[Solved] Kernel tool: perf ?

[polikuo]

Hi, I'm taking a course in school.

The teacher wants us to install "perf" to see how our coding performs.

I've seen posts about compiling one with no luck. (aarch64)

Most of them say make -C <kernel source root directory>/tools/perf would do the trick.

On some web pages I see java may be required. (keyword: export JDIR="/usr/lib/jvm/open-jdk")

Is it perhaps locked in the kernel ?

I've never successfully compiled a kernel before.

Or do you have it around in your kernel build directory ?

[Juanito]

You don't need to compile the kernel, this worked for me:

Code: [Select]

$ cd linux-5.4.3
$ make -C tools/perf
It looks like you need compiletc elftools-dev openssl-1.1.1-dev perl5 liblzma-dev zstd-dev libcap-dev

You'll also need to add the arch specific flags.

[polikuo]

It looks like you need compiletc elftools-dev openssl-1.1.1-dev perl5 liblzma-dev zstd-dev libcap-dev

Which arch are you using ?

I don't see elftools-dev anywhere.

P.S. I'm using aarch64.
I don't have any other machine around right now.
Perhaps I should make a USB and boot into it 

[Juanito]

I did a test on x86_64 - you need libelf-dev on aarch64

You said this was for  aarch64.  Why is it looking in  arch/x86 ?

[polikuo]

You said this was for  aarch64.  Why is it looking in  arch/x86 ?

I honestly don't know.

Perhaps make just traverse every directories, doing ckecks ?

I assure you I'm using aarch64

I suspect you will need libelf from elfutils rather than libelf from http://www.mr511.de/software/

[curaga]

https://bugzilla.redhat.com/show_bug.cgi?id=1793473

So it's your gcc being too new for that perf version. You can likely find patches to make it build with that gcc.

[polikuo]

I suspect you will need libelf from elfutils rather than libelf from http://www.mr511.de/software/

 

The elfutils compiles successfully.
(./configure --prefix=/usr/local --enable-libdebuginfod=dummy --disable-debuginfod)

Since I'm lazy, I just do a sudo make install.

But perf still stuck at the same place after installing elfutils.

I have tried different versions of the kernel source code, they all stuck at the same place.

[Paul_123]

You likely need to have a valid .config in the kernel source tree.   You can get the current config

Code: [Select]

sudo modprobe configs
zcat /proc/config.gz > <path to kernel source>/.config

All of the errors with regard to multiple function definitions is likely due to gcc10.  Gcc is now very picky about properly using extern for external functions.  There maybe a -Wnoxxxxxxx flag to permit these errors.

You likely need to have a valid .config in the kernel source tree.   You can get the current config

I've created the .config file

What's happening here ?
Is it related ?

Hi polikuo

I think  CC  and  CXX  are only supposed to specify the compilers name but not compiler flags.

Clear CC, CXX, CFLAGS, CXXFLAGS, etc. Then, run the make command and see if the build system can figure out the
settings itself.

[polikuo]

Clear CC, CXX, CFLAGS, CXXFLAGS, etc.

Code: [Select]

unset CC CXX
make -C tools/perf clean
make -C tools/perf

The `-march=armv8-a+crc/arch' message is gone, but anything else stays the same

In function 'fprintf',
    inlined from 'perf_sample__fprintf_regs.isra' at builtin-script.c:602:14:
/usr/include/bits/stdio2.h:100:10: error: '%5s' directive argument is null [-Werror=format-overflow=]

Perhaps it requires certain library for __fprintf_chk ?
