+ Information about the cause of the build error: |
+ ----------------------------------------------- |
+ |
+ errstr : a description of the error message |
+ |
+ status : the return code of the action that caused the build |
+ error. Must be set to a non-zero value even if the |
+ build error is not due to an action returning a |
+ non-zero returned code. |
+ |
+ exitstatus : SCons exit status due to this build error. |
+ Must be nonzero unless due to an explicit Exit() |
+ call. Not always the same as status, since |
+ actions return a status code that should be |
+ respected, but SCons typically exits with 2 |
+ irrespective of the return value of the failed |
+ action. |
+ |
+ filename : The name of the file or directory that caused the |
+ build error. Set to None if no files are associated with |
+ this error. This might be different from the target |
+ being built. For example, failure to create the |
+ directory in which the target file will appear. It |
+ can be None if the error is not due to a particular |
+ filename. |
+ |
+ exc_info : Info about exception that caused the build |
+ error. Set to (None, None, None) if this build |
+ error is not due to an exception. |
+ |
+ |
+ Information about the cause of the location of the error: |
+ --------------------------------------------------------- |
+ |
+ node : the error occured while building this target node(s) |
+ |
+ executor : the executor that caused the build to fail (might |
+ be None if the build failures is not due to the |
+ executor failing) |
+ |
+ action : the action that caused the build to fail (might be |
+ None if the build failures is not due to the an |
+ action failure) |

+ command : the command line for the action that caused the |
+ build to fail (might be None if the build failures |
