Question

我正在使用from the github repo从源代码构建NIX。一切都按照说明进行，但最终在make失败了。

我得到的错误是

caffeinated:nix sudoankit$ make all

我现在该如何进行构建？

Answer 1

您通过Homebrew安装的C ++库依赖项（即Boost / Yaml）是使用public class BuyAHouseInc { public void displayClient(String firstName, String surname, String address, int budget) { System.out.println("Client Name: " + firstName + " " + surname); System.out.println("Address: " + address); System.out.println("Budget: " + "€" + budget); } }编译的。结果是：缺少与GCC编译时STL交互产生的一些符号。

因此，您必须使用clang++进行编译，例如像这样：

clang++

查看git存储库，作者甚至在其Travis CI configuration中启用了Mac OS X：

$ mkdir build
$ CXX=clang++ CC=clang cmake -DCMAKE_BUILD_TYP=Release ..
$ make

但他们也明确排除了Mac OS X上的GCC版本：

os:
  - linux
  - osx

在Mac OS X上的libnix.1.1.0.dylib上失败
