Summary: Improve the error message for linking failure
Product: binutils
Version: 2.20
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sources.redhat.com
ReportedBy: qiao...@gentoo.org
I'm building a C++ shared library project. When I add "--coverage" to CXXFLAGS,
the project fails to compile because libtool uses --nostdlib. The error message
is not that helpful:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/../../../../x86_64-pc-linux-gnu/bin/ld:
.libs/variable_printer: hidden symbol `atexit' in
/usr/lib64/libc_nonshared.a(atexit.oS) is referenced by DSO
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/../../../../x86_64-pc-linux-gnu/bin/ld:
final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
make[1]: *** [variable_printer] Error 1
The message doesn't tell where the hidden symbol is referenced from. I need to
run readelf to figure what's going on. I wonder if the error output could be
improved to show the information.
