Compile of Tasmota 14.2.0 failed for ESP32C3. UPDATE: Error is back on14.2.0.6 and 14.3.0 pre-release

[helmar74]

Hi, I tried to compile Tasmota 14.2.0 for ESP32C3.

I only changed that in platformio_override.ini:

                          tasmota32c2

everything else is on "default"

I got the following error:

It worked before with 14.1.0

[arendst]

Ah windows and as.exe again.

Welcome to the club.

[helmar74]

ok, happy to be in the club...
what does it mean?

[barbudor]

What exactly did you change ?

You shouldn't have to change anything but only select the correct target in VisualCode, and when platformio has done its trick, click the build button

[helmar74]

that's what i did. Comment out all target, only tasmota32c3 is choosen.

[barbudor]

That's what I said
You shoulddn't have to change anything in any file
Just select the target in the UI:

[helmar74]

Will try:
[platformio]
core_dir = c:.platformio
workspace_dir = c:.pio

as mentioned here:
#21941
I'll report back

[barbudor]

Hum, I can reproduced
strange
there's no obvious reason

[barbudor]

it ends differently in my case but still related to as.exe

[arendst]

Try this https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry

[barbudor]

@arendst it's already there

[barbudor]

And I don't see any long path here. The path to as.exe, even with all ../.. is around 136 characters

[helmar74]

Changing
[platformio]
core_dir = c:.platformio
workspace_dir = c:.pio

in platformio_override fixed it.

Thanks a lot

[helmar74]

The error is back!
I tried to compile (only for test reasons) pre-release 14.3.0.
Im using VSC on Windows
I changed in registry to enable long paths:

I also changed default directories in platform_override.ini:

; For best Gitpod performance remove the ";" in the next line. Needed Platformio files are cached and installed at first run
core_dir = c:\.platformio
; For unrelated compile errors with Windows it can help to shorten Platformio project path
workspace_dir = c:\.pio

When I try to compilfe for esp32c3 I get the following error:

[arendst]

It's not a Tasmota error. It's a platformio error.

In the end I moved to WSL on windows and run platformio on Ubuntu while running VSC in windows. It even compiles faster than pure windows.

[helmar74]

Hi and thanks for the info.
Sad to hear, as I can compile ESP8266, ESP32 and also tasmota32c2 under windows. I was also able to compile until version 14.2.0 on windows environment. Maybe it's a Core3 Issue for ESP32C3?

I only run 3 ESP32C3 based devices. So this devices will stay on 14.2.0.

[helmar74]

Is there anyone who is able to compile 14.2.0.6 on windows?

[helmar74]

Instead of installing ubuntu learn to use WSL. In that case you still run VSC on windows but platformio on WSL (which is default ubuntu).

Im running Backups of my Windows machine with dism tool. This fails when wsl is installed. I still want to Unterstand what is causing the issue in newer Versions as 14.2.0...

[ulfh2018]

Just tried to change the settings in platformio_override.ini acording to the recomendation in this tread. Worked like a dream!!!!
Thanks a lot to helmar74!!!!

Which Tasmota Version die you compile?
IT worked for me with 14.2.0, all later Versions failed.
You can also try to compile a other Version and than Switch back to tasmota32c3.
This also failed for me

[ulfh2018]

I am running 14.2.0.6
Tried to compile for esp8266 - which worked OK and the switched back to ESP32c3
Worked OK - though I hae not tested the image yet

[helmar74]

OK for me it worked Not with esp32c3.
I did a cleanup of platformio but also No success.
Maybe i`ll give it a try in a new Maschine...

[helmar74]

I started the process with removing VSCode, using Revo Uninstaller, then I deleted the .platformio directory, rebooted and installed from scratch. Had several versions of Tasmota on my system, and deleted everything before I downloaded the .zip file, unzipped and moved the tasmota-development (bottom directory) to where I wanted it to be. Did not work until I changed the platforio_override.ini. Next step would have been to install Ubuntu on a virtual machine.

[Jason2866]

Windows hits its limits with path length limitation. Platformio is just not doing crude workarounds for Windows to get big Projects going. Don't waste your time trying to workaround for a limitation Microsoft is not willing to solve since many many years. There are issue free alternatives

The shorten of the project path will not work very long. With every library or source file added to Tasmota the command line for the compiler, linker and assembler will get longer.

[helmar74]

Ok inmy Linux VM IT works, so fine for me. Will Close discussion in a few days

[Jason2866]

Probably it is faster too, since Windows Defender is not anymore horribly slow down the compile process.

