Package: libgraphicsmagick++1-dev Version: 1.3.25-8 Severity: important Dear Maintainer,
After the package is installed, $ GraphicsMagick++-config --ldflags --libs mentions -lwebp as its dependencies. However, it is not automatically installed as part of the dependencies, making compilations that link the library in this package fail: /usr/bin/ld: cannot find -lwebp This can be fixed manually by installing libwebp-dev. Somewhere down the dependency chain of the libgraphicsmagick++* packages, the dependency on libwebp-dev is missing and needs to be added. This was observed in Jessie and Stretch. -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libgraphicsmagick++1-dev depends on: ii libgraphicsmagick++-q16-12 1.3.25-8 ii libgraphicsmagick1-dev 1.3.25-8 libgraphicsmagick++1-dev recommends no packages.
