如何解决对 boost asio
我在使用 opt 和 Bazel 构建 boost 模式时遇到问题。这是我的错误。

我的构建文件如下所示。
cc_binary(
name = "denarii_wallet_cli",srcs = [
"simplewallet.cpp","simplewallet.h",],linkopts = [
"-lssl","-lcrypto","-ldl","-lpthread","-lboost_system","-lboost_thread",deps = [
"//contrib/epee","//src:cncrypto","//src:common","//src:cryptonote_core","//src:cryptonote_protocol","//src:rpc_base","//src:version","//src:wallet","//src/mnemonics","@boost//:asio","@boost//:chrono","@boost//:filesystem","@boost//:locale","@boost//:program_options","@boost//:system","@boost//:thread","@liblzma","@libreadline","@openssl//:libcrypto","@openssl//:libssl","@qrcodegen",)
它在 dbg 和 fastbuild 模式下构建良好。所以我不知道为什么这不起作用。如果人们有其他问题，我可以提供更多信息，我只是不知道该提供什么:)
我还看到了其他类似的问题，例如：undefined reference to `boost::system::generic_category()' when adding boost/asio
解决方法
对于 https://github.com/nelhage/rules_boost，您需要包含“@boost//:asio_ssl”才能使其正常工作。 :) 并在上述问题中包含链接器标志。
