Hi Eric,
I'm getting a build error:
In file included from
/usr/local/google/home/tejohnson/llvm/llvm_16/tools/clang/lib/Tooling/Refactoring.cpp:21:
/usr/local/google/home/tejohnson/llvm/llvm_16/tools/clang/include/clang/Tooling/Refactoring.h:32:1:
error: class 'FormatStyle' was previously declared as a struct
[-Werror,-Wmismatched-tags]
class FormatStyle;
^
/usr/local/google/home/tejohnson/llvm/llvm_16/tools/clang/include/clang/Format/Format.h:43:8:
note: previous use is here
struct FormatStyle {
^
/usr/local/google/home/tejohnson/llvm/llvm_16/tools/clang/include/clang/Tooling/Refactoring.h:32:1:
note: did you mean struct here?
class FormatStyle;
^~~~~
struct
1 error generated.
ninja: build stopped: subcommand failed.
Looks like you added the "class FormatStyle" in Refactoring.h, looks like
this should be a struct instead.
Thanks,
Teresa
