Error compiling on Ubuntu 20.04 because of old catch2.hpp about viewtouch

[NeroBurner]

hmm, this shouldn't happen. Please provide more info about your used distro and compiler versions to have a starting point to debug and reproduce this issue

I resolved the issue after doing some research on the error. I am using ubuntu 20.04 and mint 21. The version of catch.hpp under the ../src/viewtouch/external/catch2 is outdated for glibc 2.35.

The steps i used to resolve the error:

• sudo apt install catch2

• in ../src/viewtouch/src/external/catch2 i made a backup copy of catch.hpp as catch.hpp.backup by issuing the command mv catch.hpp catch.hpp.backup

• i copied the file catch.hpp from /usr/include/catch2 to ../src/viewtouch/external/catch2

It built without an error

Thanks for the investigation and reporting back. So I'll need to update the embedded catch2.hpp file to a more recent version
