Hi.

I'm a bit new to to D and Derelict and I was wondering if someone could point me in the right direction.

So far, I've installed dmd, build and built Derelict. Unfortunately, I'm a tad new to Linux as well and I have now idea what to do next, here's my current attempt:

* Copied Derelict sources to Phobos dir (/usr/phobos) and flattened them out according to a guide I found somwhere so that I can just do import derelict.sdl.sdl;

* Copied the .a files generated by buildme.d to /usr/lib

* Ran ldconfig

* Added -L-ldl to dmd.conf

Here's my problem:

* ldconfig didn't seem to pick up the Derelict libraries (i.e. ldconfig -p | grep derelict returns nothing). Do I have to convert the .a files to .so files somehow?

* A simple test program won't compile, like so:

My best guess is that your static libs are incomplete. Try putting derelict in some other place than dmd's dirs, then recompile it. IIRC, Build skips subdirectories of dmd, so your libs don't actually contain too much

You could also try another approach: http://dmedia.dprogramming.com/

Your code will be portable between platforms no matter how you set up dmd/build/Derelict. As long as it works and your import statements are standard then you're fine.

(Unless of course you use platform-specific code, then it won't be portable under any circumstances.)

Okay.

I followed the tutorial over at DMedia that h3r3tic suggested. You can see it here.
I changed some of the steps to fit my setup, here's what I did differently:

1. dmd and build is in /usr/bin where they should be
   
2. phobos is under /usr/d/src/phobos and derelict under /usr/d/src/ext/derelict
   
3. I added -I/usr/d/src/phobos & -L-ldl to /etc/dmd.conf
   

After doing this I attempted to compile the example program from the above tutorial like so:

Hmmm that's curious. It seems like gcc can't find symbols from the pthreads library... -L-lpthreads should fix it

[diepruis]

Thanks for the help guys.

@antz

I did as you said, rebuilt Derelict and put all the .a files in /usr/lib. Then I ran ldconfig, it still doesn't list the files. I didn't think it would though. I removed -L-ldl from dmd.conf and ran build.

No luck, it gave me the same error message as in my post above.


@h3r3tic

Before I tried your solution I deleted the Derelict libraries from /usr/lib, as your method on the site didn't mention copying them there.

Here's the result I got:

I'm not familiar with the syntax, but it seems to me like this would be more likely to work: -L-ldl -L-lpthreads

[h3r3tic]

... try -L-lpthread

ashley@monolith:~/temp/dertest$ build gl_test.d -I/usr/d/src/ext/ -L-ldl -L-lpthreads
/usr/bin/ld: cannot find -ldl-lpthreads
collect2: ld returned 1 exit status

@h3r3tic
ashley@monolith:~/temp/dertest$ build gl_test.d -I/usr/d/src/ext/ -L-l"dl pthread"
gcc: pthread: No such file or directory

Grrr..... Thanks for the help so far guys. Hope we can get this sorted out...

Why can't you just write it as I put it but try some weird -L-l"foo bar" instead ? o_0
