Version 2 of Godzilla Guides to tclquadcode

Updated 2018-02-01 11:39:30 by dbohdan

This is a set of how-to notes for using the new tclquadcode. Your mileage may (WILL!) vary depending on which platform you are setting up, but this shows some of the pitfalls and workarounds you may run into.

Setup for Ubuntu 16.04

These are the steps to install and test the new quadcode on a fresh installation of Ubuntu 16.04

  • Install the X11 dev libraries to compile Tk.
  • The X includes may not be installed by default on your system.
 sudo apt-get install libx11-dev
  • Update the system.
 sudo apt-get update
 sudo apt-get upgrade
  • Install the LLVM requirements: definitely clang, maybe lldb.
 apt-add-repository "deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-5.0 m$
 apt-get update
 apt-get install -y clang-5.0
 apt-get install -y lldb-5.0
  • Download the master branch archive for llvmtcl.
 wget https://github.com/dkfellows/llvmtcl/archive/master.tar.gz -O ~/Downloads/llvmtcl-master.tar.gz
  • Create and cd to your base development directory for tclquadcode — you'll end up with tcl, tk, quadcode, and llvmtcl-master in this directory.
 cd ~/your-dir
 tar xvf ~/Downloads/llvmtcl-master.tar.gz
 cd ~/Downloads  # For example.
 tar xvf tcllib-1.18.tar.gz
 cd tcllib-1.18
 ./configure
 make
 sudo make install
 cd ~/your-dir
 fossil clone http://core.tcl.tk/tcl tcl.fos
 fossil clone http://core.tcl.tk/tk tk.fos
 fossil clone http://core.tcl.tk/tclquadcode quadcode.fos
  • Build and install tcl, tk, and llvmtcl.
 mkdir tcl tk
 cd tcl
  • Do not take the tip - It may have issues.
 fossil open ../tcl.fos core-8-6-8
 cd unix
 ./configure; make
 sudo make install

 cd ../../tk
 fossil open ../tk.fos core-8-6-8
 cd unix
 ./configure; make
 sudo make install

 cd ../../llvmtcl-master
 ./configure
  • This fails because there is no llvm_config command.
  • That's because the llvm 5.0 package calls it llvm-config-5.0.
 cd /usr/bin
 sudo ln -s llvm-config-5.0 llvm-config
 cd -
 ./configure
 make
 sudo make install
  • Note: if you get errors like below, you are using a 9.x version of Tcl that as of Jan 2018 is not supported.
 version conflict for package "Tcl": have 9.0a0, need 8.5
    while executing
 "package require Tcl 8.5"
 Or:
 version conflict for package "Tcl": have 9.0a0, need 8.2
    while executing
 "package require Tcl 8.2"
    (file "./installer.tcl" line 10)
  • Make a directory for quadcode. I'm using a date-stamped directory to keep the evolutionary steps separate.
 mkdir quad-201801
 cd quad-201801/
 fossil open ../quadcode.fos
 tclsh8.6 demos/smalltest.tcl
  • This should "just work", and you'll see about a factor of 10 improvement in run time.
