Thanks for the report. > /«PKGBUILDDIR»/engine/snappea/kernel/tables.c:229:67: error: narrowing > conversion of '-1' from 'int' to 'char' inside { } [-Wnarrowing]
I believe this is fixed by declaring the elements of index_by_permutation[] as signed char, not just char. Caveat: I haven’t tried it yet (I’m away from my usual machines). The declarations occur in two places: - engine/snappea/kernel/tables.c, line 213 - engine/snappea/kernel/tables.h, line 30 The array is never actually used in regina, so there should be no side-effects. - Ben.
