Why does the Polyspace Report Generator terminate with an error?

I am unable to correctly launch Polyspace Report Generator. I gets a pop-up message 'Report generation terminated with error' when I launch the Report Generator to run report in the Viewer (Results Manager) of Polyspace (Reports >Run Report).

Message is something like that:

Template : ...\templates\CodingRules.rpt

Results-dir : C:\...\results

Format : PDF

Output-Name : C:\...\Polyspace-Doc\<name>_CodingRules.pdf

Noview : enabled

Why is this happening?

This may be due to the java memory used to generate the report. It happens mostly with PDF format. It might be helpful to

• Try to generate report with another format like HTML or Word (it is then possible to save the document in the pdf format)
• Try to increase the jvm memory available to generate reports:

1. Close the Polyspace User Interface
2. Open Java.opts file

Until R2012b

Increase the java memory size by editing ..\Polyspace_Common\ReportGenerator\ReportGenerator\bin\x86-mingw32\java.opts

By default it contains 512 -Xmx512m. Try -Xmx1024m

I would not recommend trying much higher if the machine only has 2 GB of memory installed.

Since R2013a

Increase the java memory size by editing ...\MATLAB\<version>\polyspace\bin\win64\java.opts

The amount of memory to allocate to the Java VM depends on the memory available on the machine where the report is generated.

If the machine has 16Gb of RAM, you can try with 8Gb. In this case the contents of java.opts will be : -Xmx8192m (8192Mb, i.e. 8Gb)

1. Save and close the java.opts file
2. Re-open Polyspace UI and try generating again a report.
