From 9c2126c963582ce0100745ca84de4cd2e6e4e212 Mon Sep 17 00:00:00 2001 From: Adam Duskett Date: Tue, 11 Feb 2020 08:34:00 -0800 Subject: [PATCH] package/libiberty: new package Some packages, like prelink-cross, want to use libiberty but do not bundle their own instance (which is good!). However, libiberty is made for being bundled in packages: all GNU packages that use libiberty (gcc, Binutils, gdb, et al...) all have their own bundled variant. This common practice means that there is no official upstream for libiberty, the closest being as part of the combined Binutils-gdb tree. So we introduce a new host-only package, that installs just libiberty from a Binutils released tarball. Again, as packages usually bundle libiberty, it usually only installs a static version. Furthermore, it does not obey the usual --enable-shared and --disable-static flags; it only ever builds a static version. Furthermore, -fPIC is not used with this library, but some packages may pick it to build shared objects. This behavior is the case for host-gdb, for example, which accidentally picks that library instead of its internal one. So, rather than fix the various gdb versions and variants we can use, we ensure that the libiberty we install is usable in shared objects, and we always build before host-gdb.
