installing older Ruby versions on OSX after XCode 12 #1489

eddroid · 2020-11-11T03:28:59Z

tldr: This is an installation problem and solution. Maybe ya'll can do something about this in ruby-build itself? Maybe not. In any case, it's here for the search bots.

Problem

$ rbenv install 2.1.7

output

Explanation

XCode 12 was released September 16, 2020. Apple changed the default CFLAGS for clang.

Clang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on).

This change prevents this version of Ruby (and possibly others) from compiling native extensions like openssl and zlib. Unfortunately, those errors only appear in the corresponding mkmf.log for the extensions.

This could also affect building some gems that use C code.

gem install <GEMNAME> -- --with-cflags="-Wno-error=implicit-function-declaration"

The text was updated successfully, but these errors were encountered:

Re: This could also affect building some gems that use C code.

I can say this already affects the mysql2 gem....

Thank you @eddroid for taking the time to write this up, I tried a lot of options and this was the only one that solved for me.

xvrdmng · 2021-04-07T04:31:52Z

Thanks for the solution!

hsbt · 2021-04-15T04:10:51Z

I pinned this to top of issue pages.

Not sure why discussion of installing 2.6.7 is closed. I am having issues installing it via ruby-install 2.6.7 and even after setting the CFLAGS variable chruby doesn't recognize it.

mislav · 2021-05-20T11:52:28Z

@normanrs ruby-install is a different project than ours: https://github.com/postmodern/ruby-install

krsinghshubham · 2021-06-02T15:37:25Z

To install rvm try these commands in order:

\curl -sSL https://get.rvm.io | bash
source /Users/sansekar/.rvm/scripts/rvm
rvm pkg install openssl
rvm install ruby-2.3.2 --with-openssl-dir=$HOME/.rvm/usr

@YudaiImazu I can't tell if your error is related to this issue. Your log only shows warnings and notes. Upload the full log into a public gist (or something like that). It's unclear if you set the CFLAGS as described in this issue.

CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.3.2

YudaiImazu · 2021-06-03T06:01:42Z

@eddroid @krsinghshubham
Thank you for helping me.
I couldn't solve this problem by setting the CFLAGS.

Above is my log.

Your reply would be appreciated.
Thank you in advance.

Please move your log output to a gist. While logged-in to GitHub, visit https://gist.github.com/ and paste your log output into there. Save it as a public gist. Then update your comment to link to your log instead of pasting the contents into a comment.

Your error isn't related to this issue. Searching for "error:", it seems to be related to X11, which is probably a problem with your version of XCode. You should create a new issue for that.

Today I had a similar issue on my MacBook Pro.

MacOS Big Sur Version 11.4
MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports)

After trial and error, the following worked.

# Ruby version that I want to install
RUBY_VERSION=2.2.10

# Install that Ruby version using rbenv
CFLAGS="-Wno-error=implicit-function-declaration" \
LDFLAGS="-L$HOME/.rbenv/versions/$RUBY_VERSION/lib -L/usr/local/opt/readline/lib -L$(brew --prefix openssl@1.0)/lib" \
CPPFLAGS="-I$HOME/.rbenv/versions/$RUBY_VERSION/include -I/usr/local/opt/readline/include -I$(brew --prefix openssl@1.0)/include" \
RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.0)" \
rbenv install $RUBY_VERSION

I hope this will help somebody.

Could an admin please delete the comment at #1489 (comment) -- it makes this issue very hard to read to the bottom, and this issue is kind of important to be easily readable, it seems to be affecting a lot of people trying to use ruby-build on latest XCode/MacOS? (I don't really understand why the issue is closed)

@YudaiImazu it is rude to paste in that many lines to a github issue comment.

xuanchien · 2021-07-24T15:46:21Z

None of the above solutions worked for me. I met this issue on Mac Big Sur when trying to install Ruby 2.6.5. The error log shows error messages like this

In file included from mjit_compile.c:133:
./mjit_compile.inc:295:70: error: expected ')'
        fprintf(f, "    const rb_serial_t ic_serial = (rb_serial_t)%"PRI_SERIALT_PREFIX"u;\n", ic_copy->ic_serial);

I suspected the Clang compiler was the issue but I could not found any solution on the internet. In the end, I could fix this issue by doing the following steps:

brew install gcc

Brew would not automatically link this gcc because it's conflicting with the default c++ path. You would see something like this

The formula built, but is not symlinked into /usr/local
Could not symlink include/c++
Target /usr/local/include/c++
already exists. You may want to remove it:
  rm '/usr/local/include/c++'

To force the link and overwrite all conflicting files:
  brew link --overwrite gcc

To list all files that would be deleted:
  brew link --overwrite --dry-run gcc

Possible conflicting files are:
/usr/local/include/c++ -> /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c+

I decided to force the link and overwrite all conflicting files (hopefully it won't affect other parts in your system, BE careful when doing this):

brew link --overwrite gcc

I also created a symlink to the new gcc

ln -s /usr/local/Cellar/gcc/11.1.0_1/lib/gcc/11 /usr/local/lib/gcc/11

Then I run the command

CC=/usr/local/Cellar/gcc/11.1.0_1/bin/gcc rbenv install 2.6.5

And finally I got Ruby 2.6.5 installed as expected. Hopefully it could help people with similar issue like me.

Ruby version that I want to install

RUBY_VERSION=2.2.10

Install that Ruby version using rbenv

this may help someone as I had the same issue and the solution was using a version of bison at 2.7.

My colleague helped me solving this problem with script below:

#!/usr/bin/env bash

set -e

# ruby-install --latest

OPENSSL_VERSION=1.1
OPENSSL_DIR=/usr/local/opt/openssl@${OPENSSL_VERSION}

function install-ruby-on-mac() {
    PKG_CONFIG_PATH=${OPENSSL_DIR}/lib/pkgconfig \
    ruby-install $(ruby-install-options $1) \
        ruby $1 \
        -- \
        --with-openssl-dir=${OPENSSL_DIR} \
        --with-opt-dir=$(brew --prefix readline) \
        --without-tcl --without-tk
}
install-ruby-on-mac 2.5.8
install-ruby-on-mac 2.6.8
install-ruby-on-mac 2.7.4

Hope it could help someone.

This helped solved my issue installing ruby 2.7.3 after upgrading from Catalina to Big Sur. Thanks!
