Can't run appImage on Ubuntu 16.04.2 LTS without Try::Tiny module

[burbilog]

Version

Slic3r 1.33.5 Prusa

Operating system type + version

Ubuntu 16.04.2 LTS

Behavior

Download Slic3r-1.33.5-prusa3d-linux64-full-201702171509.AppImage and try to run

Expected result: running Slic3r

Actual result: Slic3r fails with following message:

cpanm install Try::Tiny fixes the problem, but hey, it's appImage, eh?

STL/Config (.ZIP) where problem occurs

Config does not matter I suppose...

[bubnikv]

It looks like there is another problem going on: The appimage shall not pull the system perl modules. I think what you are seeing is, the system perl modules are pulled before the ones from the AppImage, and seemingly your Perl modules have different dependencies.

[bubnikv]

Looking inside the AppRun script generated by the AppImage suite, it starts an application defined in Slic3r.desktop. It looks like the AppRun is flawed, as it first sets up the paths to point inside the AppImage, but then it starts the system installed Slic3r script.

I am not sure where shall I fix it. @probonopd any idea?

[probonopd]

On Ubuntu 16.04 without a system-installed Slic3r, the AppImage launches with the following output on the console:

me@host:~$ /home/me/Downloads/Slic3r-1.33.5-prusa3d-linux64-full-201702171509.AppImage 
Use of uninitialized value in subroutine entry at /tmp/.mount_isAMZR/usr/bin/lib/site_perl/5.22.0/Slic3r/GUI/Plater.pm line 170.

Which shows that at least in principle, AppRun does launch the correct (bundled) Slic3r.

So I suspect as soon as there is also a Slic3r installed in the system, it somehow picks up the system one/mixes up the two. More investigation needed.

[bubnikv]

@probonopd

Thanks. The issue is in how the AppRun pulls the name of the executable from the *.desktop file.
It simply gets the file name and it starts it, without prefixing it with the "local" path.

[probonopd]

I do not get the "Use of uninitialized value in subroutine entry" with the AppImage I had generated earlier, https://bintray.com/probono/AppImages/download_file?file_path=Slic3r-1.31.6.prusa3d.glibc2.14-x86_64.AppImage. Can you confirm that the issue reported in this ticket is also present in that version?

[probonopd]

Thanks. The issue is in how the AppRun pulls the name of the executable from the *.desktop file.
It simply gets the file name and it starts it, without prefixing it with the "local" path.

AppRun exports $PATH to include usr/bin in the AppImage.

If you look at the AppImage, it has Exec=slic3r.wrapper --gui in the desktop file, which launches the shell script usr/bin/slic3r.wrapper inside the AppImage because it is on the $PATH.

[probonopd]

@bubnikv is the script that you are using to produce the AppImage available on GitHub?

[bubnikv]

@probonopd

AppRun exports $PATH to include usr/bin in the AppImage.
If you look at the AppImage, it has Exec=slic3r.wrapper --gui in the desktop file, which launches usr/bin/slic3r.wrapper inside the AppImage.

You are right.

What does the
HERE="$(dirname "$(readlink -f "${0}")")")
do?
Namely, why is readling -f necessary? What is special about ${0}, that readlink -f is needed?

slic3r is a bash script, containing the following three lines:
DIR=$(dirname $0)
export LD_LIBRARY_PATH="$DIR/bin"
exec "$DIR/bin/perl5.22.0" "$DIR/bin/slic3r.pl" "$@"

I think the problem lies in my slic3r script. I wonder, whether I shall modify the script to call readlink -f on $0 as well?

@burbilog @probonopd I think the AppImage generates some debug info if started with DEBUG=1. @burbilog would you please provide that log? Thanks.

[bubnikv]

@probonopd is the script that you are using to produce the AppImage available on GitHub?

It is part of our build suite to build and pack on all platforms. The build suite is currently private. But I am not doing anything special, I just slightly modified the scripts you have provided.

