Hi Manfred!

This is a problem with libconfig++. I can imagine 2 sources of 
errors here:

1) The path to libconfig++ on the cmake command line is wrong. 
This is the -DLIBCONFIG++_LIBRARY="..." parameter. Please note 
that the provided value is not checked by cmake.

2) It could also be a mismatch between static and dynamic 
compiled library. If you compile libconfig++ as DLL (the default) 
then you have to add -DLIBCONFIG_DLL=ON on the cmake command line.

I hope this helps.

The hope vanished midst of flight.
1) the path was set correctly.
2) the error count increased from nine to thirteen.

Ok, next try:

1) Regarding libconfig++: Did you create the x64 profile to 
compile for x64? Do you create a dynamic or static library? (BTW: 
I only tested linking against the static library.)

2) Regarding LDC: Could you please post your cmake commandline?

Did not do this twice and forgot to report on that. By that: I am on 
win8/64.

where can I find the documentation for creating such profiles---or do you 
really want to baby-sit me (... and all other babes out there)?

2)
The .bat file for ldc:

md build-ldc2-x64
git clone git://github.com/ldc-developers/ldc.git ldc
cd ldc
git submodule update --init
cd runtime\druntime
git checkout -b ldc-latest
cd ..\phobos
git checkout -b ldc-latest
cd ..\..\..\build-ldc2-x64
cmake -G "Visual Studio 10 Win64"
 -DCMAKE_INSTALL_PREFIX="C:/Program Files/LDC"
 -DLLVM_ROOT_DIR="C:/Program Files/LLVM-x64"  
 -DLIBCONFIG++_INCLUDE_DIR="C:/LDCenv/libconfig-1.4.9/lib"
 -DLIBCONFIG++_LIBRARY="C:/LDCenv/libconfig-1.4.9/Debug/libconfig++.lib"
 C:\LDCenv\ldc
msbuild ALL_BUILD.vcxproj
