Summary: Building CodeBlocks on Windows using mingw gcc 4.6.1
"-flto -fuse-linker-plugin" results in many linker
stage errors
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sources.redhat.com
ReportedBy: xunxun1...@gmail.com
Host: i686-pc-mingw32
Target: i686-pc-mingw32
Build: i686-pc-mingw32
Hi, all
My gcc4.6.1 configure with :
./configure --prefix=/mingw --host=i686-pc-mingw32 --build=i686-pc-mingw32
--target=i686-pc-mingw32 \
--with-lto-plugin --with-host-libstdcxx=-lstdc++ --disable-bootstrap
--disable-werror --with-arch=i686 --with-tune=generic \
--enable-languages=c,c++,fortran --enable-libgomp --enable-threads=win32
--enable-lto --with-system-zlib \
--enable-libstdcxx-debug --enable-version-specific-runtime-libs
--enable-fully-dynamic-string \
--disable-sjlj-exceptions --with-dwarf2 --disable-symvers
--enable-checking=release \
--enable-plugins --enable-cloog-backend=isl --enable-static
--disable-shared \
--disable-nls --disable-win32-registry
My ld version is : 2.21.52.20110708
When I build Code::Blocks, if I add "-flto" to the compiler option, and add
"-Wl,-O1 -Wl,--sort-common -Wl,--as-needed -s -flto -fuse-linker-plugin" to the
linker option, that will result in many linker stage errors:

--------------------------------------------------------------------------------
But either .objs\sdk\wxpropgrid\src\*.o or libwxmsw28u.a don't have any symbols
like "*****.local.****", the libwxmsw28u.a only have the symbols like
"_imp___ZTV17wxStringTokenizer".
I don't know how the "*****.local.****" symbols come out?
It's a gcc lto plugin bug or ld bug?
I remove "-Wl,-O1 -Wl,--sort-common -Wl,--as-needed", and it also has the
problem.
ps: other linker option like "-Wl,--enable-auto-image-base
-Wl,--add-stdcall-alias -Wl,--enable-auto-import" is Code::Blocks's default
option.
