Issues with setting up VxWorks 7 SDK dev environment

Wind River Labs VxWorks SDK

Hi

Trying to set up VxWorks 7 SDK for QEMU on Debian 12. There are several issues:

$ sudo apt install build-essential libc6:i386

E: Unable to locate package libc6:i386

Resolve:

$ sudo apt install build-essential libc6-dev

Installing pytfpdlib:

$ sudo apt install python-pip
$ sudo pip install pyftpdlib

… However the following packages replace it: python3-pip
E: Package ‘python-pip’ has no installation candidate

Resolve:

$ sudo apt install python3-pip

$ sudo pip install pyftpdlib

error: externally-managed-environment

Resolve:

$ sudo pipx install pyftpdlib

Finally, starting a local FTP server on port 21 with user “target” and password “vxtarget” and FTP root in the current user’s home can be done as follows

$ sudo python -m pyftpdlib -p 21 -u target -P vxTarget -i 127.0.0.1 -d $HOME

I tried:

sudo python3 -m pyftpdlib -p 21 -u target -P vxTarget -i 127.0.0.1 -d $HOME

Error:

/usr/bin/python3: No module named pyftpdlib

This time I am facing a dead end, no resolve can be found.

Any suggestion to solve it?

Hi John,

Running the following commands in a debian:12 container allows me to start the FTP server provided by pyftpdlib.

apt install build-essential libc6-dev
apt install python3-pip
apt install python3-pyftpdlib
python3 -m pyftpdlib -p 21 -u target -P vxTarget -i 127.0.0.1 -d /tmp

As far as I can tell from the pipx documentation, its purpose is to provide isolated environments for each application, so I’m assuming pipx install pyftpdlib did not install pyftpdlib in a globally accessible location.

Using python virtual environments is another valid option for installing pyftpdlib with pip3. You just have to remember to source the environment before using the pyftpdlib module.

Regards,
Dan

HI Dan

Thank you, apt install python3-pyftpdlib works good. VxWorks boots (release version 23.03).

To proceed by following Creating and deploying Python applications I got the following:

[vxWorks *]# cd /usr
[vxWorks *]# python3
Launching process 'python3' ...
Process 'python3' (process Id = 0xffff800000363570) launched.
0xffff800000368ca0 (iPython3): RTP 0xffff800000363570 has been deleted due to signal 11.

RTP 0xffff800000363570 has been deleted due to signal 11?

You need run rtpSpStackSize=0x1000000 in the C shell before starting the python interpreter.

-> rtpSpStackSize=0x1000000
rtpSpStackSize = 0xffffffff80c33230: value = 16777216 = 0x1000000

Thank you, it works.
Now I have tried out the foo.vxe and python3 examples. Both of them work.

I wish to dig deeper into VxWorks application development by reading the VxWorks Getting Started, 23.03 web page. As far as I can see most of the links there are not open to public with Error 404.

I tried Visual Studio Code Getting Started and Kernel Application Development.

They seem to be restrictive to non-commerical license holder.

Is there any documentation on application development particularly on VxWorks workbench 4 / VS Code?
