[gentoo-user] gdb debugging of small system built with catalyst
Hi, I have few directories each contains C++ code, and is mapped to a local private ebuild. So I need to install few projects that depend on each other. On the target machine I have gdbserver running. When connecting to gdbserver, the links to the sources is /var/tmp/.../../file.cpp. My problem is that I need to debug all programs together, and the sources are in catalyst's tmp working directory. I can use 'directory' command in gdb to change the search path of the source files, but doing it to few projects is cumbersome. I can compile the source with -g3 and embed the sources there, but didn't try that as I heard it is unstable. At the end I need to provide a way to allow programmers to use Eclipse with all the directories sources to debug all projects at once. Is there other method to do this and integrate it to Eclipse? For start no need for eclipse, I need to debug from the command line or vim. Regards, Kfir

[gentoo-user] wicd
So, after having plenty of trouble working on getting Gentoo set up to work with my new laptop, I'm finally able to run 'iwlist wlan0 scan' and see the 15 or so cells in immediate area. Rather than going straight wpa_supplicant or using NetworkManager on this machine, I thought I'd give wicd a try. Trouble is, wicd, for whatever reason, isn't seeing any any of the cells. If I run wicd-cli --wireless -l, I get a list's headers, but no observed networks. If I run wicd-cli --wireless -S, I get no output at all. The page on gentoo-wiki.com for wicd[1] talks about a few configuration files for manual configuration, but those aren't present on the filesystem, and there are no manpages for them.

[gentoo-user] Acroread DRM Bug?
Hi, our public library uses Adobe Digital Rights Management. That means you download a paper/book and open it with acroread. It used to work fine with gentoo ~amd64 but not with ~x86 and x86. (I assume it works with amd64 as well, can't just test it) Acroread always crashed, when I tried to open a drm-protected document on x84-installations. The reason is, that acroread (acroread-9.4.2) is installed as binary, but dynamically linked and when you open a drm-protected document, it tries to load the non-existing library /usr/lib32/libidn.so.11. To reproduce: in xterm: $ export ACRODEBUG=1 $ acroread now open drm-protected document dlopen: libidn.so.11: cannot open shared object file: No such file or directory This library is part of app-emulation/emul-linux-x86-baselibs-20110928 which is usually installed with non-x86 installations. So I installed emul-linux-x86-baselibs and did set a softlink from /usr/lib32/libidn.so.11 to /usr/lib. It works fine. But lately I ran into problems after upgrading gcc. I couldn't emerge qt-gui anymore. Actually I had to remove the link, rename /usr/lib32 and reemerge gcc. Then it was possible to emerge qt-gui. Any suggestions? Could there be a library on x86 installation, that one could use? Could I hide the library from ebuilds other than acroread? Should I file a gentoo-bug-report? Greetings Michael
[gentoo-user] I'm in a Pickle
Happy Holidays, Everyone, To lead into the problem I am experiencing, I will let you know about an issue I've been having with my desktop (writing this from my laptop). Every once in a while, when the screensaver kicks in and then, the monitor goes on power save mode (something inherent to the monitor), the screen locks (I have not set it to do this) and the only way, I can get the computer going again is to reboot it by holding down the power button. This is annoying, but has not caused an issue until today. Today, I was doing a world update and the screen locked - I still had my KDE desktop up, but couldn't open a window to kill any processes or anything. So, I held the power button to cause a reboot. The computer booted okay and gave me my login screen, but neither the keyboard nor the mouse work. Any ideas?
