Package: libgnutls28-dev Version: 3.5.9-1 Severity: serious gnutls.pc from experimental contains Requires.private: nettle, hogweed, libtasn1, libidn2, p11-kit-1, zlib
The package depends on libidn11-dev which ships libidn.pc though. libidn2.pc is not available in the archive afaics. I suppose you want libidn2-0-dev, but that package doesn't ship a libidn2.pc (maybe a bug in that package). As a result, building against libgnutls28-dev results in a FTBFS, like e.g. in https://buildd.debian.org/status/fetch.php?pkg=rsyslog&arch=ppc64&ver=8.25.0-1&stamp=1487703642&raw=0 Regards, Michael -- System Information: Debian Release: 9.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.utf8, LC_CTYPE=de_DE.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libgnutls28-dev depends on: ii libc6-dev [libc-dev] 2.24-9 ii libgnutls-dane0 3.5.8-3 ii libgnutls-openssl27 3.5.8-3 ii libgnutls30 3.5.8-3 ii libgnutlsxx28 3.5.8-3 ii libidn11-dev 1.33-1 ii libp11-kit-dev 0.23.3-5 ii libtasn1-6-dev 4.10-1 ii nettle-dev 3.3-1 ii zlib1g-dev 1:1.2.8.dfsg-5 libgnutls28-dev recommends no packages.
