From e94dda42c50ec72bb3c3ea96c7b7761cbe219d3d Mon Sep 17 00:00:00 2001 From: Nils Wireklint Date: Mon, 1 Jul 2024 15:38:50 +0200 Subject: [PATCH] Use prebuilt protoc toolchain This downloads a prebuilt protoc binary and uses that through regular toolchain resolution (with the incompatible flag). This increases build speed and removes the many compiler warnings that pop-up during compilation of protoc sources. And more importantly works better on Windows. Where for some reason the protoc compilation fails from an external module: gits/bb-deployments $ bazel build \ --override_module protobuf=../protobuf \ @protobuf//src/google/protobuf:timestamp_proto ERROR: C:/tmp/eprbnvuo/external/protobuf~/src/google/protobuf/compiler/java/BUILD.bazel:99:11: Compiling src/google/protobuf/compiler/java/context.cc [for tool] failed: undeclared inclusion(s) in rule '@@protobuf~//src/google/protobuf/compiler/java:java': this rule is missing dependency declarations for the following files included by 'src/google/protobuf/compiler/java/context.cc': 'bazel-out/x64_windows-opt-exec-ST-d57f47055a04/bin/external/protobuf~/src/google/protobuf/compiler/java/_virtual_includes/java/google/protobuf/compiler/java/context.h' Whereas it does work when building from its own checkout: ~/gits/protobuf $ bazel build \ //src/google/protobuf:timestamp_proto Target //src/google/protobuf:timestamp_proto up-to-date: bazel-bin/src/google/protobuf/timestamp_proto-descriptor-set.proto.bin INFO: Build completed successfully, 1 total action --- .bazelrc | 2 ++ MODULE.bazel | 1 + MODULE.bazel.lock | 7 +++++-- 3 files changed, 8 insertions(+), 2 deletions(-) diff --git a/.bazelrc b/.bazelrc index 3752b49..fb54aa4 100644 --- a/.bazelrc +++ b/.bazelrc @@ -37,3 +37,5 @@ build:remote-ubuntu-22-04 --extra_execution_platforms=//tools/remote-toolchains: # When running bare executors on your own host machine. build:remote-local --config=remote-exec + +common --incompatible_enable_proto_toolchain_resolution diff --git a/MODULE.bazel b/MODULE.bazel index 7130709..3f338f0 100644 --- a/MODULE.bazel +++ b/MODULE.bazel @@ -22,6 +22,7 @@ bazel_dep(name = "rules_oci", version = "1.7.6") bazel_dep(name = "rules_pkg", version = "0.10.1") bazel_dep(name = "rules_proto", version = "6.0.2") bazel_dep(name = "toolchains_llvm", version = "1.0.0") +bazel_dep(name = "toolchains_protoc", version = "0.3.1") # # Workarounds 2026-06-27 # ERROR: in tag at https://bcr.bazel.build/modules/grpc-java/1.62.2/MODULE.bazel:89:15: no repository visible as '@com_google_protobuf_javalite' to the repository '@@grpc-java~', but referenced by label '@com_google_protobuf_javalite//:protobuf_javalite' in attribute 'target' of tag 'override'.
