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)
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.
Created attachment 1405887 [details] Patch for Fedora 28 LLDB package
Created attachment 1405888 [details] Patch for rawhide LLDB package
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.
