[Scons-users] command-line call without error

[Rob Deckers]

Hi all.
In my AStyle tool for SCons, I do a command line call to AStyle.
When AStyle failes, I would like to log a warning, NO error and not stop the build.
Currently, I have :
      # create the style command
      cmd = "${STYLEEXE} %s ${STYLEFLAGS} ${_STYLEEXCLUDEFLAGS}" % filestostyle

      # Warn about the failure, but do not fail the build when Style fails.
      if env.Execute(cmd):
          SCons.Warnings.warn(ToolStyleWarning, "code styler tool: '%s' failed!" % (env['STYLEEXE']))
This almost works, I do not stop the build, log a warning, but ALSO an error when AStyle failes.
According to the SCons manual, this is behavior of env.Execute:
"Note that scons will print an error message if the executed action fails--that is, exits with or returns a non-zero value."
How do I NOT print an error when my command line call failes?
Best regards,
Rob
