Re: Can't compile on Lion

Hi,

A similar issue was reported against the MacPorts version of root. See

https://trac.macports.org/ticket/30321

I guess the issue here is ROOT needs some work to be compatible with the llvm compiler, which is now the default in OS X 10.7 (compared to gcc 4.2 in SL) ? A work around with the MacPorts version is to use the gcc44 (or gcc45) variants of the port, which then build using macports gcc compilers.
