Hello,

I've tried to build this - it looks like a useful tool - but I've had some trouble. On Ubuntu 16.04 despite a successful apt-get install llvm-3.7-dev clang-3.7 libclang-3.7-dev I'm not able to make:-

mtandy@mtandy-desktop:~/Documents/elfs-clang-plugins$ make
g++  `llvm-config-64 --cxxflags` -O2 -g "enums_conversion/enums_conversion.cpp" -o "enums_conversion.o" -c -Wall -Wextra -Wno-unused -Wno-strict-aliasing -Werror
/bin/sh: 1: llvm-config-64: not found
enums_conversion/enums_conversion.cpp:3:51: fatal error: clang/Frontend/FrontendPluginRegistry.h: No such file or directory
compilation terminated.
Makefile:31: recipe for target 'enums_conversion.o' failed
make: *** [enums_conversion.o] Error 1

I can change the makefile to add -I /usr/lib/llvm-3.7/include/ to the g++ command - but that gives me hundreds of errors.

Presumably my environment is misconfigured. Do you think you could provide a travis buildfile or something similar, showing me how it's done?

Hi,

I have read your blog and your plugins, and It seems you don't use it. I cannot achieve what I want and maybe you know how to do it.

I am able to create a plugin FrontendPluginRegistry::Add that uses ASTConsumer and Visitor pattern, and modify the source code with Rewriter. The problem is that I cannot modify the source code that is compiled in that phase. I don't know how to affect the compilation itself. I tried with AddBeforeMainAction with no luck.

I only saw an option to overwrite source files, but it will modify the user files and it will need another run to compile the modifications. I just want to modify the files at runtime, in one step. I suppose it will need some sort of "after my plugin is executed, reparse again and run the whole compilation phase again".

I am executing the plugin like this clang++ ${FLAGS} -Xclang -load -Xclang ${path_to_so} -Xclang -add-plugin -Xclang $plugin_name -o $BIN ${FILE}.

The thing is that I need a plugin. I don't want to create an independent tool to do it (like libTooling with a main function).
