For a long time, I avoided MrSID like the plague. After trying to do *anything* useful with it, I finally gave up; the requirement for old versions of gcc, non-working on 64bit, etc. really gave me a negative impression of the SDK for MrSID reading. This was especially painful when working with OpenAerialMap, since MrSID has a practical lock on the market from ortho imagery datasources. (There are exceptions to this, but they’re usually JPEG2000 data, which was even worse to work with with the tools that I use, in general.)
However, after a set of discussions yesterday, I sat down and had a bit of a discusion about it, and Frank said that MrSID building in GDAL had gotten much easier. I didn’t really believe him, but I had the DSDK handy for other reasons, and reading the build hints, it was supposed to be easy.
Thinking I was going to prove Frank wrong, I started building. I did ./configure –with-mrsid=~/Downloads/Geo_DSDK-220.127.116.117; confirmed MrSID ‘yes’ in the output, then make.
3 minutes later, I had a gdalinfo and gdal_translate built on my Mac with MrSID support.
My historical problems with MrSID are completely irrelevant: the effort in the new SDK to support more platforms has clearly worked, and I can say that building MrSID support even on the Mac is trivial. A big thumbs up to the LizardTech folks for their effort in this regard — and to people like Frank and Michael for egging me on into learning this about the DSDK in the first place.
