v4.4 on Raspberry Pi 4 ... "gcc is not able to compile a simple test program." (IDFGH-6180) #7857

csBlueChip · 2021-11-08T22:02:43Z

Hi.

If I do this everything works exactly as expected:

# Install IDF
export IDF_TOOLS_PATH=/home/esp/tools/
mkdir /home/esp/idf
cd /home/esp/idf
git clone -b v4.3.1 --recursive https://github.com/espressif/esp-idf.git .
./install.sh

# Pull fix for broken CA file
cd /home/esp/idf/components/mbedtls/esp_crt_bundle
mv  cacrt_all.pem  cacrt_all.pem.orig
wget https://raw.githubusercontent.com/electrocucaracha/esp-idf/4e45f13e2df72a4cb4dc875942e95775198db85c/components/mbedtls/esp_crt_bundle/cacrt_all.pem

# Compile 'blink'
cp -pr  /home/esp/idf/examples/get-started/blink  /home/esp/blink/
cd /home/esp/blink
. /home/esp/idf/export.sh
idf.py  set-target  esp32s2
idf.py build

However, the author of TinyUSB (@hathach) has told me that TinyUSB does not (and will not in the forseeable future) do what I need, so I need to use v4.4 of the IDF.

If I erase everything (and clear the environment) ...and repeat all the above steps using -b release/v4.4, the set-target command fails with:

~/blink $ idf.py  set-target  esp32s2

The same error happens if I use master or 4.4-dev branches, or if I use git to switch branches from 4.3.1 (as per the official docs) ...IE. 4.3.1 is the only version I can get to work - and I need v4.4 for the native USB support!

I'm out of ideas! Can anybody help please?

Thanks,
BC

Hello @csBlueChip

I don't get the error you are reporting with either master or release/v4.4. Here are the steps I use on Ubuntu 20.04 after deleting .espressif and esp directories (e.g. fresh install):

mkdir esp
cd esp
git clone -b release/v4.4 --recursive https://github.com/espressif/esp-idf.git
cd esp-idf
./install.sh
. ./export.sh
cd ..
cp -r esp-idf/examples/get-started/blink .
cd blink
idf.py set-target esp32s2
idf.py build

Hopefully this can shed some light on the issue you are seeing.

Thanks
Felix

P.S. Have you verified there is enough free space on your drive?

csBlueChip · 2021-11-10T00:29:00Z

@felmue

Felix. Thank You. Your success has led me to the source of my problem!

I pasted your exact commands to a "clean" user, and got the same problem (again) ...Then I repeated the exercise on an x86 Debian VM! ...Success!

It seems the source of the problem is that I have been using a Raspberry Pi 4 as my μC dev box ...release/v4.4 DOES work on x86/Debian; and does NOT work Pi4/Raspbian.

I'm not sure if you are the right person to ask this question, but: Is IDF v4.4 expected to work on a Pi4? ...Should I change the title of this Issue? Or start another? Or <other please specify>? ...Either way I offer my help to test any potential fixes.

On the bright side, Thank You for prompting me to realise the issue and find a functional workaround.

BC

felmue · 2021-11-10T07:00:56Z

Hello @csBlueChip

Thank you for your feedback. Unfortunately I don't know it IDF v4.4 is supposed to work on a Pi4 at this point in time and I don't posses a Pi4 so I cannot test myself. So yes, I'd suggest you change the title to indicate the issue is in conjunction with the Pi4. Hopefully somebody with better knowledge than me can help you figuring out what's causing the issue on the Pi4.

Thanks
Felix

Do you have any update on this issue?

Hi,

I'm experiencing the same issue. I thought I'd mention that if instead of using . export.sh I directly execute ~/.espressif/tools/xtensa-esp32-elf/esp-2021r2-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc -c foo.c -o foo then the compiler has no problem producing a binary executable. However, every attempt at compiling anything via idf.py fails with the same error reported by @csBlueChip above.

If there's something I can do to narrow this issue down and help you debug it, please let me know.

igrr · 2022-01-07T11:27:32Z

Just for info I did install version 4.3 which is working fine

will-emmerson · 2022-01-13T12:36:33Z

I have the same problem and had to go back to v4.3.1 (esp-2021r1-8.4.0) to fix it as v.4.3.2 (stable) uses the newer compiler.

phucng · 2022-01-15T05:12:27Z

I confirm that v4.3.1 (esp-2021r1-8.4.0) works on a Raspberry Pi 3 running Debian 11 (bullseye), while v4.3.2 (stable, uses esp-2021r2-8.4.0) doesn't work and yields the same issue as above.

