So I've been trying to install Threepenny GUI for a Haskell college assignment the last few hours without any avail. When stack attemps to build the 'snap-core' dependency, I get the following error:
snap-core > configure
snap-core > Configuring snap-core-1.0.5.0...
snap-core > build
snap-core > Preprocessing library for snap-core-1.0.5.0..

-- While building package snap-core-1.0.5.0 (scroll up to its section to see the error) using:
C:\Users\User\AppData\Roaming\stack\setup-exe-cache\x86_64-windows\Cabal-simple_Z6RU0evB_3.6.3.0_ghc-9.2.5.exe --verbose=1 --builddir=.stack-work\dist\8a54c84f build --ghc-options " -fdiagnostics-color=always"
Process exited with code: ExitFailure 1
I have tried building the dependencies of snap-core with 'stack build --dependencies-only snap-core' with no avail. I've also tried to build the 'time' package on it's own with no avail either. My stack version is up to date also. Any ideas..?
I have been learning haskell using the atom editor on Windows 7. This has worked fine until I created a .cabal file. Now I continuously get red error messages.In fact it is so bad to be unusable as the error messages keep popping up faster than you can delete them. The haskell program is a trivial hello world.
module Main where
main :: IO ()
main = putStrLn "Hello from Haskell!"
The .cabal file is as follows:
-- Initial hello-haskell.cabal generated by cabal init. For further

a quick guess, without a computer to confirm this. did run into a similar situation and delete the build folder . this happend when I run yesod devel inside the project, and afterward did open the project folder in atom editor, usin ghc-mod on Windows 10. I'll update this answer when I'm back at a computer and learn how to format responses here on stackoverflow. don't delete the build folder if you want to use it later, I assume there is some configuration in the atom addon or in a configuration file for ghc-mod or maybe wrap the ghc-mod configuration to use spesific version of library.
I upgraded to ghc-mod-5.6.0.0. I also have ghc-mod installed in 3 places. As my PATH points to all 3 I have temporarily renamed those old exe files and only using the latest 5.6.0.0.
I tried to install Yesod with Cabal. Yesod depends on Cryptonite to work, however it failed to install. Here is the error message:

Thank you
The relevant part seems to be the next:
cbits/ed448/x448.c:21:9:
error: unknown type name ‘__uint128_t’
typedef __uint128_t decaf_dword_t;

AFAIK __uint128_t is a gcc extension, so it is probably not available with your compiler. Try to contact package maintainer.
ADD: Are you using i686 architecture? Looks like the issue is already reported.
I'm trying to reproduce the examples of "Seamless R and C++ Integration with Rcpp" book, but some codes are not running. Specifically, it is on chapter 5, Section 5.2.3 and the code follows above:
#ifndef _mypackage_RCPP_HELLO_WORLD_H
#define _mypackage_RCPP_HELLO_WORLD_H
#include <Rcpp.h>
/*
* note : RcppExport is an alias to 'extern "C"' defined by Rcpp.
*
* It gives C calling convention to the rcpp_hello_world
* function so that it can be called from .Call in R.
* Otherwise, the C++ compiler mangles the
* name of the functioand .Call can’t find it.
* It is only useful to use RcppExport when the function
* is intended to be called by .Call. See the thread
* http://thread.gmane.org/gmane.comp.lang.r.rcpp/649/focus=672
* on Rcpp-devel for a misuse of RcppExport 19
*/
RcppExport SEXP rcpp_hello_world();
#endif
and the next is
#include "rcpp_hello_world.h"
SEXP rcpp_hello_world() {
using namespace Rcpp;
CharacterVector x = CharacterVector::create( "foo", "bar" ) ;
NumericVector y = NumericVector::create( 0.0, 1.0 ) ;
List z = List::create( x, y ) ;
return z ;
}
The error showed by R is
Error in .Call("rcpp_hello_world", PACKAGE = "mypackage") :
"rcpp_hello_world" not available for .Call() for package "mypackage"
Have anyone faced a problem like this?
Thanks in advance!
When I try to tip

I got an error like this

Now, I don't understand where to use the code written in "Listing 5.4", Do I need to write it or this is created automatically?
This example (and chapter) discusses how to build (and load) an entire package, here called mypackage.
Did you actually create, compile and load mypackage?
This works, as we do this each and every time the unit tests run.
Edit: Here is a full log for you
R> library(Rcpp)
R> Rcpp.package.skeleton("mypackage") ## page 66, Section 5.2.1

I am trying to call Haskell functions from python.
I have the following make file:
GHC=ghc
GHC_RUNTIME_LINKER_FLAG=-lHSrts-ghc7.4.1
libffi-example.so: Example.o wrapper.o
$(GHC) -o $# -shared -dynamic -fPIC $^ $(GHC_RUNTIME_LINKER_FLAG)
Example_stub.h Example.o: Example.hs
$(GHC) -c -dynamic -fPIC Example.hs
wrapper.o: wrapper.c Example_stub.h
$(GHC) -c -dynamic -fPIC wrapper.c
clean:
rm -f *.hi *.o *_stub.[ch]
clean-all:
rm -f *.hi *.o *_stub.[ch] *.so
# Runs the example Python program
example: libffi-example.so
python program.py
The only thing wrapper.c does it creating wrappers for hs_init by calling hs_init(0,0);. The wrapper is called example_init
I get a segmentation fault when running make example, in example_init (ie when calling hs_init(0,0)).
Can someone tell me why this is and/or how to fix it?
Thanks!
It ought to work:
"Moreover, hs_init() may be called with NULL for both argc and argv, signalling the absence of command line arguments."
It seems to be a bug in ghc-7.2.1 to ghc-7.4.1:
RFib.hs:
{-# LANGUAGE ForeignFunctionInterface #-}

rfib.c:
#include <stdio.h>

Changing two lines in rfib.c:
int main(int argc, char *argv[]) {
hs_init(&argc,&argv);
it works with all versions (>= 7.0 that I have installed).
So to fix it
pass &argc and &argv
upgrade GHC
are the two most obvious ways.
