When trying to build a JPEG plugin using ProjectBuilder for Mac OS X,
everything builds, but when linking the bundle I get the error that the
following symbols are undefined:
_error_exit
_jpeg_mem_dest
_jpeg_mem_src
_jpeg_mem_src_newLocationOfData
Interestingly, none of these symbols exist anywhere in the source code I
got from jpegsrc.v6b.tar.gz. They are only used in the generated plugin.
When I look at
JPEGReadWriter2Plugin>>primJPEGReadHeader:fromByteArray:errorMgr:
I see that these are being emiited directly into the C code.
Has anyone else gotten this to work? Did I leave out a step in plugin
generation?
