experimental_allow_proto3_optional was not set

[zixijian]

I build it on my Android phone chroot container

my env:
ubuntu-22.04-arm64
gcc 12.3 g++ 12.3
protoc 3.12.4

libfmt must compile alone,otherwise could not find std.h.
https://github.com/fmtlib/fmt

apt-get install -yq \
cmake git golang libbrotli-dev \
libgtest-dev liblz4-dev libpcre2-dev libprotobuf-dev libunwind-dev \
libzstd-dev pkg-config protobuf-compiler ninja-build xz-utils \
libusb-1.0-0-dev libbsd-dev 

make -j8 -lbsd

Then i got an error:

[ 93%] Running cpp protocol buffer compiler on adb/proto/app_processes.proto

Should I compile every package or upgrade ubuntu to 24.04?

It is recommended to publish common precompiled packages for arm64 or amd64 using github action.

[anatol]

try compilation flag -D ANDROID_TOOLS_USE_BUNDLED_LIBUSB

[zixijian]

@anatol Thanks a lot.
I finally switched the tag 34.0.5 through.
What should i do,if I dont want to compile adb and fastboot?

[Biswa96]

Try with Ubuntu 24.04. I had similar issue with older Ubuntu version, see 7cb4b93 commit.
