Understanding Error Messages
In the days of FORTRAN code, the error messages generated by the
compiler, the linker and during execution were generally not too
difficult to understand. With the much richer C++ syntax,
auto-generated class dictionary code, shared libraries and dynamic
linking, it can be very hard to decipher some error messages. The
purpose of this section is to collect together the common problems
that people encounter. So if you hit a problem, take a look here.
Errors are classified according to what you were doing when the problem
Other useful sources of information about errors are:-
If all else fails. If things just don't work and you don't know why, try
the following in this order,and after each step, see if the problem is fixed.:-
- Errors while Compiling
i.e. when invoking the C++ compiler.
It does not include errors reported during execution by CINT.
- Warnings while Compiling
i.e. addition warning messages generated by the compiler,
that do not inhibit further code building but indicate
i.e. when linking to build an executable.
- Program Start
i.e. When starting to run a program.
i.e. during execution. It includes errors reported by CINT.
- Linux System Errors
i.e. errors reported by Linux.
- Log out and in again. This will clean up your environment.
- If you have a Test Release
This will help if the interfaces have changed in the Base Release.
In case SRT missed some dependency and failed to rebuild
something it should have done.
Let me know if you get stuck on a problem not covered here - we may at least
spare someone else the pain!
