Hi there,
First off, you'd better be asking this kinda stuff on the apropriate
mailinglist.
Concerning the gcc part: obviously you lack a -l<libname> statement,
because you have undefined symbols (I assume -lgdal or -l GDAL). If the
lib is not in the search path, you'll need to add an -L statement aswell.
Your 'Makefile.in' is autogenerated - obviously via automake. So, the
place to start, is the Makefile.am to fix things, or, if you are using
autoconf aswell, your configure.in (or configure.ac). The right place to
ask such things would be an autotools mailinglist.

Hi,
I'm trying to compile a program called StarSpan using gcc on my Mac OS X
machine. StarSpan depends on a library called GDAL. When I first tried
to configure/make StarSpan, it complained about not being able to find
gdal.h. So, I found gdal.h on my system, and added a -I entry to
Makefile.in. Now, make gets a lot further. Currently, I'm getting:
Undefined symbols:
"GDALDataset::RasterIO(GDALRWFlag, int, int, int, int, void*, int, int,
GDALDataType, int, int*, int, int, int)", referenced from:
RasterizeObserver::addPixel(TraversalEvent&) in
starspan_rasterize.o
...
(many more lines)
I have found the .cpp file (gdaldataset.cpp) that contains
GDALDataset::RasterIO, which is part of the GDAL source distribution.
But, I'm not sure where the binary containing this symbol resides. I'm
also not sure where/how to add a -L entry in Makefile.in once I find the
needed library.
Any suggestions greatly appreciated!
