Actually, its has nothing to do with the Meson version I think, it's just that `fnmatch` isn't found on the OP system, and the code uses either [`cfg_data.set(varname, 1)`](https://mesonbuild.com/Reference-manual_returned_cfg_data.html#cfg_dataset) or [`cfg_data.set(name, false)`](https://mesonbuild.com/Reference-manual_returned_cfg_data.html#cfg_dataset) depending on whether it's found or not, so it doesn't have the same type in both cases when fetching it with [`cfg_data.get()`](https://mesonbuild.com/Reference-manual_returned_cfg_data.html#cfg_dataget).

Maybe something like this would be a solution (disclaimer: thoroughly untested): ```diff diff --git a/meson.build b/meson.build index 5c7bc0a04..0d714d391 100644 --- a/meson.build +++ b/meson.build @@ -94,8 +94,6 @@ foreach h : check_headers define = 'HAVE_' + h.underscorify().to_upper() if cc.has_header(h) cdata.set(define, 1) - else - cdata.set(define, false) endif endforeach
