Can't locate Getopt/Long.pm when generating a Qsys Project

[PGötz]

Quartus 19.1 has issues with its perl distribution on Linux. When generating a Qsys project, I get the following error:

```

Can't locate Getopt/Long.pm in @INC (you may need to install the Getopt::Long module) (

  @INC contains:

     /opt/altera/19.1/quartus/sopc_builder/bin/europa

```

It seems like the perl distribution points to the wrong directory because the library is located at `/opt/altera/19.1/quartus/linux64/perl/lib/5.28.1/Getopt/Long.pm`

I've found a bunch references in the perl distribution pointing to the wrong directory ( https://pastebin.com/wfUKcSjq )

A "fix" seems to be to link to the system perl executeable: http://www.armadeus.org/wiki/index.php?title=Quartus_installation_on_Linux#Perl_Getopt::Long

Hi,

I found a forum case that has a similar issue with yours. Perhaps the solution could help in your current case.

Thanks, I haven't found this thread :)

Hi Paul,

Do you able to solve the issue?

[PGötz]

I'm able to use Quartus by using the "fix" I mentioned above. Perl in the Quartus installation is still not working out of the box and requires manual changes

[SSchu40]

For me inserting the line

export PERL5LIB=/opt/intel_fpga/quartus/linux64/perl/lib/5.28.1

into

~/.bashrc

solved the problem. Please note that the application must be restarted to inherit the environment variable.

[PGötz]

Yeah, but this wasn't necessary with previous versions of Quartus and it could cause further problems or compatibility issues with my systems perl installation.

I have already another "fix" in use (as mentioned above), but would prefer if Intel would recognize this bug and fix it in the next build/release

[RichardTanSY_Intel]

Fyi, this bug will fix in future releases. In the meanwhile, please use the "fix" that you mentioned above.
