rbenv install 2.6.5 failing: BUILD FAILED (macOS 11.6 using ruby-build 20210928)

[amitmahajan12]

Please see the attached log. It is unclear to me what is wrong. I'll appreciate any help I can get.

I have this same Build Failed error with 3.0.0 except, my build fails during the install of openssl-1.1.1l. Log attached.

I had multiple versions of ruby installed. After I uninstalled everything and reinstalled only 2.6.5, it worked for me. I think failing during install of openssl-1.1.1l may be a different issue anyway.

nothing works ..

I'm getting this same error on macOS 11.6 and 12.0.1 (m1 chip), I'm going to uninstall and reinstall everything and see where that takes me

[iamricks]

I'm getting the same issue trying to install 2.6.3 but i am able to install and use 3.0.2 and 3.0.3 just fine, maybe the issue is just with 2.6.x?

[x-warukira]

export optflags="-Wno-error=implicit-function-declaration" worked for me

[JShefferCorp]

export optflags="-Wno-error=implicit-function-declaration"

Thanks, this also worked for me.
MacOS: 12.5
Processor: Apple M1 Pro

[markst]

Legend @x-warukira! That's finally fixed being unable to install 2.6.0 on my M1

[mrmeszaros]

export optflags="-Wno-error=implicit-function-declaration" worked for me

This Worked on my machine
MacOS: Ventura (13.4.1)
Processor: Apple M1 Pro

On that note - would it be possible to persistently set that variable for the context of ruby-build or rbenv-install?

@x-warukira How did You find the solution? I am interested to see what component reads the optflags variable!

[monfresh]

There are several misconceptions going on here. First, the "-Wno-error=implicit-function-declaration" flag should never be set. It's a dangerous hack that overrides macOS defaults, as explained here: #2001 (comment)

I've been using Ruby for 13 years and not a single time have I ever had to set that flag. If you have a proper Ruby dev setup, and you're installing the appropriate version of Ruby in the appropriate context, you should never need to set that flag.

The second misconception is that if your project is using a specific version of Ruby, then your only option is to install that specific version. I see so many people try to install older versions of Ruby 2.6.x, like in this GitHub issue, when the solution is to update your project to the latest patch version (the 3rd digit), which is 2.6.10.

rbenv/ruby-build can install 2.6.x versions as old as 2.6.8 on Apple Silicon Macs in native mode without any issues and without having to set any flags.

Here's a detailed article I wrote that explains how and why to upgrade the Ruby version in your project.

If for some highly unlikely reason you absolutely need to use a version of 2.6.x older than 2.6.8, then the best option is to use Rosetta.
