LDC on Ubuntu 10.4
Hi,


I have just upgraded my Liniux box since I noticed that ldc came into 
Ubuntu packaging.

After downloading ldc and tango lib i can't compile anything that 
imports anything (so I guess it's a paths problem).


I want to complie this:


--------------------------
import tango.io.Stdout;

void main()
{
    Stdout ("hello").newline;
}

--------------------------

and I get this:
/usr/include/d/tango/core/Vararg.d(20): Error: module vararg cannot read 
file 'ldc/vararg.d'

After moving the missing 'ldc/vararg.d' file to appropriate folder (it's 
present in subdir) I get:

hi.o:(.rodata+0x0): undefined reference to `_D5tango2io6Stdout8__ModuleZ'
collect2: ld returned 1 exit status
Error: linking failed:
status: 1


Any ideas?
Maybe I ask somewhere else (ubuntu bug tracking)?

Cheers

I can't remember the source of these errors, you just need to play 
around a bit and it'll start working... Try adding -L-ltango-user-ldc to 
your build line, if ld can't find that it's called something else... If 
it is:

$ find /usr/lib -name '*tango*'

To get the name of the user library, and make sure you pass it to the 
linker (-L-llibnamehere, don't include the 'lib' or the '.a' though :)). 
Also make sure that the folder is in the linkers include path, using 
-L-L/usr/lib/d/ or whereever the ubuntu package stores the libraries.

You should also note that moving the ldc/ directory was not necessary, 
and, in fact, I advise against it. The correct solution is to add 
-I/usr/include/d/tango/core/runtime/compiler/ldc (or whatever the 
original path was) to your command line. If these things work, you can 
edit /etc/ldc.conf and add these switches in so you don't have to 
manually type them each time.

If neither of these works, try the ldc forums, the ldc mailing lists, 
the tango forums, the ldc irc channel on chat.freenode.net or the 
tango/D channels on the same network.

See the above list, if you manage to get it working you should report a 
bug to the ubuntu ldc packagers, as people seem to get this a lot with 
the ldc packages on ubuntu. They need to edit the ldc config file when 
the tango user library is installed I believe.
