checking for qsort... no configure: error: No qsort library function. configure: error: could not configure Berkeley DB I have db-4.3.27, db-devel-4.3.27, db1-devel-1.85-89, db1-1.85-89 installed.

Cygwin : How-To cut & paste
by Maura Edelweiss Monville 08 Jun '05

08 Jun '05

I wonder whether there is someone who has some experience at installing and using Cygwin on a Windows/XP box to run graphics applications remotely on a Linux platform ... I did that recently. When I run Cygwin X-server it pops up an xterm taht I use to X-connect to the remote Red Hat machine. Luckily I can run remotely all the graphic applications I need and have them display on the Windows box sitting on my desk ... But there is a typical X feature that I cannot get. It's the common cut & paste that does not work even inside the single Cygwin xterm... Even ohn the Window machine some sort of cut/copy & paste is possible through the drop-down menus fired up by clicking the mouse rightmost button Can anyone help me with taht , please ? Maura

svn ps ignore "semantic.cache" . rejected by server?
by Steven T. Hatton 08 Jun '05

08 Jun '05

I'm using an svn configuration very close to the one described in /usr/share/doc/packages/subversion/README.SuSE. I saw in the online documentation that I could set an ignore property on a directory, and it vaguely suggested that this should apply recursively to the subdirectories. So I did `svn ps ignore "semantic.cache" .' on the root of my current project. When I tried to commit it with `svn ci -m "set ignore semantic.cacne on ."', I received the message: "Sending . svn: Commit failed (details follow): svn: Your file or directory '' is probably out-of-date svn: The version resource does not correspond to the resource within the transaction. Either the requested version resource is out of date (needs to be updated), or the requested version resource is newer than the transaction root (restart the commit)." What I want to do is apply this property to the entire project tree. I see there is a way to create a per-user ignore list in the ~/.subversion directory, but that really isn't what I want. What am I doing wrong in setting this property? -- Regards, Steven

RE: [suse-programming-e] Detect overflow when adding 2 unsigned int

xemacs question
by Jerry Feldman 06 Jun '05

06 Jun '05

I frequently use emacs and xemacs for development. Recently, I found that on xemacs, when receiving diagnostics, the display window displays the raw VT200 escape sequences. GNU Emacs does not display the raw sequences. Obviously this makes xemacs somewhat unusable for development. There is probably a setting somewhere, but I have not found it yet. ----------- here is what it looks like: [1;31mfoo.cc:[0m[1;31m73:[0m[1;31m error: (Each undeclared identifier is reported only once for [0m -- Jerry Feldman <gaf(a)blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9

db, db1, db4.0, db4.1 What do I really need?
by Steven T. Hatton 04 Jun '05

04 Jun '05

On the SuSE 9.2 DVD there are 4 different versions of Berkeley DB. Add to that, at one point I installed my own because the ones available on the version of SuSE I was running at the time didn't support the software I was trying to build. Using YaST I removed all the db versions that didn't result in a conflict. That left me with db1, and db (which I believe is db4.2.x). I have the development rpms for both the db1 and db installed. Has anybody encountered problems or conflicts that I'm likely to run into by removing the other versions? I know I probably need to rebuild Emacs, Xemacs, Qt4-snapshot, KDevelop, and r++ pre-prerelease. But other than that, I don't beleve I have anything I've built against Berkeley DB. -- Regards, Steven

C++ sorting using STL sort()
by Filippos Papadopoulos 03 Jun '05

03 Jun '05

Hi. In my program i am trying to sort a deque using STL sort algorithm: deque<double> q; /* fill q with some doubles*/ ... /* sort */ sort(q.begin(), q.end()); The above works OK. The problem is that now i want to have the following deque: struct rrTask { double C; int tid; }; deque<rrTask> q; /* fill q with some rrTasks*/ rrTask rt; rt.C = A_DOUBLE; rt.tid = AN_INT; q.push_back(rt); /* Try to sort q !!!*/ sort(q.begin(), q.end(), rt.C); The above seems to be wrong. My intention is to sort q using rt.C field as the sort key. What is the right (and easiest) way to do this? Thanks.
