您不仅可以使编译器输出更短,还可以对其进行颜色编码,并添加详细标志。输出将如下所示:
替代文字 http://img526.imageshack.us/img526/9572/sconsf.png
方法如下(从 SCons Wiki 窃取的颜色主题):
import os,sys
colors = {}
colors['cyan'] = '\033[96m'
colors['purple'] = '\033[95m'
colors['blue'] = '\033[94m'
colors['green'] = '\033[92m'
colors['yellow'] = '\033[93m'
colors['red'] = '\033[91m'
colors['end'] = '\033[0m'
#If the output is not a terminal, remove the colors
if not sys.stdout.isatty():
for key, value in colors.iteritems():
colors[key] = ''
compile_source_message = '%s\nCompiling %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
compile_shared_source_message = '%s\nCompiling shared %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
link_program_message = '%s\nLinking Program %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
link_library_message = '%s\nLinking Static Library %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
ranlib_library_message = '%s\nRanlib Library %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
link_shared_library_message = '%s\nLinking Shared Library %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
java_compile_source_message = '%s\nCompiling %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
java_library_message = '%s\nCreating Java Archive %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
env = Environment()
AddOption("--verbose",action="store_true", dest="verbose_flag",default=False,help="verbose output")
if not GetOption("verbose_flag"):
env["CXXCOMSTR"] = compile_source_message,
env["CCCOMSTR"] = compile_source_message,
env["SHCCCOMSTR"] = compile_shared_source_message,
env["SHCXXCOMSTR"] = compile_shared_source_message,
env["ARCOMSTR"] = link_library_message,
env["RANLIBCOMSTR"] = ranlib_library_message,
env["SHLINKCOMSTR"] = link_shared_library_message,
env["LINKCOMSTR"] = link_program_message,
env["JARCOMSTR"] = java_library_message,
env["JAVACCOMSTR"] = java_compile_source_message,
使用“scons --verbose”编译以查看正常的大容量 gcc 输出。
