Ubuntu :: Compiling For Multiple Architectures?

Aug 13, 2010

I'm trying to compile some of the gnu utils (the version on some of the computers I work on are terribly out of date). The issue is that many machines share the same filesystem, and I'd like to not have a different executable for each machine. Anyways, I've read that

./configure CC="gcc -arch i686 -arch x86_64 " --prefix=/home/user/bin

should work. But of course it doesn't. apparently -arch is not an argument accepted by gcc.

Ubuntu Multimedia :: Multiple Machine Multiple Display Wall?

Aug 4, 2010

We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.

Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.

I often use the rpl command to make changes to multiple html files at once. For example:

I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.

I tried the coding posted above.

General :: Good Support To Multiple Desktops AND Multiple Monitors

Jun 4, 2010

I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminals in my Linux workstation.Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea).I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example.

My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. All the tutorials I read (like this one) only tells how to use multiple monitors but doesn't answer my question about keyboard shortcuts.Does Linux (Ubuntu 10.04 Lucid Lynx or Debian 5.0.5 Lenny) support this envisioned setup (Different workspaces in a way that keyboard workspace switching only works in the current monitor) ? If so, how?I haven't tested this setup, that's why I'm asking. In this question the user says it works exactly how I want it to behave, can someone else confirm it?

General :: Multiple Servers Or One Server With Multiple VMWare?

Feb 7, 2011

I'm looking at setting up a couple automated systems: Here are a few examples:

* Internal accounting system to download and process emails
* Public web server to visit

I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?

To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.

CentOS 5 Networking :: Multiple Nics With Multiple Gateway ?

Jun 16, 2009

I have a CentOS 5.3 box with three network interfaces in it. Each interface is attached to a separate VLAN and I want traffic to stay on each network segment.What I can�t figure out is why I cannot get each interface to have its own gateway and everything gets sent through the default gateway.The basically takes my possible 3Gb total bandwidth and throws it down a single 1Gb pipe.Then on top of that, if I take down the interface (ifdown) that has the current default gateway,I loose contact to the other two interfaces.When I look at the routes, each one of the interfaces shows the gw as and defers to the default route. So I delete the route and try to add a new route with:

[root@testsan ~]# ip route add via dev eth2

but end up with the error:

RTNETLINK answers: Network is unreachable

[root@testsan sysconfig]# cat network

Software :: C++ Compiling Wx2.8.10 On 64-bit Ubuntu?

Mar 7, 2010

I went from mandriva 2009 32-bit to ubuntu 9.10 64-bit and wx begins to act up..

the simple program from the wx hello world tutorial build fine on my old system, but not my new on. I got the packages installed (wx2.8.10-dev, headers and whatnot)

I've looked around a bit and it seems the compiler is not including the files correctly..

Compiler command:

g++ k.cpp `wx-config --libs` `wx-config --cxxflags` -o morten
Compiler output sample (because most of it is because of first errors):
k.cpp:9: error: invalid use of incomplete type struct wxFrame
/usr/include/wx-2.8/wx/utils.h:50: error: forward declaration of struct wxFrame
k.cpp:12: error: ISO C++ forbids declaration of wxPoint with no type

Ubuntu :: Compiling Libs Under A Different Directory

Feb 21, 2010

I am fairly new to ubuntu. I have to compile some libraries under ubuntu in a directory other than the default directory and then get the shared object libs (.so) libs for building some custome kernels. I created a directory structure as follows:

/home/username/src-<libname> =>here are the source files for the lib. I need to compile

Now I create a directory /home/username/src-openssl and download the source code and untar it under this directory and issue ./configure --prefix=/home/username/build-target --exec-prefix=/home/username/build-target and then make and make install. I was expecting that the shared object libraries created (.so) files should have gone under /home/username/build-target/libs, however I just see only libssl.a and libcrypto.a and not .so files under the build-target/lib directory. For grep also I did the same thing as above however I don't see any lib directory created under build-target directory as I was expecting.

Ubuntu :: Compiling A Custom 64 Bit Kernel With BFS?

Aug 1, 2010

I would like to try and optimize my kernel a bit. Since I am doing this on a fresh install, I don't really care if the os gets bricked in the process, and I am sure I can bring it back if I can boot into a recovery console from the old kernel. So, I followed thispost. I patched it and copied and edited a config file from /boot/, saved it as .config, I tried it several times with both removing and not removing /debian and /debian.master directories from the source, yet I always get the same error when I run "make oldconfig".

$ make oldconfig

*** Error during writing of the kernel configuration.
