无法在FreeBSD上构建Swift - REPL错误

我试图使用官方构建脚本在FreeBSD 10.2上安装Swift 3，但我无法这样做。

我收到以下错误：

fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.

ninja: build stopped: subcommand failed.

utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting

这是错误消息之前的文本：

我已经检查过Jinja，Github和Swift用户邮件列表中的开放票，但都无济于事。有没有人有办法解决吗？

你是用叉子建造的，而不是Apple的回购。

看内容的REPL.cpp：

#if defined(__APPLE__)
// FIXME: Support REPL on non-Apple platforms. Ubuntu 14.10's editline does not
// include the wide character entry points needed by the REPL yet.
#include <histedit.h>
#endif // __APPLE__

FreeBSD的editline 确实有广泛的字符入口点。所以你必须包括它。

更改

#if defined(__APPLE__)

至

#if defined(__APPLE__) || defined(__FreeBSD__)

就像在Apple回购中一样。这应该解决一个编译问题。但可能会有更多。

您可能想尝试构建官方仓库，尽管它没有将FreeBSD列为受支持的操作系统。您使用的分支在近一年内未被修改。

FreeBSD ports集合包含swift 2.2.1。如果您没有特别需要swift 3，我建议您使用它。
