Not correct - this switch tells the linker to look in the directoryt
named /rstc/user1/erc/pushkar/ossim/src/packages/gdal/.libs/libgdal.a
for a library files. Of course, there is no such directory.
If the libraries are indeed in
/rstc/user1/erc/pushkar/ossim/src/packages/gdal, then the above link
line looks correct. Perhaps the permissions are incorrect.
To ensure satatic library is used, check your compiler/linker options.
There should be something like "-static" or "-static_shared" available.
