未定义的符号引用'pthread_setname_np@@GLIBC_2.12' OpenSuse42.3上的Haskell堆栈错误

我已经安装了haskell堆栈，我正在尝试设置相同的ghc . 堆栈版本是

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

我已经更新了〜/ .stack / global-project / stack.yaml，如下所示

# 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

然后我运行stack setup命令并得到以下错误 -

stack setup

  for more information. Exception was:

    所以问题可能是你需要在你的机器上安装GLIBC_2.12而不是2.26

    不，这不是问题 . GLIBC-2.26肯定提供 pthread_setname_np@@GLIBC_2.12 符号（请参阅this answer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，如下所示：

    $ 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

    （上述命令在具有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） .

    现在你真正的问题是： libHSrts.a(OSThreads.o) 引用 pthread_setname_np （可能还有其他 pthread_* 符号，但你没有链接 -pthread 或 -lpthread 标志 .

    我不知道在GHC上添加这个标志的位置，但一旦你发现了，你的问题就会得到解决 .
