carthage生成mailcore2.framework失败

[wenjunos]

你好，我的Xcode12.1使用carthage生成mailcore2.framework会失败：
Build Failed
Task failed with exit code 65:
/usr/bin/xcrun xcodebuild -project /Users/jack/Downloads/ZGMailbox-master/Carthage/Checkouts/mailcore2/build-mac/mailcore2.xcodeproj -scheme mailcore\ ios -configuration Release -derivedDataPath /Users/jack/Library/Caches/org.carthage.CarthageKit/DerivedData/12.1_12A7403/mailcore2/b2afd63da828748905f97dc3146e562781b97c7d -sdk iphoneos ONLY_ACTIVE_ARCH=NO BITCODE_GENERATION_MODE=bitcode CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY= CARTHAGE=YES archive -archivePath /var/folders/hd/r658qqc972196cx3yrx4z9h80000gp/T/mailcore2 SKIP_INSTALL=YES GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=NO CLANG_ENABLE_CODE_COVERAGE=NO STRIP_INSTALLED_PRODUCT=NO (launched in /Users/jack/Downloads/ZGMailbox-master/Carthage/Checkouts/mailcore2)

This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/hd/r658qqc972196cx3yrx4z9h80000gp/T/carthage-xcodebuild.vCyl88.log

请问这个要怎么解决呢？由于我的项目不能使用cocoapod，只能选择carthage和手动导入mailcore2，手动又会报：'libetpan/libetpan.h' file not found的错，请问你有遇到过吗？希望能为我提供一些帮助呢，万分感谢！

同样的问题，看build.log 是不认macOS系统的autoconf，重装了autoconf

删掉 carthage 依赖的，直接用pod依赖 mailcore就正常。
