在mac下，make遇错

[luckypoem]

hi。

我运行make,显示： ... [ 67%] Built target fmt Scanning dependencies of target vpncore [ 67%] Linking CXX static library libvpncore.a ar: no archive members specified usage: ar -d [-TLsv] archive file ... ar -m [-TLsv] archive file ... ar -m [-abiTLsv] position archive file ... ar -p [-TLsv] archive [file ...] ar -q [-cTLsv] archive file ... ar -r [-cuTLsv] archive file ... ar -r [-abciuTLsv] position archive file ... ar -t [-TLsv] archive [file ...] ar -x [-ouTLsv] archive [file ...] make[2]: *** [vpncore/libvpncore.a] Error 1 make[1]: *** [vpncore/CMakeFiles/vpncore.dir/all] Error 2 make: *** [all] Error 2 yudeMacBook-Air:avpn-master brite$ ls CMakeCache.txt README.md third_party CMakeFiles avpn tun2socks.service CMakeLists.txt bin tun2socks.service.in LICENSE cmake vpncore Makefile cmake_install.cmake yudeMacBook-Air:avpn-master brite$ ls bin yudeMacBook-Air:avpn-master brite$

如何解决？

xcode 没安装全。

@microcai 你好。可提供mac上的可执行文件下载吗

@microcai 你说“xcode 没安装全。”， 怎样才算xcode安装全了？
