From: Greg.mpls@... Date: 2017-06-02T13:16:57+00:00 Subject: [ruby-core:81524] [Ruby trunk Feature#13570] Using mkmf for ruby/spec C API specs Issue #13570 has been updated by MSP-Greg (Greg L). I'll try a MinGW build shortly. Re `IO.copy_stream`, I believe it has existed since [Ruby 1.9.3](http://ruby-doc.org/core-1.9.3/IO.html#method-c-copy_stream), which should be far enough back for current test code. Also, I've only paid attention to the files copied for capi, but all are small enough that I'd prefer one function call to the call in fs.rb that creates two blocks in ruby, then loops (in ruby) 300+ times for the copy. I patched both fs.rb and spec_helper.rb with `IO.copy_stream`, and both ran successfully. I'll start the build. ---------------------------------------- Feature #13570: Using mkmf for ruby/spec C API specs https://bugs.ruby-lang.org/issues/13570#change-65231 * Author: Eregon (Benoit Daloze) * Status: Assigned * Priority: Normal * Assignee: cruby-windows * Target version: ---------------------------------------- Hello all, I am thinking to use mkmf to compile the C API specs. https://github.com/ruby/ruby/blob/trunk/spec/rubyspec/optional/capi/spec_helper.rb is getting pretty complex and hard to maintain. I have a few questions: * Does mkmf works well on Windows? * What is a good way to compile a single .c file with mkmf to a given library file in another directory? I tried this but I am not sure it's correct: ~~~ ruby def compile_extension(name) objdir = object_path ext = "#{name}_spec" lib = "#{objdir}/#{ext}.#{RbConfig::CONFIG['DLEXT']}" require 'mkmf' # TODO: probably best to use a subprocess to avoid polluting the namespace Dir.chdir(objdir) do $srcs = ["#{extension_path}/#{ext}.c"] $objs = ["#{extension_path}/#{ext}.o"] # should probably be in objdir but that does not seem to work create_makefile(ext) system "make" end lib end ~~~ Alternatively, we can copy the needed files to a temporary directory, build there and copy the shared library back. It's a bit more work but not a big deal either. ---Files-------------------------------- spec_helper.rb (2.22 KB) spec_helper.rb (2.24 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
