编译Gamma的第三方软件scann-1.2.1时报错

[frederic89]

按照vearch和gamma编译说明和编译脚本，当运行到用bazel编译scann-1.2.1时出现如下报错，都指向com_google_protobuf这个内容：

ERROR: /root/.cache/bazel/_bazel_root/7125299c24cb2d7bde318ecca9ed5091/external/com_google_protobuf/BUILD:979:21: in proto_lang_toolchain rule @com_google_protobuf//:cc_toolchain: '@com_google_protobuf//:cc_toolchain' does not have mandatory provider 'ProtoInfo'.
ERROR: Analysis of target '//:build_pip_pkg' failed; build aborted: Analysis of target '@com_google_protobuf//:cc_toolchain' failed
INFO: Elapsed time: 0.270s
INFO: 0 processes.
FAILED: Build did NOT complete successfully (0 packages loaded, 0 targets conf
igured)

我试了这个网文的方法（https://zhuanlan.zhihu.com/p/488199658）
#bazel版本过高的话，会有如下错误： in proto_lang_toolchain rule @com_google_protobuf//:cc_toolchain: '@com_google_protobuf//:cc_toolchain' does not have mandatory provider 'ProtoInfo'. 可以加以下参数解决： bazel build ... --incompatible_blacklisted_protos_requires_proto_info=false
还是也不能修复编译问题，是不是WORKSPACE里的 https://github.com/bazelbuild/rules_cc 的版本或者com_google_protobuf使用github的tag版本有问题，也有网文说要修改类似内容的。我试验了改了这俩个几个版本，在bazel编译时还是出现failed ERROR。

Centos 7 ( MacOS Big Sur + 2.7 GHz 双核Intel Core i5 + Parallels Desktop) + bazel 4 + gcc 9.3.1+ clang 8

1. gcc 9 是利用了devtoolset-9安装的，环境通过source /opt/rh/devtoolset-9/enable激活
2. clang llvm8编译安装，PATH:/usr/local/clang/bin
3. Bazel 4 安装使用了：
   wget https://copr.fedorainfracloud.org/coprs/vbatts/bazel/repo/epel-7/vbatts-bazel-epel-7.rep --no-check-certificate
   mv vbatts-bazel-epel-7.rep /etc/yum.repos.d/
   cd /etc/yum.repos.d
   mv vbatts-bazel-epel-7.rep vbatts-bazel-epel-7.repo
   yum install -y bazel4

换用了bazel3无以上报错

[frederic89]

请问可以Pass的bazel编译版本是多少？

[zcdb]

我们内部使用的3.4.1

[frederic89]

jdk版本呢？ 谢谢

[zcdb]

jdk? 这不涉及jdk吧

[frederic89]

jdk? 这不涉及jdk吧

我手动装bazel 我看bazel需要安装对应版本的openjdk才能使用成功 查了下 好像bazel3不能用openjdk-8
https://blog.csdn.net/weixin_44278403/article/details/107449795 所以才来问一下咯

[frederic89]

bazel 3.4.1 + openjdk-11 + gcc 9.4(编译安装) + clang-8 环境编译scann不通过报错:
请再指教 @zcdb
(bazel 3.4.1 安装自 https://mirrors.huaweicloud.com/bazel/3.4.1/bazel-3.4.1-installer-linux-x86_64.sh
openjdk 安装自yum install)
(gcc+clang 在env的中配置
echo "export CC=clang" >> /etc/bashrc
# echo "export CC=/usr/bin/gcc" >> /etc/bashrc
echo "export CXX=clang++" >> /etc/bashrc
echo "export PATH=$PATH:/usr/local/clang/bin" >> /etc/bashrc)
