Got the same thing

[prubin100]

Has this been looked into yet? I am seeing the exact same error as OP when building for the Rock 5b (RK3588).

[flatmax]

I just did a test build and there were no failures. I got a full image compiled.

Can you confirm that you have all of the requirements installed ? Even python2 ?

[prubin100]

Thank you for following up.

I had not installed python2 as the readme indicated it was needed if building for the cm3 and rock3 derivatives. That said, I did install it, ran make clean and then re-ran make and hit the same error:

[flatmax]

What system are you building on ? OS ?

[prubin100]

I was originally using Ubuntu Desktop 20.04 LTS running under VMWare (under Windows 11). It had been some time since I had built that VM, so I made a fresh VM with Ubuntu Desktop 23.04. Unfortunately, I encountered the same error.

For the sake of completeness, with the fresh version of 23.04 installed, I performed the following from the /home/paul directory:

1. Cloned buildroot: git clone git://git.busybox.net/buildroot buildroot
2. Installed prerequisites: sudo apt-get install -y build-essential gcc g++ autoconf automake libtool bison flex gettext
   sudo apt-get install -y patch texinfo wget git gawk curl lzma bc quilt
3. Tried to install Python 2. This failed (E: Package 'python2' has no installation candidate): sudo apt install python2
4. Cloned the external buildroot tree: git clone https://github.com/flatmax/buildroot.rockchip.git buildroot.rockchip.ext
5. Ran the shell script for the Raxda Rock 5b board: source buildroot.rockchip.ext/setup.rock5b.sh /home/paul/buildroot
6. Made a buildroot dowloads directory: mkdir ../buildroot.dl
7. ran make

I ran the build without having python 2 since installing it on my 20.04 VM did not make a difference.

I did note the following prompts were not automatically answered by the build, but I do not believe my responses resulted in the build error(s) I am seeing:

Support Rockchip RK3528 (ROCKCHIP_RK3528) [N/y/?] (NEW)

Thanks again for the help; I must be doing something wrong.

[flatmax]

ok - a few issues here...

You need to checkout a particular version of buildroot. According to the readme :

git checkout 2022.05

Second of all I am pretty sure that the version of uboot sourced still required python2. Here are a few solution ideas for that problem :
1] Downgrade ubuntu to one which provides python2 as an installation candidate
2] Workout how to install the simplest implementation of python2 on your current ubuntu system.
3] Check if they have updated uboot yet to use python3 : https://github.com/radxa/u-boot/tree/stable-5.10-rock5 . If they have then bump the version of uboot to download in the board's config file.

[prubin100]

Once again, thank you for the follow up.

I actually had done the git checkout 2022.05, but did neglect to put it into my notes. Thank you for catching that.

I went all the way back to Ubuntu 18.04 and had not issues getting python installed. It did require sudo apt install python-minimal, but performing python2 -v shows 2,7.17 installed.

I did check the repo you reference and it does indeed still require python2, but there is a check in the make file to see if python2 is installed and an error is thrown if it is not found. I do not see that error, so I think there is a different issue.

The following is what I did under Ubuntu 18.04 and still I see the same error.

1. Cloned buildroot: git clone git://git.busybox.net/buildroot buildroot
2. Checkout for Rock 5b tested with version: git checkout 2022.05
3. Installed prerequisites: sudo apt-get install -y build-essential gcc g++ autoconf automake libtool bison flex gettext
4. sudo apt-get install -y patch texinfo wget git gawk curl lzma bc quilt
5. Install python2: sudo apt install python-minimal
6. Cloned the external buildroot tree: git clone https://github.com/flatmax/buildroot.rockchip.git buildroot.rockchip.ext
7. Ran the shell script for the Raxda Rock 5b board: source buildroot.rockchip.ext/setup.rock5b.sh /home/paul/buildroot
8. Made a buildroot dowloads directory: mkdir ../buildroot.dl
9. ran make

May I please ask what environment you used to run a test build?

[flatmax]

I've built this on various machines, ubuntu 22.04 and 22.10 for example.

[flatmax]

It is possible that pre-reqs are missing yes. When/if you find them, please let me know.

[akkusativk]

I got it working for the Rock 5b. Here are my steps:

1. I use the buildroot branch "2022.05.x", which corresponds to the tag 2022.05.3 (commit 4dc1fffca0)

However this caused uboot to break during build due to some code references which could not be resolved. I had a look and was confident, that the code which caused the error is not needed for the RK3588 (but for some other SoC), so I created the following patch.

2. Copy the following contents into a file "buildroot.rockchip.ext/patches.rk3588/uboot/004-rockchip-otp.patch":

Index: uboot-stable-5.10-rock5/arch/arm/mach-rockchip/rk3588/rk3588.c

 	if (ret) {

 		return ret;

Afterwards it did build and I could boot it.

@flatmax would you like that we change the recommended version in the readme to "2022.05.x"or tag "2022.05.3" and add the patch to your repo? If so (I have actually never done this before) how should I do it? May I create a pull request?

[akkusativk]

@edwardzhou the actual reason why I tried buildroot version "2022.05.x" aka. tag "2022.05.3", is, that I also got some error during compilation before. I however don't recall it. But it might have been the same as you. After changing I then ran into the uboot issue, hence I created the abovementioned patch.

[akkusativk]

@prubin100 I just realize, that my patch (at first glance) corresponds to the error you report. Maybe just try integrating my patch - it might work.

