我在新安装的Ubuntu 18.04计算机上，通过apt-get安装了clang和llvm，并从swift.org安装/下载了Swift
test.swift 文件：
import Foundation
let s: String = ":)"
let d: Date = Date()
print("Hello Foundation! \(s) - \(d)")
如果我跑步
swiftc test.swift -o test && ./test
它输出 Hello Foundation！ ：）-应当按2018年12月12日08:56:31 +0000 进行操作。
然后我用
生成LLVM位代码swiftc -emit-bc test.swift -o test.bc
并通过 lli 执行：
lli \
-load=/usr/local/lib/swift/linux/libFoundation.so
-load=/usr/local/lib/swift/linux/libswiftCore.so
-load=/usr/local/lib/swift/linux/libswiftGlibc.so
-load=/usr/local/lib/swift/linux/libswiftSwiftOnoneSupport.so
test.bc
与上面的 Hello Foundation输出相同。 ：）-2018-09-12 08:56:31 +0000
所以我拿了 llc 并将其编译为目标文件：
llc -filetype=obj test.bc -o test.o
之后，我想将此文件链接到具有以下内容的可执行文件：
ld -L /usr/local/lib/swift/linux/*.so -dynamic-linker /lib64/ld-linux-x86-64.so.2 test.o -o test -e main
产生：
file test
test: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, not stripped
但是如果我运行它：
.test/: error while loading shared libraries: libFoundation.so: cannot open shared object file: No such file or directory
奇怪的部分现在出现了：
ldd test

所有未建立的库（如libFoundation.so）均被列出两次。一旦找不到，然后找到。
为什么？这可能是为什么它不执行的问题吗？
答案 0 :(得分：0)
snap安装swift都有关：
sudo snap install swift-lang --edge --devmode
和dnf
sudo dnf install swift-lang
