I ran into the following error when trying to install MYSQL2 under gems. I was trying to install MYSQL2 to be able to import content from deeemm.com into my local jekyll dev site using the instructions posted here - https://import.jekyllrb.com/docs/joomla3/ but kept getting an ssl dependency error.I got this error
linking shared-object mysql2/mysql2.bundle
ld: warning: directory not found for option '-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.Internal.sdk/usr/local/lib'
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mysql2.bundle] Error 1
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
current directory: /Library/Ruby/Gems/2.6.0/gems/mysql2-0.5.3/ext/mysql2
whilst trying to install MYSQL2 like this...
gem install -V mysql2
Oddly enough MYSQL was already installed as I have a local server set up as a development environment, but it would appear that ssl was missing. I ended up solving it with the following fix posted in the comments on stack exchange - https://stackoverflow.com/questions/3608287/error-installing-mysql2-failed-to-build-gem-native-extension
gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
Ok, ok, I know that it's not the current version of MYSQL, but it at least allowed me to run jekyll and import the posts on to my local machine.I tried substituting versions with 0.5.7 & 0.8.0 and they did not work, but I did find that the statement still worked if I removed the version switch altogether...
sudo gem install mysql2 -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
Note: the two dashes are a shorthand way of setting verbose mode '--V'I hope this saves someone a few hours head scratching./DM
