[Scons-dev] Show source SConscript on error

[Jason Kenny]

Let me clarify better.

We only really need this for the builder calls. Many cases nodes are made in the builders call themselves. For example

Env.Program(“Hello”,”hello.c”)

The node for hello.c does not exist until the Program builder function is called. Issues that exist are:

1) Program might call Object() under the covers. We want the Object builder to use the Program() location 
2) Some “builders” are just wrapper function to a number of builder calls.

We don’t need or I think want it for every node as we have lots of them also a node can be created in many different locations. The point of the node.fs object it act like a singleton manager to make sure when I say File(“#hello.c”) in different locations we point to the same one node. The only thing we have in Scons that does not like duplicates is the builder/action calls.

No only the builder

Likely that means every Node would have to be annotated with the source file and line it came from?
That could be quite memory intensive.

I think an example might be useful.
 
Given an error people like to see stuff like this: 
 
scons: *** [build\windows\README.txt] Source `README' not found, needed by target `build\windows\README.txt':
  File "C:\Some\source\location\Sconscript", line 3:
    Env.FooBuilder(“out”,[‘README.txt’])
 
 
Have an item on my list in Parts to muck up the Scons builder code to get this type of error message out… 
 
Better error messages in Scons would be a great thing 😊

I want SCons to show me the line in SConscript file where
this source 'README' dependency was defined.

Anatoly,
Not exactly sure what you would like SCons to do differently?
There's a message and a non-zero exit status.

Hi,
 
I was looking at this build log (see also below) https://ci.appveyor.com/project/YauhenMinsk/rhvoice/build/1.0.8
and noticed that there is no way to tell whan SConsript complains
about missing target. Do we have this info at all? If yes, why it is
not shown by default?
 
...
build\windows\packages\sapi\RHVoice-voice-Russian-Irina.nsi
scons: *** [build\windows\README.txt] Source `README' not found, needed by target `build\windows\README.txt'.
scons: building terminated because of errors.
Command exited with code 2
