c - libtiff error: Old-style JPEG compression support is not configured -
while converting tiff bmp using libtiff on mac os x, got these errors:
scannerdata.tif: old-style jpeg compression support not configured. scannerdata.tif: sorry, requested compression method not configured. i using libtiff in mac os x.
my implementation of tiff bmp:

take @ source code of libtiff in "nmake.opt"
# # uncomment , edit following lines enable jpeg support. # #jpeg_support = 1 ...
!ifdef jpeg_support libs = $(libs) $(jpeg_lib) extraflags = -djpeg_support -dojpeg_support $(extraflags) !endif so, default jpeg support not enabled.
