[cfe-dev] Loading Static Analyzer plugin fails with CommandLine Errors

[Gábor Kozár]

(My apologies, I sent this e-mail first from the wrong e-mail account.)



I'm using Clang 3.3. I have a Clang Static Analyzer plugin that
contains the following symbols:



extern "C" const char clang_analyzerAPIVersionString[] =
CLANG_ANALYZER_API_VERSION_STRING;

extern "C" void clang_registerCheckers(clang::ento::CheckerRegistry&
registry)



However, when I try to do something with it, like:

clang++ -c test.cpp -Xclang -load -Xclang plugin.so



I get the following output:

<premain>: CommandLine Error: Argument 'view-background' defined more
than once!

<premain>: CommandLine Error: Argument 'debug-only' defined more than
once!

<premain>: CommandLine Error: Argument 'debug-buffer-size' defined more

I have never encountered such an error before, and this works perfectly
on a different machine, although with 32-bit binaries (it being a
32-bit system inside a VirtualBox).



The plugin was compiled using Clang 3.3, as a shared library, with
-fPIC and -fno-rtti. 'file plugin.so' output:

ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux),
dynamically linked, not stripped



'file clang' output:

ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically
linked (uses shared libs), for GNU/Linux 2.6.24,
BuildID[sha1]=0xb08840ba88f98740a0e3f4b6448e1c4b70ad57ce, not stripped



Clang (again, version 3.3) was configured with --enable-optimized, and
was built using GCC 4.7.2.



Any idea what could be the issue here?

Thanks!
