Has anyone been able to build LDC from source?  I tried configuring the
CMake stuff but the resulting Make system simply does nothing =E2=80=93 but=
 it
does it very quickly :-)

Thanks.

Do you get any CMake error messages? Just running cmake/ccmake in 
the root directory should be quite well-tested on various Linux 
distros, OS X, and Windows, so I'm somewhat surprised to hear 
that…

 You probably didn't do

 git submodule init; git submodule update



Or in one command:

$ git submodule update --init

You can also add --recursive to be on the safe side.

BTW I've added pointers for the LDC instructions to the download page:

the -2 is not necessary; also this doesn't install phobos or druntime.

yum install ldc ldc-phobos-devel ldc-druntime-devel

should bring in everything necessary for compiling.

Initial problem appears to be that there is no clean target despite the
dopcumentation. Then I found I didn't have libconfig++ installed but the
build wasn't telling me that. Now I actually get some activity, but no
clean. ldc2 builds to 43MB of file, but then the build fails for some
reason to do with not finding druntime.

Builds really should work out of the box :-(

You probably didn't do

git submodule init; git submodule update

So it doesn't find druntime because there is no druntime :D. 
There are build instructions on the LDC github wiki that always 
worked for me on Debian Wheezy.

Any idea why -j9? It seems very specific and is only really going to

I don't know, but I assume that whoever wrote the instructions 
was using a machine with 8 cores. Using n + 1 (where n is the 
number of cores) threads with make is supposed to be faster than 
using n threads. At least that's what people say. I have only 
tested this once and it turned out to be true in that case but 
that hardly proves it.

Thanks for this "heads up", worked a treat.

Moral of story: LDC developers should change the readme.txt pointing
people explicitly at the wrong place to find the right build
instructions.

Better add links to

As long as LDC continues to track the current D version, I am sold on
it. No statistically significant numbers yet but indications are that
LDC produces faster code than DMD on Debian Unstable running on my twin
Xeon.
