives SPVM::Bulder::Config object and optional arguments as a hash reference.

Optional Arguments:

source_file

Each source file.
class_name

The class name
cc

The compiler name that is the value after the process of the process of cc or cc_each.

If ccflags_each is defined, the compiler use the return value of ccflags_each as the compiler flags instead of ccflags.

Examples:

$config->ccflags_each(sub {
  my ($config, $source_file) = @_;

  # Source file
  my $source_file = $args->{source_file};
  
  # Class name
  my $class_name = $args->{class_name}

  # The compiler name
  my $cc = $args->{cc};
  
  # ccflags
  my $config_ccflags = $config->ccflags;
  
  my $ccflags = [];
  # C source file
  if ($source_file =~ /\.c$/) {
    $ccflags = ['-DFoo', @$config_ccflags];
  }
  # C++ source file
  elsif ($source_file =~ /\.cpp$/) {
    $ccflags = ['-DBar', @$config_ccflags];
  }
  
  return $ccflags;
});

optimize

my $optimize = $config->optimize;
$config->optimize($optimize);

Get and set the option for optimization of the compiler.

The default is -O3.

Examples:

$config->optimize('-O3');
$config->optimize('-O2');
$config->optimize('-g3 -O0');

optimize_each

my $optimize_each = $config->optimize_each;
$config->optimize_each($optimize_each);

Get and set a callback that returns the value of optimize for each source file. The callback receives SPVM::Bulder::Config object and optional arguments as a hash reference.

Optional Arguments:

source_file

Each source file.
class_name

The class name
cc

The compiler name that is the value after the process of the process of cc or cc_each.

If optimize_each is defined, the compiler use the return value of optimize_each as the compiler flags instead of optimize.

Examples:

$config->optimize_each(sub {
  my ($config, $source_file) = @_;

  # Source file
  my $source_file = $args->{source_file};
  
  # Class name
  my $class_name = $args->{class_name}

  # The compiler name
  my $cc = $args->{cc};
  
  # optimize
  my $config_optimize = $config->optimize;
  
  my $optimize = [];
  # C source file
  if ($source_file =~ /\.c$/) {
    $optimize = '-O3';
  }
  # C++ source file
  elsif ($source_file =~ /\.cpp$/) {
    $optimize = '-O3';
  }
  
  return $optimize;
});

source_files

my $source_files = $config->source_files;
$config->source_files($source_files);

Get and get source files. These sourceraries are linked by the compiler.

Examples:

$config->source_files(['foo.c', 'bar.c']);

ld

my $ld = $config->ld;
$config->ld($ld);

Get and set a linker. Default is ld of Config module.

lib_dirs

my $lib_dirs = $config->lib_dirs;
$config->lib_dirs($lib_dirs);

Get and set the directories that libraries are searched for by the linker. This is same as -L option of gcc.

Default:

Windows

The directory that perlxxx.dll exists

Not Windows

empty list

libs

my $libs = $config->libs;
$config->libs($libs);

Get and set libraries. These libraries are linked by the linker.

If a dynamic link library is found from "lib_dirs", this is linked. Otherwise if a static link library is found from "lib_dirs", this is linked.

Examples:

$config->libs(['gsl', 'png']);

If you want to link only dynamic link library, you can use the following hash reference as the value of the element instead of the library name.

{type => 'dynamic', name => 'gsl'}

If you want to link only static link library, you can use the following hash reference as the value of the element instead of the library name.

{type => 'static', name => 'gsl'}

resources

my $resources = $config->resources;
$config->resources($resources);

Get and get resouce module names.

At runtime, each modules' native "include" directory is added before include_dirs, and "lib" directory is added before lib_dirs.

Examples:

$config->resources(['SPVM::Resouce::Zlib::V1_15']);

ldflags

my ldflags = $config->ldflags;
$config->ldflags(ldflags);

Examples:

$config->before_link(sub {
  my ($config, $link_info) = @_;
  
  my $object_file_infos = $link_info->object_file_infos;
  
  # Do something
  
});

quiet

my $quiet = $config->quiet;
$config->quiet($quiet);
