[osg-users] [build] TIFF plugin fails when TIFF is compiled with JPEG compression support

[Bob Smith]

Hi,

I compiled the TIFF library with JPEG compression support. When I now build OpenSceneGraph, the plugin tiff fails because it has linker errors and cannot find JPEG library... Is there a workaround?
The CMakeLists.txt for the TIFF plugin only links against TIFF library, not JPEG...

VS2012, OSG 3.1.1, but I guess it should apply to all version...

Thank you!

Cheers,
Bob

I suspect that OSG's TIFF plugin never expected to support JPEG
compression or require the JPEG library to be linked. I'd think that
most folks will use a .jpg file if they want JPEG compression (is there
an advantage to using a TIFF container for JPEG data?)

If you want this feature for TIFF files, you'll probably have to edit
the CMake files to link in libjpeg when compiling the tiff plugin.
