Bug #: 15477
Summary: gld does not understand mapfiles correctly
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sourceware.org
ReportedBy: joerg.schill...@fokus.fraunhofer.de
Classification: Unclassified
gld does not work with typical mapfiles such as used by
e.g.OpenSolaris
To check the problem, get a recent cdrtools tarball from:
ftp://ftp.berlios.de/pub/cdrecord/alpha/ and patch the Linux configuration
to enable map files:

Now chdir into "libschily" and call: "make LINKMODE=dynamic"
This results in:
