http://sourceware.org/bugzilla/show_bug.cgi?id=14316 Bug #: 14316
Summary: gold build failure with recent GCC trunk because of
-Werror=unused-local-typedefs
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: gold
AssignedTo:
ian@...
ReportedBy:
ai.azuma@...
CC:
ccoutant@...
Classification: Unclassified
Recently, GCC has introduced a new kind of warning flags
`-Werror=unused-local-typedefs'
(
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33255), which warns about unused
local typedefs. And since GCC 4.8 (2012-05-04) it is enabled by `-Wall'. So,
warnings are treated as errors during the build of gold because some of gold
sources have unused local typedefs, and `-Wall' and `-Werror' are enabled.
Offending lines (of 2012-06-29 daily snapshot) are
-gold/common.cc, line 225
-gold/common.cc, line 226
-gold/dwarf_reader.cc, line 824
-gold/ehframe.cc, line 634
-gold/incremental.cc, line 2731
-gold/powerpc.cc, line 1974
-gold/arm.cc, line 3256
-gold/arm.cc, line 5212
-gold/arm.cc, line 10993
If all the offending lines are just commented out, gold is successfully built.
