From: Greg.mpls@... Date: 2017-05-29T16:39:03+00:00 Subject: [ruby-core:81458] [Ruby trunk Feature#13570] Using mkmf for ruby/spec C API specs Issue #13570 has been updated by MSP-Greg (Greg L). Benoit, Sorry, never set this to 'watch'. I'll try a build with MinGW. FWIW, I just got one of the spec c files to compile with only the following -- ```ruby require 'mkmf' Dir.chdir('src/build-x86_64/spec/rubyspec/optional/capi/temp') { |d| append_ldflags('-L /e/GitHub/ruby-loco/src/build-x86_64') create_makefile("bignum_spec") puts `make` require_relative 'src/build-x86_64/spec/rubyspec/optional/capi/temp/bignum_spec.so' puts CApiBignumSpecs.instance_methods(false) } ``` Output: ``` E:\GitHub\ruby-loco>ruby make_test.rb checking for whether -L /e/GitHub/ruby-loco/src/build-x86_64 is accepted as LDFLAGS... yes creating Makefile generating bignum_spec-x64-mingw32.def compiling bignum_spec.c linking shared-object bignum_spec.so rb_big_pack_array rb_big_pack_length rb_big2dbl rb_dbl2big rb_big2ll rb_big2long rb_big2str rb_big2ulong rb_big_cmp rb_big_pack ``` For the test, I only copied `bignum_spec.c` to the temp folder, along with `rubyspec.h`. I'm sure there's a setting to pick that up in `mkmf.rb`, along with several more that I'm probably missing. Again, I'm not a c type... ---------------------------------------- Feature #13570: Using mkmf for ruby/spec C API specs https://bugs.ruby-lang.org/issues/13570#change-65161 * 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) -- https://bugs.ruby-lang.org/ Unsubscribe:
