Looking Terminal commands to install GHDL and GTK WAVE in Ubuntu 18.04 LTS Operating System

Error shown below -

shivam@shivam-Inspiron-N5010:~$ sudo apt-get install ghdl gtkwave
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ghdl is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Kindly help me out.

  • I looked up gtkwave (https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=gtkwave) and it's available in 'universe', do you have it enabled? (https://help.ubuntu.com/community/Repositories/Ubuntu) – guiverc Dec 28 '19 at 01:00

As others have mentioned a quick check of Ubuntu Package Search indicates that gtkwave is in the Universe repository. ghdl does not currently appear to have a package available in the repositories for Ubuntu 18.04. You can however obtain the code on github and roll your own or choose to download a binary distribution or utilize a docker image to obtain ghdl. If you aren't comfortable with compiling your own, another alternative might be to try utilizing the script developed by mathieucaroff to Download, Build, And Install ghdl. Note that I haven't tested the script but the code is straight forward and looks fine to me. There are also a couple of unsupported and untrusted Personal Archives (PPAs) that provide packages of 'ghdl': mentioned on the Launchpad Project page.

Quick search on LaunchPad PPAs - give the following PPAs with ghdl package:

  • ppa:mati75/ghdl

    with version 0.35+dfsg-1~build3
    and ghdl, ghdl-gcc, ghdl-llvm, ghdl-mcode, update-ghdl-libraries executables

  • ppa:gekkio/ghdl

    with version 0.36-0~gekkio1~bionic1
    and ghdl, ghdl1-llvm executables

You can try one of them to install GHDL.

For the gtkwave you need to have universe pocket enabled.

So the complete solution is as follows:

sudo add-apt-repository universe
sudo add-apt-repository ppa:mati75/ghdl # or ppa:gekkio/ghdl

sudo apt-get update
sudo apt-get install gtkwave ghdl*

When you want to remove PPA with GHDL - use the following commands:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:mati75/ghdl # or ppa:gekkio/ghdl
