I have packaged a library named base and uploaded to my ppa:satyagowtham-k-gmail/ferryfair.ppa. launchpad has successfully built the base package and I successfully installed it by sudo apt install base-dev. Now I am packaging another library called logger which depends on base.

I have added my ppa to pbuilder chroot by

$ sudo cp ~/pbuilder/xenial-base.tgz /var/cache/pbuilder/base.tgz
$ pbuilder login --save-after-login
# apt-add-repository ppa:satyagowtham-k-gmail/ferryfair.ppa
# apt-get update
# exit

pbuilder-dist xenial build logger_1.0-0ubuntu1.dsc is giving below error

...

  • The problem resides in the base package. It does install the shared object in a wrong path

      /usr/lib/x86_64/
    

    when it should be in

      /usr/lib/x86_64-linux-gnu/
    
  • Following from your previous question, you have made some changes to CMakeLists.txt to install the library not in /usr/lib/ using:

      include(TargetArch.cmake)
      target_architecture(arch)
      ...
      install(TARGETS ${PROJECT_NAME} DESTINATION lib/${arch})
      ...
      install(FILES "${CMAKE_CURRENT_SOURCE_DIR}/${PROJECT_NAME}.pc"
          DESTINATION lib/${arch}/pkgconfig
          RENAME "lib${PROJECT_NAME}.pc")
    

    The new variable ${arch} is replaced by x86_64.

  • I could find a Debian manual explains the move to MultiArch for cmake projects.

    A new GNUInstallDirs module was added to cmake v3.3.

    1. Include the new module for MultiArch paths support

       include(GNUInstallDirs)
      
    2. Then use CMAKE_INSTALL_LIBDIR (/usr/lib/<triplet>) variable instead.

  • Just small note about base package naming to follow Debian policy the binary file don't contain executable files. Hence, better to name them with lib prefix, libbase1 & libbase-dev.

    I couldn't pbuilder-dist: base1 base-dev Untrusted packages could compromise your system's security. anyway I have uploaded the dsc and the package is successfully hosted in the ppa.

  • as you suggested I have added lib prefix. now there is a lintian warning W: libbase1: empty-binary-package. Yep I have seen the contents of .deb: It got only 2 files changelog.Debian.gz and copyright

  • @neckTwi, Have you renamed the debian/*.install files?

  • there are no .install files

  • this time I am using gbp buildpackage --git-upstream-tag='v1.0' --git-debian-branch=ubuntu/xenial --git-upstream-branch=master to generate deb files
