I'm trying to convert some MrSID files to GeoTiff format. They are mostly over 20GB each. It seems the best way to do this is to use
gdal_translate with the MrSID drivers. Unfortunately, I can't find anything past about 2013 describing how to install them on Ubuntu. All answers seem to lead back to this question: How to make gdal_translate support MrSID driver however the question is related to converting to MrSID (not FROM MrSID). There are several tutorials from a long time ago but most are 7+ years old and no longer work:
I've tried building GDAL from source but am having trouble getting it to recognize all required libraries:
I also have some concern with this as I don't want to break the package-installed version of GDAL on my system used by QGIS and several other programs.
There are several tutorials using QGIS, however I can't find any new than about 10 years old. I know people have to work with the MrSID format and anything newer involves the same installation of the driver in GDAL. Short of using Windows, is there any solution out for converting MrSID to other formats?
