Preview in 6.070 GUI issues

[timmbo9]

Os Ubuntu 24.04
With chordpro file loaded pressing preview opens firefox but firefox complains it cannot find the file
/tmp/filename. It even displays the filename in error message. If I go to tmp the file is there and able to be
opened and read in a pdf viewer.

If I remove firefox from the system then preview opens in default pdf viewer program.

I would think that chordpro would check the environment and use the default browser. In my case BROWSER=vivaldi.
That is an environment variable set for use in abc2svg.

In Settings > Preview, please uncheck [x]PDF Viewer

ChordPro should now use its built-in PDF viewer.

[timmbo9]

I'm using dev 6.070 and don't see this. No Settings > Preview.

[sciurius]

(The smell increases. Not that it matters for this case, but can you upgrade to the release version?)

Try this:

• start wxchordpro
• click create new song
• click messages

It should say something similar to

07:45:33: Using styled text editor
07:45:33: Using embedded PDF viewer
07:45:33: New song: New Song

[timmbo9]

it says Using external PDF viewer.
Which github branch should I be using ? currently on dev but I did try R6.070_maint since it had more recent activity.

This is what I was afraid of... I fear that Ubuntu does not provide a complete wxWidgets build.

Can you find out what wxWidgets packages are installed, and what wx libraries there are in lib?

[timmbo9]

ldconfig -p -v |grep wx > wxliblist.txt
wxliblist.txt

installed wx packages

And list of available ubuntu wx apts:
aptlist.txt

[sciurius]

Can you add libwxgtk-webview3.2, does it make a difference?

[timmbo9]

Added. reinstalled chordpro; no difference.

Does wx-config --libs all now report a.o. the webview libraries? You may need to install the dev version of the wx libraries as well.

If so, can you, try to rebuild libwx-perl from source?
Alternatively, you can try to build this enhanced version instead.

[sciurius]

I've set up an Unbuntu 24.04.1 LTS and I can reproduce the problem. I'll see what I can do.

[sciurius]

Okay, the problem: Ubuntu 24.04.1 LTS ships with wxWidgets but does not install the WebView component. As a result, the system provided Alien::wxWidgets and wxPerl do not have DocView.

I think this will work:

• # apt-get install libwxgtk-webview3.2-dev
• # apt-get remove libalien-wxwidgets-perl
• make sure that /usr/lib/x86_64-linux-gnu/perl5/5.38/Alien/wxWidgets/Config/gtk_3_2_4_uni_gcc_3_4.pm is no longer there (remove explicitly if needed).
• # apt-get install cpanminus
• # cpanm Alien::wxWidgets

Download Wx-3.004.tar.gz from https://github.com/sciurius/wxPerl/releases/tag/R3.004

• $ tar xvf Wx-3.004.tar.gz
• $ cd Wx-3.004
• $ perl Makefile.PL
• $ make
• $ sudo make install

Now wxChordPro should be fully functional (using the embedded PDF viewer).

[sciurius]

This may be easier:

• # apt-get install libwxgtk-webview3.2-dev
• # cd /usr/lib/x86_64-linux-gnu/perl5/5.38/Alien/wxWidgets
• # patch -N < alien-wxwidgets-webview.patch.txt

Now proceed with downloading, building and installing Wx-3.004.tar.gz.

alien-wxwidgets-webview.patch.txt

[sciurius]

And this may be best:

• # apt-get install libwxgtk-webview3.2-dev
• # apt-get remove libalien-wxwidgets-perl
• # apt-get purge libalien-wxwidgets-perl
• # apt-get install cpanminus (if you don't have cpanm installed already)
• # cpanm Alien::wxWidgets
• # cpanm --notest https://github.com/chordpro/chordpro/releases/download/R6.070/Wx-3.004.tar.gz
• # cpanm https://github.com/chordpro/chordpro/releases/download/R6.070/App-Music-ChordPro-6.070.tar.gz

I had an issue that seems related to this. I am on Pop OS 22.04 LTS.

If I tried to run chordpro with libalien packages installed through apt it would run, but it would open pdfs in firefox (even though my default browser is brave). So I followed the instructions on chordpro's website. I installed Alien::wxWidgets with no issues. Then, installing Wx from this repository failed. When digging through the build.log I found that it failed some tests because it couldn't find Wx::Media. So I tried installing Wx::Media, but this failed right away and in build.log was an error: No such 'link' library: 'adv'.

What finally fixed the issue was running the sudo cpanm https://github.com/chordpro/chordpro/releases/download/R6.070/Wx-3.005.tar.gz WITH --notest flag. Originally I forced the installation with --force after which it installed, but running 'wxchordpro' would fail with Wx::Media was not found. After uninstalling Wx and reinstalling with --notest it for some reason works as expected. I have no idea why that fixed it, but I thought it is worth sharing.

I will test this again on a different machine to make sure that this is reproducable. I will let you know how that went in a few days.

[sciurius]

Thanks for the headsup. Do you have information on what wx packages and libraries are installed on Pop OS when you install libwx-perl ?

[om1cmd]

Here are outputs of running apt install libwx-perl and also apt install libalien-wxwidgets-perl. Neither of those was installed by default. I only tried installing to see what would happen as part of troubleshooting.
packages.txt

[sciurius]

Perfect. So installing libwx-perl adds libalien-wxwidgets-perl (as it should) and the required wx libraries except for webview.

So I tried installing Wx::Media, but this failed right away and in build.log was an error: No such 'link' library: 'adv'

Wx::Media is provided by Wx, and the default version of Wx gives this (and some other) errors when building against wxWidgets later than 3.0.

I installed chordpro today on another system with Pop OS 22.04 LTS. I ran into all the same issues as the first time. Installing Wx-3.005 with --notest makes sure it gets installed, but does not resolve the underlying problem. So I made sure I had all the libwxgtk3.2 packages*. That includes libwxgtk-media3.2-1 libwxgtk-media3.2-dev libwxgtk-webview3.2-1 libwxgtk-webview3.2-dev libwxgtk3.2-1 libwxgtk3.2-dev. I am not sure if all of these are actually required. I also removed all libwxgtk3.0 packages. Then I followed these instructions.

• # apt-get remove libalien-wxwidgets-perl
• make sure that /usr/lib/x86_64-linux-gnu/perl5/5.38/Alien/wxWidgets/Config/gtk_3_2_4_uni_gcc_3_4.pm is no longer there (remove explicitly if needed).
• # apt-get install cpanminus
• # cpanm Alien::wxWidgets

For Pop OS the file gtk_3_2_1_uni_gcc_3_4.pm is in /usr/local/lib/x86_64-linux-gnu/perl/5.34.0/Alien/wxWidgets/Config.

That got Chordpro installed and running with build in pdf viewer on Pop OS.

*As of now, these are not available in default repositories, but I got them from Kicad repos.
