C++ twsapi IBKR c++；API安装

我从网站下载了这个项目

安装中说明要执行以下操作：

 ./configure
 make
 make install

当我调用

make

时，我收到以下错误：

/Library/Developer/CommandLineTools/usr/bin/ranlib: file: .libs/libtwsapi.a(libtwsapi_la-StdAfx.o) has no symbols
/Library/Developer/CommandLineTools/usr/bin/ranlib: file: .libs/libtwsapi.a(libtwsapi_la-StdAfx.o) has no symbols
./gen_twsapi_config_h config.h ./API_VersionNum.txt \
        ./cpp/client/EClient.h > twsapi_config.h.tmp \
        && mv twsapi_config.h.tmp twsapi_config.h
/bin/sh: ./gen_twsapi_config_h: Permission denied
make[2]: *** [twsapi_config.h] Error 126
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

如何处理

谢谢
