I18N: C++ (and C) locales; curr_symbol; and fonts
by Alec Ross 30 Jul '05

30 Jul '05

Can anyone help w/ advice on using the standard C++ locale capability to print currency symbols? I'm using a standard SuSE setup and compiling and running c++ code, using g++ from a shell. In a few simple experiments, I have mixed results in printing the UK pound sterling symbol w/ an English locale (this is OK); the euro symbol w/ a German locale (the character shown is not the euro symbol); and poor results trying to show the Yen symbol w/ a Japanese locale (nothing, or a string ending w/ a Yen symbol, depending on the precise locale used, IIRC). It could well be that there is a fault in my c++ code; but what I suspect most is that I should be using non-default fonts (possibly Unicode, with wide character handling in the c++) for at least some of these currency symbols. I'm sufficiently a newbie to Linux and SuSE that I don't know the best (or any) way to change the font in my default shell, and/or for file handling. (Or any aspects of differences between fonts used to display input from the keyboard, and standard output.) So, can anyone offer useful advice on these issues, or point me at suitable material? TIA. -- Alec Ross

SuSE 8.0: Compress and split a big sized file into smaller files
by robert guru 29 Jul '05

29 Jul '05

hallo, there is any shell command that compress and split a big sized file into many smaller compressed files for example a data file (file.data) with the size of 15 Mega bytes will compressed (by tar command for example) and divided to many smaller files of 3 mega each file (file.data1.zip, file.data2.zip .... ), because i have to email those files as attachments. PS: I would like that the zipped files will be recognized and gathered by windows too (like Win-rare tool).. thanks!! _________________________________________________________________ MSN® Calendar keeps you organized and takes the effort out of scheduling get-togethers. http://join.msn.com/?pgmarket=en-ca&page=byoa/prem&xAPID=1994&DI=1034&SU=ht… Start enjoying all the benefits of MSN® Premium right now and get the first two months FREE*.

Its a reproduction of this bug http://sources.redhat.com/bugzilla/show_bug.cgi?id=801 I was wondering if anyone else has noticed that, or come across the same problem. I wonder when Suse will release a fix for it. Sid

Elf documentation?
by Steven T. Hatton 26 Jul '05

26 Jul '05

I'm trying to get an overview of elf, and I'm not sure what I should be looking at. For example, I found this on the net: http://ou800doc.caldera.com/en/man/html.3elf/Intro.3elf.html I don't, however, see anything similar in the SuSE-provided documentation. I just installed libelf, but I'm not sure what this will do for me. `man elf' provides documentation for the elf.h file. What's a good source for learning about elf? -- Regards, Steven

Re: KDevelop crashes and SuSE QT patches
by Vadym Krevs 25 Jul '05

25 Jul '05

Hi, I'm using KDevelop 3.2.1 under KDE 3.4.1 on Suse 9.3 for x86-64 (installed from supplementary Suse rpms). Fairly frequently Kdevelop crashes when closing multiple files via the "Window-Close All" (see stack trace below) or via "Project->Close Project" or even when switching tabs beween open files. The same used to happen on Suse 9.1 and 9.2 for i386 and x86-64. There are several bug reports for this and very similar issues, http://bugs.kde.org/show_bug.cgi?id=95245, http://bugs.kde.org/show_bug.cgi?id=89278) and the according to kdevelop developers, all these crashes are caused by a QT patch that SuSE is using. I was wondering if anyone at SuSE could have a look at this issue - as this patch is clearly causing a lot of grief to many people.

I don't know if this will make it past the gatekeeper with the attachment. It's a small html file with a table of running some performance measurements on GCC 3.3.5 and GCC 4.0.1.

Qt / SlickEdit Rant
by Brad Bourn 14 Jul '05

14 Jul '05

From my experience on the SuSE platfrom, the fastest / most flexible way to develop software is with SickEdit and Qt. With SlickEdit from 9 to 10, I lost the ability to use slickedit on muli-headed environment. So I still use 9. With Qt4, I lost the ability to use Designer. - Can't add slots to forms - Can't change grid size or snap to value - Can't use buttongroups Most of my apps, I would create a form, add slots for what I needed to code, subclass the form and write the code. done. Now I have to do everything from code. Can't even use the designers preview, because the widgets aren't in the right spot. What the hell is happening? Grrrrrr B-)
