libpng12 is currently not used by Linux distros as it has a number of security vulnerabilities.
quartus: error while loading shared librariies: libpng12.so: cannot open shared object file: No such file or directory.
If you build and install libpng12, quartus complains about libsys_ictq.so
Hi SBoyc, libpng12 still is supported and deprecated.
Are you ok with error? if not I also reported and posted instruction on how to cure this error with last revision of libpng.
A lot of many other thing need be addressed on Linux and toools too, like PLL editing.
Thanks ... I have not seen the workaround and there is another guy who also reported the problem.
There is a libpng12 packages for Ubuntu but they fail to install.

Hi SBoyc, this was what I encountered on new install Mint 19.x vs Ubuntu 18.x, old one still was cured very a long long time ago.
Libpng must be installed from source, latest revision.
Linux on front of Winz user has a big issue: it work for a long time driving user to forget how they installed.
Winz instead with frequent crashes and update refresh his user to serve it and get user exercised on how to cure instead of do their jobs.
