[Scons-users] TryAction ('pkgconfig ..') and PRINT_CMD_LINE_FUNC => exception.

[Jos De Laender]

Dirk,

First of all, thanks for doing the effort. Appreciated.
For sure I'm willing to share it, it follows.

But it appears to me you missed an important piece of info : it actually 
doesn't matter how the PRINT_CMD_LINE_FUNC looks like,
except it shouldn't print to stdout. So a simple 'print 'Foo'' followed 
by return is sufficient to trigger the problem.

Actually , it looks like :

 >>> CODE
# Boilerplate to log commands nicely to screen and completely to log file.

def dlPrintCmdLine(s, target, src, env):

   # Always to a log file. (and with an extra linefeed to 'see' commands)
   LogFile = env['DL_LOGFILE']
   LogFile.write('\n%s\n'%s)

   ShortText = 'Building object'
   # 'Recognized' commands ?
   if 'DSCONS_CXX' in s:
     ShortText = dlGreen + 'Building CXX object'
   elif 'DSCONS_CC' in s:
     ShortText = dlGreen + 'Building C object'
   elif 'DSCONS_LINK' in s:
     ShortText = dlBoldMagenta + 'Linking'
   elif 'DSCONS_UIC' in s:
     ShortText = dlBoldBlue + 'Generating UIC object'
   elif 'DSCONS_MOC' in s:
     ShortText = dlBoldBlue + 'Generating MOC object'
   elif 'DSCONS_RCC' in s:
     ShortText = dlBoldBlue + 'Generating RCC object'
   else:
     # Install is a kind of exception. Also it points to a func.
     # We *assume* fallthrough is install. But that's a very shaky one.
     # XXX TODO
     ShortText = dlBoldMagenta + 'Installing'
   MyMessage = ''
   if not env['DL_VERBOSE']:
     MyMessage = ShortText + ' ' + ' and '.join([str(x) for x in target])
   else:
     MyMessage = s
   MyMessage += dlNoAttrs
   print MyMessage
   return None
 >>> END CODE
