Bug#909463: ITP: flang -- Fortran compiler using the LLVM toolkit

[Alastair McKinstry]

Hi Sylvestre,

I've been looking at 'f18' which appears to be the next evolution of 
'flang'

https://github.com/flang-compiler/f18

It appears building the front-end would be easier, but I've been testing 
against llvm-7-dev (installed), and get:

    cmake ..
    -- The CXX compiler identification is GNU 8.2.0
    -- Check for working CXX compiler: /usr/bin/c++
    -- Check for working CXX compiler: /usr/bin/c++ -- works
    -- Detecting CXX compiler ABI info
    -- Detecting CXX compiler ABI info - done
    -- Detecting CXX compile features
    -- Detecting CXX compile features - done
    -- Build Type: Debug
    CMake Error at
    /usr/lib/llvm-7/lib/cmake/clang/ClangTargets.cmake:544 (message):
       The imported target "clangBasic" references the file

          "/usr/lib/llvm-7/lib/libclangBasic.a"

       but this file does not exist.  Possible reasons include:

       * The file was deleted, renamed, or moved to another location.

       * An install or uninstall procedure did not complete successfully.

       * The installation package was faulty and contained

          "/usr/lib/llvm-7/lib/cmake/clang/ClangTargets.cmake"

       but not all the files it references.

    Call Stack (most recent call first):
       /usr/lib/cmake/clang-7/ClangConfig.cmake:19 (include)
       CMakeLists.txt:42 (find_package)


Is libclangBasic.a to be expected on eg. amd64? According to 
packages.debian.org, it's present in


	libclang-7-dev <https://packages.debian.org/sid/libclang-7-dev> 
[powerpcspe, sparc64, x32, ppc64]

Any ideas?

regards

Alastair
