未定义的引用符号'pthread_setname_np @@ GLIBC_2.12'在OpenSuse42.3上的Haskell堆栈错误 [英] undefined reference to symbol 'pthread_setname_np@@GLIBC_2.12' Haskell Stack error on OpenSuse42.3

问题描述

我已经安装了haskell stack，并且正在尝试为ghc设置相同的功能。堆栈版本是

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $版本1.5.1版本Git修订版本600c1f01435a10d127938709556c1682ecfd694e（4861提交）x86_64 hpack- 0.17.1

我更新了〜/ .stack / global-project / stack.yaml，如下所示

 ＃这是隐含的全局项目的配置文件，仅当
＃'stack'在外部运行时才会使用一个真正的项目。这里的设置不适用于所有项目的
＃默认值。要更改堆栈的默认设置，请改为编辑
＃'/home/rajkumar/.stack/config.yaml'。 
＃
＃有关堆栈配置的更多信息，请参阅

＃
 flags： {} 
 extra-package-dbs：[] 
 packages：[] 
 extra-deps：[] 
 resolver：ghc-8.2.1 
  

然后我运行堆栈设置命令并得到下面的错误 -

解决方案

<所以也许问题是你需要在你的机器上安装GLIBC_2.12而不是2.26

不，那是而不是问题。 GLIBC-2.26肯定会提供 pthread_setname_np @@ GLIBC_2.12 符号（请参阅此回答，以了解符号版本控制的工作原理）。

您可以验证GLIBC-2.26中的符号确实可用：

  $ readelf -Ws /lib/x86_64-linux-gnu/libpthread.so.0 | grep pthread_setname_np 
 89：00000000000113c0 258 FUNC GLOBAL DEFAULT 13 pthread_setname_np @@ GLIBC_2.12 
 704：00000000000113c0 258 FUNC GLOBAL DEFAULT 13 pthread_setname_np 
  

（上面的命令在具有GLIBC-2.19的系统上执行，但您将在具有GLIBC-2.26的系统上获得相同的输出）。

现在，您的 real 问题是： libHSrts.a（OSThreads.o） c 引用 pthread_setname_np （可能还有其他 pthread _ * 符号，但是您没有链接到 -pthread 或 -lpthread 标志。

我不知道在哪里添加此标志GHC，但一旦你发现，你的问题将得到解决。

I have installed haskell stack and I'm trying to setup ghc for the same. stack version is

stack --version
Version 1.5.1, Git revision 600c1f01435a10d127938709556c1682ecfd694e (4861 commits) x86_64 hpack-0.17.1

I have updated the ~/.stack/global-project/stack.yaml as below

# This is the implicit global project's config file, which is only used when
# 'stack' is run outside of a real project.  Settings here do _not_ act as
# defaults for all projects.  To change stack's default settings, edit
# '/home/rajkumar/.stack/config.yaml' instead.
#
# For more information about stack's configuration, see
# http://docs.haskellstack.org/en/stable/yaml_configuration/
#
flags: {}
extra-package-dbs: []
packages: []
extra-deps: []
resolver: ghc-8.2.1

Then I run stack setup command and got the below error -

解决方案

So maybe the problem is that you need GLIBC_2.12 installed on your machine and not 2.26

No, that is not the issue. GLIBC-2.26 most certainly provides the pthread_setname_np@@GLIBC_2.12 symbol (see this answer to understand how symbol versioning works).

You can verify that the symbol is indeed available in your GLIBC-2.26 like so:

$ readelf -Ws /lib/x86_64-linux-gnu/libpthread.so.0 | grep pthread_setname_np
    89: 00000000000113c0   258 FUNC    GLOBAL DEFAULT   13 pthread_setname_np@@GLIBC_2.12
   704: 00000000000113c0   258 FUNC    GLOBAL DEFAULT   13 pthread_setname_np

(Above command was executed on a system with GLIBC-2.19, but you'll get the same output on a system with GLIBC-2.26).

Now to what your real problem is: libHSrts.a(OSThreads.o) references pthread_setname_np (and likely other pthread_* symbols, but you are not linking with -pthread or -lpthread flag.

I don't know where to add this flag to GHC, but once you find that out, your problem will be solved.
