Bug ID: 32742
Summary: Clang manual should describe the include file search
Assignee: unassignedclangbugs at nondot.org
Reporter: guy at alum.mit.edu
CC: llvm-bugs at lists.llvm.org
I'm in the middle of trying to figure out why somebody's Wireshark build on
macOS fails with autotools and succeeds with CMake; it appears that it's not
finding header files in /usr/local/include with the autotools build but finding
them with the CMake build.
The CMake build is building with -isystem /usr/local/include, but the autotools
build isn't - but I can't find anything that would describe why adding it would
make a difference. The Clang manual at
doesn't appear to say very much about it.
The version of Clang they're using is
Apple LLVM version 8.1.0 (clang-802.0.42)
Thread model: posix
I have the same version on my machine, but my autotools builds work Just Fine,
finding the headers in /usr/local/include.
