The following link provides some useful historical insight: http://ecos.sourceware.org/ml/ecos-patches/2005-06/msg00060.html CYGPKG_LOADER provides a dynamic library loader (loading of .so files). This is experimental code and has not been touched for many years. Ref: http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/ecos/packages/services/loader/current/docs/notes.txt?rev=1&content-type=text/plain&cvsroot=ecos CYGPKG_OBJLOADER provides an object file loader (loading of .o files). This is more recent code that is in current use and should be functional on the target architectures for which a relocator has been implemented (ARM, i386, PowerPC). Ref: http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/ecos/packages/services/objloader/current/doc/notes.txt?rev=1&content-type=text/plain&cvsroot=ecos I hope this helps.
