Compiling c code with root libraries

ROOT
3

Hi,

Thanks for your answer!
I don’t see how I can use different compilers when I want to use the root classes
inside the c programs. I will try however the updating option. So you suggest that
in C++ there is no need to use malloc at all? Or one needs to cast the pointer
that malloc returns using the correct type (e.g. float* )? Is this why it brakes?

The errors I get are too many to post them but here are the first few lines.
I should also probably mention the following two points that

  1. I have not compiled root from source but I
    used the binary:
    AMD64 Linux for Redhat RHEL 4 (SLC4) and gcc 3.4, version 5.20/00
    and I am using an
    AMD Opteron™ Processor 146

  2. I am including the root .h files with this option in the Makefile:
    -I$(shell root-config --cflags)
    Is this sufficient?

So when using CC=gcc I get
