[cfe-dev] Getting started with walking the AST

[Adam Smalin]

I had the idea that the missing headers may be somewhere in the build folder
and sure enough there they were.

I was able to build the wpa and PrintFunctionNames example. Looking in the
readme of PrintFunctionNames i saw

clang -cc1 -load ../../Debug+Asserts/lib/libPrintFunctionNames.so -plugin
print-fns some-input-file.c

so i ran
clang -cc1 -load clangPlugin.dll -plugin printfns a.c

and got
error: unable to find plugin 'print-fns'

I suspect it involves visual studios and exporting with its DLL. I included
the 'exports' file and it didnt help. It said "_ZN4llvm8Registry*" which is
weird. I suspect i am suppose to export
"FrontendPluginRegistry::Add<PrintFunctionNamesAction>". So i threw
__declspec(dllexport) in front of it which it complained about being static.
I remove static and it compile fine but i still get that unable to find
plugin error. If i use an incorrect dll file name it says it cant find the
module so i know the dll name is correct. I just dont know how to call
it/export it properly

Any ideas?

Also thanks for that edit retval, i'll want to run it but the problem above
prevents me from doing so.
