Problem with esp32 debug for Ubuntu. (undefined symbol: _Py_ZeroStruct)

mikelisfbay · May 16, 2020, 10:14pm

Hi all,

I have Expressif ESP Debug board and ESP32 Dev Module.

I just installed VS Code and Platform IO.

First error.
undefinedpiogdb: error while loading shared libraries: libncurses.so.5: cannot open
shared object file: No such file or directory
undefinedpiogdb: error while loading shared libraries: libtinfo.so.5 : cannot open
shared object file: No such file or directory

I link some version 6 to version 5 files.

lrwxrwxrwx  1 root root       43 May 11 16:51 libncurses.so.5 -> /usr/lib/x86_64-linux-gnu/libncurses.so.6.2
lrwxrwxrwx  1 root root       41 May 11 16:54 libtinfo.so.5 -> /usr/lib/x86_64-linux-gnu/libtinfo.so.6.2

I get another error when the first two errors are gone.
undefinedpiogdb: symbol lookup error: piogdb: undefined symbol: _Py_ZeroStruct

Then, I installed libncurses5-dev.

sudo apt-get install libncurses5-dev libncursesw5-dev

It did not help.

Thanks for any suggestion on how to fix this error. Thank you!
Michael

Did you remove your old symlinks thereafter?

What version of Python do you have installed?

Which version of Ubuntu are you running?

Do you have Anaconda Python installed on the system?

mikelisfbay · May 18, 2020, 1:35am

Thank you for helping me. Here are the answers to your questions.

Did you remove your old symlinks thereafter? I removed them today. It doesn’t help.
What version of Python do you have installed? Python 2.7.18rc1 /user/bin/python
Which version of Ubuntu are you running? Ubuntu 20.04 LTS (Just installed from scratch a week ago.)
Do you have Anaconda Python installed on the system? No.

I have also installed Platform IO and set up the debug mode on my Windows 10 PC. It works flawlessly. So, the hardware and software should be working. It may be just some setup issue. I would love to have it running under Ubuntu!

Below shows the details on how I removed the symlink and tried to install version 5.

Yesterday, I created these 3 symlinks for the errors displayed by Platform IO.
sudo ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6.2 /usr/lib/x86_64-linux-gnu/libncurses.so.5
sudo ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6.2 /usr/lib/x86_64-linux-gnu/libtinfo.so.5
sudo ln -s /usr/lib/x86_64-linux-gnu/libpython3.8.so.1.0 /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0

Today, I removed these 3 symlinks.
sudo rm libncurses.so.5
sudo rm libtinfo.so.5
sudo rm libpython2.7.so.1.0

I get the same error regarding version 5 again. I have version 6 installed.
undefinedpiogdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory (taken Platfrom IO Debug Console Window)

I tried to install version 5.

Version 6.2 is installed. It doesn’t make the errors go away.

maxgerhardt · May 18, 2020, 10:40am

Python2 has been deprecated for ages with PlatformIO use. But it also shouldn’t be used here anyways. You also have Python3 of version 3.7.x? (Python 3.8 seems to have problems).

Also make sure that the command

$ cat  $(which piodebuggdb) 
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import re
import sys

from platformio.__main__ import debug_gdb_main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(debug_gdb_main())

outputs a shebang for python3.

mikelisfbay · May 18, 2020, 12:30pm

I see. I begin to understand PlatformIO. PlatformIO is written completely in Python language. It relies on Python Interpreter and libraries to work correctly. I need help to run your suggested command and Python code.

cat $(wchich piodebuggdb)

The system executes this commamd, but it does not return. I waited for a long time and had to kill it with control-C. Where should I run this command?

python main.py

raceback (most recent call last):
File “platformIOdebug.py”, line 6, in
from platformio.main import debug_gdb_main
ImportError: No module named platformio.main

It seems that I don’t have platformio module. I am confused that the module should be installed since I already have Platform IO installed. Can you help me on this? Do I need to install python3.7 first for my Linux system?

Thank you,
Michael

maxgerhardt · May 18, 2020, 12:58pm

Indeed, see GitHub - platformio/platformio-core: Your Gateway to Embedded Software Development Excellence 👽.

That might just indicate that the PIO tools aren’t callable from your CLI because they aren’t in the PATH. The VSCode extension installs PIO in some other directory that’s not in your PATH. This is probably completely separate from your original problem - If you want, you can use the installer script (or sudo -H pip3 install platformio) to install it and then switch the VSCode PIO extension settings to not use the built-in core

What problem are you stuck at now? The ncurses error is gone when you install ncurses6 and symlink it to the ncurses5 names?

