I confirm that this works on OpenWrt :)

I actually started testing shortly after the PR was created.

Many thanks for the quick patch.

Christian Heimes  added the comment:

I have created a PR that adds a check for libuuid to configure and then uses 
configure variables in setup.py. Could you please try the patch in your build 
system?

Alexandru Ardelean  added the comment:

I've added Christian Heimes to this, mostly to help us get this further.
(i.e. to refer someone else here, that can help).

So, there is a fix for this in Buildroot's tree:

https://github.com/buildroot/buildroot/blob/76c7fed85f7a822663cf0c8828e7d282198d0803/package/python3/0030-Fix-cross-compiling-the-uuid-module.patch

I am porting this patch to OpenWrt.
And it seems to work as well.

I'd like to know how to proceed with this patch and submit it upstream.
I did not author this patch, so it may be tricky.
We may need to contact the original author?

Or would it be fine for me to open a PR and mention the original source/author?

[issue43158] uuid won't build when libuuid is installed in a non-standard place

[Larry Hastings]

New submission from Larry Hastings :

I'm building Python for a mildly-embedded ARM system.  The system is running 
Linux, but doesn't have a native toolchain installed.  So I'm building in a 
Docker container using a native toolchain (virtualizing the CPU).

The toolchain I'm given has a bunch of stuff preinstalled, but not 
"util-linux", so it doesn't have /usr/include/uuid/uuid.h or  
/usr/include/uuid.h .  I built and installed it myself in my PREFIX directory.  
But Python's build process has *two* bugs that prevented me from building the 
uuid module:

* configure doesn't look in PREFIX for uuid/uuid.h or uuid.h.  I assume it's 
only looking in /usr/include.  This means it doesn't define any of the 
HAVE_UUID_* defines.

* detect_uuid() in setup.py, which actually builds the module, *does* seem to 
check the prefix directory, but only for $PREFIX/uuid.h, not for 
$PREFIX/uuid/uuid.h.

I hacked both of these manually and was rewarded with the uuid module building 
and working fine on the embedded system.  So I assert this is a bug in Python's 
build process, if a minor one.
