Re: [Mingw-w64-public] how to use ld.gold as the linker?
I suggest you take a look at precompiled headers. (https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html) According to my experience it could cut C++ compile time by about 40% on Windows (and about 60%-70% on Linux). -- Best regards, lh_mouse 2015-05-18 - 发件人：zhangxinghai zxh19750...@163.com 发送日期：2015-05-18 08:39 收件人：zhangxinghai 抄送：mingw-w64-public 主题：Re: [Mingw-w64-public] how to use ld.gold as the linker?

Re: [Mingw-w64-public] how to use ld.gold as the linker?
AFAIK, ld.gold is designed to output only ELF [1] binaries (and the
specialization is what makes it superior to GNU ld when outputting ELF),
while Windows use PE [2] binaries.
So you cannot.

Hi,all
My OS is xp sp3
I used the i686-4.9.2-release-posix-dwarf-rt_v4-rev2.7z build from site
http://sourceforge.net/projects/mingw-w64
I write a helloworld.cpp program
#includestdio.h
#includeiostream
int main()
{
int i1=1,i2=2;
int sum = i1 + i2;
printf(%d\n,sum);
return 0;
}
when I use g++ -o hello.exe hello.cpp,It works well.Now I want it to be
linked with ld.gold,I use g++ -o hello.exe hello.cpp -fuse-ld=gold -v,I get
following error,what is the problem and how to resolve it.
Great thanks
