I'm with gdc on linux, And think I dont understand how
files/packages/modules works.
I am organizing files in folders like this:

/main/something/moda.d
/main/gui/modb.d

in modb.d: Can I import moda?
I get "module modb cannot read file..."

Thanks and sorry for my strange english!

If you tell DMD that your import path is the 'root' the one which contains 'main' then in /main/something/moda.d you could write "import main.gui.modb;". Likewise, in /main/gui/modb.d you would write "import main.something.moda;".

The import package/module/file is relative to the import path root(s). The file sc.ini in dmd/bin/ tells it where the import path root(s) are, eg:

DFLAGS="-I%@P%\..\src\phobos;%@P%\..\..\src"

The -I is for import paths, note that I have added %@P%\..\..\src (I'm on windows), this is my import path root for most of my D source code. %@P% resolves to the dmd/bin directory.

The module and package names in an import statement are *not* relative to
the file importing them. This is a common misunderstanding so don't worry.
Instead, there are relative to "import paths". An import path is a starting
place to scan for modules. The import paths can be specified in two
places:-
 (1) The command line switch "-I". You can have any number of these and
they specify an import path. E.G. -I/main/something -I/main/gui

 (2) The file "dmd.conf" (for Linux) which can be in ...
     -> current working directory
     -> directory specified by the HOME environment variable
     -> directory dmd resides in
     -> /etc/
  contains a line similar to

    DFLAGS="-I%@P%/../src/phobos"
  You can extend this line with other default import paths, but watch out
when installing new versions of DMD as your changes are overwritten.

I'm not sure that GDC supports the dmd.conf file idea so you may have to supply all import paths on the command line.

Anyhow, if you source file contains...
  import moda;

then you need an import path for "/main/something" so that the compiler can find it.

Likewise if the import statement say "import something.moda;" then the import path should be "/main" and the module statement in moda.d should be "module something.moda;"

Looks pretty good to me.

Perfect! Thanks!
Anyone knows how can I set the import path root using gdc? It has no
sc.ini file.

Ok, that's what i'll do.

Thanks for your help!
