Thank you Fernando, Chris, and Even, I tried what Fernando suggested. The /usr/bin/gdalinfo and /bin/gdalinfo files have the same inode number and the same checksums, which suggests that they are, in fact, the same.
However, I noticed that when I enter /usr/bin/gdalinfo --version in the terminal, I get: GDAL 3.10.0dev-1250e96221-dirty, released 2024/08/29 (debug build) Same as if I use /bin/gdalinfo. Whereas, if I run gdalinfo from the QGIS Processing Toolbox, the log shows GDAL having a different version (3.8.4 instead of 3.10): QGIS version: 3.34.4-Prizren Qt version: 5.15.13 Python version: 3.12.2 GDAL version: 3.8.4 GEOS version: 3.12.1-CAPI-1.18.1 PROJ version: Rel. 9.4.0, March 1st, 2024 I followed Even's suggestion and ran $ ldd /bin/qgis.bin | grep gdal libgdal.so.34 => /lib/x86_64-linux-gnu/libgdal.so.34 (0x00007a0581a00000) But I'm not sure what to do with that information. So now I'm thoroughly confused. I tried running $ sudo find -name gdalinfo ./home/andrew/.local/share/Trash/files/apps.10/gdalinfo ./home/andrew/src/gdal/build/apps/gdalinfo ./usr/local/share/bash-completion/completions/gdalinfo ./usr/share/bash-completion/completions/gdalinfo ./usr/bin/gdalinfo I tried running these other versions of gdal, and still got version "GDAL 3.10.0dev-1250e96221-dirty", or got a Permission Denied message (even if I was running as root, which is also weird). Where is QGIS's version of gdalinfo hiding? On Mon, Sep 23, 2024 at 9:11 AM Fernando M.
