digitalmars.D.learn - building a D app with multiple source files

reply "nikki" <nikkikoole gmail.com> writes:
Hello, I am completely new to D and have been paying around with
the tutorials, some docs and little test programs.

Now I want to try and use https://github.com/elvisxzhou/artemisd
for little gamedev experiment but I am running into build issues.
That project doesn't have a Makefile in the repo, and I am on
linux so I need to build it on the terminal,

I've read about rdmd (and tried it without success) and found a
few 'general' usage Makefiles, can't get any to just work when I
type 'make all'.

in the repo I linked to (artemisd) there are dozens of source
files in various folders, and an example i have to compile at the
same time I think.

could someone show me how it's done ?

What issues have you had with rdmd?

The library seems to have a package.json file, so you could also 
try dub:

The search path does not include the artemisd package.

Try: cd .. && rdmd artemisd/example/source/app.d
Or : rdmd -I.. example/source/app.d

You'll find it in dmd's --help. It adds the "source" directory to 
the search path, the list of directories where the compiler looks 
for imported modules.

edit: couldn't find that flag in dmd --help (only -Ipath), 
atleast I know what it does now, hope I'll remember..
thanks a lot though   great helpful community

The switch itself is -I, not -Ipath. 'path' indicates a parameter for 
which you need to substitute something, in this case a directory path. 
It should be the root folder for the source modules you want to add to 
the search path. In this case, for artemisd, the source files are in the 
'source' directory, so -Isource is what you pass to dmd. If the 
directory were named 'foo' instead, you would pass -Ifoo.

aha! that would've bitten me in the future, now I get it, thanks.

Remember rdmd is just a program to help collect and organise 
parameters. It still passes everything to dmd. In fact if you use 
the --chatty option with rdmd it will show you everything it is 
doing including what it is passing to dmd.

With rdmd, simply run `rdmd --build-only mainfile.d` (mainfile.d 
being the file that contains the "main" function). Omit 
--build-only to build the program to a temporary directory, then 
run it.

You can take a look at the dub build tool to automate all this 
(as mentioned above). Dub works by compiling and linking 
everything together in your source folder. You specify the main 
entry point in a dub.json file. It's pretty easy to use and good 
for handling dependencies over the internet.

To compile things manually you can use rdmd to automatically 
parse the files that need compiling. When using rdmd you only 
need to specify the file that contains the main function to build 
everything around it. for example:

rdmd program.d

This will pull in all imports inside program.d and compile and 
link them too.
