Bug 97009 – [Qt] Gold linker isn't used on Ubuntu

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

Tools/qmake/mkspecs/features/unix/default_post.prf:
----------------------------------------------------
!scratchbox:!mac:exists(/usr/bin/ld.gold) {
    # Upstream gcc 4.7 does not support the -fuse-ld=gold option ( see: http://sourceware.org/ml/binutils/2011-01/msg00178.html )
    isEqual(QT_GCC_MAJOR_VERSION, 4):lessThan(QT_GCC_MINOR_VERSION, 7):QMAKE_LFLAGS += -fuse-ld=gold
}

It seems -fuse-ld=gold doesn't work on Ubuntu 11.10 (maybe other distros and other Ubuntus have same problem)

http://manpages.ubuntu.com/manpages/oneiric/man1/arm-linux-gnueabi-gcc-4.4.1.html
----------------------------------------------------------------------------------
-fuse-ld=gold
    Use the gold linker instead of the default linker.  This option is
    only necessary if GCC has been configured with --enable-gold=both
    or --enable-gold=both/ld.  Note: Backported for Debian/Ubuntu from
    GCC 4.5.

-fuse-ld=bfd
    Use the ld.bfd linker instead of the default linker.  This option
    is only necessary if GCC has been configured with
    --enable-gold=both/gold.  Note: Backported for Debian/Ubuntu from
    GCC 4.5.

But the manualt of gcc doesn't contain this options - http://manpages.ubuntu.com/manpages/oneiric/man1/gcc-4.6.1.html
It seems Ubuntu's GCC doesn't build with this option, so -fuse-ld=gold won't work at all,
we need better way to force using gold linker.

forcing gold linker was removed, so it isn't problem anymore:
