Linking issues with gcc-10

Closed this issue · 3 comments

I'm unable to compile labgtk3 3.1.0 since I've upgraded my gcc version, with ld reporting multiple definitions of ml_table_extension_events, declared in src/ml_gdk.h on line 89. The symptom looks similar as an issue reported against OCaml itself, and replacing CAMLexport by CAMLextern in the declaration (which technically, without the extern, is a "tentative definition"), as suggested there, indeed fixes the issue.

Already fixed by #105
Does it mean we need another release?

Oops, sorry I didn't see an open issue on the subject, and I didn't check the closed ones 😁. I think that a new release would be good indeed. I initially stumbled upon that by trying to compile the official lablgtk3 package on a new opam switch, and I imagine that this will happen to others, too, especially when 4.11.0 will be out.
