We're trying to migrate our windows based build from 6.3 to 6.4.0 and
I'm having trouble with the linker. We have been building our system
using shared objects that depend on other shared objects. Everything
worked fine until we started using the 6.4.0 linker. We're getting
unresolved symbols with the suggestion to use -rpath-link option. I
tried this option, without success, but it didn't seem like the right
solution because the missing file is called out with its full pathname.
The results from the build, and the directory contents for the missing
file, are included below. Any ideas? I suspect I could include the
missing library explicitly in the linker command line but that is hardly
an ideal solution; we have many, many programs which we build and
besides, isn't that the point of having shared objects that depend on
other shared objects? Thanks.
