Re: [wsjt-devel] Raspberry Pi

[Greg Beam]

Hi Paul,

I can't speak for others, but no offense taken here.

Following Bills advice clearly demonstrates the difference between 
Single-Thread (1 core), and Multi-Thread (-j x ) compiling, e.g. 
resource consumption, as $(MAKE), when called without the -j operator 
defaults to Single-Thread, e.g. 1 core.

Depending on how you installed JTSDK will determine how to resolve this 
going forward if you plan to continue using the package to build WSJT-X.

If you installed the JTSDK package via my Launchpad PPA, you will need 
to edit the jtsdk-wsjtx build script setting the variable JJ=4 to JJ=1. 
You can experiment with this and may be able to set JJ=2 or 3 cores. It 
all depends on what you have running at the time when you invoke the 
build as to what you can use.

If you installed JTSDK from the source tar.gz package, use the option 
--disable-parallel during the configure stage to disabled Multi-Thread 
compiling. This is why the option ( --disable-parallel ) was added, to 
facilitate compiling on low resource systems without maxing out 
resources. Example:

./autogen.sh && ./configure --disable-parallel && make && sudo make install

At that point, your builds will use (1) core rather than all available 
cores. The builds ( WSJT-X and / or Hamlib3 ) will take significantly 
longer to run, but should finish.

WSJT and WSPR JTSDK build scripts *do not* employ the -j operator due to 
the fact Python3 F2PY does not readily provide for parallel processing. 
Sections of the builds could use the -j operator, but it would be a 
complication that is really not really justified as the WSJT and WSPR 
builds are rather quick as is.

Hi Paul,

no offence at all and glad you have the build completed now, thanks for 
the update.


The issue was almost certainly that the JTSDK uses -jN where N is the 
number of CPU threads, that probably exceeded the VM limit for the 
process. It will be interesting to hear what success you have with 
WSJT-X on the bands and modes you intend to try.

At the moment there are the three choices .

I've moved the shack computer over to a ARMhf , Odroid XU4, as I'm fed up with 
the SATA problems

it reports no drive

Drag the damn thing up on to the bench and swap the HD on to another SATA

Now ARM devices have reached the point where they are seriously useful . mainly 
thanks to the

Hi Richard,

a lot of work has been put into resolving issues with Hamlib, we push 
changes upstream to the Hamlib team but there is a lag since they have 
their own release schedule. They have recently released v3.0 and v3.1 is 
coming soon. With v3.1, at least as far as WSJT-X is concerned, the 
minimum content we need will be in the official Hamlib release and we 
can go back to using the shared libraries. This still relies on the 
Hamlib package being in the distribution repos. so the roll out will 
take some time. Fortunately all our *nix users keep up to date with 
distro versions so the switch to the official Hamlib release should not 
be too far away.

With respect to a version without Hamlib, for almost all users this is a 
non-issue as they use a pre-build package with Hamlib already included. 
On WIndows this is virtually a necessity. With WSJT-X we use Hamlib for 
hard wired PTT control even if it is not used for CAT, this could be 
different but the code has to be written if that is going to change.

If there is demand for a version of WSJT-X without a Hamlib dependency 
then I will consider adding a configuration option to do so but it is 
not just a case of not calling Hamlib as PTT control currently relies on 
it. It is worth noting that probably 95% of WSJT-X users rely on Hamlib 
being used by WSJT-X. Your problem with the JTSDK build of Hamlib may be 
a JTSDK issue, it may be a Hamlib configuration issue. Have you tried 
building Hamlib directly? On *nix systems the JTSDK is a pretty thin 
layer and building both Hamlib and WSJT-X is straightforward once you 
have the required dependencies installed.

I suspect you are taking a rather VHF/UHF terrestrial view of the JT 
applications, please remember that there are thousands of HF users where 
rig control is essential for dual mode JT9+JT65 working and many EME 
users who use the Doppler correction facility that also relies on rig 
control features. The fast mode support also has some capabilities that 
benefit from rig control like random MS working with operation on a 
different frequency from the CQ frequency.

Hi Richard,

I will try and address the many issues you raise there.

We understand what you are trying to do but please listen as well as 
tell. The issue with "unauthorized" distributions is a long standing one 
where some who monitor this list and learn how to build WSJT-X like to 
feed the constant demand for the latest and greatest tweaks to the 
application. We are quite happy with those who do that for their own 
consumption and happier still if they keep up to date and feedback their 
input so long a it is focused and helpful. Unfortunately we also get a 
lot of "such and such build doesn't work, it's not good enough, fix it 
NOW!". When the build in question is one of the developers work in 
progress being shared with other developers, not expected to work, a 
step on the way to a future enhancement, it becomes very wearing and 
consumes scarce development resources that are much better spent on what 
they were trying to complete before the interruption.

