Macos install failed

[dongshimou]

在master分支上 make install出现下面这样的日志,然后g++ -std=c++11 xxx.cpp -llibgo会抱找不到引用的错.

在3.0分支make install也会出现这种错误.但是在编译的时候又是另外的错误了.

g++ -std=c++1z main.cpp -llibgo

请用master分支。

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: /usr/local/lib/liblibgo.a(epoll_reactor.cpp.o) has no symbols 这个错误可以无视

你说的“找不到引用的错”可以贴出来看看吗