Edit: there is no file named liblto_plugin.so in ~/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0. This file seems to be a new dependency in esp-2021r2-8.4.0 (which has liblto_plugin.so but still doesn't work.)

RSC-Games · 2022-02-10T19:03:11Z

I also confirm that v4.3.1 (esp-2021r1-8.4.0) works on Raspberry Pi 4 (2 GB model) with Raspberry Pi OS 32 bit (based on Debian 11). However, IDF v4.4 and v4.3.1 do NOT work, for the same issue as described as OP. I also investigated whether said file was present and it was.

fivdi · 2022-02-10T20:24:41Z

My heart goes out to all those waiting for this issue to be fixed. I have shed many a tear and wept daily since discovering this unfortunate problem. This issue is the source of persistent pain and great suffering and it will be a day of great joy and celebration when the issue is resolved.

fivdi · 2022-02-11T00:21:37Z

All the weeping due to this unfortunate issue resulted me having a chronic dehydration condition. However, what I have discovered is that ESP-IDF v4.4 and gcc do appear to work as expected for the ESP32 on a Raspberry Pi 4 if the 64-bit version of Raspberry Pi OS is used. Up until now I had been using the 32-bit version of Raspberry Pi OS as the 64-bit version was still in beta. This is no longer the case and the first non-beta 64-bit version of Raspberry Pi OS was released recently so I gave it a try.

Raspberry Pi OS 64-bit is being used:

So I am now happy 😄

I guess it's only the 32-bit Xtensa compilers that are broken the 64-bit compilers appear to work.

phucng · 2022-02-14T21:20:46Z

Thank @fivdi, for cheering and guiding us through these dark times. The latest version also works on my Pi after moving to the 64-bit Raspberry PI OS.

However, many of us cannot ditch the 32-bit OS and reinstall everything, at least until their next holiday. Some even have to stay 32-bit for compatibility. I hope that this issue will not be closed until addressed.

zikalino · 2022-02-24T16:01:23Z

all, the fix for this issue should be available in master soon, i will keep an eye on updates, and post more information soon

csBlueChip · 2022-04-03T16:47:10Z

Is there any more information available yet?

antmak · 2022-04-04T02:00:41Z

@csBlueChip We are on our way to get a new release of the toolchain. It is a big release with updating GCC and newlib versions. There is a chance to get a fix for the issue too

csBlueChip · 2022-04-07T10:17:16Z

Thank you. After 3 years of waiting, it is good to know that Espressif are "on their way" to releasing a devkit which will unlock the USB features of the chip, and there is "a chance" that it will work :)

RSC-Games · 2022-05-25T16:12:58Z

Any new updates on this? I installed 64 bit RPi OS recently, but I have yet to migrate my whole toolchain (which is based on a modified MicroPython codebase). I would like to update to IDF 4.4 (for ESP32 S3 support), but I am unable. I have a working executable generated from IDF 4.2.0, but I would prefer to use IDF 4.4.

antmak · 2022-05-30T09:17:05Z

Hi @RSC-Games ! The new toolchain with ARM*@linux fixes will come to master branch already on these days. Also the fixes will be ported to v4.4, but I'm not sure about ETA

MMucka · 2022-06-13T13:58:21Z

Hi, I have got also this problem on v4.4 with Raspberry Pi 4.
As I read, the v4.4. should be supported on Raspberry Pi 4, but it is still not.
Can you please keep this issue open until the fix will be available?

antmak · 2022-06-13T14:16:02Z

@MMucka right, for v4.4 we can open this

MMucka · 2022-06-13T14:20:31Z

What I have done:

cd ~/esp/esp-idf
git fetch
git checkout remotes/origin/release/v4.4
git submodule update --init --recursive
~/esp/esp-idf/install.sh esp32c3
. ~/esp/esp-idf/export.sh

but in tools, there is still old gcc

ls ~/.espressif/tools/riscv32-esp-elf
esp-2021r2-patch3-8.4.0

So I tried to apply changes from bf43076 for tools/tools.json and tools/toolchain_version.mk, but I have still problem to build simple test program.

RSC-Games · 2022-06-18T12:50:12Z

I have not verified that the latest commit works, because I migrated my toolchain to rpi 4 64 bit on Monday. I'll have to dig out my 32 bit sd card.

However, when I cloned IDF 5.0 it reported using GCC 11.2 and the compiler was esp-2022r1. I'm running IDF 4.4 and it reports using GCC 8.4 and esp-2021r2. This works for me, but then again I'm using 64 bit. If you can, then I would suggest using IDF 5.0, but for me, Micropython does not support IDF 5, so I'm stuck with 4.4.