[probonopd]

Here are my logs of mine and yours:

Slic3r-1.31.6.prusa3d.glibc2.14-x86_64.AppImage.log.txt
Slic3r-1.33.5-prusa3d-linux64-full-201702171509.AppImage.log.txt

[probonopd]

Ah, export LD_LIBRARY_PATH="$DIR/bin" in usr/bin/slic3r throws away the LD_LIBRARY_PATH that AppRun has set before. I guess it should be export LD_LIBRARY_PATH="$DIR/bin":$LD_LIBRARY_PATH?

[probonopd]

I think the key lies in

@inc contains: /tmp/.mount_93wzoj/usr/bin/bin/lib /home/rm/perl5/lib/perl5 /tmp/.mount_93wzoj/usr/bin/lib/site_perl/5.22.0/x86_64-linux-thread-multi /tmp/.mount_93wzoj/usr/bin/lib/site_perl/5.22.0 /tmp/.mount_93wzoj/usr/bin/lib/5.22.0/x86_64-linux-thread-multi /tmp/.mount_93wzoj/usr/bin/lib/5.22.0

So why is it loading stuff from /home/rm/perl5/lib/perl5/ then? (I am not a Perl expert...)

[bubnikv]

@burbilog I think the problem seems to become evident. Greping perl from your log shows:

It looks like we (either me or probably @probonopd) need to filter out the PERL environment variables before running a perl script packed into an AppImage. Maybe AppImage should initialize the shell environment from scratch? I am far from being a Linux expert, so I don't know how to do that as of now. I will look into what PERL environment variables are used to put together the @inc paths and what are their priorities.

[bubnikv]

@burbilog would you please try to undefine PERL5LIB before running the AppImage?

[bubnikv]

Reading
http://stackoverflow.com/questions/2526804/how-is-perls-inc-constructed-aka-what-are-all-the-ways-of-affecting-where-pe

I need to unset PERL5LIB and PERLLIB in the slic3r shell wraper. I will try to update the Linux and OSX builds as both may potentially affected. Also the Windows slic3r.exe wrapper shall filter out the two variables.

[burbilog]

@bubnikv yes, removing PERL5LIB from environment fixes the problem.

@burbilog Great, I am running another build with
export PERL5LIB=
export PERLLIB=
at the start of the slic3r shell script. Hope this will fix it.

This is what I am currently doing in AppRun.c.

Its intention is to add the inside of the AppImage to the Perl search path, similar to what I do with $PATH.

Should I change it?

[bubnikv]

@probonopd I think it depends. I suppose Slic3r is the first AppImage packing its own Perl interpreter. If the AppImage uses the system-wide perl interpreter, then your implementation is all right.

I think it would be sufficient to keep it as it is, but to document it well, so if someone is packing a Perl interpreter into the AppImage, he would know he needs to unset PERL5LIB and PERLLIB in his startup script.

[probonopd]

I think bundling the Perl interpreter is the right thing to do.

[bubnikv]

@burbilog I have updated the Linux & OSX binary builds to unset PERLLIB & PERL5LIB. Please download the updated AppImage from
https://github.com/prusa3d/Slic3r/releases/tag/version_1.33.5
and give it a try, so we can close this issue :-)

[probonopd]

Don't know if this is serious, but I am still getting

me@host:~/LibrePCB/build$ /home/me/Downloads/Slic3r-1.33.5-prusa3d-linux64-full-201702181304.AppImage 
Use of uninitialized value in subroutine entry at /tmp/.mount_BchhWk/usr/bin/lib/site_perl/5.22.0/Slic3r/GUI/Plater.pm line 170.

[bubnikv]

@probonopd I don't know what is the Perl complaining about. The line initializes a menu, and with success.
$self->{htoolbar}->AddTool(TB_LAYER_EDITING, 'Layer Editing', Wx::Bitmap->new($Slic3r::var->("variable_layer_height.png"), wxBITMAP_TYPE_PNG), wxNullBitmap, 1, undef, 'Layer Editing');

It must be something inside the wxWidgets perl binding. Not nice, but seems to be harmless. Something for the next release I suppose.

[burbilog]

@bubnikv Yes, it works now.

[bubnikv]

Thanks to all involved, happily closing :-)
