Dear ROOTers, I have a trouble concerning a variable size two dimensional array. I defined a class A with a member 'int *aa[3]; //[n]'. (A mamber 'int n;' also included in the class A.) A shared library was construced successfully for the ROOT I/O. I could write or read a TTree in a TFile successfully with the shared library but could not draw a histogram with TTree::Draw("aa[][]") correctly in a ROOT interactive session. Please help me to solve the problem. By the way, I think it was useful if a syntax like 'int (*aa)[3];//[n]' was supported in rootcint. Is it possible? Best Regards, Hajime P.S. I used the ROOT at /afs/cern.ch/sw/root/v4.00.06/rh73_gcc32/root under Red Hat Linux 7.3 with gcc version 3.2. The simple code to illustrate the problem was attached. Files listed below was included in it. A.h,A.C,ALinkDef.h // for class A write.C // to write class A to TFile read.C // to read the TFile make.sh // make shell scrip run.C // for '.x run.C' in ROOT session The content of the file make.sh was as follows. ////////////////////////////////////////////////////////////// rootcint -f ADict.C -c A.h ALinkDef.h g++ -g --shared `root-config --cflags` `root-config --libs` \ -I. \ -o libData.so \ A.C ADict.C g++ -g -o write `root-config --cflags` `root-config --libs` \ write.C -L. -lData g++ -g -o read `root-config --cflags` `root-config --libs` \ read.C -L. -lData ////////////////////////////////////////////////////////////// Run as follows. source make.sh ./write test.root ./read test.root #--> succesfully operated ROOT [0] .x test.C #--> 'tree->Draw("aa[][]");' didn't work.
