Installing Magic on macOS (Tested on Big Sur)

With Brew

Get Homebrew.

# TCL9 should be supported soon (Q2 2025)
brew install cairo tcl-tk@8 python3
brew install --cask xquartz
./scripts/configure_mac
# If you have both TCL8 and TCL9 installed you may need to verify TCL8 was selected.
make database/database.h
make -j$(sysctl -n hw.ncpu)
make install # may need sudo depending on your setup

Without Brew

Get XQuartz

Build Tcl for X11

We are following the instructions from xschem (https://github.com/StefanSchippers/xschem/blob/master/README_MacOS.md).

We are using not opt but opt2 so that this Tcl does not interfere with tcl-tk from HomeBrew.

Extract the Tcl sources and then go to the unix folder and execute the following commands::

./configure --prefix=/usr/local/opt2/tcl-tk  
make
make install

Build Tk for X11

Extract Tk source and then go to the unix folder:

NOTE: before running 'make' inspect the Makefile and ensure the LIB_RUNTIME_DIR is set as follows. Make the correction if not:

LIB_RUNTIME_DIR         = $(libdir)

./configure --prefix=/usr/local/opt2/tcl-tk \
--with-tcl=/usr/local/opt2/tcl-tk/lib --with-x \
--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib  
make
make install

Build magic

We need to provide this tcl-tk and suppress compilation errors.

./configure --with-tcl=/usr/local/opt2/tcl-tk/lib \
--with-tk=/usr/local/opt2/tcl-tk/lib \
--x-includes=/opt/X11/include \
--x-libraries=/opt/X11/lib \
CFLAGS=-Wno-error=implicit-function-declaration
make
make install

If facing issue with layout window not opening / XQuartz:

Make sure that the output of the following command is :0.

echo $DISPLAY

if the above command doesn't display :0 then add the following line in .zshrc.

export PATH="/opt/X11/bin:$PATH"

Close & reopen terminal to load the path. Then set display manually to 0 by using the following command.

export DISPLAY=:0

Now echo DISPLAY should give :0 as output.
