Description Omair Majid 2018-02-24 20:43:09 UTC 
There is a missing LLDB.h file in lldb-devel package. This is the entry point for all LLDB-API using code so various programs fail to compile because of this.

On Fedora 27:

$ rpm -q lldb-devel
lldb-devel-5.0.1-1.fc27.x86_64
$ rpm -ql lldb-devel | grep LLDB.h
/usr/include/lldb/API/LLDB.h

On Fedora 28 (or rawhide, this is a bit bastardized system):

$ rpm -q lldb-devel    
lldb-devel-6.0.0-0.3.rc2.fc28.x86_64  
$ rpm -ql lldb-devel | grep LLDB.h

The header is present in fedora sources:

$ fedpkg  clone -a lldb
$ cd lldb
$ fedpkg prep
$ git rev-parse HEAD
3496185f17b8bf0ed623856dd026ead53fc34e5c
$ find -iname 'LLDB.h'
./lldb-6.0.0rc2.src/include/lldb/API/LLDB.h

But is not installed?

An example of a failure is seen on copr here: https://copr-be.cloud.fedoraproject.org/results/@dotnet-sig/dotnet/fedora-28-x86_64/00720374-dotnet/build.log.gz:

  CMake Error at src/ToolBox/SOS/lldbplugin/CMakeLists.txt:87 (message):
    Cannot find LLDB.h.  Try installing lldb-3.6-dev (or the appropriate
    package for your platform)
Comment 1 Tilmann Scheller 2018-03-07 14:40:53 UTC 
Looks like this is broken since r309021 including the trunk snapshot of today. This means it also affects LLVM 6.0.

I've filed https://bugs.llvm.org/show_bug.cgi?id=36630 to get this fixed upstream.

The change that introduced the regression is easy to revert so I hope to have the Fedora LLDB package fixed soon.

Comment 4 Tilmann Scheller 2018-03-08 15:43:22 UTC 
Attached patches for Fedora 28 and rawhide. Verified them with Mock builds, with the patches applied the headers are included in the lldb-devel package again.

I don't have write access to the Fedora LLDB package yet but Tom should be able to apply them soon.
