The kernel source code has been compiled successfully.
However, when i run the cmd: plugsched-cli dev_init /home/neu/workplace/work/newwork/kernel/kernel-4.9/ ./scheduler
It shows the errors:

It seems no useful infomation...
Could you try run:
/usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/kernel/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/kernel/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched
directly to see the result?
Hi,
When I run the command:
/usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/kernel/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/kernel/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched
The information is shown in the following:
[root@96d2615dad78 newwork]# /usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/kernel/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/kernel/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched
make: /home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched: No such file or directory
make: *** No rule to make target '/home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched'. Stop.
I visited the directory /home/neu/workplace/work/newwork/scheduler/working/ and found that the file Makefile.plugsched was not generated.
How do you use plugsched? Have you tried with latest plugsched or docker image?
Makefile.plugsched should be copied to scheduler/working/ from src/Makefile.plugsched at a very early time (during "init" or "dev_init", before "make collect")...
I use plugsched with this command: docker pull plugsched-registry.cn-hangzhou.cr.aliyuncs.com/plugsched/plugsched-sdk. Is this the latest plugsched?
[root@96d2615dad78 newwork]# cd scheduler/working/
[root@96d2615dad78 working]# ls
Makefile.plugsched analyze.py collect.py hotfix_conflict_check scheduler-installer springboard_search.sh version
init.py boundary.yaml extract.py plugsched.service scheduler.spec symbol_resolve
I recheck this folder, the Makefile.plugsched is exist. But when I run this command:
/usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/kernel/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/kernel/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/kernel/scheduler/working/Makefile.plugsched
It still prompts that there is no file Makefile.plugsched。

yes
[root@96d2615dad78 newwork]# cd scheduler/working/ [root@96d2615dad78 working]# ls Makefile.plugsched analyze.py collect.py hotfix_conflict_check scheduler-installer springboard_search.sh version init.py boundary.yaml extract.py plugsched.service scheduler.spec symbol_resolve

It still prompts that there is no file Makefile.plugsched。
Are you sure to run this command under /home/neu/workplace/work/newwork/kernel/scheduler/ path exactly?
[root@96d2615dad78 newwork]# cd scheduler/working/
[root@96d2615dad78 working]# ls Makefile.plugsched analyze.py collect.py hotfix_conflict_check scheduler-installer springboard_search.sh version init.py boundary.yaml extract.py plugsched.service scheduler.spec symbol_resolve
wait...
It seems Makefile.plugsched is in newwork/scheduler/working/
not newwork/kernel/scheduler/working/, right?
I'm a bit confused with your dir...
I'm sorry, there was an error in my previous command.
The Makefile.plugsched is exist in the dir: /home/neu/workplace/work/newwork/scheduler/working/
When I run the command:
/usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/scheduler/working/Makefile.plugsched --jobs=4
It shows the reply:
/home/neu/workplace/work/newwork/scheduler/working/Makefile.plugsched:4: Makefile: No such file or directory
make: *** No rule to make target 'Makefile'. Stop.
ok, then you should cd
/home/neu/workplace/work/newwork/scheduler/
and then run this command (after you dev_init failed)
After I cd /home/neu/workplace/work/newwork/scheduler/ and run this command. It show the follow information:
[root@96d2615dad78 scheduler]# /usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/scheduler/working/Makefile.plugsched --jobs=4

It seems our gcc 8 complained about this code. You need this patch on your linux source code:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=435bba0f11f06789be59757719c161915e92f889
I'm sorry to bother you again.
I fix the code according to your link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=435bba0f11f06789be59757719c161915e92f889
Then I run the "make" command again, it show the new errors and I can't find a solution online.

It seems gcc 8 is too new for your kernel version...
I'm curious about the result you simply type "make" under the Linux source code to build the kernel (in our container with gcc8)
For your question, please try:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=217c3e0196758662aa0429863b09d1c13da1c5d6
I'm sorry to create ambiguity. I'm run "make" command means run "/usr/bin/make collect objs= plugsched_tmpdir=/home/neu/workplace/work/newwork/scheduler/working/ plugsched_modpath=/home/neu/workplace/work/newwork/scheduler/kernel/sched/mod/ --file=/home/neu/workplace/work/newwork/scheduler/working/Makefile.plugsched --jobs=4"

I think it may be that the compilation failure of the kernel on AGX is associated with Nvidia's library.
I'm sorry to create ambiguity.
No ambiguity. I know you typed "make collect xxx", but I'm also curious about typing simply "make" to build the kernel.
I think it may be that the compilation failure of the kernel on AGX is associated with Nvidia's library.
So Nvidia's library cannot work with gcc 8. Actually I've found the reply from nvidia about your first build error:
https://forums.developer.nvidia.com/t/error-taking-address-of-packed-member-of-struct-regcache-rbtree-node-may-result-in-an-unaligned-pointer-value/158135
but I didn't say that because I hoped to solve this error and there would be no other errors :-(
However, change gcc version is hard for us, because some related libraries (e.g., our customized gcc-python-plugin) need to be rebuild...
Thank you for your reply. My version of Linux kernel can only be compiled with gcc 7.3.1, so these errors cannot be solved for the time being.
I run the command "make" in dir: /home/neu/workplace/work/newwork/scheduler, it shows the following errors:
