Sudantha Unfortunately you cannot compile to an exe in WinHugs. As you suggested, it is indeed an interpreter. Sudantha: Please refrain from using text speak - that is ignorant and lazy English - remember - this is an English speaking forum, and international users are going to go "WTF" is that and what does it mean - some may not have the same English language skill as their native English speaking counterparts.
Take this on board and remember it! Sudantha - well refrain from text speak and use proper English, we can help and will understand Show 1 more comment. Active Oldest Votes. By default it compiles to executables, and it works the same on Linux or Windows. Improve this answer. The application of l with l is the standard syntax for visible type application see Visible type application.
This syntax is not currently exposed to the programmer, but it is nevertheless displayed when -fprint-explicit-kinds is enabled. Using -fprint-explicit-coercions makes GHC print coercions in types. When trying to prove the equality between types of different kinds, GHC uses type-level coercions. Users will rarely need to see these, as they are meant to be internal. The equations are numbered starting from 0, and the comment after each equation refers to all preceding equations it is incompatible with.
Using -fprint-equality-relations tells GHC to distinguish between its equality relations when printing. See also Equality constraints. When enabled, GHC also prints type-synonym-expanded types in type errors. For example, with this type synonyms:. Causes GHC to group diagnostic messages by severity and output them after other messages when building a multi-module Haskell program. Otherwise, it can be hard to find the relevant errors or likely to ignore the warnings when they are mixed with many other messages.
Causes GHC to display error messages with colors. To do this, the terminal must have support for ANSI color codes, or else garbled text will appear. The default value is auto , which means GHC will make an attempt to detect whether terminal supports colors and choose accordingly. These are the default settings:. The formatting of each element can inherit from parent elements.
For example, if header is left empty, it will inherit the formatting of message. Alternatively if header is set to 1 bold , it will be bolded but still inherits the color of message. In the caret diagnostics, there is currently no inheritance at all between margin , warning , error , and fatal. The environment variable can also be set to the magical values never or always , which is equivalent to setting the corresponding -fdiagnostics-color flag but with lower precedence.
Controls whether GHC displays a line of the original source code where the error was detected. This also affects the associated caret symbol that points at the region of code at fault. The flag is on by default. Causes GHC to emit the full source span of the syntactic entity relating to an error message. Normally, GHC emits the source location of the start of the syntactic entity only. Note that line numbers start counting at one, but column numbers start at zero. This choice was made to follow existing convention i.
Causes GHC to continue the compilation if a module has an error. Any reverse dependencies are pruned immediately and the whole compilation is still flagged as an error. Causes GHC to output errors in reverse line-number order, so that the errors and warnings that originate later in the file are displayed first.
Prints a one-line summary of timing statistics for the GHC run. Enabling this flag has no effect and is only present for future extensions. Since GHC 8. Even when setting this flag, SSE2 will be used instead. This gives a substantial performance improvement for floating point, but the resulting compiled code will only run on processors that support SSE2 Intel Pentium 4 and later, or AMD Athlon 64 and later.
The resulting compiled code will only run on processors that support SSE4. Note that the current version does not use BMI specific instructions, so using this flag has no effect. By default, GHC ignores Haddock comments With this flag GHC will parse Haddock comments and include them in the interface file it produces. The compiler will lookup the path for the ghcversion.
This option can be used to specify the path to the ghcversions. GHC can also be configured using environment variables. Glasgow Haskell Compiler 9. Introduction 2. Release notes 3. Using GHCi 4.

Someone responded to my question, suggesting I open the command line and put ghc --make helloworld and hit Enter.
However, when I put in ghc --make helloworld and hit Enter this comes up:. The person answering the question suggested I made another question, asking why I received the above message. How can I deal with this problem?
Yes, it is possible to use Windows to compile Haskell programs. In fact, I use Windows for all my Haskell programming! Note that there is no space between -- and make ; including this space gives the error you describe. After running this command, an executable helloworld.
