./pt_linux_x64 doesn't work on my x64 machine

[starz]

$ ./pt_linux_x64 # there is no output
$ strace ./pt_linux_x64 # prints
execve("./pt_linux_x64", ["./pt_linux_x64"], [/* 33 vars */]) = -1 ENOEXEC (Exec format error)
write(2, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
exit_group(1) = ?
+++ exited with 1 +++

and here is the information about my machine:
Linux version 4.18.0 (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.11)) #1 SMP Fri Sep 24 02:26:50 CST 2021

sorry, it's because my file upload is incomplete

[David (PassMark)]

OK, glad you sorted it out.

OK, glad you sorted it out.

Unfortunately I have the same problem as the OP, but not a corrupted download. I'm running Ubuntu 20.04.3 LTS, and can't get past

./pt_linux_x64: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

I already set LD_LIBRARY_PATH to /snap/core18/2128/lib/x86_64-linux-gnu where I located libncurses.so.5 on my computer. However, I still get the same error message. What to do?

Thanks, Rainer

See the FAQ question: 'I am getting "error while loading shared libraries: libxxx.so.x: cannot open shared object file:
No such file or directory?" error when I launch BurnInTest Linux from the command line, why?'

On this page: https://www.passmark.com/support/bitlinux_faq.php

Should apply for PerformanceTest as well.

- libncurses.so.5

Some newer versions of Linux are now shipping with a newer version of ncurses (6) than BurnInTest was built with (eg Fedora 25). If you see this error messages you should be able to install "ncurses-compat-libs" which will install a version 5 compatible ncurses library. You can do this with "yum install ncurses-compat-libs".


- libtinfo.so.5

Some distributions split the ncurses library into several files and others use a single file. If you are missing the libtinfo library you can create a link from the ncurses library to it. First check where the libncurses.so.5 library is being linked from by running the ldd command, eg "ldd bit_cmd_line_x32" it should be /lib or /usr/lib.

Then create links to the ncurses library like this (changing /lib to /usr/lib if necessary);
ln -s /lib/libncurses.so.5 /lib/libtinfo.so.5
ln -s /lib/libtinfo.so.5 /lib/libtinfo.so

When using a 64 bit version of linux and running bit_cmd_line_x64 you would need to link the 64 bit libraries;

ln -s /lib64/libncurses.so.5 /lib64/libtinfo.so.5
ln -s /lib64/libtinfo.so.5 /lib64/libtinfo.so

The same problem with outdated ncurses lib on Ubuntu 21.10 (./pt_linux_x64: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory). The same will be with coming LTS release Ubuntu 22.04.
Not possible to install "ncurses-compat-libs".
Please compile with contemporary libraries.

[Tim (PassMark)]

You can still install libncurses5 in Ubuntu 21.10;

sudo add-apt-repository universe
sudo apt-get install libncurses5

Linux is a dumpster fire for binary compatibility.
If we compiled with the newest library, then the software wouldn't work on even slightly old machines.

i had to install 2 packages for ubuntu 22.04 since libncurses5 would only offer i386 for some reason.

went here and downloaded
1. https://www.ubuntuupdates.org/packag...ates/libtinfo5
and
2. https://www.ubuntuupdates.org/packag...es/libncurses5

the amd64 versions respectively
and installed via "sudo dpkg -i" number 1 and 2.

maybe for 24.04 newer versions are required.

EDIT> sorry, i am on 24.04 , maybe this solution is needed only for 24.04< or works also for 22.04?
in any case , with 24.04 now able to run ./pt_linux. Passmark Performance Linux Test.

What steps can I take to resolve the "error loading shared library: libxxx.so.x: cannot open shared object file: No such file or directory" error when launching BurnInTest Linux from the command line?

[David (PassMark)]

Note that post was about PerformanceTest (which is different software from BurnIntest)

But see the Linux FAQ page for details about Linux shared libraries for BurnInTest.
https://www.passmark.com/support/bitlinux_faq.php
(the problem is similar for all Linux software however)

[Alelele98]

To install libncurses5 on Ubuntu 24.04 and newer:

echo "deb http://security.ubuntu.com/ubuntu focal-security main universe" > /etc/apt/sources.list.d/ubuntu-focal-sources.list
apt update
apt install libncurses5

[raywood]

On U 24.04, that echo command (even when preceded by sudo) results in "Permission denied."

Is it possible for you to statically link the ncurses library?
