@layus well I just rm -rf my old directory, cower -d mozart2-git and it gets back. Breaking API for the sake of it on each release tsss...Thx :)

@mayweed This is probably due to a new version of LLVM/Clang. They tend to break their internal API on each new release. The simplest fix would be to use an older version. Upstream (= mainly me) is working on releasing preprocessed sources that do not require LLVM/Clang... To be continued :-).

@layus it works indeed til today where I got an error in Emacs (code 127 ozemulator), I tried to rebuild it and:

I try to add LLVMSupport, LLVMSystem etc...to no avail. If you got an idea...

Updated to ignore VM tests for now.

@mayweed: this is a transient problem. There is apparently a bug in the implementation of VMs, which is a new, undocumented feature. A you will probably not use these, you can safely ignore it. See https://github.com/mozart/mozart2/issues/284 for extra info.

Hmm... I am trying to reproduce this locally. Could you re-run the tests with `makepkg [-eo] --check` ? (I do not know if -eo is required or not.)

Just try to install it today and:

96% tests passed, 1 tests failed out of 23

Total Test time (real) = 40.66 sec

The following tests FAILED:
12 - /base/vm.oz (Failed)
Errors while running CTest
make: *** [Makefile:84: test] Error 8
==> ERROR: A failure occurred in check().
Aborting...

It does, yes. This is because of an upstream update made yesterday afternoon. I will updade this package an clang altogether. In the meantime you van still edit the PKGBUILD to add it.

The PKGBUILD seems to be missing a dependency -- if I don't have `clang-tools-extra` installed, I get this error:

```
-- Found LLVM 3.8.1
-- Using LLVMConfig.cmake in: /usr/share/llvm/cmake
CMake Error at /usr/share/clang/cmake/ClangTargets.cmake:330 (message):
The imported target "clangApplyReplacements" references the file

"/usr/lib/libclangApplyReplacements.a"
```

Could you add some details? Do you get the error during build, or during execution. Are you sure to build with --cleanbuild ? What is the exact error you get ? I am totally unable to reproduce this behavior.
