dlib doesn't build in either debug or release mode

Doesn't appear to build with an assertion failure

Debug Mode

echo dlib\coding\huffman.d >Debug\dlib.build.rsp
echo dlib\coding\package.d >>Debug\dlib.build.rsp
echo dlib\coding\varint.d >>Debug\dlib.build.rsp
...
ldc2 -m64 -gc -X -Xf="Debug\dlib.json" -deps="Debug\dlib.dep" -c -od="Debug" @debug\dlib.build.rsp -oq
if errorlevel 1 goto reportError

echo huffman.obj >Debug\dlib.build.lnkarg
echo package.obj >>Debug\dlib.build.lnkarg
...
ar cru "Debug\dlib.lib" @debug\dlib.build.lnkarg

fails with

Assertion failed: (*p == 'e' || *p == 'E') && "Invalid character in significand", file D:\Temp\LDC-BUILD\src\llvm-3.6.0.src\lib\Support\APFloat.cpp, line 272

Release Mode

echo dlib\coding\huffman.d >Release\dlib.build.rsp
echo dlib\coding\package.d >>Release\dlib.build.rsp
echo dlib\coding\varint.d >>Release\dlib.build.rsp
...
"H:\apps\VisualD\pipedmd.exe" ldc2 -lib -m64 -release -X -Xf="Release\dlib.json" -deps="Release\dlib.dep" -of="Release\dlib.lib" -L/MAP:"Release\dlib.map" @Release\dlib.build.rsp

** fails with **

Assertion failed: !(Pair.first != Ty && Pair.second == Ty) && "mapping to a source type", file D:\Temp\LDC-BUILD\src\llvm-3.6.0.src\lib\Linker\LinkModules.cpp, line 265

This fails before getting to the linking step unlike Debug mode

Found the file that doesn't work:-

dlib.geometry.ray.d:
struct Ray
{
Vector3f p0;
Vector3f p1;
float t;

// Commenting out this constructor seems to fix the problem
this(Vector3f begin = Vector3f(), Vector3f end = Vector3f())
{
p0 = begin;
p1 = end;
}
}

Which version and operating system do you use?
The first failure looks like you are using Windows. The problem is fixed in the current development trunk merge-2.067.
The second failure is #821 and #855 which is an LLVM bug.

I checked ldc2 0.15.1 on Linux that dlib can be build in debug mode.

[ronniec95]

Both errors on windows. OK will wait till milestone 0.15.2 release before checking again. Back to dmd on windows.

Latest dlib 0.10.1 can be built successfully with LDC 1.2-beta2 (both debug and release configs).
