I've recently updated my gcc to version 11, and I can't compile my
project under thec++20 standard.
Here is part of the errors gcc reports:
/usr/include/glibmm-2.68/glibmm/variant.h:910:24: error: expected
unqualified-id before ‘)’ token
910 | Variant<VariantBase>();
| ^
/usr/include/glibmm-2.68/glibmm/variant.h:971:25: error: expected
unqualified-id before ‘)’ token
971 | Variant< Variant<T> >();
| ^
/
Does this have anything to do with some new rules introduced in c++20?
Yes, C++20 is stricter in some respects, and gcc 11 is more C++20
compliant than gcc 10. Glib::Variant has been updated in the git
repository, but not yet in any released version of glibmm. See
