[gdal-dev] "symbol(s) not found for architecture x86_64" when compiling GDAL 2.1.0 on Mac OS X

[Lucian Plesea]

MRF depends on JPEG, PNG, zlib and TIFF.  Since those are always available as GDAL internal, it doesn’t makes sense to change the code to make it work without some of them.  It would only create seldom used configurations that would have to be tested and maintained.
Turning MRF off if any of the dependencies are missing would be safer and simpler.

Michal,

You need to disable the MRF driver as well since it needs libpng and libjpeg. Unfortunetely I just discovered that the intended --without-mrf option didn't work because of a typo. I fixed this by a simple patch in https://urldefense.proofpoint.com/v2/url?u=https-3A__trac.osgeo.org_gdal_ticket_6811&d=DwIGaQ&c=n6-cguzQvX_tUIrZOS_4Og&r=0orhATy81rhG89NwPqBqSPUWjOvyYU8QxFh5_mt-XF8&m=zspmUIO7S_ZVn-9UgO9SW5klMbpNfrJggIKRaHNbkZQ&s=CkAIea7yNc6i_N2r7C8oLBtDRo9vSrZf5jRj712nkwE&e=  that you can apply.



Lucian,

wouldn't it make sense to either be able to build MRF without PNG and/or JPEG support, or if that doesn't make sense automatically disable MRF when they are not available ?