You are clearly not in the above category but excuse us if we ask that 
all honour the GPLv3 licence that covers WSJT-X and refrain from 
offering binary distributions without permission from the copyright holder.

Personally I think Greg went a bit far and it may seem like he is trying 
to stop you helping Paul. OTOH I can understand his frustration as both 
you and Paul seem to be ignoring the good advice on how to resolve his 
issue. The underlying message from Greg is that WSJT-X builds on the 
Raspberry Pi2 are just fine, several users have completed them and are 
running the application. The errors are simply due to resource limitations.

With respect to the errors, can Paul or anyone who is trying to help 
him, give us some feedback. Is he doing a parallel build (-j)? Has he 
tried a sequential build (no -j)? Has he tried increasing the virtual 
memory limit for the process running the build? Has the issue been resolved?

With respect to Hamlib, WSJT-X is build with Hamlib support, with HRD 
support, with DX Lab Suite support, and on Windows with OmniRIg support. 
You also have the option to select "None" for CAT control if you do not 
have a rig with CAT capabilities. What is your problem specifically?

With respect to WSJT, the development focus has shifted to WSJT-X and 
MAP65. These two applications will probably provide all the best 
functionality from WSJT and WSPR but this is an evolutionary process and 
it takes time. The main interest of the development team is 
experimentation and sharing the results of their labours with the 
community. WSJT is maintained but it does not get the volume of input 
that WSJT-X currently gets. There are only so many who have the time, 
skills and willingness to contribute at the development level and 
working on all the applications at once is not possible.

One of my goals in my early contributions was to make building and 
packaging across at least Linux, OS X and Windows seamless and possible 
with every release. I  chose to do this with WSJT-X which is why WSJT-X 
has much better cross platform support than the other applications which 
rely on Joe doing the builds and maintenance himself. If you want to 
help with packaging WSJT and helping with maintenance and enhancements 
then do that rather than complaining that packages are not being produced.

Where was this question asked and what does the WSJT package version in 
Debian / Ubuntu have to do with the OP's problem / question? Answer --> 
Nothing ( another literacy problem maybe ). Debian makes their own rules 
for packaging, it's called the Debian Policy Manual (

policies, by all means, take that up with them. I seriously doubt anyone

Ubuntu Mate is fine.

Try changing working directory to the build tree root and doing:

   $ rm CMakeFiles/wsjtx.dir/plotter.cpp.o
   $ make plotter.cpp.o

and see if the ICE recurs.

Re: [wsjt-devel] Raspberry Pi

Hi Richard,



This is ill advised for a number of reasons.

>

>   files after the build are essential to running wsjtx I make a built tarball 
> available."
>

Just to name a few:

[1] Joe has asked ( on more than one occasion ) that we not 
re-distribute unofficial binary packages, this would clearly be an 
unofficial set of binaries.

[2] Building packages destine for redistribution should only be done in 
a clean / repeatable environment ( chroot or equivalent ). Ones personal 
workstation hardly meets that need unless your using a chroot tool set 
like Cowbuilder / Sbuild / Pbuilder (for Debian based systems) or using 
a purpose built server like Launchpad (Ubuntu).

[3] WSJT-X prebuilt ARMv7 packages are available in PPA form at present, 
however, they are for v1.6.0 GA Release only due to item [1].

[4] Simply transferring a pre-built set of binaries sets up the user for 
failure. There is a reason why a system package managers should be used 
for installation by non-developers. Even using dpkg will not properly 
resolve dependencies on a new System Installation.

[5] Your more than welcome to create a PPA for development versions, but 
again, see item [1]. I removed all WSJT-X v1.7.x builds from public 
access due to item [1].

Re: [wsjt-devel] Raspberry Pi

[Greg Beam]

Hi Richard,

His problem is during the build not after. If he's installed JTSDK he 
has all the runtime files he needs. Likewise, if he's installed WSJT-X 
from either the formal release .deb ( using Gdebi etc) that would also 
resolve the runtime deps.

There is already a method in place for producing WSJT-X Tarballs, it's 
the WSJT-X superbuild script, Bill maintains the scripts in the repository.

I've tested WSJT-X builds via JTSDK on RPI2 (Raspbian ~ Debian Jessie 
and Ubuntu Mate 15.10), the builds work as expected when the right 
resource allocation is setup.

If you can't get it to build on the rasp Pi2 , which IMO it should, if someone 
tells me which files
after the build are essential to running wsjtx I make a built tarball available.
The only difference between the raspPI2 and the Odroid C1+ is the quad 
processor runs at 1.6 GHz
compared to 900 MHz for the R PI2, same RAM 1 GB.

