View Full Version : HOW TO: How to compile and install Gnome panel sensors-applet



Zed

I wanted a persistent display of my CPU and hard drive temperatures on my Gnome panel (I tend to work with one maximized window at a time, so I'm not into gdesklets.) The Breezy universe repository offers the xfce4-sensors-plugin, but, for whatever reason, Breezy doesn't include sensors-applet for Gnome. Here's what I did to install it.

First, get sensors (http://ubuntuforums.org/showthread.php?t=2780) working. Don't proceed without this step. Be warned that it's possible to render your machine unbootable (http://ubuntuforums.org/showthread.php?t=41041) if you configure things incorrectly.

There are Debian packages (http://sensors-applet.sourceforge.net/index.php?content=packages) available. I didn't use them. Maybe one or the other would work in Ubuntu; I don't know. This how-to calls for installing the build-essential package, which is a bunch of stuff you only need to compile things yourself. If disk space is tight or you otherwise don't like the idea of installing that much stuff to get one little applet, don't do it.



sudo apt-get install build-essential
sudo apt-get install libpanel-applet2-dev
sudo apt-get install libxml-parser-perl


If your hard drive supports SMART monitoring (which it probably does unless it's really old) and you want to use the sensors-applet to display its temperature, then:



sudo apt-get install hddtemp


When it asks you if you want it to run as a server, say yes. You can



sudo dpkg-reconfigure hddtemp


if you want to change it later.

Then download sensors-applet-1.5.2.tar.gz from Sourceforge (http://prdownloads.sourceforge.net/sensors-applet/sensors-applet-1.5.2.tar.gz?download). (This is the current unstable version; the release version is 1.4 (http://sensors-applet.sourceforge.net/index.php?content=source).)


cd ~/Desktop # or wherever you downloaded it to
tar xvzf sensors-applet-1.5.2.tar.gz
cd sensors-applet-1.5.2
./configure --prefix=/usr
make
sudo make install


You should now be able to right-click on your panel, select 'Add to Panel', and the add to panel window will include 'Hardware Sensors Monitor' with a computer chip icon, under Accessories. Click and drag it to the panel. Right-click on it and select properties to configure it. Here's a picture of mine, on a left-hand-side vertical panel.

tar xvzf sensors-applet-1.5.2.tar


should be "tar xvzf sensors-applet-1.5.2.tar.gz"

Tootal Linux newB here:confused:
I get this error all the time I try to install anything. What do I lack? I tried installing gawk(what is this?). Anyways please help me on what I need to install to be able to compile? Thanks:smile:

That error is basically saying you don't have some packages that are required to make, compile and build.

I assume that you did a


sudo apt-get install build-essential

as per the guide. You may also need to


sudo apt-get install gcc-3.4


To install the GNU C compiler

Thanks for the quick reply
I already installed the GCC 4.0 also installed GCC 3.4 thru Synaptic.

Try re-installing build-essential, that should be it.
I've read alot of posts about "C compiler cannot create executables", they all seem to be resolved using build-essential.

Thanks again Sutekh
Made some changes
Although after trying to apt-get some missing files there is still some? Please help:smile:

Don't do "sudo make install", instead install checkinstall (sudo apt-get install checkinstall) and create a Debian package (.deb) with it by replacing "sudo make install" with "sudo checkinstall". That way you don't need "make clean" in order to remove an installation, "sudo dpkg -r package" is an easier and probably more favoured way. Isn't there checkinstall HOWTO somewhere?

To install the XML parser, run the following command:


sudo perl -MCPAN -e shell

When asked to do a manual configuration, type no

At thecpan> prompt type:


install XML::Parser



Try this.

make had returned bad status, install seems impossible

That doesn't sound encouraging does it? What exactly are you trying to install? For the most part its alot easier to install via Synaptic or a .deb rather than from source.

Everything worked well but I have 2 questions:

1. For some reason my main drive /dev/sda is not listed in the HD tempoptions...just an ide drive that i have in the machine. The sata drive is new and i'm quite sute its SMART enabled.

2. Is there anyway to change the labels that that the panel applet uses? Tem3 is my mobo sensor and i'd like to display that instead of "temp3".

Thanks,

mak

PS: Good how to!

awesome How-To, works for me on my amd64 machine :p

checking for XML::Parser... configure: error: XML::Parser perl module is required for intltool

Did you miss this step?


sudo apt-get install libxml-parser-perl


1. For some reason my main drive /dev/sda is not listed in the HD tempoptions...just an ide drive that i have in the machine. The sata drive is new and i'm quite sute its SMART enabled.

No clue, sorry. What does


sudo hddtemp /dev/sda

do?


2. Is there anyway to change the labels that that the panel applet uses? Tem3 is my mobo sensor and i'd like to display that instead of "temp3".

That one I know. Right-click on the sensors applet in your panel, select the 'Sensors' tab, select right-arrow next to the sensor corresponding to your mobo (it's i2c-sys for me, but this will vary) to drop down its submenu. Then select the Tem3 line, and, then select the label and it'll become an edit box and you can change it. (Don't double-click quickly -- it's like renaming a file in Windows.)

How blind can I be. Too much excited.:razz:
Will update you Zed.:)

BTW I installed from Synaptic the SMART sensors, X-sensor(which is running fine but too large Graphics). Is it just OK?

Great now it is working:)
Although on the "make" command it gave me this errors

main.c:40: fatal error: opening dependency file .deps/main.Tpo: Permission denied
compilation terminated.
make[2]: *** [main.o] Error 1
make[2]: Leaving directory `/home/j813/Desktop/Downloads/sensors-applet-1.5.2/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/j813/Desktop/Downloads/sensors-applet-1.5.2/src'
make: *** [all-recursive] Error 1


(which I just ignored & did the "sudo make install" command) & seem to be working

I just followed these steps and it worked for sensors-applet-1.6.tar.gz, so the original thread may want to be updated with this information.

Are there any sensors besides the temp sensor that comes by default? Where can we get them?

i did everything, but i have a couple problems

one, i have two cpu's that i can choose from (the sensor), cpu (intel) and cpu (amd). The weird thing is, i have an AMD processor , but the cpu (amd) sensor does not seem to work. it just sits at 25 degrees celsius (which i know is not right)

but when i use the cpu(intel) sensor the temperature works actually. Is this normal?

and second, i think that the cpu sensor is off. Right now its showing 40 degrees celsius which i KNOW cant be right. and the motherboard is showing 57 degrees celsius. But according to a different program in windows, it shows that:

Temperatures:
Motherboard 39 C (102 F)
CPU 57 C (135 F)
CPU Diode 67 C (153 F)

how come the cpu/motherboard sensors are wayyyy off?

For some reason I was missing the follwoing dependence: libpanel-applet2-dev
I've looked for it in Synaptic and installed it.

I'm using Dapper and once I've finished the install as suggested, I went to install Panel-sensor on my top panel. But I didn't find it under "Accessories". However, there was a "Hardware monitor" System... Is this the same program??

Either way, I have what I need now! :)

Wow, still works perfectly after 7 years!!!! (with version 3.0, some more dependencies to solve but very easy, just do what the configure step tells you)
Installing and using GNOME instead of Unity and following this guide allows you to use sensors-applet with ubuntu 11.10! (sensors-applet was removed from the 11.10 repo!!!)
