How to Test

1. Build the Docker image:

   docker build -t cpack-exercise .

2. Run the container with mounted directory:

   docker run --rm -it --mount type=bind,source="$(pwd)",target=/mnt/cpack-exercise cpack-exercise

3. Inside the container, build and test:

   cd /mnt/cpack-exercise
   mkdir build && cd build
   cmake ..
   make -j4
   
   # Test install target
   make install DESTDIR=/tmp/test-install
   tree /tmp/test-install
   
   # Create packages
   make package
   
   # Inspect packages
   tar -tzf cpackexample-0.1.0-Linux.tar.gz
   dpkg-deb -c cpackexample_0.1.0_amd64.deb
   
   # Install and run Debian package
   apt install -y ./cpackexample_0.1.0_amd64.deb
   cpackexample
   
   # Check with lintian
   lintian ./cpackexample_0.1.0_amd64.deb

Changes Made

1. Install targets added to CMakeLists.txt:

   • Executable → <prefix>/bin/
   • Library → <prefix>/lib/
   • Headers → <prefix>/include/cpackexamplelib/

2. Created cmake/CPackConfig.cmake with:

   • Package metadata (maintainer, contact, vendor, homepage, description)
   • Generates only TGZ and DEB packages
   • Debian naming scheme (DEB-DEFAULT)
   • Binary stripping enabled (CPACK_STRIP_FILES TRUE)

Lintian Output

Initial output (5 issues):

E: cpackexample: no-changelog usr/share/doc/cpackexample/changelog.gz (native package)
E: cpackexample: no-copyright-file
E: cpackexample: no-phrase Maintainer shehabsolyman134@gmail.com
W: cpackexample: extended-description-line-too-long line 2
W: cpackexample: no-manual-page [usr/bin/cpackexample]

Final output (3 issues):

E: cpackexample: no-changelog usr/share/doc/cpackexample/changelog.gz (native package)
E: cpackexample: no-copyright-file
W: cpackexample: no-manual-page [usr/bin/cpackexample]

Fixed:

• no-phrase Maintainer → Fixed maintainer format to Name <email>
• extended-description-line-too-long → Shortened package description

Binary Stripping Verification

Build directory (unstripped): 4.4M
Package (stripped):           1.7M
