gdalUtils and gdal 3.0.2 : ERROR 1: PROJ: proj_create_from_wkt: Cannot find proj.db

[mgageo]

Hello, I use gdaUtils with the gdal version from QGIS : https://www.qgis.org/fr/site/forusers/download.html https://qgis.org/downloads/QGIS-OSGeo4W-3.10.0-2-Setup-x86_64.exe

On a command like

ogr2ogr('rgdal.geojson','rgdal.json',t_srs="EPSG:2154",verbose=TRUE) Checking gdal_installation... Scanning for GDAL installations... Checking the gdalUtils_gdalPath option... GDAL version 3.0.2 GDAL command being used: "C:\Program Files\QGIS 3.10\bin\ogr2ogr.exe" -t_srs "EPSG:2154" "rgdal.json" "rgdal.geojson" [1] "ERROR 1: PROJ: proj_create_from_wkt: Cannot find proj.db" "ERROR 1: PROJ: proj_create_from_wkt: Cannot find proj.db"
[3] "ERROR 1: PROJ: proj_create_from_database: Cannot find proj.db" "ERROR 1: Failed to process SRS definition: EPSG:2154"

I have an other version of gdal from http://download.gisinternals.com/sdk/downloads/release-1911-x64-gdal-3-0-mapserver-7-4.zip in the directory d:\gdal30

I replace the system call "system(cmde, intern = TRUE)" by a small script, cf https://framagit.org/mgageo/osmdata/blob/master/scripts/ogr2ogr.R and it's good
