Source: gdb Version: 7.6-2 Severity: important Tags: patch, upastream Usertags: hurd User: debian-h...@lists.debian.org
Hello, gdb does not build from source any longer since gdb-multiarch packages was enabled in 7.4.1-1. The build problems is due to a PATH_MAX issue in gdb/nto-tdep.c:nto_init_solib_absolute_prefix(). The attached patch, solve_PATH_MAX_issue.patch, solves this build problem. This patch has also been submitted upstream, see http://sourceware.org/ml/gdb-patches/2013-05/msg00878.html Thanks!
