WINDOWS/cygwin编译lame出错：error: ‘_O_BINARY‘ undeclared

Posted 2022-10-24 柳鲲鹏

• 具体错误：

lametime.c: In function 'lame_set_stream_binary_mode':
lametime.c:139:25: error: '_O_BINARY' undeclared (first use in this function); did you mean 'O_BINARY'?
     setmode(fileno(fp), _O_BINARY);

• 解决办法

打开出错文件 vi ./frontend/lametime.c
找到这一行：

#elif defined __CYGWIN

修改下面一行：

setmod(fileno(fp), _O_BINARY);
为
setmod(fileno(fp), O_BINARY);
