Speaking for the KDE 4 Release Team.. I am wondering what your plans are for KCalc in KDE4. There has been a lot of mail going on in kde-core-devel discussing some critical issues with KCalc There have? Can you provide me with a link since I can't find any such mails... I tried a full-text search on 'kcalc' in kmail. and we haven't heard from you. There was one thread on this list which grossly overstated problems (none actually exist anymore) for the app, I didn't expect any mails from bernd myself. So you mean typing 3 + 3 Enter and getting a 0 is the expected behaviour? Albert So, either I'm missing various mails, and in effect the reason for your mail, or this is based on some misunderstandings. In my tests kcalc from svn fits the role of a general purpose desktop calculator perfectly. So your mail surprises me, I'm not sure there is a strong need for a maintainer. Its got well below the average amount of bugs (22) *confused* ___ release-team mailing list release-team@kde.org https://mail.kde.org/mailman/listinfo/release-team

Hi Albert, thanks for one of your always illuminating emails :) I think that since we have seen various people try to reproduce it and it works correctly for most of them that, sure, there is something to investigate. But since you made it really clear you don't want to spent time on it, and so far you are one of the only developers actually seeing this, I fail to see that being significant in any way for kcalcs standing in the release. -- Thomas Zander pgpsTykAsMmlZ.pgp Description: PGP signature ___ release-team mailing list release-team@kde.org https://mail.kde.org/mailman/listinfo/release-team

As I said in the previous discussion this works fine here. It only seems to be an issue for people on 64 bit machines, and I suspect not even all of those. If people would get together info about things like which version of gmp they're using, which compiler etc. then maybe we could make some progress on this issue. I know it's weird, actually i'm using exactly the same configuration (ubuntu version, installed libraries and cpu model) than John Tapsell and it works for him. I've already volunteered givin remove access to my machine to David Johnson so he can try fixing the bug but he said it was not necessary. For the record: gmp version: 4.2.1+dfsg-5ubuntu4 g++ version: g++-4.1 (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) machine: AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ OpenSuSE 10.3 64bit, gcc 4.2.1 The attached patch fixes the problem (better: avoids the problem). After this 3+3 is 6 again on my system. It was ever, but displaying did not work correct. Works here :-) Albert Christian ___ release-team mailing list release-team@kde.org https://mail.kde.org/mailman/listinfo/release-team

I already tried to pass 10,0 without success. Don't know if nan and
inf is correctly interpreted.
Does gmp create a deep copy of the char*? If not that might be the
reason, toAscii() returns a QByteArray and that will be implicitly
converted to char*. However that returns the QByteArray internal buffer
and thus its gone after the call to mpf_set_str. So either gmp needs to
do a deep copy in set_str or you need to keep the QByteArray around
until its not needed anymore.

I hope you're wrong - I would consider this as a design bug in gmp
otherwise :)
