从可执行文件中查找 ghc 版本

Question

我的系统中有一个可执行文件，它是通过 GHC 编译器构建的。有没有办法找到用于构建它的 GHC 版本？

Answer 1

是的，您可以将 --info 标志传递到 RTS 选项中以找出答案：

$ tldr +RTS --info -RTS
 [("GHC RTS", "YES")
 ,("GHC version", "8.6.5")
 ,("RTS way", "rts_thr")
 ,("Build platform", "x86_64-unknown-linux")
 ,("Build architecture", "x86_64")
 ,("Build OS", "linux")
 ,("Build vendor", "unknown")
 ,("Host platform", "x86_64-unknown-linux")
 ,("Host architecture", "x86_64")
 ,("Host OS", "linux")
 ,("Host vendor", "unknown")
 ,("Target platform", "x86_64-unknown-linux")
 ,("Target architecture", "x86_64")
 ,("Target OS", "linux")
 ,("Target vendor", "unknown")
 ,("Word size", "64")
 ,("Compiler unregisterised", "NO")
 ,("Tables next to code", "YES")
