Question

我正在尝试在Mac OS上编译gem5。我已经解决了到现在为止面临的3个问题，但是我停在了最后一个错误上。

错误提示：

有解决方案吗？

Answer 1

我找到了解决方法。

以下链接中的更改导致此错误：

https://gem5-review.googlesource.com/c/public/gem5/+/11518/

您可以还原“gem5/src/cpu/testesr/traffic-gen/SConscript”处SConscript文件中的更改，然后尝试进行协同编译。

我可以很好地编译并运行备用基准测试，并还原SConscript文件中的更改，如下所示：

    Import('*')


Source('base.cc')
Source('base_gen.cc')
Source('dram_gen.cc')
Source('dram_rot_gen.cc')
Source('exit_gen.cc')
Source('idle_gen.cc')
Source('linear_gen.cc')
Source('random_gen.cc')
Source('stream_gen.cc')

DebugFlag('TrafficGen')
SimObject('BaseTrafficGen.py')

#if env['USE_PYTHON']:
#   Source('pygen.cc', add_tags='python')
 #  SimObject('PyTrafficGen.py')

# Only build the traffic generator if we have support for protobuf as the
# tracing relies on it
if env['HAVE_PROTOBUF']:
   SimObject('TrafficGen.py')
   Source('trace_gen.cc')
   Source('traffic_gen.cc')

希望对于遇到相同错误的每个人都很好。

干杯，贝拉。
