This is bug https://ghc.haskell.org/trac/ghc/ticket/7695 and I've been bitten by it on an iconv-starved embedded system (PowerPC) for which I cross-compiled "Hello World" years ago. Cheers, Gabor Em sábado, 15 de agosto de 2015, Luka Rahne escreveu:

It turns out that issue is due to some locale settings and having impropper/not having locale setting just freeze runtime. Temporary solution is using ascii marshaling functions

myPrintStrLn str = withCAString str c_myprint

Basic stuff now works. I will have to figure out how to fix this locale issue. Binding for library will be ready soon.

Hello everyone I am new here and I have build crosscompiler for RedPitaya (http://redpitaya.com), but now i am unable to run hello world. (main = putStrLn "hello world")

Running with +RTS -Gg -RTS prints out bunch of data. What I think is going on is that GC consumes all memory.

Here is one output on device. (using larger heap just takes more time and produces longer output)

In qemu everything is working fine.

here is ghc verbose output for compilation https://gist.github.com/ra1u/ed376dc81ea21cd5a66b

If somebody has some pointers to share i would be very happy.