Re: [wsjt-devel] Raspberry Pi

Hi Paul,

More than likely you've run out of system resources.

I would create a swap partition if you don't already have one (at least 
1GB to 2 GB) and you may want to edit /usr/bin/jtsdk-wsjtx to use only 
one or two cores rather than all 4 cores.

Hi Paul,

it is not currently being worked on. In general there are two related 
issues with using IQ data, firstly it has to be "demodulated" and 
secondly the mode and frequency of demodulation needs to be set. These 
equate roughly to setting the dial frequency and mode on an analog rig. 
Most receiver implementations that provide IQ data have some sort of CAT 
interface to set their LO frequency and a separate SDR application is 
needed to demodulate to audio. AFAIK all these SDR applications provide 
a CAT interface that emulates some analog rig. Therefore running an SDR 
application meets all the requirements for WSJT-X.

I suggest that you investigate using HDSDR or similar as an intermediary 
between the receiver (and transmitter) and WSJT-X. We have made 
allowance in the WSJT-X/Hamlib sources to make them work with HDSDR when 
the TS-2000 rig type is used. You cannot use split operating for 
JT9+JT65 dual mode but that should not be necessary with an all digital 
audio chain and the ability to select 4kHz wide filters for Rx and Tx.

I use dttsp/sdr-shell/jack running on Mint linux for this purpose.

It works well.

HI Edson

I tried to simplify it as much as possible, may be too much, but I was under 
the impression

that the originator of the question may not of understood the full process.

BTW I still use dttsp and SDR-shell, IMO it still is one the best for detecting 
the presence of a
signal below ear detection threshold.

I'm not that sure that IQ software is needed for using a softrock with wsjtx

The output streams form the softrock are audio,just one stream 90 degrees out 
of phase with the
other.
The width of the frequency displayed on a SDR fed from a softrock depends on 
the bandwidth of the
audio card and the sampling rate. as the LO is not being swept the content is 
stable.
So if you then filter one of the streams, it doesn't matter which , you will 
see whats in the
bandwidth of that filter
So Just connect just one of the outputs of the softrock  in to the audio input 
of the soundcard, 
and as far as I'm aware it will work fine with wsjtx, remember you will have to 
tune the softrock
as you would a normal receiver.
You can feed a SDR with just an single audio feed and you will see the local 
ocillator and a
positive spectrum on the right and a negative on the left, using a I input 
allows you to remove
the unwanted sideband , ie the negative image to the left. or vice versa if you 
select that.

All the softrock is , is superhet Rx with a DC IF, the output is DC to what 
ever the upper audio
freq response  ( as a microwave merchant I regard anything below 100 MHz as DC 
with some ripple !)

The audio output is exactly the same ish as taking the the audio from a 
Receiver post demodulator,
ie audio.

Just connect it and select either one of the audio o/ps from the softrock.

hi Nick
That may well work on a Rasp PI2/PI2 clone , sdr-shell is QT4 and Franks dttsp 
shouldn't grab too
much of the resources, there are later versions where core to shell are usable 
with a network
connection between. there is a separate yahoo group for this.

Richard,

I'm afraid this is incorrect. If you use only one of the channels and run a
real to real FFT on it you will see a mirrored spectrum. The negative
spectrum will be an exact mirror of the positive one. In order to see
negative and positive frequencies you will need both audio channels (I and
Q) and run a complex FFT.

Compiler ICE messages are sometimes due to resource limitations. If you 
are using a parallel build (-j) then try without it. Try increasing the 
process virtual memory limit. Aside from those it may be simply a 
compiler defect, check for updates.

Paul look at the last long line during the compile, and the couple of lines 
afterwards.
In that you should be able to see it cant find a lib or file.
then try installing that lib with the -dev suffix.

Now if you have another computer running linux, one of the debian variants, 
mint ,ubuntu ect
open synaptic and search with the filename that was in those last lines.
When you see the results make a note of those with that look the same with a 
-dev on the end of the
filename.
Then go back to the PI and use apt-get to install the missing lib, and try the 
compile again.
There apt CLI commands to do similat, see man apt and man apt-get.
I've guessed you are running raspberian .

Hi Edson
with one of the PI2 clones you can already use a serial connection to the USB 
port of a tablet
which gives display, keyboard & touch screen.
So using wsjtx portable is very possible, and back packable.
It puts a whole new aspect to microwave roaming in the US, SOTA and other 
portable activities.
With smart devices where do you draw the line between smart phone and tablet,
the only difference between a 5" smart phone and a 7" tablet is likely to be a 
USB and HDMI socket
This whole area is moving very fast, and it would a shame if the opportunity to 
make wsjtx with
fast modes available to all at low cost.
Especially when to do it would require very little extra to be done as ARMhf is 
well catered for

Hi Richard,

Yes, but that is a native ARMHF environment (Ubuntu Mate armv7 / Debian
- Raspbian etc ). What Bill is after is a cross-compile-setup, say Linux
amd64 base, then cross compile for armv7.

