I am learning how to compile custom Linux using Yocto. Currently I'm using Yocto Project 2.4 and I have added Python3 to the build. However, Python 3.5.2 was installed and I am interested in a newer version (e.g., Python 3.8.5). The reason I'm using this Yocto Project version is because I'm trying to compile a specific Linux version for Toradex modules.

So, how can I backport a newer Python version to my build? The only information I've found is in this forum post, that mentions something about copying python3_x.x.x.bb and python3.inc files, but it is not clear to me.

  • It seems Toradex does not provide BSPs for Yocto 2.3 https://developer.toradex.com/knowledge-base/board-support-package/openembedded-core#Versions_and_SourceCode, are you sure that is the correct version? Did you also consider using a newer BSP with the kernel version you need? – lgraba Jan 14 '21 at 12:17
  • Hi. Sorry, I meant 2.4 (I have corrected the error). I will try Yocto 3.1. Anyway, the backporting question still stands. – Cristian M Jan 14 '21 at 12:33

We saw your post at Toradex Community.

We are analyzing your issue because the root cause of your problem is because your newer python3 recipe requires "virtual/crypt", while the previous just had:

python3_3.5.3.bb:3:DEPENDS = "python3-native libffi bzip2 db gdbm openssl readline sqlite3 zlib virtual/libintl xz"

I'm discussing with my colleagues what could be a good approach for this case.

In the meantime, I strongly suggest you move forward to BSP 3.0.
