In general, SCons tries to keep its error messages short and informative. That means we usually try to avoid showing the stack traces that are familiar to experienced Python programmers, since they usually contain much more information than is useful to most people.
For example, the following
Generates the following error if the
does not exist:
scons -Qscons: *** [prog.o] Source `prog.c' not found, needed by target `prog.o'.
In this case,
the error is pretty obvious.
But if it weren't,
and you wanted to try to get more information
about the error,
would show you exactly where in the SCons source code
the problem occurs:
scons -Q --debug=stacktracescons: *** [prog.o] Source `prog.c' not found, needed by target `prog.o'. scons: internal stack trace: File "bootstrap/src/engine/SCons/Job.py", line 199, in start task.prepare() File "bootstrap/src/engine/SCons/Script/Main.py", line 177, in prepare return SCons.Taskmaster.OutOfDateTask.prepare(self) File "bootstrap/src/engine/SCons/Taskmaster.py", line 198, in prepare executor.prepare() File "bootstrap/src/engine/SCons/Executor.py", line 430, in prepare raise SCons.Errors.StopError(msg % (s, self.batches.targets))
Of course, if you do need to dive into the SCons source code, we'd like to know if, or how, the error messages or troubleshooting options could have been improved to avoid that. Not everyone has the necessary time or Python skill to dive into the source code, and we'd like to improve SCons for those people as well...
