Ruby-build: configure: error: something wrong with LDFLAGS="-L...

I can't seem to get ruby-build to work on OSX. Any ideas?

I had a similar issue. Turned out that I had the following in my .bash_profile. Commenting it out fixed my issues. I have a feeling this led to some conflicts with system libraries

#export LIBRARY_PATH=/opt/local/lib:/usr/local/lib

[ssbarnea]

Can we please have this fixed? It cripples user experience.

I know that setting CFLAGS='' is a way to bypass this bug but this is not an excuse for having a broken default behaviour. Clearly the CFLAGS value is valid but somehow ruby-builds seems to consider itself as being too smart.

[timwr]

For me the issue was the $PATH variable, not the $LIBRARY_PATH.
@ssbarnea double check your .bash_profile/.bashrc/.profile and environment variables.

In case anybody else runs into this issue recently, the LDFLAGS error was occuring when I was trying to rbenv install 2.5.3. I tried setting the path, reinstalling openssl, and other suggestions but what eventually solved it was to upgrade XCode from 9.4 to the latest 10.1

[sreeni-everest]

I faced this issue on Mojave when I was using an older version of Xcode. (I had downgraded to 9.4 from 10.3). I resolved this issue by installing latest version of Command Line Tools and running:
sudo xcode-select -s /Library/Developer/CommandLineTools

Yup, I'm running more than one xcode as an older version is a dependancy for an older rails project that I have. I've got a newer version in /Applications, so using that let me install:

sudo xcode-select -s /Applications/Xcode.app/

I was running into openssl related issue:

Error running './configure --prefix=/Users/<user>/.rvm/rubies/ruby-2.7.0  --with-opt-dir=/usr/local/opt/libyaml:/usr/local/opt/libksba:/usr/local/opt/readline:/usr/local/opt/zlib:/usr/local/opt/[email protected] --disable-install-doc --enable-shared',

Ran brew install openssl
then it told to reinstall run: brew reinstall [email protected], so I re-installed
Then at the end, it said to add these vars in .zshrc

If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

For pkg-config to find [email protected] you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"

so i added these in .zshrc:

# openssl 1.1
PATH="/usr/local/opt/[email protected]/bin:$PATH"
LDFLAGS="-L/usr/local/opt/[email protected]/lib"
CPPFLAGS="-I/usr/local/opt/[email protected]/include"
PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"

to get these in my already opened terminal, I ran source ~/.zshrc

the updating ruby using rvm worked: rvm install "ruby-2.7.0"

[Mohamed-yakout]

I run the following:

echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bashrc
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile

And then run

rvm install "ruby-2.7.0"

it's working with me.
