Comment 1 Bartosz Szreder 2009-09-11 11:43:09 UTC
This is due to improvements in handling const-corectness in gcc-4.4

I looked at the code and it's not trivial to fix, because a pointer obtained by strchr function is later manipulated. If it wouldn't be then patching kcontrol would be a simple "char *" => "const char *" conversion.

Gentoo KDE Team: is it worth fixing (if so, I can come up with a patch) or KDE 3 is going to be nuked soon from portage?
Comment 2 Petr Kočmíd 2009-09-11 13:23:22 UTC
since the kde 3.5.10 stuff is alrady in kde-sunset overlay, hopefully to keep it there in working state as long as would be possible, your patch is very welcome :)
Comment 3 Bartosz Szreder 2009-09-11 16:11:39 UTC
kcontrol-3.5.10 compiles fine on my machine with gcc-4.1.1. Please sync your portage tree - there's already a patch for this issue.

I think this can be closed as RESOLVED INVALID?
Comment 4 Ryan Hill (RETIRED) gentoo-dev 2009-09-13 05:03:13 UTC
yep, already fixed.
