After using the 1-click Ubuntu installer, I'm having trouble figuring out how to import standard library functions for Phobos. I get the message:

Error: module io is in file 'std/std/io.d' which cannot be read
import path[0] = /usr/include/dmd/phobos
import path[1] = /usr/include/dmd/druntime/import

Sorry for such a basic question, but I am new to linux. Do I need to modify my path, or is Phobos just not located in the right directory?

Judging from the repeated stds up there I think you put a dot before io:

import std.std.io;  // <-- WRONG

The second dot should not be there. Do this instead:

import std.stdio;  // <-- correct

Thanks, I also found that I need to include the flag -I/usr/include/dmd/phobos to get it to compile. I tried doing:

export PATH=$PATH:/usr/include/dmd/phobos

but apparently I still need the -I flag. Is there another way to get around this?

You can use an IDE, that's what I did anyway

Does your /etc directory contain dmd.conf file? You can add standard flags there

Example of dmd.conf:

[Environment]
DFLAGS=-I/usr/include/dmd/phobos -I/usr/include/dmd/druntime/import

Yes, my dmd.conf file already has those paths.

PATH environment variable is not related at all with phobos2 sources paths.

All Linux packages (Ubuntu too) includes "-I/usr/include/dmd/phobos" on /etc/dmd.conf configuration file. If you need to explicit pass this argument to dmd compiler, may be due to several reasons.

- You've edited your "/etc/dmd.conf" file.

- You've created a new "dmd.conf" on your current directory, on you home directory or on dmd command directory (/usr/bin/).

Any "dmd.conf" file on these places, overrides "/etc/dmd.conf"

Take a look at:
$ cat /etc/dmd.conf

I didn't find any extra dmd.conf files, but I found that adding
#!/usr/include/dmd/phobos
to the top of my D program solved the problem to my satisfaction. Thanks so much for your help.

It really does seem like you have an extra dmd.conf that's being
loaded.

Type dmd -v abc.d - The first few lines should include what
config it's using.
