How to load private shared libraries within "rules" make file in deb-packaging

I am making a dabian binary package for local use. dpkg-buildpackage -rfakeroot is failed due to below error.

find /home/dwft78/project/CoreScanner/cscore-1.0/lib -name "libcs*" -type f -exec cp -f {} /home/dwft78/project/CoreScanner/cscore-1.0/debian/cscore/opt/motorola-scanner//bin \;
find /home/dwft78/project/CoreScanner/cscore-1.0/lib -name "libcs*" -type l -exec cp -Rf {} /home/dwft78/project/CoreScanner/cscore-1.0/debian/cscore/opt/motorola-scanner//bin \;

dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2

all these libraries are generating to "/home/dwft78/project/CoreScanner/cscore-1.0/lib/Linux/x86_64"

Contents of debian/rules is

#!/usr/bin/make -f
# -*- makefile -*-
# Sample debian/rules that uses debhelper.
# This file was originally written by Joey Hess and Craig Small.
# As a special exception, when this file is copied by dh-make into a
# dh-make output file, you may use that output file without restriction.
# This special exception was added by Craig Small in version 0.37 of dh-make.

# Uncomment this to turn on verbose mode.
#export DH_VERBOSE=1

export DH_COMPAT=5

%:
        dh $@

As the error message indicates "To help dpkg-shlibdeps find private libraries, you might need to set LD_LIBRARY_PATH" how can I load those inside debian/rules file ? or otherwise is this occurred due to an another reason ?

Solution

  • Something like that could just do the trick:

    #!/usr/bin/make -f

export DH_COMPAT=5 # though I don't know what for...

%:
    dh $@

override_dh_shlibdeps:
    dh_shlibdeps -l$(shell pwd)/lib/Linux/$(DEB_BUILD_GNU_CPU)

    Edit

    I just remembered there was an option to dh_shlibdeps which even got attention regarding problems with setting LD_LIBRARY_PATH in cross-builds, so this should be the option of choice. Disclaimer: I didn't test it. (I'm curious if it works out, though.) See the dh_shlibdeps manual page.
