Hi Knud,

either you don't have the libconfig++ library installed or cmake 
can't autodetect it. In the latter case you can tell cmake the 
path with --DLIBCONFIG++_INCLUDE_DIR=... and 
-DLIBCONFIG++_LIBRARY=...

Regards
Kai

BTW: I tried to reply to your mail but received an "account 
expired" error.

Unfortunately, LDC from current Git master does not build on Linux/ARM yet.

If you are interested in working on getting this done, I can provide
you with the last working (as far as a Phobos "Hello World" is
concerned) version. I tried to commit them some while ago, but then
getting the release out was more important. Hopefully, I'll be able to
finally push the changes in the next few days,

Could you please post the output of "ldc2 -version" and "ldc2 -vv

Compiling druntime/Phobos and a Hello World program works for me
(although EH is still not implemented properly).

I installed llvm 3.4 and is now making.

But I noticed cmake says:
Found LLVM: /usr/lib/llvm-3.4 (found suitable version "3.4", minimum
required is "3.1")

Maybe the minimum cmake accept should be raised.

That is a bit strange. The only issue with LLVM 3.4 I am aware of 
is that you should enable assertions on LLVM or define NDEBUG 
while building ldc. Otherwise you get a link error while linking 
ldc2.

Could you please some more information about your environment? 
gcc (or clang) version and glibc version could be helpful.

Thanks for trying this!

Yes, indeed, especially since the Travis 3.4 build is green:
https://travis-ci.org/ldc-developers/ldc Maybe either the version Knud
is using or the snapshot Travis is pulling in is out of date?

 The only issue with LLVM 3.4 I am aware of is that
 you should enable assertions on LLVM or define NDEBUG while building ldc.
 Otherwise you get a link error while linking ldc2.

Wasn't that also the same for at least some of the previous versions as wel=
l?

No. This is a LLVM "optimization" introduced during 3.4 
development. I was  building LLVM on Linux/PPC64 on a weekly 
base, always starting with a fresh image and using the same 
script. Suddenly, it stopped working because of this.

 But I noticed cmake says:

 Maybe the minimum cmake accept should be raised.

Hi Knud!

That is really difficult as each architecture has a different 
state. You can use LLVM 3.1 with LDC if you are targeting 
x86/x86_64. Other targets are less mature and may require newer 
versions of LLVM. E.g. PPC64 requires at least LLVM 3.3, PPC32 at 
least LLVM 3.4.

Hi

YES, I was successful building ldc on raspberry pi with LLVM 3.3.

 You need at least LLVM 3.3 to hope that things work. I thought this
 was mentioned on the Wiki page, but apparently it wasn't – added it.

If you'd like to help out with getting LDC to work properly on ARM,
you might be interested in the tentative druntime patch fixing the
libunwind interface I just posted to GitHub:
https://github.com/ldc-developers/ldc/issues/489.