But if you want to open WSJTX up to everyone with a tablet cross compile and 
hope wont work.
The old argument that tablets cant be used due to audio drivers is extinct.

Hi Greg
The disadvantage of cross compiling is you still need to test it
If you run a linux machine with QEMU running a ARMhf platform, you can write 
the code on the linux
machine and test it. then export the source code to the QEMU Virtual machine, 
compile and test.
Moreover, you can check that it will run within the constraints of the ARMhf 
typical SBC.
It has the advantage that it improves the code written.
When the first PCs came on the market , you had to be careful to make your 
coding efficient and
lite,
then came bloatware and that all went out thru the window, why do something in 
a few lines of
efficient code when you can visually do it taking ten times , often more, space.
Its all marketing, the bigger it is the more you can charge, it doesn't matter 
what the commodity
people equate size with value.
Take a straw poll on what people consider better value for the same price a 
piece of software 1.5
GB or one 200MB, they will think the the 1.5GB is better value as they are 
getting more bytes to
the buck.
Therefore, IHO, its better to use a QEMU VM on a linux host and know your code 
works, than to just
cross compile and hope it works.

Hi Richard,

You say:

"The disadvantage of cross compiling is you still need to test it"

Are you implying that build on the target means you don't need to test, 
that doesn't sound right to me!

We leave all the cross platform differences to the compiler and Qt 
teams. As far as WSJT-X is concerned the source code is identical on 
every platform except for some trivial differences about file system 
layouts but they are operating system dependent rather than hardware 
dependent.

I have always used cross tools with the 'install' target sending the 
built product to a network device that is shared with the target (or on 
smaller targets actually flashing the target) so I build on a fast 
desktop and test on the target, seamlessly. I don't see the problem and 
your comments about "bloat" seem to be something from personal view of 
development ;)

Amongst other things, I do the production builds for WSJT-X and I would 
like a set up where I can make an ARMv7 package without having the 
target on the bench here.

Whoa! Where did tablets come from?

Qt has excellent support for Andriod and iOS but I would agree that we 
would need to do some work to support gesture driven keyboard-less 
systems like tablets and phones. You might want to contribute to such an 
effort if you have teh relevant Qt experience but currently I'm not 
aware of any need from users aside from off-hand comments from a few 
that queried if WSJT-X could run on a tablet.

My requirement is on behalf of users that have little or no development 
experience and want to use a SoC type boards like the 
PI2/BeagleBlack/fill in your preference of ARM based hardware in their 
shacks or portable stations with a keyboard mouse and perhaps a USB 
sound device. We have plenty of those and more would join since the cost 
of entry is so small. They just need something to install and go. Greg 
has enabled the armhf builds for Debian AFAIK and they may appear in the 
repos in time but for now a DEB or RPM package is a convenient stepping 
stone.

Yes, I've enabled the armhf builds on Launchpad for the GA release 
branch, v1.6.0 at present. I also tested builds with the v1.7.0 branch. 
At present, it's only available as a PPA.

As soon as we are free of the Hamlib3 local build requirement, I can 
push the package to Kamal for review then hopefully update the current 
repository version when the v1.7.0 GA Release happens.

Hi Paul,

several users have built WSJT-X for the Rasberry Pi2 successfully. AFAIK 
they have all built on the target machine, Ubuntu based distributions 
are probably the way to go as we know the required prerequisites are in 
the repos.

I am keen to hear from anyone who has a working hosted build system for 
cross compiling as this would seem to be a better way of supporting 
builds for SoC type targets like the Pi2. I would like to have a VM here 
set up for cross building for the Pi2 and other and other ARM CPU targets.

Hi Richard,

I know how to build a cross tools environment but the devil is always in 
the detail. I was hoping someone with a target board has built a 
suitable cross build environment on, say an Intel Linux machine, and can 
detail the necessary steps to get all the prerequisites built to 
complete a WSJT-X cross build.

Yes it should be OK , wsjtx and wspr will build and run, so does Hamlib
but wsjt10 is too heavy on resources for a Rasp Pi2'
Runs OK on a Odroid XU4, sorta super rasp Pi2;
Should you need high speed modes, until they are added here you can use MSHV, 
PM me for the
MSHV_ARMHF.pro file to build it.

At the moment Bill JTSDK builds as is on a ARMHF platform .
I'm happy to check on my system if something will build on a ARMHF platform.
I have a C1+ which is very very close to a Rasp pi2, both are ARMhf
