I'm not an expert in Linux but I can hack my way around. I'm going through the documentation at;
http://oss.oetiker.ch/rrdtool/doc/rrdbu … tml#___top

I know from a previous post that freetype & libart need installed.

I can follow the instructions but don't know how to install MAKE. I know how to use shell scripts somewhat but when it comes compiling, etc. I'm still learning.

Anyone got a good step by step guide on how to do this.

I'm working on using my DNS325 as a more detailed logger for a TED5000 to track the energy usage in my house. So far I've written a shell to get the minute data for an entire day and convert it into a file that is setup so rrdtool update can get it into the rrd database.

Now I need to get rrdtool working on the DNS and start making a few graphs.

I will try to compile it and give you a package.

Memiks, that would be great! What FFP version will you compile for? I'm hoping for 0.7.

The newer rrdtool versions depend on pango and cairo for text management and graphing, so porting that to FFP is a lot of work. Hats off to you if you can provide that to the community.

memiks · 2012-11-28 10:32:16

I will compile for ffp 0.7 eabi not oarm

ottsm · 2012-11-30 08:15:50

Hope you can do this, thanks.

memiks · 2012-12-03 11:28:14

Hello,

My NAS currently build ghostcript to compile libspectre to compile cairo to compile pango :x

After that I must be able to compile rrdtool.

Memiks.

memiks · 2012-12-07 14:40:53

To compile pango last version I need to build new version of glib. so I currently compile glib.

memiks · 2012-12-11 11:21:41

glib 2.35.2 is built, I will compile cairo / pango and rrdtool...

memiks · 2012-12-11 14:23:45

Hello, I just compiled rrdtool for eabi. could you test it and give me a fallback please ?.

In order to compile it I add these packages to my repository :

32d26bc2fb54e3151a3b10029b310a0e cairo-1.12.8-arm-1.txz
473b0116a2dbd50121f48097b2e5a829 fontconfig-2.10.2-arm-1.txz

Memiks, you are the greatest! ;-)

Just a very short report about my first trial on Medion NAS, FFP 0.7 arm:

In addition to the packages you listed, rrdtool requires several more:
libxml2-2.7.8-arm-1.txz
libpng-1.4.7-arm-1
and others, my screen buffer is too small to get back to all the missing libraries that "rrdtool create" reported. "slacker -Ui" is your friend in finding and installing these.

Loading a few test data into a rrd database with "rrdupdate" was easy, creating a graph with "rrdtool graph" first gives this fatal error:

Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.
This probably means there was an error in the creation of:
'/ffp/etc/pango/pango.modules'
You should create this file by running:
pango-querymodules > '/ffp/etc/pango/pango.modules'

After creating the missing file with the command listed, a graph (png) gets created, but these warnings are displayed:

Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='common'
Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'

The generated graph contains no text, just little boxes where characters are supposed to be. Will have to investigate further, probably will have to run "fontconfig" or something similar.

memiks · 2012-12-11 17:50:09

Ok the system does not have fonts installed, I will check how I can add a font packages for ffp.

For
libxml2-2.7.8-arm-1.txz
libpng-1.4.7-arm-1.txz

I already have them on my system So I did not compiled them...

The error of pango is "usual" since the package does not include the pango.modules (specific on each installation).
But yes I forgot to talk about that...

I will check fonts and come back soon

Memiks.

memiks · 2012-12-17 17:29:52

Hello could you try this :

create a folder in your user home directory:

mkdir ~/.fonts/

go to .fonts directory :

cd ~/.fonts/

download the font package:
wget http://ffp.memiks.fr/pkg/truetype.tar.gz

untar it:
tar xf truetype.tar.gz

delete it :
rm truetype.tar.gz

update font cache:
fc-cache -fv

restart rrdtools.

Best regards,
Memiks.

rspitz · 2012-12-27 00:16:08

Hi memiks,

sorry for late reply, didn't get around to testing this earlier. I hope you had enjoyable christmas holidays.

I downloaded your font package and installed as instructed, now I can create rrdtool graphs with readable text. Thank you for your support!

There is just one problem remaining: I'm using the "root" account on my Medion NAS, since I haven't been able to figure out how to create another user account for logging in via ssh. The accounts created for file shares are refused to login via ssh. The contents of /root don't survive a reboot, so the fonts will be lost. As a stopgap measure, I put the truetype directory into a persistent place and created a symlink in /root, which I can recreate in a startup script. Would you recommend another solution?

Regards, Richard

ottsm · 2013-01-18 05:28:49

I've been out for awhile. I tried this. Getting the following error;
can't load library 'libfreetype.so.6'
I can't find this in the repository?

ottsm · 2013-01-18 06:30:56

Ok, was missing;
freetype-2.4.8-arm-1.txz

This seems to have fixed this immediate problem.

ottsm · 2013-01-18 21:30:55

OK, I was able to create an RRD database, however when I go to graph it I get the following error;

(process:21228): Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.
This probably means there was an error in the creation of:
'/ffp/etc/pango/pango.modules'
You should create this file by running:
pango-querymodules > '/ffp/etc/pango/pango.modules'

(process:21228): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='common'

(process:21228): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'
490x148

I did the above truetype font instructions.

ottsm · 2013-01-18 21:41:58

I guess I had to update the pango cache, now it seems to be working;

pango-querymodules --update-cache
