我正在尝试使用官方构建脚本但我无法这样做。
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

我已在 Jinja、Github 和 Swift 用户邮件列表中查找未解决的票证，但均无济于事。有人有解决方案吗？
答案1
您正在构建叉，不是 Apple repo。
看着那（这内容的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 的编辑行做有宽字符入口点。所以你必须把它包括进去。
改变
#if defined(__APPLE__)
到
#if defined(__APPLE__) || defined(__FreeBSD__)
就像在苹果仓库。这应该可以修复一个编译问题。但可能还有很多问题。
您可能想尝试构建官方 repo，尽管它没有将 FreeBSD 列为受支持的操作系统。您使用的分支近一年没有修改过。
FreeBSD ports collection 包含swift 2.2.1。如果你不是特别需要swift 3，我建议你使用它。
