在使用堆栈安装构建echidna时显示缺少的库: ff

Question

我正在尝试使用stack install构建echidna。

https://github.com/crytic/echidna

在171/178的进度状态下安装时，我不断地得到缺少的库错误。

我认为与其说是库错误，不如说是堆栈错误。显示的错误如下

我试过安装这个库，但是没有得到任何这样的sort.ye的C库

所以，我已经安装了所有的库

sudo apt-get install lib*ff*-dev

还没起作用。

    Cabal-simple_mPHDZzAJ_2.2.0.1_ghc-8.4.3: Missing dependency on a foreign
    library:
    * Missing (or bad) C library: ff
    This problem can usually be solved by installing the system package that
    provides this library (you may need the "-dev" version). If the library is
    already installed but in a non-standard location then you can use the flags
    --extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the
    library file does exist, it may contain errors that are caught by the C
    compiler at the preprocessing stage. In this case you can re-run configure
    with the verbosity flag -v3 to see the error messages.

堆栈安装必须找到这个库，并成功地安装我正在使用的库。

Answer 1

因此，从上面提供的错误中可以清楚地看到，安装无法找到libff文件。

最好的解决方案是手动构建libff库，并在它应该在的地方复制所需的构建。

调试问题的最佳方法是仔细查看已执行的命令，并试图找到libff应该在哪些地方出现.

查看第二个错误行，即它试图在这里执行的完整命令，我看到了正在执行的以下选项

--extra-include-dirs=/usr/local/opt/readline/include --extra-lib-dirs=/usr/local/opt/readline/lib

为了解决这个问题，我查找了所需的libff库，并从GitHub中克隆了它。我克隆了所需的依赖项，并将它们放在应该是的目录中。

https://github.com/scipr-lab/libff

然后，我按照“构建指南”构建所需的库。

然后，随着超级用户的启动，我创建了目录，/usr/local/opt/readline/lib和/usr/local/opt/readline/include，并解决了这个问题。并将所需的构建粘贴在其中。

再次使用了stack install，它起了作用。

注意:我认为许多初学者在安装所需的工具时可能会遇到类似的问题。这些小小的想法可能对他们有帮助。
