Hi there, I've followed exactly the "how to install LDC" guide on the dlang.org download page. LLVM 3.7.1 is installed with target being x64. Then I've downloaded ldc and updated the submodules. Next step was the call to "cmake -DLIB_SUFFIX=64 .." in the build directory, followed by "make". This is the error message I get:

/home/username/Downloads/ldc/driver/linker.cpp: At global scope:
/home/username/Downloads/ldc/driver/linker.cpp:35:13: warning: ‘bool endsWith(const string&, const string&)’ defined but not used [-Wunused-function]
 static bool endsWith(const std::string &str, const std::string &end) {

make[2]: *** [CMakeFiles/LDCShared.dir/driver/linker.cpp.o] Fehler 1
make[1]: *** [CMakeFiles/LDCShared.dir/all] Fehler 2
make: *** [all] Fehler 2

Also, I've got DMD v2.071.0 installed.
Any suggestions how to resolve this?

Here's what I get when running make:

This is my fault I think. Looks like building master is broken for LLVM < 3.8. Working on a fix. Thanks a lot for reporting!

"LLVM < 3.8" Does that mean LLVM 3.8 should work properly?

Definitely.

Thanks! I'll give it a shot

It does work.
I still have to reconfigure and re-run since Mint can't seem to find the ldc executable after sudo installing llvm 3.8 (according to http://llvm.org/docs/CMake.html) and sudo installing ldc (according to http://wiki.dlang.org/Building_LDC_from_source)

I also fixed master for LLVM 3.7.

Good to know, but too late :D

Anyway, you might want to pardon this probably silly question: How do I invoke LDC? As I mentioned before I'd installed both LLVM and LDC via sudo make install. But no command I can think of and run will trigger LDC. ldc, lldc, lld, llvm-ldc or whatever won't work.

Sorry for the hassle – just in case anybody is wondering, this could only happen because our CI system is currently hamstrung by the LLVM APT repositories being temporarily offline.

The binary names are ldc2 for the "native" driver and ldmd2 for the DMD compatibility wrapper.
