Initialization of dragonegg plugin failed

[Manuel]

Binary package hint: dragonegg

When I try to compile a file, the initialization of the dragonegg plugin fails:

$ echo "int main() { return 0; }" > /tmp/test.cpp
$ llvm-g++ /tmp/test.cpp
Incompatible plugin version
cc1plus: error: Fail to initialize plugin /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5/plugin/dragonegg.so

but g++-4.5 is used, as you can see in the verbose mode:
$ llvm-g++ /tmp/test.cpp -v

Description: Ubuntu 11.04
Release: 11.04

dragonegg-2.8-0ubuntu2
llvm-gcc-2.8-0ubuntu2

[Terry Wilson (otherwiseguy)]

This bug is fixed by the Debian dragonegg-2.8-3 package as described here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618768

This bug makes the package completely unusable for compiling.

[Manuel (manuel-schoelling)]

Yes, but it depends on gcc-4.5.3. The current version of gcc in Ubuntu is gcc-4.5.2.

Probably we have to wait for Ubuntu to update gcc.

[Wu Jiang (jiang)]

As it was said here http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618768, use
$ dragonegg_disable_version_check=1 llvm-g++ /tmp/test.cpp
for now.

Fixed by version 2.8-3
