Problem with the initialisation of a grass session in R #88

Downgrading rgrass to version 0.3-9 did not solve the issue. |

@amelinevallet Could you run |

@rsbivand here is what I obtain with rgrass_0.4-2 I thought I managed to downgrade rgrass to version 0.3-9 in my previous message, but indeed, not : when I uninstall the package and force the installation of version 0.3-9, version 0.4-2 is automatically installed (see bellow). I have to figure out how I can install correctly this previous version before being able to make the required test with version 0.3-9. Sorry for that. |

Get 0.3-9 from https://cran.r-project.org/src/contrib/Archive/rgrass/rgrass_0.3-9.tar.gz and use: |

I have managed to install rgrass 0.3-9, here is session and traceback info: |

Please install from the source package downloaded from CRAN only, do not use The underlying problem may be that GRASS 8.3.2 is emitting XML that is not in UTF-8 encoding in your locale. R sees your locale as |

Yes, indeed session_info() indicates a mismatch between loaded and on-disk rgrass 0.3-9 versions when I installed it with devtools. I re-installed rgrass 0.3-9 version from the source package as indicated. Here is the session_info and traceback info: |
|
Regarding your suggestion about encoding, I checked GRASS and R sessions locales. Here is what I obtained for GRASS And here for R: So if I understand properly, both use the same encoding (fr_FR.UTF-8)? Is there something else to check for GRASS? @rsbivand do you know where the xml files generated by GRASS are located ? I could check if their encoding really is fr_FR.UTF-8, or if there is an incomplete string somewhere ? |

I removed GRASS 8.2 version, but I am re-installing it right now. |

To install GRASS 8.2, and easily switch between GRASS versions, I used the following lines: |

With GRASS 8.2 I do not receive the same error message: I am not sure to understand what is the problem, but apparently, with the downgraded GRASS 8.2 version and rgrass 0.3-9, the error do not appear anymore. So we do have a workaround until the issue with GRASS 8.3 is more clearly identified, it is a good news !!! Thanks, |

Could you please try with rgrass 0.4-2? |

I just tried, it worked with rgrass 0.4-2 too. Here is the session_info for the test with rgrass 0.3-9 And here for the test with rgrass 0.4-2 I hope this information is useful |

A pbm raised when using GRASS 8.2 : it is not possible to download addons from github with g.extension. The problem is documented here: https://gis.stackexchange.com/questions/474069/cannot-install-grass-addons-in-grass-8-2-ubuntu-jammy, and the workaround proposition works well. |

Having at last rebuilt my GRASS 8.3.2 (GEOS was updated last night, so I rebuilt GEOS, GDAL and finally GRASS from source) on Fedora 40, with R 4.4.0 and current rgrass, I do not see any problem. I cannot see from https://github.com/OSGeo/grass/commits/main/lib/gis/parser_interface.c that My guess might then be that GRASS 8.3.2 was not updated successfully from 8.2 in your case. How was GRASS 8.3.2 installed, from source or binary? If from source, which configure arguments were used, and did |

No problem here with GRASS GIS 8.3.2 and 8.5.0dev on Ubuntu 22.04 and R 4.4.0 + rgrass 0.4.2. |

Dear all,
Since I updated GRASS (8.2 -> 8.3.2) and rgrass (?-> 0.4-2), the installation seems broken and I can't start a GRASS session from R anymore. The error message I receive is the following:
Here below an example which I hope is reproducible:
I receive the same error message whether I use a custom path for temp files or not, and when I manually indicate within the initGRASS function custom entry parameters.
We are using GRASS 8.3.2 and R version 4.4.0 in a linux environment (Ubuntu 22.04.4 LTS). GRASS works well (I can use all applications from a GRASS session started in the terminal).
The environment variables seem all correct:
Anyone knows what might be the problem?
Best regards,
Améline
