Dear all,
I am trying to compile a C++ program calling root libraries. In the past it compiled with no problem, but now I have a more recent ubuntu version (15.10) and a more recent root version (6.06/00) and when I run the makefile, I get:
test.c:290:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
/usr/bin/gcc root-config --glibs -lm -nostartfiles -g test.o -o test
/usr/bin/ld: warning: cannot find entry symbol _start; defaulting to 0000000000401a70

In attachment are my C++ program and my Makefile.
Could anyone tell me how to change my Makefile, please?
