I was able to build 26.04.1 and it does run. I had to apply a couple of patches based on github issues: https://github.com/ElementsProject/lightning/issues/9106 https://github.com/ElementsProject/lightning/issues/9074

Patch 1 on core-lightning/common/wireaddr.c:


-       char *portcolon;
+       const char *portcolon;

        if (strstarts(arg, "[")) {
-               char *end = strchr(arg, ']');
+               const char *end = strchr(arg, ']');
                if (!end)
                        return false;
                /* Copy inside [] */

Patch 2 on core-lightning/configure:


 CONFIGURATOR=ccan/tools/configurator/configurator
 CONFIG_VAR_FILE=config.vars
 CONFIG_HEADER=ccan/config.h
-BASE_WARNFLAGS="-Wall -Wundef -Wmissing-prototypes -Wmissing-declarations -Wstrict-prototypes -Wold-style-definition -Werror"
+BASE_WARNFLAGS="-Wall -Wundef -Wmissing-prototypes -Wmissing-declarations -Wstrict-prototypes -Wold-style-definition"

 OS=$(uname -s)
 ARCH=$(uname -m)

These issues should be resolved in 26.06 according to the developers if you don't want to bother with the patching.

I had to start up lightningd from the command line and NOT use systemctl otherwise it would time out. Perhaps the database upgrade took a long time. It did take a very long time to startup, perhaps 10 minutes or more. After the first startup I can run it with systemctl and it starts up quickly.

v26.04 does not build, https://github.com/ElementsProject/lightning/issues/9074.

Thanks for the explanation. I reverted my last commit to include your temporary fix.

@Spixmaster I believe the root cause is a package versioning mismatch between protoc from protobuf and the plugin from python-grpcio-tools. The plugin only supports up to "Editions 2023" (open issue upstream).

That said, building this is is a packaging mismatch between what Arch is providing and what lightning's pyproject.toml pins. Arch is on python-grpcio-tools 1.76.0, but lightning has generated code created using grpcio-tools 1.75.1.

The --experimental-editions patch I provided before was a way to work around this. I'm not sure of any other solutions besides creating python-grpcio-tools-1.75 and protobuf-31.1 in the AUR.

This error is still present for me, https://github.com/ElementsProject/lightning/issues/8532.

@cotsuka - thank you for your work on this. I upgraded and everything is working correctly.

I've been running with the updated PKGBUILD with no issues.

EDIT: My guess as to the 40 MB increase in size is due to the --experimental-editions flag, which means gRPC needs to be built with additional syntax/wire protocol support.

Spixmaster commented on 2025-10-13 06:24 (UTC)

Currently, I do not need to use this software.

bitcoinlizard commented on 2025-10-13 02:15 (UTC)

@cotsuka and @Spinxmaster - are you using this current version of the PKGBUILD following the changes by Cotsuka? I was able to successfully build it. The upgrade size was over 40 MB which seemed quite large. I haven't tried to install it and run it yet.

The related github issue seems about both the build process AND the plyn python modules so I was confused.

cotsuka commented on 2025-10-08 16:10 (UTC)

Works on my end.
