针对你提出的编译错误 error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast],这里有一些详细的步骤和解释来帮助你解决这个问题: 1. 理解错误信息 错误信息表明,你尝试将一个整数类型转换为指针类型,但这两个类型的大小不匹配。这通常发生在64位系统上,其中指针通常是64位的,而...
这没啥，这里说的pointer truncation就是像这样的代码：intptrtoint(void*ptr){return(int)ptr;} 这样...
D:/api/library/libwebsockets-3.2.3/lib/core-net/vhost.c:732:21: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 732 | if (vh->log_fd == (int)LWS_INVALID_FILE) { | ^ D:/api/library/libwebsockets-3.2.3/lib/core-net/vhost.c:745:16: error:...
我也遇到过同样的问题，将int改为void，然后将原函数中的return 0；这句话删掉。一切就OK了。
error: cast from ‘char*’ to ‘int’ loses precision 最后google了一下,找到了答案:http://stackoverflow.com/questions/1640423/error-cast-from-void-to-int-loses-precision 应该将(int)addrCom 改为(long)addrCom即可 解释: 因为我编译的系统为linux64位,其指针类型和long型大小相等(8B)而与int型4B,...
xxx.h:117:59: error: cast from ‘int32_t*’ {aka ‘int*’} to ‘int’ loses precision [-fpermissive] int m_MinValidLen = (int)(&(((DataOnAir *)0)->rx_ts_s)); 报错原因: 该这里是因为基于Linux内核的64位系统上指针类型占用8个字节,而int类型占用4个字节,所以会出现loses precision。
