Ok, so I have been using build and I have been working perfectly fine, until
today, when I want to use DDoc and tried using

dmd -I.. -D test.d

I get,

Error 42: Symbol Undefined _D3jic4libs9MyLibTest10PrintHelloFZAa
--- errorlevel 1

source code is simple,

11:55:28.87>type test.d

private import jic.libs.MyLibTest;
int main(char[][] args)
{
PrintHello();
return 1;
}

and

11:58:08.13>type ..\jic\libs\MyLibTest.d
module jic.libs.MyLibTest;
char[] PrintHello()
{
printf("Hello\n");
}

I tried to see what options I could use, but somehow, the -I option for dmd is
not finding ..\jic\libs\.

Any ideas?

thanks.

Well, you're not linking this file in anywhere, as far as I can see.  You'll 
have to put either its source file or its object file on the command line.

You mean that I have to do,

dmd -D -I.. test.d ..\jic\libs\MyLibTest.d

Is this correct?  So, if I have 10 library files (..\jic\libs\MyLibTest0-9.d) I
have to add them all to the command?  I.e.

dmd -D -I.. test.d ..\jic\libs\MyLibTest0.d ..\jic\libs\MyLibTest1.d
.\jic\libs\MyLibTest2.d ..\jic\libs\MyLibTest3.d ..\jic\libs\MyLibTest4.d
.\jic\libs\MyLibTest5.d ..\jic\libs\MyLibTes6.d ..\jic\libs\MyLibTest7.d
.\jic\libs\MyLibTest8.d ..\jic\libs\MyLibTest9.d

If so, what does the -I option does then?  Sorry to be so unwise at this, but
build does all of that for me. :-)  And I have been using build since the Good
Lord brought me to D.

thanks for the help

If you use -I, you don't actually tell the compiler to import anything. 
  All you do is give it another directory from which it should look for 
imports.

For example, you can use -I"C:\verylongannoyingpathofevil\derelict\" so 
that you don't need to write it out for ever derelict module you use.

btw, I think Derek would love to hear that statement.  He's worked hard 
to make it easier to use D.

Or, just do this:

dmd -D -I"..\jib\libs\" test.d MyLibTest.d MyLibTest0.d MyLibTest1.d ...

Or, if you've already compiled those libs to .obj files,

dmd -D -I"..\jib\libs\" test.d MyLibTest.obj MyLibTest0.obj ...

All this does is compile the file 'test.d', it does not compile nor link
your library module. Try this instead ...

 
dmd -I.. test.d ..\jic\libs\MyLibTest.d

The dmd compiler is quite brain-dead when it comes to finding files. You
have to tell it everything.

Another way is to create a 'response file' for dmd.

---------- test.rsp ---------
-I..
test.d
..\jic\libs\MyLibTest.d
-----------------------------

Then use ...

dmd  test.rsp


Alternatively, just use 'Build' ;-)