[Wintespe]

I ran the command getconf -a in the console under Linux Mint. This resulted in the following values

@Mint:~$ getconf -a
LINK_MAX                     65000
_POSIX_LINK_MAX              65000
MAX_CANON                    255
_POSIX_MAX_CANON             255
MAX_INPUT                    255
_POSIX_MAX_INPUT             255
NAME_MAX                     255
_POSIX_NAME_MAX              255
PATH_MAX                     4096
_POSIX_PATH_MAX              4096

The description of the values

LINK_MAX
Specifies the maximum number of links that this file can have.
MAX_CANON
Specifies the maximum number of bytes in the workstation's canonical input queue (before line editing).
MAX_INPUT
Specifies the space available in the workstation's input queue.
NAME_MAX
Specifies the largest filename size.
PATH
Specifies the standard PATH setting.
_CS_PATH
Specifies the standard PATH setting.
PATH_MAX
Specifies the maximum number of bytes in a path name.

The result surprised me:
NAME_MAX 4096
PATH 4096
If I interpret this correctly, there are restrictions on the path length under Linux.
Does this mean that compiling projects on Linux - like Tasmota - under PlatformIO can run into problems?

[sfromis]

Well, 4KB is indeed a pretty typical max path length on Linux, meaning that projects are expected to not exceed this high limit, about 100 lines. I'm not aware of projects getting near this ceiling.

Where people have trouble is on Windows, where path names longer than ~256 seems to not be supported 100% of the time, but I'm not doing much in Windows anyway.

[Wintespe]

Well, with the help of Mark Russinovich's ProcMon, I took a look at what PlatformIO actually does when Tasmota is compiled. The result is amazing. I haven't found any path lengths longer than 168 bytes in my environment. However, the command line that is sent to as.exe exceeds a length of 4096 bytes, wow. Maybe that's where the problems lie. However, these depend on the PlafformIO.

Tried all mentioned workarounds - no luck so far.
btw - all other variants (esp8266, esp32 etc.) do build.

[tefod-zz]

Thought about that. Are u using a VM or WSL? Honestly, I like the portability of VSC, which works great for me everywhere 🤷‍♂️

[arendst]

I prefer WSL. Works great.

[helmar74]

I'm using Linux Mint in a VM with VMware Workstation Personal.
I installed VSC in the VM.
So I can use the advantages of VSC combined with error free comipilation

[Jason2866]

Yep, the only future proof solution for Windows users to compile Tasmota is using WSL or Linux in a VM.
The reason is the long generated command from Platformio when calling as.exe
When this command has more than 4095 bytes it fails.

[tefod-zz]

I'm using Linux Mint in a VM with VMware Workstation Personal. I installed VSC in the VM. So I can use the advantages of VSC combined with error free comipilation

Thx. For some specific projects, I even use Alpine Linux, so I'm not completely new to Linux 😁
However, portability is an issue for me since I can't install VMware on every machine, especially at work. Additionally, the overhead of a full Linux OS can be impractical. Even Alpine with Xfce would take around a gigabyte.

I haven't explored WSL yet, but it seems like I should give it a try now. In the meantime, I'm thinking of setting up an Alpine VM or appliance with VSC on my home lab (proxmox). That way, I could access it via RDP/SSH & SCP anytime.

[helmar74]

This worked for me also until tasmota 14.2.0. From 14.3.0 on it wasn't working anymore.
Just want to mention, that compiling with linux (in a VM) is much faster as compiling on a physical windows machine.
That sound's cracy, but is a fact ;-)

[joba-1]

you won‘t notice much differeces between using a vm hosting environment like vmware or wsl once you have setup the vm properly.
But the integration of wsl is better imo since distros provide special images taylored for it. You usually get networking setup, can run X Windows gui programs seamlessly on the windows desktop, have a share of windows drive in wsl and of the wsl drive in windows.
Opening a wsl terminal does not require an additional program like putty. All just by installing the distro via a simple wsl command. No further setup needed to get all that.

Regarding VSCode: you have the option of running the linux variant in WSL or use the remote dev extension with the windows variant. I prefer the latter.

Have fun…

[Wintespe]

As I noted above, the problem is probably the length of the command line that PlatformIO sends to as. It exceeds 4095 bytes. The limit for Windows is 8k. As far as I know, the limit for Linux is 32k. The other ID's, such as VisualStudio 2022 etc, work around the problem by creating a file with the commands and passing it to the appropriate tool . I hope Platformio will add this functionality in one of the next versions. At some point, even at 32k, the limit will be exceeded with the command line. For now I'll wait until it burns out on me.

[Jason2866]

Platformio development seems stalled (it is an Ukraine company)

[Wintespe]

Yes, I know that. Hopefully the disaster will stop.
