[Gdal-dev] solaris run-time linkage

[Ian MacColl]

Hello:

Is there a way to compile and link gdal and ogr under solaris to 
specify search directories for the runtime linker?

I'm compiling mapserv for CGI. I don't control the CGI host so I can't 
define LD_LIBRARY_PATH. I can compile and link on an identical solaris 
2.8 host using gcc 2.95. Libraries gdal depends on seem to assimilate 
LDFLAGS from the environment, with a -R option to pass runtime search 
directories. However, gdal uses c++ rather than ld for linkage, and 
it's not immediately obvious how to pass the search list through to the 
linker (I've tried both -R... and -Wl,-R... in both LD_SHARED and LIBS 
in GDALmake.opt). It looks as though the configure scripts sees the 
LDFLAGS value, and puts it in config.status, but it doesn't end up in 
the gdal make files.

The error that I'm getting, for example when I run ogr2ogr, is failure 
to find libproj. I think this means ogr2ogr is finding libgdal, but 
libgdal can't find libproj. Setting LD_LIBRARY_PATH makes the error 
disappear.

So, is there a way to specify the search directories in libgdal and 
friends?

If not, I guess I'm stuck with either the default search directories, 
or trying to wrap mapserv in a script that sets LD_LIBRARY_PATH. Any 
other ideas?

thanks

Ian
