I've done

- git clone --recursive https://github.com/ldc-developers/ldc.git
- mkdir build
- cd build
- cmake ..

but it errors as

What's wrong?

Hi Nordlöw!

I don't have Ubuntu 14.04 at hand. Could you please post the output of

llvm-config --version
llvm-config --components

Thanks!

I have multiple llvm versions installed.

Could that be the problem?

I had the same problem.
1. in your case cmake picked up llvm version 3.5
2. cmake complains that it llvm-config-3.5 can't find profiledata component. I don't know why it is missing. I simply commented out the lines mentioning profiledata in cmake/Modules/FindLLVM.cmake

For me compilation still fails because llvm include file paths don't match the ones used in ldc source code.

Should I try removing some LLVM version?

It tries versioned names (e.g. with the -3.5 suffix) in descending order, so that seems to work like intended.

Where is your LLVM installation from? Distro packagages or how exactly did you build it?

>> For me compilation still fails because llvm include file paths don't match the ones used in ldc source code.

Could you elaborate a bit? The correct include paths should be picked up from the llvm-config output and added as command line arguments. If this doesn't work, there is either a bug in our CMake scripts or your LLVM installation is broken (we've had issues with broken distro packages before). The "paths" in the source code (really just llvm/) should be fine.

> Should I try removing some LLVM version?

In theory this should not be necessary, although it might certainly help to track down the problem.

Thanks,
David

I removed all but version 3.4 of LLVM and now it compiles all the till the end. Yay!
