OpenSuse42.3 上对符号 'pthread_setname_np@@GLIBC_2.12' 的未定义引用 Haskell Stack 错误

Question

我已经安装了 haskell 堆栈，我正在尝试设置 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

# 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

然后我运行堆栈设置命令并得到以下错误 -

  stack setup
  The GHC located at /home/rajkumar/.stack/programs/x86_64-linux/ghc-8.2.1/bin/ghc failed to compile a sanity check. Please see:

  for more information. Exception was:

所以问题可能是您需要在机器上安装 GLIBC_2.12 而不是 2.26

不，这不是的问题。 GLIBC-2.26 肯定会提供 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）。

您可以像这样验证该符号在您的 GLIBC-2.26 中确实可用：

$ 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

（上述命令在 GLIBC-2.19 系统上执行，但在 GLIBC-2.26 系统上您将获得相同的输出）。

现在你的真正问题是什么：libHSrts.a(OSThreads.o) references pthread_setname_np（可能还有其他pthread_*符号，但你没有链接到-pthread或-lpthread 标志。

我不知道在哪里添加这个标志到 GHC，但是一旦你发现了，你的问题就会解决。
