I am trying to install GINAC on Mac OS. 

ginsh did not install because it could not find readline. I have already installed readline using Homebrew, and homebrew gave me the message appended below. So I used this configure option:

./configure LDFLAGS="-L/usr/local/opt/readline/lib" CPPFLAGS="-I/usr/local/opt/readline/include" PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig" 

Unfortunately, ginsh still does not compile and I get this information from configure:

***** BEGIN MESSAGE FROM CONFIGURE*****

== ginsh will not compile, because libreadline could not be found.

*****END MESSAGE FROM CONFIGURE*****

Could you please help me with the configure options to get ginsh to compile? I’ve attached the config.log as well.

Thank you!

Sincerely,

Francesca

For compilers to find readline you may need to set:

  export LDFLAGS="-L/usr/local/opt/readline/lib"

  export CPPFLAGS="-I/usr/local/opt/readline/include"

For pkg-config to find readline you may need to set:

  export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"

readline is keg-only, which means it was not symlinked into /usr/local,

because macOS provides BSD libedit.
