- 在GCC-6.1中不使用金链接器 [英] -fsanitize not using gold linker in GCC-6.1

问题描述

更新（2016年9月30日）

gcc-6.2的Ubuntu版本（（Ubuntu 6.2.0-3ubuntu11〜16.04）6.2.0 20160901）no

---

我使用gcc-6.1的Ubuntu版本（1）（（Ubuntu 6.1。 1-3ubuntu11〜14.04.1）6.1.1 20160511），GNU binutils 2.24和支持GLIBCXX_3.4.22的libstdc ++。即使是在一个简单的hello world程序中，指定一个杀毒软件也不会强制使用gold linker。

main.cpp

  #include< iostream> 
 int main（）{
 std :: cout<< 你好，世界！\ n; 
 
 $ / code> 

编译和链接



  g ++ -fsanitize = address -c -o main main.cpp 
 g ++ -fsanitize = address -o main main.o 
  

给出错误



  / usr / bin / ld：无法识别的选项'--push-state'
 / usr / bin / ld：对使用信息使用--help选项
 collect2：错误：ld返回1退出状态
  

这表明 -fsanitize 选项没有选择黄金链接器。当然，简单的解决方法是在链接过程中使用 -fuse-ld = gold ，但以前的gcc版本在使用杀毒软件时并不需要。例如，这个代码在gcc-5.3和4.9（都是Ubuntu版本）下工作得很好。是否有其他人在非Ubuntu版本的gcc-6.1上遇到这个问题？ Ubuntu构建破坏了吗？

Update (30-Sept-2016)

The Ubuntu build of gcc-6.2 ((Ubuntu 6.2.0-3ubuntu11~16.04) 6.2.0 20160901) no longer has this issue.



I'm using the Ubuntu build of gcc-6.1[1] ((Ubuntu 6.1.1-3ubuntu11~14.04.1) 6.1.1 20160511), GNU binutils 2.24, and libstdc++ with GLIBCXX_3.4.22 support. Even on a simple "hello world" program, specifying a sanitizer is not forcing use of the gold linker.

main.cpp

#include <iostream>
int main() {
    std::cout << "Hello, world!\n";
}
Compiling and linking
g++ -fsanitize=address -c -o main main.cpp
g++ -fsanitize=address -o main main.o
gives the error
/usr/bin/ld: unrecognized option '--push-state'
/usr/bin/ld: use the --help option for usage information
collect2: error: ld returned 1 exit status
Which indicates the -fsanitize option isn't selecting the gold linker. Of course, the simple fix is to use -fuse-ld=gold during linking, but previous builds of gcc didn't need this when using the sanitizers. For example, this code works perfectly fine under gcc-5.3 and 4.9 (both are Ubuntu builds). Is anyone else having this issue with non-Ubuntu builds of gcc-6.1? Are the Ubuntu builds broken?

解决方案
For me the same problem and same solution using
 -fuse-ld=gold
