Answer 1

[Andrew Kornilov]

Java doesn't matter in this case. Installation of additional dependencies helps:

locales \

libxt6 \

libasound2 \

libgtk-3-0 \

libnss3

[Stefan Janecek]

On my Fedora 33 system (I'm not the OP), package names are of course a bit different. I have installed:

• libXt (contains libXtst.so.6)
• gtk3 (contains libgtk-3.so.0)
• nss (contains libnss3.so)
• alsa-lib (contains libasound.so.2)

I'm not sure what the "locales" package contains on Ubuntu, though. With these libraries installed, Polyspace report generator produces the errors shown in my post from Jan 22.

[Alessio Moscatello]

I confirm that the above libraries fixed the issue in PS 2020a and PS 2020b report generator.

Thanks.

Alessio

Please contact MathWorks Technical Support for a more detailed analysis of the issue: https://www.mathworks.com/support/contact_us.html .

One possibility is that the Java version needs to be updated. You can update your Java version and then try running the polyspace-report-generator command again.

[Stefan Janecek]

I'm seeing exactly the same error:

• OS: Fedora 33
• Polyspace Versions: R2020b and R2020a
• Java versions: 8.0.275 and 11.0.9
• Reports: Bugfinder Report, Bugfinder Summary, PDF and HTML output

I have reinstalled both versions twice to exclude file corruption while downloading Polyspace, and I have tried both installations with JAVA_HOME set to Java 8.0.275 and 11.0.9. All combinations produce a similar error message as the one shown by OP above, for both the Bugfinder Report and the Bugfinder Summary (tried both PDF and HTML output for both reports).

[Qiong Lan]

I had same issue as when I created a Polyspace Server R2021b container image on ubuntu:focal-20200423 with the following libs installed:

RUN apt-get update && apt-get install -y \
    language-pack-en-base \
    locales \
    libxt6 \
    libx11-xcb1 \
    libxtst6 \
    libasound2 \
    libgtk-3-0 \
    libnss3 \
&& rm -rf /var/lib/apt/lists/*
