Hello, 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 *****BEGIN MESSAGE FROM HOMEBREW **** 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.
