Hello all,
I'm encountering a somewhat strange issue with the latest gem5 master. In a
fresh build directory, I can build either gem5.opt or libgem5_opt.so, but not
one after the other. That is, when I run:
rm -rf build
scons -j32 --without-python --with-cxx-config build/ARM/libgem5_opt.so
Everything compiles fine. However, when I run:
rm -rf build
scons -j32 build/ARM/gem5.opt
scons -j32 --without-python --with-cxx-config build/ARM/libgem5_opt.so
Then I get this error:
scons: Building targets ...
[NEW DEPS] ARM/arch/arm/generated/inc.d -> arm-deps
[ENVIRONS] arm-deps -> arm-environs
[ SHCXX] ARM/enums/AddrMap.cc -> .os

ext/pybind11/include/pybind11/common.h:70:20: fatal error: Python.h: No such

#include <Python.h>
^
compilation terminated.
Now since we aren't supposed to have python in the mix in this library, I
suspect that the configure step of gem5.opt is leaving behind some things that
are getting picked up by the subsequent library build.
if I reverse the build steps:
rm -rf build
scons -j32 --without-python --with-cxx-config build/ARM/libgem5_opt.so
scons -j32 build/ARM/gem5.opt
Both the library and binary build OK, but when I try to run gem5.opt with fs.py
I get:
Traceback (most recent call last):
File "<string>", line 1, in <module>

line 65, in <module>
"atomic" : objects.params.atomic,
AttributeError: 'module' object has no attribute 'atomic'
(This does not happen with a clean build of gem5.opt; the sim works fine if I
first remove the build folder)
I'm afraid my scons skills aren't nearly good enough to figuring out where to
look. Does anyone have any ideas?
Thanks,
Paul
