[cfe-dev] Trying to run clang example

[Sergey Martynov]

Hi all,

I'm trying to compile and run PrintFunctionNames example,
here is build file that I use:
-----------
#!/bin/bash

EXAMPLE=PrintFunctionNames

CLANG_MODULES=( AST Analysis Basic Checker CodeGen Driver Frontend
FrontendTool Index Lex Parse Rewrite Sema Serialization )
for mod in ${CLANG_MODULES[@]}
do
  CLANG_LIBS="-lclang$mod $CLANG_LIBS"
done

g++ `llvm-config --cxxflags` -c $EXAMPLE.cpp \
&&
g++ `llvm-config --ldflags --libs` $CLANG_LIBS -shared -o lib$EXAMPLE.dylib
$EXAMPLE.o

rm $EXAMPLE.o
-----------

But when I'm trying to execute clang with this plugin it crashes with
assert:
-----------
Assertion failed: (Inserted && "Pass registered multiple times!"), function
registerPass, file PassRegistry.cpp, line 101.

-----------

clang is compiled from svn:
clang version 2.9 (trunk 115408)
Target: x86_64-apple-darwin10
Thread model: posix

This example is working when I compile it using provided Makefile, so the
problem is in my build script.
But I don't want to use default Makefile because in this way plugin should
be located inside clang source tree.

Please advice me how can I resolve this issue.

Thank you.

With best wishes,
