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… David

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.

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.

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.

Better add links to https://github.com/ldc-developers/ldc/wiki/Installation for building on Linux and https://github.com/ldc-developers/ldc/wiki/Building-and-hacking-LDC-on-Windows-using-MSVC for building on Windows. Jens

As long as LDC continues to track the current D version, I am sold on it.
