Mmm, since you seem to know a lot about this rpath issue, maybe you could
answer my questions on this :
I package ocaml (Objective caml is a ML dialect, and the package contains
the compiler suite for it), and it recently started supporting shared
libraries for the stubs needed to bind C libraries into bytecode ocaml
executables run in a virtual machien (ocamlrun).
All such shared stub libraries are reported by lintian as having a rpath, but,
from my understanding of it (after having read your mail), this is ok, since
most probably the rpath is related to the way the virtual machine finds and
links these stub libraries with its own ld.so like functionality, and not
anything related to gcc or ld.so ?
If this analysis is correct, i suppose i can simply ignore those lintian
errors, or provide lintian overrides for them.
How can i check what is contained in the rpath of a shared library to make
sure it is ok to override this lintian error ?
