investigating ruby build failure

Oct 20, 2023

To build ruby with the system openssl, instead of downloading and building its own copy:

RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" \
  asdf install ruby latest

To find out why my build is failing, I added set -x to ~/.asdf/plugins/ruby/bin/install:

$ git diff diff --git bin/install bin/install index b3f5cea..2aa70f9 100755 --- bin/install +++ bin/install @@ -2,6 +2,10 @@ set -euo pipefail +# added by llimllib for debugging +set -x +# DELETEME + # shellcheck source=/dev/null source "$(dirname "$0")/../lib/"

This logged the ruby-build invocation, but didn't apply to ruby-build itself. But it did show me that it ran .asdf/plugins/ruby/ruby-build/bin/ruby-build, so let's try the same trick on that

~/.asdf/plugins/ruby/ruby-build/bin/ruby-build 3.1.2 ~/.asdf/installs/ruby/3.1.2

ruby-build sources ~/.asdf/plugins/ruby/ruby-build/share/ruby-build/3.1.2, which has two commands:

install_package "openssl-3.0.5" "" openssl --if needs_openssl_102_300 install_package "ruby-3.1.2" "" ldflags_dirs enable_shared standard verify_openssl

the first doesn't execute because I gave it a proper openssl already. The second ends up calling:

build_package ruby-3.1.2 ldflags_dirs enable_shared standard verify_openssl # which then calls build_package_ldflags_dirs ruby-3.1.2

Then the trail goes cold after set - $LDFLAGS - I have no idea what that is supposed to be doing! I added a set -x after it to see if that changes anything?

That ultimately calls this make command that is failing:

oh man is it this stupid? mkdir -p ~/.asdf/installs/ruby/3.1.2/{bin,lib,include}

idea via this comment

alright if you do that before trying asdf install it doesn't work, because asdf then believes it already has version 3.1.2, so I added it to the ruby build script - now I get a new failure at least.

now we have:

ok to find those compiling messages, I had to find, which seems to have some more makefile stuff in it. That file indicates that there is a V option, which if set to 1, will cause it to log verbosely:

# V=0 quiet, V=1 verbose. other values don't work. V = 0

To set that, I just jimmied the make command to add V=1 because I didn't figure out how to add it to the argument array properly, and who cares:

# llimllib: remove V=1 when done debugging { "$MAKE" "${!PACKAGE_MAKE_OPTS_ARRAY}" $MAKE_OPTS V=1 ${!PACKAGE_MAKE_OPTS}

ok, the miniruby command that failed now shows up!

./miniruby -I./lib -I. -I.ext/common ./tool/generic_erb.rb -o \ ./template/ -- --cross=no

sadly, when I cd into the directory and run it myself, it succeeds:

$ ./miniruby -I./lib -I. -I.ext/common ./tool/generic_erb.rb -o \ ./template/ -- --cross=no updated

urgggg just going into the dir and doing make install works. Very frustrating!

ok, now asdf wrote over my version of ruby-build. So let's clone ruby-build, and work on it in its own dir:

$ RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@3)" bin/ruby-build 3.1.2 /tmp/wut ... omitted compiling yjit.c make: /opt/homebrew/bin/gmkdir: Permission denied make: *** [coroutine/arm64/.time] Error 1 make: *** Waiting for unfinished jobs....

ok let's try adding V=1 again. Here's the patch I applied:

diff --git bin/ruby-build bin/ruby-build index 517bc15..d45c4ba 100755 --- bin/ruby-build +++ bin/ruby-build @@ -568,6 +568,13 @@ build_package_standard_build() { MAKE_OPTS="-j $(num_cpu_cores)" fi + if [ "${VERBOSE+defined}" ]; then + echo "adding V=1" + MAKE_OPTS="V=1" + else + exit 1 + fi +

f*$&, it worked this time! cmon man I need you to fail here.

And now... it just succeeds with asdf, no changes required. That sucks.
