neumoDVB

[satesco]

HI Llew,

Thanks for your installed file. I compared my installed dependencies on Ubuntu with yours, on Fedora,and I notice, I would say, minimal differences. Like, GNU 9.4.0 on mine, and 9.3.0 on yours,my gtk 3.0 version 3.24.20 and python 3.8.10. Then, wxwidget 3.0.5 for me, 3.0.4 for you.
I'm not sure, if these differences influenced the result, because in the end after make -j8, the process ends with error2:
built target libneumowxsvg
make: *** [Makefile:130: all] Error 2,

whilst in your case the result is different, namely:
-Completed 'libneumowxsvg'.
[ 97%] Built target libneumowxsvg
Scanning dependencies of target pyneumompv
[ 98%] Building CXX object src/viewer/CMakeFiles/pyneumompv.dir/neumompv.cc.o

[100%] Linking CXX shared module pyneumompv.cpython-38-x86_64-linux-gnu.so
[100%] Built target pyneumompv
I also note that I installed the dependencies according to your list.
Is it because of them that the installation ended with error 2?
Any advice is welcome with thanks

I'm using the Ubuntu dependencies too for my Mint version satesco.

What does Error 2 refer to? Should be an Error flag further up in the build

 

[satesco]

I couldn't find any .log files in the build folder, actually in any neumodvb folder. After trying again to reinstall neumodvb, I found the same errors, like the ones I've reported, but they seem minor, which I also found in your file (who knows).
I don't know what error 2 is( "Makefile:130")?
I'm not sure if the installed dependencies are compatible with the 5.13.0-35 kernel of my ubuntu?
I also notice that you installed the app in Root. Does that matter?

 

[Llew]

I don't know satesco. I wouldn't have thought it makes a difference.

Error 2 is the error a few lines above, namely "/usr/include/gtk-3.0/gdk/gdktypes.h:143:39: error: typedef"
which seems to be that blessed gtk problem.
Do you have these in /usr/include -
/gtk-3.0/gtk/gtk.h:30: <gdk/gdk.h>
and in /gdk/gdk.h:32: <gdk/gdkconfig.h>

Probably nothing to do with the problem, but then I'm not that clued up when it comes to what errors can throw up - that's for someone with deeper Linux experience

 

[satesco]

Those folders are in the gtk-3.0 folder, but I don't see "gdktypes.h:143:39: error: typedef" .
Probably the differences in file/folders management are due to Linux variants (?!)

 

[Llew]

I don't see "gdktypes.h:143:39: error: typedef"

gdktypes.h should be in gtk-3.0/gdk.

 

[deeptho]

Satesco,
Please stop focusing on this "error 2". It is not your problem (see my post above)

I think what is your problem could be related to having all kinds of old software installed
in /usr/local and which conflicts with newer/other software in /usr. First you had (or perhaps
still have) multiple versions of python installed: one in /usr (the good one ?) and an older one
in /usr/local/

So what probably happens is that a lot of newer software is being overridden by older
things which are in /usr/local for some reason that probably you only know.

Specifically you have some wxgtk development files installed /usr/local, but the rest of your files
seems to come from /usr.

I would advise treating anything which comes from /usr/local with suspicion on your computer.
Search for anything python, gtk, wx... related in /usr/local and remove it and see if that helps.
An easy way to remove everything is "mv /usr/local /usr/local.saved". Note that this could cause
problems.

Also, note that putting things in /usr/local is not a problem in itself, but it is a problem if you have a mixture
of versions installed in /usr and /usr/local. So the first thing is to check if this is happening or not.

 

[Satspot]

Could I suggest creating a new partition on your drive, doing a fresh install of whatever flavour of Ubuntu you use or preferably Fedora the flavour that @deeptho used to create and test his project and try your build from there. As was mentioned you now have artefacts of possibly older programs and other kludge cluttering up your install. As you know you can simply switch between versions at boot time. It would be a lot simpler than spending countless hours sifting manually through folders trying to get this to work.

