ld:无法识别的选项'--push-state--no-needed' [英] ld: unrecognized option '--push-state--no-as-needed'

问题描述

我的构建失败，并显示以下链接器错误消息:

My build fails with the following linker error message:

您可以在此处查看完整的构建日志.错误出现在2211行中，版本打印在2104ff行中.

You can see the full build log here. The error is in line 2211 and versions are printed in lines 2104ff.

哪个工具导致错误?

• gcc 7.3.0是否使用了错误的链接器标志? ld文档表示--push-state和是单独的命令.
• ld 2.28是否太旧，无法理解链接器标志?

• Is gcc 7.3.0 using an incorrect linker flag? The ld documentation indicates that --push-state and --no-as-needed are separate commands.
• Is ld 2.28 too old to understand the linker flag? The change log doesn't list anything that seems related.
• The command && /usr/bin/g++ looks odd, it should be /usr/bin/g++. Using make instead of ninja shows the same linking error.

它在同时使用gcc 7.3.0和ld 2.30的Debian测试中正确构建，但是对于Ubuntu Trusty来说似乎没有有效的binutils-2.30 ppa.

It builds correctly on Debian testing which is using gcc 7.3.0 as well and ld 2.30, but there doesn't seem to be a working binutils-2.30 ppa for Ubuntu Trusty.

如何在Travis上成功构建项目?

How do I successfully build my project on Travis?

推荐答案

GCC 7已通过 Ubuntu工具链测试PPA (适用于16.04)获得. .1和14.04).

GCC 7 is fixed with 7.3.0-16ubuntu3 (tested on Ubuntu 18.04). This version is available though the Ubuntu Toolchain Test PPA (for 16.04.1 and 14.04).

仅通过Make进行了测试，但它也可以与Ninja一起使用.启用了Sanitizer，ASan和UBsan.

Tested with Make only, but it should work with Ninja too. Both Sanitizer, ASan and UBsan, enabled.

更改日志尽管

gcc-7(7.3.0-16ubuntu3)仿生; urgency = medium

gcc-7 (7.3.0-16ubuntu3) bionic; urgency=medium

• 从gcc-7-branch更新到SVN 20180415(r259389).
  • 修复PR libstdc ++/85222.
  • Update to SVN 20180415 (r259389) from the gcc-7-branch.
    • Fix PR libstdc++/85222.

    更新:

    GCC 7( 7.3.0-16ubuntu3 )在 Ubuntu 16.04和.

    ---

    Update:

    GCC 7 (7.3.0-16ubuntu3) is still broken on Ubuntu 16.04 and earlier.

    您可以采取以下措施:

    此问题已在 Ubuntu 18.04(LTS) 的Gcc7上解决.

    The problem is fixed on Ubuntu 18.04 (LTS)'s Gcc7.

    如果无法更新，例如.在CI系统上运行，仍然可以选择使用 Docker 和最新的Ubuntu.

    If an update is not possible, eg. running on a CI system, it's still an option to use Docker and an up-to-date Ubuntu.

    仅当在启用UB Sanitizer的情况下使用GCC7时，才会出现问题.正如 tobias-brüll 在评论中指出的那样: 关闭 UB Sanitizer 可防止该错误.

    The Problem occurs only when using GCC7 with UB Sanitizer enabled. As tobias-brüll noted in the comments: Turning the UB Sanitizer off prevents the error.

    由 makerj 发布的另一种解决方法:使用 Gold Linker 不会引起问题.

    Another workaround posted by makerj: Using the Gold Linker doesn't cause the problem.

    例如.在 CMake 上通过 CMAKE_EXE_LINKER_FLAGS :

    cmake -DCMAKE_EXE_LINKER_FLAGS=-fuse-ld=gold ..
