[Dmitry Ermolov]

libclang1-3.4 is missing following functions, that exist in include files:
  - clang_CompileCommand_getNumMappedSources
  - clang_CompileCommand_getMappedSourcePath
  - clang_CompileCommand_getMappedSourceContent

how to reproduce:

 $ cat main.c
#include <clang-c/CXCompilationDatabase.h>

int main() {
    void* foo = &clang_CompileCommand_getNumMappedSources;
    void* bar = &clang_CompileCommand_getMappedSourcePath;
    void* baz = &clang_CompileCommand_getMappedSourceContent;
}
 $ gcc main.c -L/usr/lib/llvm-3.4/lib/ -I/usr/lib/llvm-3.4/include -l:libclang.so
/tmp/ccKnzo1E.o: In function `main':
main.c:(.text+0x8): undefined reference to `clang_CompileCommand_getNumMappedSources'
main.c:(.text+0x10): undefined reference to `clang_CompileCommand_getMappedSourcePath'
