Hello
I’ve just recompiled the head of the v5-34-00-patches branch with gcc6 (gcc version 6.2.0 20161005 Ubuntu 16.10) and, although the build succeeds, I got a lot of warnings about misleading indentation:
/home/john/software/sources/root/build-v5-34-00-patches/include/TMatrixTSym.h: In member function virtual void TMatrixTSym::Clear(Option_t*):
/home/john/software/sources/root/build-v5-34-00-patches/include/TMatrixTSym.h:97:60: warning: this else clause does not guard… [-Wmisleading-indentation]
else fElements = 0; this->fNelems = 0; }
^~~~
/home/john/software/sources/root/build-v5-34-00-patches/include/TMatrixTSym.h:97:80: note: …this statement, but the latter is misleadingly indented as if it is guarded by the else
else fElements = 0; this->fNelems = 0; }
^~~~
What is the status of ROOT vs. gcc6? I know already that gcc5 cannot be used to compile ROOT6 (I use clang - is this still valid?) Is gcc6 an improvement on gcc5?
Thanks a lot
John
