Re: [Brahms-dev-l] brat compilation error

hi,

this is an old classic... at least when you are not using the same
version of the compiler as they do at brookhaven. Change the forward
declaration (class ostream;) on line 26 in the header file to #include
ostream. There is usage of an ostream operator in line 84 ... that should
fix it. I'm not completely sure if this is the best way to solve it, but I
guess so... newer versions of gcc are more strict than the old ones...

Cheers,
Truls
