Here is a workaround -- use a newer compiler like clang-11

It's a fairly common problem. Using legacysupport is a cheaper workaround. See #66055 for an example.

[jmroot (Joshua Root)]

It's already using legacysupport, and requiring a C11 capable compiler. What it's not doing is passing -std=c11 to the compiler.

[ryandesign (Ryan Carsten Schmidt)]

Because tree-sitter-cpp is using the tree_sitter portgroup which completely overrides the configure, build, and destroot phases with its own commands. Why does it do that? ​tree-sitter-cpp ships with a Makefile that does specify -std=c11. Why isn't the port using that?

[rmottola (Riccardo)]

I have the same issue on mavericks 10.9 with default apple compiler, I only had clang 16 from macports handy and that one worked too.

[rmottola (Riccardo)]

On 10.9, also gcc 13 does the trick. Just tried.

It does now: ​https://github.com/macports/macports-ports/blob/4de12fc05e86f50a6fedf678b91bfc951cb04fb5/devel/tree-sitter-cpp/Portfile#L29

[rmottola (Riccardo)]

I still have this issue 10.9. Upgrade fails. clang 7.0 works too.
