Bug #: 52405
Summary: undefined references in shared library when linking
the shared library with -flto
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: doko@gcc.gnu.org
seen with the 4.6 branch, and 4.7 20120223. The object files are built with
-flto as well. Linking the shared library with -flto results in unresolved
symbols when linking against the share library. Not building the shared library
with -flto lets the launcher link succeed.
the object files (x86_64-linux-gnu) including the build script build.sh can be
found at
http://people.debian.org/~doko/tmp/hs.tar.xz
The undefined symbols come from inline template definitions in a header file.

As it is inlines and you use -fvisibility=hidden I expect that the -Xlinker --version-script=mapfile_reorder is not re-applied after final link optimization but only to the (fat) object file result from compile. So some functions may not be catched by the version script globbing (or they are renamed as comdats are brought local, and thus may no longer match any of the globs)? Please help reducing this on your side. ^ permalink raw reply [flat|nested] 5+ messages in thread