 

[deeptho]

Installing from scratch is a bit excessive to solve what is probably a simple problem.
So: remove all conflicting files in /usr/local. They are easy to spot in the log files.
Then do not forget to rerun cmake (so restart the build process from the start)

 

[satesco]

@deeptho,

After removing python2.7 and saving /usr/locale.saved, as you advised, I managed to install neumodvb without any error. But that didn't help me to start neumodvb because the wx module is missing. I also installed wx.glcanvas but without importing the module( how?), as shown in the screenshot.
I probably have to reinstall wx(widget), but in order not to spoil what I have done so far, I am waiting for your advice to solve this last error.
I imagine how busy you are, but in case it is necessary to see what I have done, I provide you the file with the installation of neumodvb.
I really appreciate your help,actually because you developed this application

 

[deeptho]

Satesco, if dependencies are missing, just install them, but be careful to read the installation documentation,
so that you install the correct ones.

 

[Llew]

satesco, I don't want to cloud the issue by unhelpful suggestions; all I can say is those Ubuntu dependencies are all I needed to build my neumoDVB ( admittedly after some hiccups along the way (see early posts )

Glad at least that you built to 100%

(FWIW, My distro is Linux Mint 20.2, based on Ubuntu 20.04)

Your interventions on this thread have been welcome, even more so for those trying to install the application for the first time.Thanks for that
Finally I managed to see the graphical interface of neumodvb. For now I'm trying to configure lnbs,cards,etc.
I'm a bit annoyed that the frontend list in the app doesn't seem to match the adapters list in the terminal, because setting an lnb on one card or another doesn't match...
For now I'm content with that for now. Tomorrow is another day... But I don't refuse suggestions on card configuration. Of course I also consult the Neumodvb page on Github.
A passing remark, when I hit spectrum, the app crashed.

 

[deeptho]

Maybe you should install the blindscan drivers before further testing?

 

[Llew]

I'm a bit annoyed that the frontend list in the app doesn't seem to match the adapters list in the terminal, because setting an lnb on one card or another doesn't match...

I get a similar problem occasionally with my August or PCTV DVB-T/T2 sticks - when I reboot, they can appear randomly in the adapter list. Not that we can use them for the DVB-T services yet...

A passing remark, when I hit spectrum, the app crashed.

I have the occasional crash with that too. It's early days with the app, I'm sure as deeptho finds bugs and put them in Github, we'll see things improve over time.

 

[Llew]

An example of blindscan speed differences between neumoDVB's spectrum scanning and, for example, IQ Monitor's, using the TBS6903X.

Here's a blindscan of 4.8E's horizontal TP's between 11.700 to 12.700Ghz, using neumoDVB - 33 scanned, 14 locked in 7m. 37s. (A zoomed chart below to show some marker details, the chart restricts full marker information).









IQ Monitor, (?) scanned,16 locked in IH 46M



So, neumoDVB will do a fast blindscan compared to IQ Monitor, but the latter provides more TP detail in the chart. Of course,it's easy enough to click on individual locked TPs in neumoDVB's scan results for the information, or go to the DVB-S Mux Section.

 

[satesco]

I finally managed to see the first images with neumodvb but with a big price, namely, the resolution of the monitor has changed. Exactly what I was afraid of. The deeptho links for installing drivers with ./sh do not work, plus I did not find the kernel 5.13.16 for ubuntu 20.04, recommended by him. This forced me to install the drivers with the command "make allyesconfig".
There would be no problem with this if the graphics resolution could be changed easily and safely,but my previous attempts, and others users, to fix the resolution fail every time.This time I can't change it either. Maybe you have some idea how I could fix it.
I hope I don't have to go through the whole process of installing drivers from scratch. Even if it is a hobby,as Deeptho rightly said,time has no patience from a certain age (only in youth do you have the feeling of eternity in front of you ). Not to mention other projects I have in mind.

 

[Llew]

I did have video resolution problems with certain kernels I tried before the one I use now. It's one I found after discussing the problem over at Rick's wildfeed site (linux blindscan for TBS cards)
In the event, I downloaded bill murphy's kernel 5.9.0 debs, which cured the problem (for me, at least. You might consider trying that, but I can't guarantee it'll solve your problem )

deepthought · master · bill murphy / kernel-dvb-pkgs · GitLab

some precompiled kernel deb-pkgs for v4l-updatelee, and deepthought's tbs media drivers...

[satesco]

Hi Llew,

As usual, you are a reliable colleague With the help of your link, I managed to use the kernel 5.4.0-1069 to get back to normal resolution. You saved me a lot of time and headache to be able to work with neumodvb installed, for which you have my friendly gratitude
Now I'm trying to manage on my own, I hope, to work with deeptho's app

 

[Llew]

Sometimes we can go through many twists and turns before we arrive at a solution satesco.

You've helped me before with various card etc. problems over time, so glad I could help now
