I am trying to install frrouting on a docker container (ubuntu-based) and I am still fighting againt dependency hell. I have already installed : readline autoconf libtool libjson-c-dev tar build-essential libxml2 libxml-libxml-perl dialog pkg-config libglib2.0-dev But I am stuck with "libcares", which I cannot find as a package: ------------------ configure: error: Package requirements (libcares) were not met: No package 'libcares' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables CARES_CFLAGS and CARES_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. ------------------ Any hint?
