Package: google-perftools Version: 2.2.1-0.1 Severity: normal Tags: patch User: debian-...@lists.debian.org Usertag: arm64
This package is currently FTBFS on the arm64 architecture. See build log at: https://buildd.debian.org/status/fetch.php?pkg=google-perftools&arch=arm64&ver=2.2.1-0.1&stamp=1411541907 This patch adds support for the architecture, based on the existing arm (32bit) support. We are trying to get this arch into good shape for release with jessie, so an upload with this fix soon would be greatly appreciated. I am happy to NMU the package if you prefer, and will do so if I do not hear from you in a few days. thanks
