[cfe-users] installing a complete clang++ environment

[Klaus Rudolph]

Thanks for your reply!

After several hours of trying I can't get it to work! :-(

I run into trouble with:


[ 98%] Built target lldb-platform
[ 98%] Building CXX object tools/extra/clang-apply-replacements/CMakeFiles/clangApplyReplacements.dir/lib/Tooling/ApplyReplacements.cpp.o
In file included from /home/krud/work/clang_complett_aus_source/src/tools/extra/clang-apply-replacements/lib/Tooling/ApplyReplacements.cpp:17:
/home/krud/work/clang_complett_aus_source/src/tools/extra/clang-apply-replacements/include/clang-apply-replacements/Tooling/ApplyReplacements.h:19:10: fatal error: 
      'clang/Tooling/Refactoring.h' file not found
#include "clang/Tooling/Refactoring.h"


Any hints?

Regards
 Klaus
