Thank you for a problem report. Current source in 5.0.27-BK is still the same.

Sorry to say: The proposed patch is wrong. It may fix the immediate "configure" problem, but that is just due to an inconsistency withing "libedit": The header files do not match the function specification and use. As a consequence, my changeset for this (see previous "patch pending") was wrong as well and will not be pushed. I am working on a more thorough fix.

Change it to "CPFunction *" and get rid of the casts.

The patch is pushed into the trees for versions 5.0.36 and 5.1.16-beta. It contains a cleanup for the "libedit" header file making it consistent with that for "readline" and avoiding several casts. I am *not* sure whether this is sufficient to solve the NetBSD issue, though, but I have no suitable environment. So I would appreciate it very much if the reporter, JuanRP, or somebody else with a suitable setup could download the patch, try it, and report back. I hope that with my fix we have a consistent base to fix any issue specific to NetBSD.

Noted in 5.0.36, 5.1.16 changelogs. readline detection did not work correctly on NetBSD.
Description: Readline detection in latest version of mysql-5.x is broken, it tries to run a function callback via a pointer, which is wrong on NetBSD. The following patch fixes the problem and we've been using it on the NetBSD packages collection (pkgsrc) for long time now. It would be nice if you can apply it for the next version, thanks. How to repeat: cd pkgsrc/databases/mysql5-client && make configure Suggested fix: Please apply the following patch (we are using this patch on the NetBSD packages collection): --- config/ac-macros/readline.m4.orig 2006-10-14 19:03:29.000000000 +0200 +++ config/ac-macros/readline.m4 2006-10-14 19:03:37.000000000 +0200 @@ -26,7 +26,7 @@ #include "readline/readline.h" ], [ - char res= *(*rl_completion_entry_function)(0,0); + char res= (*rl_completion_entry_function)(0,0); completion_matches(0,0); ], [
