如何运行砖应用程序？

Question

I need to install bhoogle . I've already installed cabal by stack install hoogle command and I've created default database. I don't know how to run application with the GUI. I have bhoogle repo downloaded on my Mac and stack ghci Setup nor stack ghci App/Main doesn't work. No GUI is being displayed. I think that all the requirements are satisfied, but the method of running the app is wrong.

Answer 1

Although your solution works, I don't think it's ideal, since the point of having entrypoints defined in a .cabal file is so that you can let stack do the grunt work (navigating the directories to the main hs file).

If you want to install bhoogle system-wide, as its purpose suggests, then you can stack install bhoogle from anywhere outside of a stack directory.

If, however, you want to compile and run it without installing it, bhoogle uses make , so you can build it with make and then fetch the executable from the .stack-work directory. Alternatively, from stack 1.9.1, you can use stack run , an analog to cabal run . For earlier versions of stack, you can use stack build --exec bhoogle .

关键是使用以下命令运行它： stack App/Main.hs 。
