or-tools fails to build. #18

Closed stevenshack closed 3 years ago

stevenshack commented 3 years ago

Rice 4.0.2 seems to change where headers are placed which causes or-tools builds to fail..

The error log below is from macOS 10.15.7 with ruby 3.0.1 installed via rbenv.

Looking at the rice package is a single header file now?

Hey @stevenshack, thanks for reporting. Will push a new release in the next few days, but for now, you can use gem "rice", "~> 3".

ankane commented 3 years ago

Just pushed 0.5.1 that uses Rice 4

stevenshack commented 3 years ago

Sorry for the slow reply. Thanks for this! I'm currently dealing with how to run or-tools under ruby 2.5.x ... Only transitionally though. Any ideas there? any rice < 4 refuses to build.

stevenshack commented 3 years ago

I figured this out. If multiple versions of rice are installed the build scripts will happily use the wrong version. Automake picking the wrong libs/include directory? I'm not sure how to make gem/bundler use the correct gem regardless.

Also, rice has an undeclared dependency on automake.

ankane commented 3 years ago

If you're using Bundler, it should use the Rice version in your Gemfile, and yeah, Rice < 4 depends on automake.
