Error While Executing buildHelicsInterface.m #2

Closed StormsHalted closed 2 years ago

StormsHalted commented 2 years ago

Afternoon,

I get this error when running the buildHelicsInterface.m script:

buildHelicsInterface

Error using matlab.io.internal.archive.core.builtin.extractArchive Invalid TAR file /home/ali/Downloads/matHELICS-main/helicsTar.tar.gz.

Error in untar (line 84) files = matlab.io.internal.archive.core.builtin.extractArchive(tarFilename, outputDir, 'tgz');

Error in buildHelicsInterface (line 32) untar('helicsTar.tar.gz');

This past Friday we were looking at an issue with the Matlab untar command on macOS not handling symlinks at all. Based on the error you got, I’d guess that symlinks are the reason it is saying the tar file is invalid (which explains why it works on Windows which doesn’t have symlink support), or it can’t handle compressed tar archives; either way it seems like Matlab’s built-in untar command is even more broken on Linux.

So how to resolve this?

Since you’re on HELICS 2, this part probably isn’t relevant.

The workaround is to download the helics tar file manually, and extract it from the command line using the usual tar -xf system command. Then modify the matlab build script to use that manually extracted directory instead.
