- Add more exact values for sin() and cos() and avoid floating point underflow by, in approximate mode, checking against the value of pi
- Always input decimal separator sign on keypad separator press
- New units: typographic units, pouce, pied du roi, grams of TNT and tons of TNT
- New functions: lambertW(), addDays(), addMonths(), addYear(), addTime(), isNumber(), isReal(), isRational(), isInteger(), representsNumber(), representsReal(), representsRational(), representsInteger()

 build issues

 
 by jsantiagoh on: Jun 3 2005

I'm using kde 3.4.1 and qt 3.3.4 and couldn't compile qalculate-kde because i get lots of std::string to QString convertion errors, i have no idea about qt programming but it seems that it need some kind of convertion, I wonder if it's just me having this issue. The autor seems to have tested it with the same version of the libraries, that's what's confusing me. Ah and got some problem with the CNL in the configure, easly solved. BTW libqalculate and qalculate-gtk are working fine.
Great news there is a qalculate-kde, i use this app a lot and i love it. Hope can make it work.

Thanks

I'm a bit confused with QString and std::string. I used QString::ascii() for conversion but I sometimes forgot it and it worked anyway (in some cases). I guess I should go through the code and make sure that I use QString::ascii() everywhere.

I expect there will be lots of problems in this first version that soon will be fixed.

oops. I'm sorry. I see now that the problem was in the other direction (std::string -> QString). Can please post the error messages.

The list of archives whith the issue is long, i'll post a bug in sf with an attached text list.

I also get:
checking for CLN - version >= 1.1.0... no
*** Could not run CLN test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means CLN was incorrectly installed
*** or that you have moved CLN since it was installed. In the latter case, you
*** may want to edit the cln-config script: /usr/bin/cln-config.
configure: error: No suitable installed version of CLN could be found.


in configure, even when libqalculate and qalculate-gtk where compiled and installed wihout problem.

I didn't look into it, just supposed that was a configure.in error detecting CNL so i removed the CNL check in configure.in, did autoconf; automake and then ./configure && make.

I'll post the config.log in bug.

I have uploaded a fixed tarball replacing the old.



The email will arrive sooner or later. altern.org seems to have a bit too much downtime and I have now changed my e-mail address on kde-apps.org.

In the screenshot, the window title font is "Script MT Bold" and the menu font is "Copperplate Gothic Light" (both unfortunately commercial fonts included in ms office). On the desktop "French Script MT" is used and the rest is "Bitstream Charter" (Type1).

emerge qalculate-kde
or
ACCEPT_KEYWORDS="~x86" emerge qalculate-kde
to get the much improved 0.8.1 version

First of all, I have to say that your program is a very useful calculator.

I use the KDE version. Would anyone make an icon for this great app?

Do you like or dislike Ubuntu Unity?
 Yes, unity is alien technology!
 It is less confusing than Gnome 3 default, shell.
 Granny thinks it is much more usable than Gnome 2
 Canonical is embarrasing itself with this split project
 Gnome 3 default shell is much better
 I dislike Unity, Gnome 3 default shell is alien technology!
 None of the above, I like the 2Gb for free and Apple alike behavior. Will post a comment instead
