Dependency Conflict During Milvus Compilation

Symptom

A compilation error is reported, indicating that the dependency version conflicts during dependency installation.

ERROR: Conflict in opentelemetry-cpp/1.8.1.1@milvus/dev:
'opentelemetry-cpp/1.8.1.1@milvus/dev' requires 'thrift/0.17.0' while 'arrow/15.0.0' requires 'thrift/0.20.0'.
To fix this conflict you need to override the package 'thrift' in your root package.

Key Process and Cause Analysis

Two components depend on different thrift versions. You can forcibly specify a version that can be used by both of the two components.

Conclusion and Solution

Find the ~/milvus/internal/core/conanfile.py file in the compilation path, add the dependencies having conflicts to the configure function of a class inherited from ConanFile, and overwrite thrift they use.

from conans import ConanFile

class MilvusConan(ConanFile):
    def configure(self):
        if self.settings.arch not in ("x86_64", "x86"):
            del self.options["folly"].use_sse4_2
        if self.settings.os == "Macos":
            # By default abseil use static link but can not be compatible with macos X86
            self.options["abseil"].shared = True
            self.options["arrow"].with_jemalloc = False
        # Forcibly use the thrift of a specific version.
        self.requires("thrift/0.20.0", override=True)
