Dear All,
I just found out that my root seems to be broken, for instance if I tried to run my code which was running without any problem by doing for instance:
root -l ttbar_abcd.root \\ which is a file containing a tree named myTree
myTree->Process("myDate.C")
I got this error:
fatal error: file '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/math.h' modified since it was first processed
Error in <TSelector::GetSelector>: The file myData.C does not define a class named myData.
Can someone tell me what’s the issue please ?
Thanks in advance,
cheers,
Diallo.
Hi ,
thanks for replying, actually I don’t remember to update something but by considering that could be the issue, I run it like that
myTree->Process("myData.C++")
and I still got the issue
Info in <TMacOSXSystem::ACLiC>: creating shared library /Users/dialloboye/Documents/Programming/abcd_method/ttbar/./myData_C.so

Hi,
You are right, this is related to my root system, actually I run it on lxplus and it works.
However I uninstall my root and install it again but I got the same issue. I was wondering maybe the way I uninstall root was not correct. Do you think that is enough to uninstall root just by removing all the directory ?
Cheers,
Diallo.
