How to run ghc compilation on other machines?

Question

This post is really informative of what I'm trying to achieve. I created a simple HelloUnix binary.

$ echo 'main = putStrLn "Hello Unix"' > HelloUnix.hs $ ghc -static --make HelloUnix.hs 

What created the HelloUnix binary, I was hoping the -static flag would all link inside the binary, so all that was needed to run the binary was the file itself. I transferred the binary to another unix machine, making sure that the file has the correct access privilege via chmod . Called binary, but this error appeared

 bash: ./HelloUnix: cannot execute binary file 

Any ideas on how to debug this?

EDIT: I'm currently trying to develop a distributed system, so I was hoping to just distribute the binaries to the target machines. I need a way to run the binary, even though it is running, which is the target anyway.

EDIT3: Now I am compiling the code in machine 2 and trying to run the binary on machine 1. I assume that they are both i386, so the binary should work on another machine. However, I get this error:

 HelloUnix: Cannot find /lib/ld-linux.so.2 Killed 

I think this tells me that the library ( ld-linux.so.2 ) that the binary depends on (maybe dynamic linking?) Is not on my target machine. Am I a little confused about what the -static flag did? I assumed that with the flag all dependencies will be combined into a binary file. What would be the best way to make Haskell portable code?

Answer 1

If you target the same architecture, it should work without any problems (provided that the necessary data files are also distributed).

If you target a different architecture, as in your case, you need to cross-compile for the target platform; see the GHC wiki .
