Question

我已经安装了haskell堆栈，我正在尝试为此设置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
The GHC located at /home/user/.stack/programs/x86_64-linux/ghc-tinfo6-8.2.1/bin/ghc failed to compile a sanity check. Please see:

http://docs.haskellstack.org/en/stable/install_and_upgrade/

for more information. Exception was:
Running /home/user/.stack/programs/x86_64-linux/ghc-tinfo6-8.2.1/bin/ghc /tmp/stack-sanity-check6389/Main.hs -no-user-package-db in directory /tmp/stack-sanity-check6389/ exited with ExitFailure 1

/usr/bin/ld.bfd: cannot find -lgmp
collect2: error: ld returned 1 exit status
`gcc' failed in phase `Linker'. (Exit code: 1)

如何解决此问题？

Answer 1

我能够解决此错误。

使用以下命令验证gmp是否已在opensuse linux上安装。

sudo ldconfig -p | grep libgmp
libgmp.so.10 (libc6,x86-64) => /usr/lib64/libgmp.so.10

如果不存在，请使用以下命令

进行安装

sudo zypper install libgmp10

在同一文件夹中创建lib文件的链接。实施例

sudo ln /usr/lib64/libgmp.so.10 /usr/lib64/libgmp.so

希望这对某人有帮助。
