C++ Windows 错误加载共享库

Question

我收到以下错误。我在使用 bazel 4.0 和 msys2 的 Windows 10 上。

C:/Users/katso/Documents/Github/KeirosPublic/bazel-out/x64_windows-opt-exec-2B5CBBC6/bin/external/com_google_protobuf/protoc.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

当我运行这个命令时

bazel-out/x64_windows-opt-exec-2B5CBBC6/bin/external/com_google_protobuf/protoc.exe --proto_path=bazel-out/x64_windows-fastbuild/bin/external/com_google_protobuf/_virtual_imports/timestamp_proto --java_out=bazel-out/x64_windows-fastbuild/bin/Security/Proto/validity_period_proto-speed-src.jar -ISecurity/Proto/validity_period.proto=Security/Proto/validity_period.proto -Igoogle/protobuf/timestamp.proto=bazel-out/x64_windows-fastbuild/bin/external/com_google_protobuf/_virtual_imports/timestamp_proto/google/protobuf/timestamp.proto --direct_dependencies google/protobuf/timestamp.proto:Security/Proto/validity_period.proto

重新创建它的简单方法如下

如果您运行此命令的某个版本，您将获得可以运行以重现此命令的命令。

bazel build :all --compiler=mingw-gcc --verbose_failures

如果您遗漏了任何其他可能有用的信息，请告诉我。这基本上破坏了 bazel 的 mingw 编译器。我不能使用普通的 MSVC，因为我的依赖项只能在 mingw 中构建。

我跑了ldd protoc.exe 并得到了

        ntdll.dll => /c/Windows/SYSTEM32/ntdll.dll (0x7ffcfa410000)
        KERNEL32.DLL => /c/Windows/System32/KERNEL32.DLL (0x7ffcf89f0000)
        KERNELBASE.dll => /c/Windows/System32/KERNELBASE.dll (0x7ffcf7f70000)
        msvcrt.dll => /c/Windows/System32/msvcrt.dll (0x7ffcf86e0000)

这毫无意义，因为我的PATH 是/usr/local/bin:/usr/bin:/bin:/opt/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:C:/Users/katso/Documents/Github/KeirosPublic/bazel-out/x64_windows-opt-exec-2B5CBBC6/bin/external/com_google_protobuf/:/c/Users/katso/AppData/Local/Microsoft/WindowsApps:/c/Users/katso/Documents/Github/KeirosPublic/bazel-out/x64_windows-opt-exec-2B5CBBC6/bin/external/com_google_protobuf/:/c/Windows/SYSTEM32

Answer 1

我通过将以下标志传递给编译器解决了这个问题

--copt="-static-libgcc" 和 --copt="-static-libstdc++" 和 --copt="-static"
