Hi guys,
I have recently updated my Ubuntu to version 11.10. I have now huge problems
with the integrated gcc 4.6.1 and the newest (unstable) gem5. Compiling will
always stop with errors due to set but unused variables. I know that there
should be a trigger for that issue in the SConscript file, however it is not
working. While I could remove most of the problems, I am struggling with this
error:
build/ALPHA_SE/mem/protocol/DMA_Controller.cc:314:27: error: variable
'in_msg_ptr' set but not used [-Werror=unused-but-set-variable]
The problem here is, that this cc-file is generated out of a python file and
I cannot find the place where I can implement a workaround.
Has anyone an idea, what I need to change in order to build gem5 with gcc
4.6.1?
Thanks in advance,
Fabian Oboril
Take look at the file src/mem/protocol/SConscript. On line 101,
all the generated files are being added to the list of files that would be
compiled. You can replace Source(f) by Source(f,Werror=False). I think
that would sort out your current problem.
