I'm not a c type. With MinGW builds, I've got 89 mkmf.log files in the build dir, and [test-all results](https://msp-greg.github.io/file.mingw_test-all.html) are consistent and reasonable low. I'm guessing that means yes. FYI, I ran test-spec with -j on 58760, and it matched (or very closely matched) results without -j. test-all has the same results, but assertions and skips are different. ---------------------------------------- Feature #13570: Using mkmf for ruby/spec C API specs https://bugs.ruby-lang.org/issues/13570#change-64855 * Author: Eregon (Benoit Daloze) * Status: Open * Priority: Normal * Assignee: * 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. -- https://bugs.ruby-lang.org/ Unsubscribe:
