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/
