Re: Compile error with gcc 4.4.0

Hi Johan,

there is no official release of GCC 4.4 yet, so whatever Red Hat released is their home grown thing. And apparently it has a bug, or there is an issue with the setup. As a hint: I have the requested symbol in lib/libRIO.so; it's generated (as a weak symbol) from io/io/src/TStreamerInfoReadBuffer.cxx, both the function definition and the template instantiation happen in there, so it's also in io/io/src/TStreamerInfoReadBuffer.o.

Cheers, Axel.