[prubin100]

Hi @akkusativk. Thank you for spending time on this issue and posting your findings. Curiously, I was still not able to build following your suggestion. I still receive the same error. It's as if the "buildroot.rockchip.ext/patches.rk3588/uboot/004-rockchip-otp.patch" file is being ignored - the lines of code it seeks to comment out look to still be compiling and thus the same error. I am not an expert on buildroot, but it does seem like the patch file should have been processed by virtue of its location.

[bmclapham1973]

@flatmax I am also unable to successfully compile. I have the same result as @prubin100. The only difference in my setup is that I attempted it on Debian 12. Thoughts?

@akkusativk Applying the patch you described had no impact on my result.

[flatmax]

@prubin100 @bmclapham1973 please describe your issues here. What is the error you face ?

Here are my steps (switch for your correct paths below) :

source ~/temp/buildroot.rockchip/setup.rock5b.sh /home/name.unencrypted/buildroot.rk3588/
make distclean
git checkout 2022.05
source ~/temp/buildroot.rockchip/setup.rock5b.sh /home/name.unencrypted/buildroot.rk3588/
make

@flatmax I got the same error after following your same steps:

source ~/temp/buildroot.rockchip/setup.rock5b.sh /home/name.unencrypted/buildroot.rk3588/
make distclean
git checkout 2022.05
source ~/temp/buildroot.rockchip/setup.rock5b.sh /home/name.unencrypted/buildroot.rk3588/
make

[flatmax]

can you confirm you have python2 on your system ?

what is the output of python2 when you execute it ?!

[bmclapham1973]

@flatmax
bash: python2: command not found

[prubin100]

@flatmax I also tried the additional steps you recommended. I did not get the error I had previously seen and which @bmclapham1973 is now seeing but instead a new error. Below is the section of the output leading up to and including the build error. It's odd, it can't find a file related to openssl but clearly in a section related to the rk3588 when the error occurs.

For what it's worth I had previously reverted (per my comments above) to Ubuntu 18.04 and installed python2, but doing so never helped with the error I had been seeing and which @bmclapham1973 is seeing now.

I am going to make clean and try the build again to see if it was a fluke or recurs.

please install python2 and try again. It should work.
You see the problem is that the uboot version Radxa are using requires python2 and possibly python3. I believe Radxa are putting in changes to remove python2 dependencies - but we can integrate those changes later.

[flatmax]

@prubin100 that is a lot of information you are printing - I can't see anything I need there. Is it trying to compile Linux ?

I am planning to install python 2.7 from source since it's not available via apt anymore. Do you have another suggestion for installing python2 on Debian 12?

That was a problem for me as well - I can't remember how I solved it. Give it a go - it should be ok.

Based on the following two lines it does look to me like it is trying to compile Linux:

linux 52f51a2b5ba178f331af62260d2da86d7472c14b Configuring
linux 52f51a2b5ba178f331af62260d2da86d7472c14b Building

The two lines just prior to the compilation error are what made me think it is related to the RK3358 code:

DTCO arch/arm64/boot/dts/rockchip/overlay/rk3588-pwm3-m1.dtbo
HOSTCC scripts/extract-cert

ok - I am a little unsure why it is having trouble.
What host system are you building on ?
Are you sure you have checked out the correct version of buildroot ?

@prubin100 do you still have the issue, that the patch is not applied? If so, maybe buildroot does not apply the patch, because it thinks, that all patches for the package were already applied. Buildroot uses so called "stamp files" (e.g. '.stamp_downloaded', '.stamp_extracted', '.stamp_patched') to monitor the "progress" of packages, e.g., whether the patches for some packes were already applied or not. If the stamp file ist present, then a new compilation will cause the particular step to NOT be executed again. I.e., if there is already a '.stamp_patched' in your uboot BUILD folder (i.e., buildroot/output/build/uboot-versionXYZ/.stamp_patched), then no patches will be applied, if you rebuild. This then also means, that any new patch you add afterwards will not be applied.

I know 3 things you can do:

• clean the whole buildroot and rebuild everything by e.g., executing make distclean - this will take lots of time unnecessary
• clean only the uboot BUILD folder by manually removing it, e.g., by executing rm -rd buildroot/output/build/uboot-<version>
• use buildroot command to clean the build folder, i.e., make uboot-dirclean

I like the last option best. Afterwards you could try to first only rebuild uboot, by using make uboot-rebuild. Then you could see, whether the patch gets applied and whether it fixes your rockchip-uboot issues.

For more info about how to rebuild packages in buildroot, see here: https://buildroot.org/downloads/manual/manual.html#rebuild-pkg

I hope this helps :)

@prubin100 regarding the other issue "fatal error: openssl/bio.h: No such file or directory", I had the same one recently. For me, installing libssl-dev did the trick, like described here: TinkerBoard/debian_kernel#26

@prubin100 @bmclapham1973 what you could also try to do just as a test: You could try to just manually apply the changes of my patch to the source file. Therefore you would have to open /app/buildroot/buildroot/output/build/uboot-stable-5.10-rock5/arch/arm/mach-rockchip/rk3588/rk3588.c, go to line 1164 and then manually apply the changes of my patch. It should then work. However, beware that

a) the patch is then not used by buildroot, else there will be an error, because the patch cannot be properly applied once you already made the change manually
b) the build will only work as long as the uboot build folder is then preserved in the patched state. After a make distclean or a make uboot-dirclean the fix will of course be lost again
