Fixing X11 Error on macOS Catalina for AmberTools 18/19
I was trying to install AmberTools on my macOS Catalina Installation. Running
./configure -macAccelerate clang gave me an error that it could not find X11 libraries, even though
locate libXt showed that my installation was correct.
Could not find the X11 libraries; you may need to edit config.h to set the XHOME and XLIBS variables. Error: The X11 libraries are not in the usual location ! To search for them try the command: locate libXt On new Fedora OS's install the libXt-devel libXext-devel libX11-devel libICE-devel libSM-devel packages. On old Fedora OS's install the xorg-x11-devel package. On RedHat OS's install the XFree86-devel package. On Ubuntu OS's install the xorg-dev and xserver-xorg packages. ...more info for various linuxes at ambermd.org/ubuntu.html To build Amber without XLEaP, re-run configure with '-noX11: ./configure -noX11 --with-python /usr/local/bin/python3 -macAccelerate clang Configure failed due to the errors above!
I searched on Google for a solution. Sadly, there was not even a single thread which had a solution about this error.
Simply reinstalling XQuartz using homebrew fixed the error
brew cask reinstall xquartz
If you do not have XQuartz installed, you need to run
brew cask install xquartz
