ucblogo @6.2.4: error: incompatible function pointer types passing 'void (void)' to parameter of type 'void (*)(int)' [-Wincompatible-function-pointer-types]

Hi. This doesn't build, but the current version on github (still tagged as 6.2.4) builds without issue.

Hi. This doesn't build,

We also see a build failure on our buildbot; presumably this is the same error you saw:

main.c:106:19: error: incompatible function pointer types passing 'void (void)' to parameter of type 'void (*)(int)' [-Wincompatible-function-pointer-types]

I'm not sure what you mean. ​The latest released version is 6.2.4. It was released March 27, 2023 (not July 2, 2024, ​as claimed on the web site). It has the problem you experienced.

Maybe you mean the latest code in their GitHub repository which has not yet been tagged as a stable version builds for you. In that case, we would want to identify which specific change fixes the problem and backport that patch to 6.2.4. It may be one or more of the changes mentioned ​in this bug report.

Hi. Yes, I meant the current GitHub HEAD.
