dh_install -O--buildsystem=cmake dh_install: missing files: usr/lib/*/lib*.so

Question

I am trying to publish my cmake project to ppa at launchpad. The project is a library named "base".

bzr builddeb -- -us -uc -sd fails with following error while trying to fake install dev version of the package.

Install the project...

how to differ builddeb for dev version of the package at installing header files

debian/rules

#!/usr/bin/make -f
# -*- makefile -*-

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

The paths in base-dev.install and base1.install are wrong.

dh_install: base-dev missing files: usr/lib/*/lib*.so
dh_install: base-dev missing files: usr/lib/*/pkgconfig/*
dh_install: base1 missing files: usr/lib/*/lib*.so.*

They will be correct as below and package can be built:

usr/lib/lib*.so
usr/lib/pkgconfig/*

usr/lib/lib*.so.*

But you will have lintian messages that /usr/lib/ is not safe for multi-arch system installations.

• Either you fix it at source level (as upstream developer), so cmake install those files to /usr/lib/<HOST-ARCH-FOLDER>/. Which is the correct way.

• Or you fix it at packaging level (as packager), by overriding installation paths in base-dev.install and base1.install

  #!/usr/bin/dh-exec
  
  usr/lib/lib*.so /usr/lib/${DEB_HOST_MULTIARCH}
  usr/lib/pkgconfig/* /usr/lib/${DEB_HOST_MULTIARCH}/pkgconfig
  
  usr/lib/lib*.so.* /usr/lib/${DEB_HOST_MULTIARCH}
