Source: libunistring Severity: normal Tags: patch User: [email protected] Usertags: ppc64el
Dear Maintainer, The package libunistring fails to build from source on ppc64el. Using dh-autoreconf fixes that situation and the package builds successfully. There are 2 patches attached. The dh-autoreconf one just includes dh-autoreconf to the build. The other one, which fixes detection of floating point endianness has been gathered from Ubuntu, created by Colin Watson. Thanks Fernando -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: ppc64el (ppc64le) Kernel: Linux 3.13-1-powerpc64le (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash
