Install the dependencies (For running make)

sudo apt-get install libreadline-dev
sudo apt-get install tcl-dev
sudo apt-get install libffi-dev

Note

• Once tcl-dev package is installed, one might then possibly come across the code expecting tcl.h to be in /usr/include/, but in order to facilitate multiple versions of tcl being installed, Linux places tcl.h in /usr/include/tcl/ i.e., one extra directory level.
• Replacing ‘#include ' with '#include <tcl/tcl.h>' in the source code for the build should get around this.
• For installing klayout follow their official document.

For changing path of tcl library in source file

$sed -i 's+<tcl.h>+<tcl/tcl.h>+g' filepath
