Rake::ExtensionCompiler

HACK: Lousy API design, sue me. At least works ;-)

Define a series of helpers to aid in search and usage of MinGW (GCC) Compiler by gem developer/creators.

Public Class Methods

mingw_gcc_executable() click to toggle source

return the first compiler found that includes both mingw and gcc conditions (this assumes you have one installed)

    # File lib/rake/extensioncompiler.rb, line 35
35:     def self.mingw_gcc_executable
36:       return @mingw_gcc_executable if @mingw_gcc_executable
37: 
38:       # grab the paths defined in the environment
39:       paths = ENV['PATH'].split(File::PATH_SEPARATOR)
40: 
41:       # the pattern to look into (captures *nix and windows executables)
42:       pattern = "*mingw*gcc{,.*}"
43: 
44:       @mingw_gcc_executable = paths.find do |path|
45:         # cleanup paths before globbing
46:         gcc = Dir.glob("#{File.expand_path(path)}/#{pattern}").first
47:         break gcc if gcc
48:       end
49: 
50:       @mingw_gcc_executable
51:     end
mingw_host() click to toggle source

return the host portion from the installed MinGW

    # File lib/rake/extensioncompiler.rb, line 13
13:     def self.mingw_host
14:       return @mingw_host if @mingw_host
15: 
16:       # the mingw_gcc_executable is helpful here
17:       if target = mingw_gcc_executable then
18:         # we only care for the filename
19:         target = File.basename(target)
20: 
21:         # now strip the extension (if present)
22:         target.sub!(File.extname(target), '')
23: 
24:         # get rid of '-gcc' portion too ;-)
25:         target.sub!('-gcc', '')
26:       end
27: 
28:       raise "No MinGW tools or unknown setup platform?" unless target
29: 
30:       @mingw_host = target
31:     end
