We have a legacy Linux application, written in C, using GTK.
We compile it on Ubuntu14/32-bit, we can also launch it
In production, we run it on Debian10/32-bit
We have some very old hosts, which runs Debian 5. The old version of the application runs on Debian 5, but when we compile a new one, we got a runtime message:
.../bin/gui: symbol lookup error: .../lib/libmkt.so: undefined symbol: g_malloc0_n
It's strange, because nm finds it:
$ nm .../lib/libmkt.so | grep g_malloc
U g_malloc0
U g_malloc0_n
Also the application has a good reference entry to the library:
$ ldd .../bin/gui | grep libmkt
libmkt.so => .../lib/libmkt.so (0xb7257000)
This is happening only on the old machine with Debian 5:
$ uname -a
Linux kiosk 2.6.26-2-686 #1 SMP Mon Aug 30 07:01:57 UTC 2010 i686 GNU/Linux
On the new machine, with Debian 10, the application starts:
$ uname -a
Linux kiosk 4.19.0-17-686-pae #1 SMP Debian 4.19.194-1 (2021-06-10) i686 GNU/Linux
The developer machine with Ubuntu14, the application starts:
$ uname -a
Linux ubuntu-build-server 4.4.0-142-generic #168~14.04.1-Ubuntu SMP
Sat Jan 19 11:28:33 UTC 2019 i686 i686 i686 GNU/Linux
We start the application with LD_LIBRARY_PATH=.../lib .../bin/gui, we have a bunch of .so files in the .../lib directory, including the .../lib/libmkt.so, which indicates the error.
My hint is that the compiler uses some feature for libmkt.so, which the 2.6 kernel does not like, but I haven't found such issue on the internet.
UPDATE: .../lib/libmkt.so does not contain the missing g_malloc0_n symbol, but it refers to the GTK library, which does. What should I do in order to find such second-hop symbols?
Besides checking /boot/config_xx and /proc/config.gz, how to confirm the preempt rt option is enabled or not for a specific Linux kernel?
I can login to the OS by SSH and I have the root permission.
At command line you can do uname -a, that should show something like this.
~$ uname -a
Linux raspberrypi 5.10.35-rt39-v7l+ #2 SMP PREEMPT_RT Thu May 13 02:26:47 PDT 2021 armv7l GNU/Linux
~$
Then you can look up at top of the ssh window and see the same thing (palm slap to forehead is optional):
symetrix#192.168.2.45's password:
Linux raspberrypi 5.10.35-rt39-v7l+ #2 SMP PREEMPT_RT Thu May 13 02:26:47 PDT 2021 armv7l
The programs included with the Debian GNU/Linux system are free software; ...
String PREEMPT_RT (rather than just PREEMPT or other such scheduler terms) tells what is up.
first, I tried command
./Miniconda3-latest-MacOSX-x86_64.sh
and it reports that
line 296:
/data/keeling/a/xinyix3/miniconda/pkgs/python-3.6.0-0/bin/python:
cannot execute binary file ERROR: cannot execute native osx-64 binary,
output from 'uname -a' is: Linux keeling.earth.illinois.edu

I am really new to Linux. Is there any suggestions of failure of installation?
You seem to be running the wrong binary/script for Miniconda. Use the Miniconda3-latest-Linux-x86_64.sh script if you're on linux, not the OSX one.
On Intel processors
Linux linux-epq2.site 3.7.10-1.11-desktop #1 SMP PREEMPT Thu May 16 20:27:27 UTC 2013 (adf31bb) x86_64 x86_64 x86_64 GNU/Linux
to fetch the cache details:
cat /sys/devices/system/cpu/cpu*/cache/index*/
Where * is the respective cpu and cache index numbers
However, on ARM processors, this file/folder is not available. Is there a way to fetch these details?
Linux arndale 3.9.0-rc5+ #8 SMP Tue Apr 9 12:40:32 CEST 2013 armv7l GNU/Linux
From ARMv8A (64bit), it is possible to get cache info from CLIDR register. So cache info can be populated to /sys file system in Linux. Check detail from kernel/arch/arm64/kernel/cacheinfo.c.
I am trying to build openjdk from source and I am using "HOTSPOT_RELEASE_VERSION=20.0-b12" on openjdk6 on ubuntu 12.04.
It prompts:
This OS is not supported:" `uname -a`; exit 1;<br>
This OS is not supported: Linux joker-Inspiron-1545 3.2.0-35-generic-pae #55-Ubuntu SMP Wed Dec 5 18:04:39 UTC 2012 i686 i686 i386 GNU/Linux.
Can someone guide me on this please ?
change hotspot/make/linux/Makefile
SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 2.7% 3%
An easier way than editing a file is to set the environment variable
DISABLE_HOTSPOT_OS_VERSION_CHECK=ok
