+Subject: [PATCH] configure.ac: fix grpc build
+
+Similar to the previous "configure.ac: fix grpc build" commit:
+Google bumped it's compiler requirements again [1], hence the c++ version needs to be adjusted to c++17 to be able to build with the latest grpc versions.

Re: [Buildroot] [PATCH 1/4] package/collectd: fix build with grpc

Could you provide more details on which commit introduced this
regression, and a defconfig that exhibits the build failure?

Indeed, I tried:

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_COLLECTD=y
# BR2_PACKAGE_COLLECTD_LOGFILE is not set
# BR2_PACKAGE_COLLECTD_SYSLOG is not set
BR2_PACKAGE_COLLECTD_GRPC=y
# BR2_TARGET_ROOTFS_TAR is not set

And it builds just fine. I believe the fix is correct, but the commit
log doesn't provide enough details, which are needed to understand
whether this fix needs to be backported to one of our stable branches.

Thanks a lot!

Thomas

the "breakage" is introduced in the series which this commit is part of when bumping grpc & abseil. So maybe the title could have been better. I just oriented on the title of the previous commit which bumped collectd to C++14 and is also named so in the collectd repo.

Regards,
Michael

So you mean that in the current master there is no breakage, and it's
only the fact that your series is bumping abseil and grpc that some
breakage will be introduced, and that you therefore fix before the
version bumps?

correct. This is why it's part of the series bumping abseil/protobuf/grpc.
I just reordered the series before sending and missed to reword this commit
to be more intuitive. I can resend this next year with reworked wording
when I'm back at my working setup.

Michael