After all, the ESP32 debug command should start the xtensa gdb. Are there any errors when directly starting

~/.platformio/packages/toolchain-xtensa/bin/xtensa-lx106-elf-gdb

on the commandline?

mikelisfbay · May 18, 2020, 6:20pm

Thank you for your reply again. I got the error with ncurses5 back from I deleted the symlink. The ncurses5 installation did nothing because I already have ncurses6.2 installed. I am back to the original issue. I remember I also get an error message about not finding libpython2.7.

I am wondering if I installed VS code correctly. I installed through the graphical snap store. I did see a download package you can use to install VS code. I guess that my problem is not related to VS code but Platfrom IO. Is that correct?

I will try to install PlatfromIO by PIP3. I will check whether I have Python3.7 installed or not. I will let you know how it goes.

Thank you for your patience and knowledge!!!
Michael

mikelisfbay · May 19, 2020, 2:52am

I am able to move along with your suggestions. I have completed some steps, but I am unable to get the most important command to run.

I installed Python 3.7 --> python3.7 is the command to invoke.
I installed pip3
I installed Platorm IO with sudo -H pip3 install platformio command
I changed the setting to not use the built in core.

I could not get this command to run. I can’t find the gdb file. I don’t know where platformio is installed.
~/.platformio/packages/toolchain-xtensa/bin/xtensa-lx106-elf-gdb

I need some help to test whether I can errors when directly starting the debug command directly.
Michael

maxgerhardt · May 19, 2020, 9:05am

This will only be there when the toolchain is installed. Make sure to first create some random ESP32 project and compile it, that will cause the toolchain to be compiled. And ~/ your home folder, aka /home/<user>/.platformio/... etc.

You can also do that from the cmd line:

mkdir test_prj
cd test_prj
pio init -b esp32dev
pio run

(will not compile without source files but will download the toolchain).

mikelisfbay · May 21, 2020, 1:03am

Hi Max,

Thank you for your instructions. I have successfully built a simple LED blink project and uploaded iinto my ESP32 Dev board using the command lines.

It turns out that the path and gdb file names have been changed. I am able to find the gdb file and run it. I get the same libncurses.so.5 error.

So, it fails to run outside VS Code Editor.

maxgerhardt · May 21, 2020, 1:37pm

The upload method used in PIO / VSCode was the serial bootloader by default, and that doesn’t involve GDB, so there’s no difference in behaviour out- or inside VSCode.

The FAQ suggests replacing binaries which I don’t think is really good. I don’t get why Ubuntu provides libncurses5 (and libtinfo5, libncursesw5) when all they do is install the libncurses6 version of it. That defeats the purposes of having these packets… I’ll try in a VM to see what’s going on there.

mikelisfbay · May 21, 2020, 2:17pm

Thank you.

I am studying Libncurses.so.5 because I don’t even know what it is for and what it does.

I found this link that someone has successfully installed Libncurses5 on Mint Linux. So, I was hopeful that the solution would work on Ubuntu. So far, it does not wrok on Ubuntu. I am surprised why the GDB tool is not flexible enough to use the latest version 6.

At the same time, I am very happy that I am very close to getting Platform IO tools to work on Ubuntu. It can build, monitor, upload via \TTY\ USB0 and upload via OTA method (ip address). It will be perfect if GDB works. GDB is very important to have.

Thank you for all your help.

Indeed Ubuntu 20 support seems to lacking / hacky right now. I installed a fresh Ubuntu 20.04 LTS in a VM. Even got an install error in VSCode which was solvable though. The problem with the xtensa-esp32-elf-gdb is however reproducable:

max@max-VirtualBox:~/.platformio/packages/toolchain-xtensa32/bin$ ldd xtensa-esp32-elf-gdb 
	linux-vdso.so.1 (0x00007ffdc2af0000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fed2a94f000)
	libncurses.so.5 => not found
	libtinfo.so.5 => not found
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fed2a800000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fed2a7dd000)
	libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007fed2a7d8000)
	libpython2.7.so.1.0 => not found
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fed2a5e4000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fed2a968000)

So it’s missing libncurses.so.5, libtinfo.so.5 and libpython2.7.so.1.0.

