I have a file called HttpCommon.d where I am throwing code that needs to be imported by a few files in my project. It contains an enum and a few constants. When I try to to import it, I get the following error:

Request.d:5: module HttpCommmon cannot read file 'HttpCommmon.d'

HttpCommon.d (in the same directory) contains:

//Common globals for HTTP

enum Protocol   {
        //Removed
}

static char[] getProtocolName(Protocol protocol)        {
        //Removed
}

static Protocol getProtocolByName(char[] name)  {
        //Removed
}

class StatusCode        {
        //Removed
}

What's going on? I don't understand how the compiler finds files, but I'm thinking that's where it's going wrong.

There is a restriction in D in that one cannot have a module with the same name as the directory it appears in. The simple workaround is to rename one or the other.

hmmm, maybe I am misunderstanding, but the directory these files are in is called "dhttp" (I'm on linux, so the path is really just ~/dhttp). The file structure looks like this:

dhttp
        Request.d
        HttpCommon.d
        [other d files]
        Makefile

Does HttpCommon need to be in a subdirectory? I admit I find all this a little confusing, Java handles things a little differently.

You get this message if you haven't passed a file to the compiler.

dmd HttpCommon.d

andymadigan@andym:~/dhttp$ gdc -c Request.d HttpCommon.d Request.d:5: module HttpCommmon cannot read file 'HttpCommmon.d'

Note that HttpCommon.d does build fine.

I have actually done almost this exactly same thing... multiple times.  You have three 'm's in HttpCommmon in Request.d line 5.

Sorry, it was my misunderstanding (I rushed a reply as I was going out to see my football team play - they lost).

Have you tried the Build utility? It would avoid spelling mistakes like this.

Wow, I need to stop making dumb posts to this forum, I must have looked at that same line of code 50 times.

Allright, now I'm getting a related error, there are two functions defined in HttpCommon.d (they're global). I'm getting errors about multiple definition. What should I do?

It seems like you're compiling both HttpCommon.d and HttpCommon.o, and that they're conflicting with each other.
