can't build pulseview (Slackware current)

rwcooper · 01-02-2021, 10:07 AM

Hi, I upgraded to Slackware current on 2021/01/01 and I can't build pulseview. I have built and installed all of its prerequisites that needed building. I did not rebuild qt5. I am using sbopkg and the latest version of Ponce's repository. I have included the last few lines of output from the build hoping this will help. Any help/suggestions is greatly appreciated. Thank you.

Code:

/usr/include/qt5/QtCore/qdebug.h:420:15: note:   template argument deduction/substitution failed:

Can you please stop creating new topics for your build failures? All three of them are related, best to keep the discussion in one single thread.

pulseview, beside a version bump to 0.4.2, on current also needs a patch for qt-5.15.x, like this

http://cgit.ponce.cc/slackbuilds/commit/?h=pulseview

P.S. Alien Bob is right: if you had tell from the start that you aimed to build pulseview I won't have to do this thing one step at a time...

rwcooper · 01-02-2021, 10:59 AM

OK, sorry about that.

Man, you bombed this forum with threads about ... what does that thing after all?

Its a front end, with a graphic display, to a logic analyzer. I use the logic analyzer to view signals from circuits I design for embedded systems. This is just a hobby for me. I won't commit to upgrading my main computer until I have pulseview working on my test system.

I'm totally lost now. I followed the link given above and I'm OK with the changes to .Slackbuild and .info. I'm assuming the patch command is part of the changes to .Slackbuild. After that I don't know what to do! Where are the other files referenced in the other diff commands? Once I change the other files what do I do with them? I seem to be down to the last step in building pulseview bit don't know how to proceed. Thanks for any help you can give me.

If you use sbopkg, the tree is located here : /var/lib/sbopkg/

Thanks. I already know that, but several of the files mentioned by following the link are NOT in that tree. Any other suggestions?

ponce · 01-02-2021, 02:55 PM

the modifications that you can find in every branch of the git tree I linked you are based on the scripts you can find on SBo, let's take for example the one dedicated to pulseview

http://cgit.ponce.cc/slackbuilds/commit/?h=pulseview

as you can see, under the "author" and "committer" lines, there's another "commit" line that ends with a "patch" link: that links to a patch that you can apply to the pulseview script on SBo.

so you can:

- download the tarball of the pulseview build script from SBo and extract it

Code:

wget -O - https://slackbuilds.org/slackbuilds/14.2/academic/pulseview.tar.gz | tar xz

- go in the resulting directory

Code:

cd pulseview

- download the linked patch and apply it to the pulseview stuff

Code:

wget -O - "http://cgit.ponce.cc/slackbuilds/patch/?id=e3aab68532be77fe27a531196c6a34171ccc42c3" | patch -p3

- after that you can dowload the sources and build pulseview

Code:

. pulseview.info
wget $DOWNLOAD
./pulseview.SlackBuild

if you have to build something manually you can do the same thing for every branch listed here (obviously with the relative references changed)

Ponce, thanks so very much for your patience and help! Pulseview built following your excellent and detailed instructions...Randy

rwcooper · 01-02-2021, 03:55 PM

I was a bit premature. pulseview starts and runs but I get an error message: "module sigrokdecode not loaded". I don't get that message on my main computer. I built and installed libsigrokdecode. Any any suggestions for what may be causing this are greatly appreciated.

ponce · 01-03-2021, 01:36 AM

maybe I got why this happens: pulseview needs to be bumped too to a git snapshot.

try the same procedure I described above but with a different patch.

rwcooper · 01-03-2021, 09:11 AM

Ponce, exactly the same thing happened. I get the following when I run pulseview.

Code:

sudo pulseview
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Setting "View_AllowVerticalDragging" changed to QVariant(bool, true)
srd: sigrokdecode module not loaded.
srd: Failed to load decoder gpib: sigrokdecode(3) not loaded
srd: AttributeError: Failed to load decoder iec: no 'Decoder' attribute in imported module: module 'iec' has no attribute 'Decoder'

Additional info:

Code:

ls /var/lib/pkgtools/packages/ | grep pulseview
pulseview-20210103_d023660-x86_64-1_SBo

ls -l /usr/lib64/libsigrokdecode*
-rwxr-xr-x 1 root root   987 Jan  2 12:43 /usr/lib64/libsigrokdecode.la*
lrwxrwxrwx 1 root root    24 Jan  2 12:48 /usr/lib64/libsigrokdecode.so -> libsigrokdecode.so.4.0.0*
lrwxrwxrwx 1 root root    24 Jan  2 12:48 /usr/lib64/libsigrokdecode.so.4 -> libsigrokdecode.so.4.0.0*
-rwxr-xr-x 1 root root 77248 Jan  2 12:43 /usr/lib64/libsigrokdecode.so.4.0.0*

Pulseview runs and it recognizes and shows the correct number of channels for my logic analyzer.

Any help/suggestions for solving this are greatly appreciated. Thank you.
