The file lists the gmp package. 1. To use the gmp package in mswin, `win32/configure.bat` shows an option of `--with-gmp`. This option is not used in the `windows.yml` workflow file, nor is it mentioned in `doc/windows.md`. 2. When using the option, the build fails when compiling `bignum.c`, as it can���t find `gmp.h`. It appears the vcpkg include folder is not being passed to `cl`? So, it seems a few things are amiss. `gmp` was added a long time ago. With current mswin builds, will `gmp` improve `Bignum`���s performance? Is that unknown? If there are benchmarks to determine this, I could certainly run them��� -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
