swift - 苹果 swift 错误没有这样的模块'Foundation'

Question

我的一位同事正在尝试在 ppc64le Ubuntu16.04 上构建 apple swift。是的，我知道苹果 swift 在 ppc64le 上尚未完全支持，但不知何故，她使用https://github.com/ppc64le/build-scripts/blob/60b7885f4f0915a8671b3cfb86ddbb65f9b988a8/swift/swift41_ubuntu_16.04的构建脚本在ppc64le 上构建了它.sh。

但是，在运行代码时，会产生以下错误“没有这样的模块'Foundation'”

root@ubuntu-sun:/home/ServerSideSwiftTap# swift build 编译 Swift 模块“ServerSideSwiftTap”（3 个来源）/home/ServerSideSwiftTap/main.swift:1:8：错误：没有这样的模块“Foundation”

我检查了我的构建脚本，似乎这也构建了 swift-corelibs-foundation。有什么建议吗？

已编辑

我想我通过将以下目录插入 PATH 变量来解决“基础”模块问题。

$ export PATH=/root/swift-source2/Ninja-ReleaseAssert+stdlib-Release/swiftpm-linux-powerpc64le:$PATH

但是现在我收到以下错误“没有这样的模块'Dispatch'”。

root@ubuntu-sun:/home/ServerSideSwiftTap# swift build 编译 Swift 模块“Schrodinger”（1 个来源）编译 Swift 模块“Cheetah”（7 个来源）编译 Swift 模块“CryptoKitten”（10 个来源）编译 Swift 模块“BSON”（ 21 个来源）/home/ServerSideSwiftTap/.build/checkouts/Schrodinger.git--4853784622312920879/Sources/Schrodinger.swift:1:8: 错误：没有这样的模块“调度”导入调度 ^ 错误：终止（1）：/root /swift-source2/Ninja-ReleaseAssert+stdlib-Release/swiftpm-linux-powerpc64le/powerpc64le-unknown-linux/release/swift-build-tool -f /home/ServerSideSwiftTap/.build/debug.yaml 主要输出：

我四处搜索，我想我必须为 swift-corelibs-libdispatch 执行“sudo make install”。但是，它最终会出现以下错误，这对我来说看起来很讨厌。

以防万一，下面是ServerSideSwiftTap的源代码。
