Try doing something like:

dmd main.d omat/rin.d

(or omat/rin.d = wherever your rin.d file is)

```
```Or use,

build main.d

```now i changed 1 line of rini.d (module file) as module omat.rin and executed command "dmd rini.d" because i don't have main.d at all. Still i got same error message.

Then i tried this kind of solution. I copied omat directory with rin.d to same directory where rini.d is located. then i remobed i line so it isn't module anymore. i changet 1 line of rini.d (what you called as main.d) to "#include <c:\dc\omat\omat\rin.d>". My rini (main) is located at c:\dc\omat\. After all this i ran again "dmd rini.d" (main). Now i got a bit differend error message. It goes like this:
rini.d(1): #line integer ["filespec"]\n expected
rini.d(1): Declaration expected, not '<'
rini.d(1): undefined escape sequence \d

rini.d(1): undefined escape sequence \o

```and another thing. i don't have build command. like i said iäm using windows and notepad as editor. could it be that notepad puts that kind of end to file what d compiler doesn't understand?

```1. There's no '#include' in D
2. You can get the 'build' utility from here: http://dsource.org/projects/build/
3. Without 'build', you have to pass all of your files to dmd, so "dmd rini.d" won't do. You might try "dmd rini.d omat\rin.d" (or whatever paths you have there)
4. Notepad's not the best editor... Actually it's one of the worst when it comes to programming. Check this out: http://www.wikiservice.at/d/wiki.cgi?EditorSupport
/* my current favourite is the Elephant IDE */
5. Excellent resource: http://dsource.org/tutorials/

You can get the very useful Build utility here:
http://dsource.org/projects/build/

And you might double-check that Notepad isn't putting a .txt on the ends of your filenames.  Generally its better to find a coding editor, such as EditPlus or ConTEXT, rather than stick with Notepad.  (Although for many moons I did all my HTML, PHP, Java, and C code in Notepad... but I don't dare say I'd want to go back.)

You may have already gotten this to work, but in case someone else runs into a problem like this I thought I'd explain a fix.

I've set up three files (which are attached): rin.d, rini.d, and rin.bat. All three are put into a folder called "omat". Run "rin.bat" to compile and run the program. I moved some punctuation around, but the only significant change that I made to your files was adding "module omat.rin;" to the top of rin.d.

(By the way, this error message is also described at http://www.prowiki.org/wiki4d/wiki.cgi?ErrorMessages#Error42SymbolUndefined.)

This is what is looks like when I run "rin.bat":
----------------------------------------------------------------
I:\pgm\d\examples\linker_error_msg\omat>dmd rini.d rin.d -I.. d:\dmd\bin\..\..\dm\bin\link.exe rini+rin,,,user32+kernel32/noi;

I:\pgm\d\examples\linker_error_msg\omat>rini.exe

0.800000
I:\pgm\d\examples\linker_error_msg\omat>pause
