The build log is gigantic so I won't put it here unless someone requests it zipped.

I had this install work fine on 10.15 Catalina earlier today so something is specifically problematic with either Mojave or the specific Xcode/CommandLineTools SDK here. Or maybe it's my Homebrew-installed openssl (1.1.1d) and readline for which I believe I have appropriate flags:

export PATH="$(brew --prefix openssl)/bin:$PATH"
export LDFLAGS="-L$(brew --prefix openssl)/lib"
export CPPFLAGS="-I$(brew --prefix openssl)/include"
export PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig"

export CFLAGS="-I$(xcrun --show-sdk-path)/usr/include"
export CFLAGS="-I$(brew --prefix readline)/include $CFLAGS"
export LDFLAGS="-L$(brew --prefix readline)/lib $LDFLAGS"
export CFLAGS="-I$(brew --prefix openssl)/include $CFLAGS"

Hi, @olivierlacan, sorry you're having issues.

You may paste the whole log as a gist and link it here. I think the lines shown here are only some kind of non-fatal warnings. I can't tell what is the actual error.

To link to Homebrew openssl and readline you only need this:

RUBY_CONFIG_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" rbenv install

You shouldn't need to set any other environment variables.

[olivierlacan]

Interestingly the whole log file crashed chrome when I tried to Gist it so I’ll try again tomorrow. Am I wrong to assume that although I have OpenSSL 1.1.1d locally this shouldn’t have an effect on ruby-build since it bundles its own OpenSSL?

[mislav]

@olivierlacan You can create a gist from the command line using a tool like hub: hub gist create -c myfile.log (the gist URL will now be on the clipboard)

Yes, every ruby-build installation on macOS bundles its own OpenSSL since the system one is broken. However, to speed installations up and to have a central upgradeable OpenSSL, people often explicitly link against Homebrew openssl via the --with-openssl-dir flag. Also, using Homebrew openssl might help people avoid build issues with the bundled OpenSSL (but it doesn't look like it was the OpenSSL build that failed for you).

[hotovson]

RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" rbenv install

and everything is fine

@mislav No dice, the file is too big and leads to a server error even from hub:

$ git gist create -c /var/folders/0t/hft4_1h13wqd91mwcw2j94h80000gn/T/ruby-build.20200403030515.44193.log
Error creating gist: Bad Gateway (HTTP 502)
Server Error

So I zipped it up down to 6.9 MB from 153 MB: http://link.olivierlacan.com/3a075a45e7c1

I'm seeing a lot of warnings but the only clear error seems to be:

compile.c:9858:63: error: use of undeclared identifier 'RUBY_FUNCTION_NAME_STRING'
        rb_bug("%s: index (%d) mismatch (expect %s but %s).", RUBY_FUNCTION_NAME_STRING, i, name, table[i].name);

[tjstankus]

I had this issue and, using the same export flags as @olivierlacan original post, I was eventually able to get 2.6.5 built with asdf.

[olivierlacan]

I figured this out. I had a flag export that was overriding instead of appending flags (which is problematic because Homebrew seems to encourage overriding flag by only showing a simple export command) which led to rbenv detecting OpenSSL but not being able to link to it (I think...) and more importantly I had xcrun pointing to CLI Tools SDK headers for the wrong version of macOS somehow. xcrun can print the directory it has selected for headers and I remember finding that on some Python GitHub issues somewhere but I’m not on my main machine right now so you might be able to look it up.

I had same issue and fixed.

macOS 10.14 is EOL today. Unfortunately, I couldn't investigate and fix it. If you still face this issue with Catalina or Big Sur, Can you file it with new issue? Thanks.
