One thing to try if you are desperate: symlink every needed shared
library into a directory, and then redirect /lib64 or that directory.
I'm pretty sure this should work.
I'm not sure why LD_LIBRARY_PATH does not work. I would dig dieeper
and try to understand that, theoretically it feels like it
Hi All,
I am trying to run SPEC-2017 benchmarks (compiled with Clang-3.5), on Gem5 in
SE mode (unmodified stable version v20).
However, I am getting segmentation faults in the x86 Decoder of Gem5, (free of
uninitialized pointer by tcmalloc).
The segmentation fault arises from a line in an auto-
Hi, Bobby,
Thanks for the reply. I have identified that the reason is the simulator
can not load the shared libs used by the benchmark. The benchmark I used
needs some shared library and needs to reset the LD_LIBRARY_PATH
environment variable. And when I run it with gem5, the error message is

Hey Shougang,
Can you provide us with a few more details?:
- The version of gem5 you are using.
- The exact command you are executing.
- The benchmarks used (and where they may be obtained, if possible).
- The exact output, including error, you received.
Kind regards,
Bobby

Furat,
It's been several years since I've played with the PARSEC suite, but some
applications can be run (or built?) in a way that increases or decreases
their execution time. I know, for example, bodytrack can be tweaked to be
slower or faster given depending on how accurate you want your trackin
Hi, All,
I am currently trying to run some benchmarks that need some shared libs. If
I run these benchmarks on physical machines, I need to
reset LD_LIBRARY_PATH to load these libs.
But when I run the benchmarks with gem5, I tried to use --env options and
--redirects options to set LD_LIBRARY_PAT
No problem!

P.S For the future, may I suggest you to reply to the message rather than
creating a new one?
In this way it will be easier for other people to follow the thread if it is

OK, the previous --redirects idea makes no sense, nevermind, I wish I
could edit emails.

--redirects can be used multiple times. But not 100% sure it will be
able to replace LD_LIBRARY_PATH. Just one thing worth trying along
--redirects /path/in/ld/libray/path=/usr/lib --env does change env
vars, but not 100% sure is it enough to make LD_LIBRARY_PATH work. In
theory it might, but not s
Yes I think the commit message is referring to an old version of the patch.
Now the option is in

I do see that forum, but I need to add multiple shared libs with
"LD_LIBRARY_PATH" environment variable, can I use multiple redirects to add
it multiple times? I mean, Can I use it like "--redirects
LD_LIBRARY_PATH=/some/path; --redirects LD_LIBRARY_PATH=/some/path" ?
And also, I noticed someone i
Hi Giacomo,
thanks for your fast reply :) I got the patch and just finished building it.
May I ask a quick question though? I actually wasn't allowed to set the

it on the command line options. How do I then set the

In syscall emulation mode. I tried to use --env option with myse.py, but it
still shows the same error.

Hi Oivind
I suggest you to have a look at the following patch which is currently under
review:
https://gem5-review.googlesource.com/c/public/gem5/+/28628
This will make it possible to dump stats starting from a user specified root
node (in the simobject hierarchy). For example, if you are just
Hi all,
I'm trying to remove certain stats from the stats file, but I'm struggling to
find an efficient way to do so. Just as an example, for the perBankRdBursts in
dram memory, it's to be found in /src/mem/dram_ctrl.cc and .hh. When I'm
commenting those out I can't rebuild without getting erro
