Description
I have built a 12bit libjpeg (from Frank's work at http://sourceforge.net/projects/libjpeg/) to coexist alongside the standard 8bit lib as 'libjpeg12'. This was for use by my libtiff build, and others that may want to use it.
It works fine in GDAL for TIFFs with 12bit jpeg compression. Then I noticed the GDAL configure --with-jpeg12 option so GDAL can support 12bit jpegs directly, and 12bit jpeg in NITF, but it only compiles with the internal jpeg12.
Maybe 100K of object code duplication is not worth the trouble...

Even, did r28268 "JPEG: avoid useless code duplication for 12-bit JPEG support" fix this issue?

Replying to jratike80:

No William's ticket is about being able to link an external libjpeg12. The current configure option --with-jpeg12 just instructs to build the internal libjpeg12. r28268 is just a small optimization to reduce a bit binary size by eleminating stuff unneeded for 12bit JPEGs

I guess this ticket is still valid. Otherwise also https://trac.osgeo.org/gdal/wiki/TIFF12BitJPEG needs refreshing.

This ticket has been automatically closed because Trac is no longer used for GDAL bug tracking, since the project has migrated to GitHub. If you believe this ticket is still valid, you may file it to https://github.com/OSGeo/gdal/issues if it is not already reported there.
What might be the status of this ticket? Still the same after 5 years?
