error: 'HighQualityAntialiasing' is deprecated: Use Antialiasing instead [-Werror,-Wdeprecated-declarations]

Thank you for reporting this. I think this shouldn't trigger, which version of Qt you are compiling against?

Hi, thanks for the great repo. I am also seeing this error on Ubuntu 22.04

>> qmake --version
QMake version 3.1
Using Qt version 5.15.3 in /usr/lib/x86_64-linux-gnu

For what its worth, I am compiling my project w/ -Werror using g++ 11.3 and including cxxplot as shown in the README via FetchContent.

In minimal local testing, I changed the following below, which got around the error but not sure of broader impact:

Thank you for reporting! The change you made is valid for your version. I just pushed a new commit that should take care of the issue respecting the exact version the enum value was deprecated.

I would appreciate if you could fetch content using the relevant commit:

Thanks for the quick fix. Compilation succeeds but installation fails. Appears to be a minor cmake issue I fixed by doing this:

Note the addition of CMAKE_CURRENT_BINARY_DIR in place of CMAKE_BINARY_DIR which seems to be required when pulling cxxplot in as a FetchContent. I can open another issue to track this if preferred since its not the same as the title issue. Or I can open a PR w/ the fix. In any case, thank you for your help and let me know.

[Nasos Iliopoulos]

I bumped the version to v0.3.1. It should now be possible to Feth content using the particular GIT_TAG. If this doesn't work then please create a new issue and PR from the latest main commit and I will investigate.

Thank you!

[jml1795]

I think this issue is resolved, at least on my configuration. I will open another issue / PR for the installation issue.

Antialiasing enum issue Fixed in v0.3.1.
