Hi Mathieu,
I would prefer that you make the diff against the svn trunk using the “svn diff” command. The diffs you sent me do not work straight forward. I agree I can modify the files using your diffs but using the svn diff command has also the advantage that we are sure there is no mistmatches of versions.
For info I get:
$ cd $ROOTSYS
$ patch -p0 --posix < /Users/couet/Downloads/TGraph.cxx.diff
can't find file to patch at input line 1
