Strange error when reading vector<int>

ROOT

Dear rooters,

With the attached files I’m having the following compilation warnings

[size=85]Dict.cc:258:10: warning: ‘const’ qualifier on reference type ‘vector<int, allocator >::reference’ (aka ‘int &’) has no effect [-Wignored-qualifiers]

and run time error;

[size=85]Error in TTree::SetBranchAddress: Unable to determine the type given for the address for “mc_pdgId”. This is probably due to a missing dictionary, the original data class for this branch is vector.

*** Break *** segmentation violation
Generating stack trace…
0x0000000000000001 in [/size]

This is sort of strange because I do exactly the same, in order to read vector variables and having no error with them. Only with int vectors.

Any help would be appreciated.

Best,
Bora

“./input_file.root” is missing.
btw. which root version, on which system and with which compiler are you using?
p.s. your “clean” target is missing “rm -f Dict*”

Hi,

input file is too large to attach but I can assure you that the variable type is vector.

I use ROOT 5.34/14 on OS X Yosemite 10.10.5 with Xcode 6.4.

Best,
Bora

Try 5.34/32 (or maybe even better the head of the v5-34-00-patches branch) or/and 6.05/02.

I’m not really sure if it helps but try to add, right in the beginning of your main:
TApplication a(“a”, 0, 0);

Hi. It works with 6.04/02. Thank you!
