I am exactly seeing this for 'shogun-octave' and I ask for your advise how to fix things. octave2.9 contains a couple of .so files in /usr/lib/octave-2.9.17, when building extensions to octave (as with shogun-octave), the resulting 'sg.oct' file is linked to some of the .so files in that directory, which of course is not available in ld.so.conf or the like, so dpkg-shlibdeps fails to find the libraries, e.g. liboctinterp.so. Also according to objdump also only has SONAME liboctinterp.so. As octave handles loading extensions itself, --rpath or the like are not normally needed. But what is the intended way of fixing things with the newer dpkg-shlibdeps ? Adding --rpath ? $ dpkg-shlibdeps build-octave/sg.oct dpkg-shlibdeps: failure: couldn't find library liboctinterp.so (note: only packages with 'shlibs' files are looked into). $ LD_LIBRARY_PATH=/usr/lib/octave-2.9.17/ dpkg-shlibdeps -v build-octave/sg.oct Scanning build-octave/sg.oct (for Depends field) Library liboctinterp.so found in /usr/lib/octave-2.9.17/liboctinterp.so Library libcruft.so found in /usr/lib/octave-2.9.17/libcruft.so Library liboctave.so found in /usr/lib/octave-2.9.17/liboctave.so Library liblapack.so.3 found in /usr/lib/liblapack.so.3 Library libblas.so.3 found in /usr/lib/libblas.so.3 Library libstdc++.so.6 found in /usr/lib/libstdc++.so.6 Library libm.so.6 found in /lib/libm.so.6 Library libgcc_s.so.1 found in /lib/libgcc_s.so.1 Library libpthread.so.0 found in /lib/libpthread.so.0 Library libc.so.6 found in /lib/libc.so.6 Looking up shlibs dependency of libstdc++.so.6 provided by 'libstdc++6' Found libstdc++6 (>= 4.2.1) in /var/lib/dpkg/info/libstdc++6.shlibs Looking up shlibs dependency of libc.so.6 provided by 'libc6' Found libc6 (>= 2.6.1-1) in /var/lib/dpkg/info/libc6.shlibs Looking up shlibs dependency of liblapack.so.3 provided by 'lapack3' Found atlas3-base | lapack3 | liblapack.so.3 in /var/lib/dpkg/info/lapack3.shlibs Looking up shlibs dependency of libblas.so.3 provided by 'refblas3' Found atlas3-base | refblas3 | libblas.so.3 in /var/lib/dpkg/info/refblas3.shlibs Looking up shlibs dependency of libpthread.so.0 provided by 'libc6' Found libc6 (>= 2.6.1-1) in /var/lib/dpkg/info/libc6.shlibs Looking up shlibs dependency of libm.so.6 provided by 'libc6' Found libc6 (>= 2.6.1-1) in /var/lib/dpkg/info/libc6.shlibs Looking up shlibs dependency of liboctinterp.so provided by 'octave2.9' dpkg-shlibdeps: warning: Can't extract name and version from library name `liboctinterp.so' dpkg-shlibdeps: warning: Can't extract name and version from library name `liboctinterp.so' Found nothing dpkg-shlibdeps: failure: No dependency information found for liboctinterp.so (used by build-octave/sg.oct). I am expecting similar problems with R extensions ... where libR.so is in /usr/lib/R/lib/libR.so and not even has a SONAME ... Any ideas?