With the default ncurses state

$ ls -la /usr/lib/x86_64-linux-gnu/libncurses*
lrwxrwxrwx 1 root root     17 Mai 22 00:02 /usr/lib/x86_64-linux-gnu/libncurses.so.6 -> libncurses.so.6.2

lrwxrwxrwx 1 root root     18 Mai 22 00:02 /usr/lib/x86_64-linux-gnu/libncursesw.so.6 -> libncursesw.so.6.2
-rw-r--r-- 1 root root 231504 Feb 26 08:14 /usr/lib/x86_64-linux-gnu/libncursesw.so.6.2

I did the following:

sudo apt install libncurses5 libtinfo5 libncursesw5 python2.7 libpython2.7

Which fixes all library errors in ldd for me:

max@max-VirtualBox:~/.platformio/packages/toolchain-xtensa32/bin$ ldd xtensa-esp32-elf-gdb 
	linux-vdso.so.1 (0x00007ffc35fb0000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f7d04d52000)
	libncurses.so.5 => /lib/x86_64-linux-gnu/libncurses.so.5 (0x00007f7d04d2c000)
	libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007f7d04cfe000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f7d04baf000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7d04b8c000)
	libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f7d04b87000)
	libpython2.7.so.1.0 => /lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007f7d04819000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7d04627000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f7d04d6b000)
	libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f7d0460b000)

And GDB starts up:

max@max-VirtualBox:~/.platformio/packages/toolchain-xtensa32/bin$ ./xtensa-esp32-elf-gdb

Now the question is: Why in the world doesn’t this work for you when you do the same thing?

Can you:

remove all previous symlink hacks regarding ncurses5
the output of ldd ~/.platformio/packages/toolchain-xtensa32/bin/xtensa-esp32-elf-gdb
the output of sudo apt install libncurses5 libtinfo5 libncursesw5 python2.7 libpython2.7
again the output of the ldd command

mikelisfbay · May 22, 2020, 1:10am

Hi Max,

Thank you so much for all your great effort. I am able to get the same result as you do. GDB can run from the command line. Now, I go back to VS Code and run the debugger within VS Code. Those old errors do not appear anymore. I am getting closer now.

Now, GDB can go further. It stopped when it failed to find my ESP debugger board (/tty/USB1 or /tty/USB2) with a different type of errors.

Hi Max,

Thank you for your awesome help on the _Py_ZeroStruc and lib ver5 errors. Now, the new problem with the driver not found deserves to have a new post on the forum. I am making a new post for the new error now. Other people will know that I am having a different problem.

I have marked your suggestion as the solution. So, you are credited for finding the solution!!!

Best regards,
Michael

It seems latest ubuntu is using ncurses6 and apt-get installs ncurses6 even if ncurses5 is meant to be installed. Try this.

sudo add-apt-repository universe
sudo apt-get install libncurses5
sudo apt-get install libncursessw5

I checked libncurses5 are installed as below.

lrwxrwxrwx 1 root root 17 2월 26 16:14 libncurses.so.5 -> libncurses.so.5.9
-rw-r–r-- 1 root root 149736 2월 26 16:14 libncurses.so.5.9
lrwxrwxrwx 1 root root 17 7월 31 23:09 libncurses.so.6 -> libncurses.so.6.2
-rw-r–r-- 1 root root 162024 2월 26 16:14 libncurses.so.6.2
lrwxrwxrwx 1 root root 18 2월 26 16:14 libncursesw.so.5 -> libncursesw.so.5.9
-rw-r–r-- 1 root root 198736 2월 26 16:14 libncursesw.so.5.9
lrwxrwxrwx 1 root root 18 7월 31 23:09 libncursesw.so.6 -> libncursesw.so.6.2
-rw-r–r-- 1 root root 231504 2월 26 16:14 libncursesw.so.6.2

My problem is I still see error for libncursesw.so.5 is missing for PIO debug.

mikelisfbay · August 13, 2020, 1:14pm

Hi Jmin,

Yeah. It is frustrating to see that problem again.

Max and I have spent much time to install the debugger. We finally got to run. Unfortunately, I have learned that the debugger is very unstable with Linux. I went back to do all my debugging on Window 10 platform only.

I think that the PIO team needs to be informed about the issue. Hope they can fix the underlying issues.

I suggest running the debugger on other platforms (like Window 10) for your projects if you can.

Best,
Michael

maxgerhardt · August 13, 2020, 1:27pm

lsb_release -a output please?

libncursesw.so.5 seems to be there on your computer though… is it also for the xtensa32 gdb debugger?

mikelisfbay · August 13, 2020, 2:36pm

Hi Max,

I was telling Jmin that the debugger for esp32 has been unstable lately. Hope you find something new with Jimin. I would be happy to show you the error messages (when I run the debugger) if you’d like to know.

Thank you for your frequent help on this forum!

Best,
Michael

jmin.yoo · August 18, 2020, 5:12am

Hi Max,

I actually use Mint 20 as below. When I checked ubuntu, ubuntu 18 was using version 6.

|Distributor ID:|Linuxmint||—|---|
|Description:|Linux Mint 20|
|Release:|20|
|Codename:|ulyana|

Yeah… libncurses.so.5 is there but I see such error. I’m trying to debug a risc-v board from sipeed.
