Question

Qt 发布程序时出错 Debug时没有错误 Release时出现错误

typedef struct tag
{

unsigned short int group;

unsigned short int element;

char vr[3];

unsigned int length;

char *vf;
}TAG;

TAG file_meta_info[K] = {

{ 0x0002, 0x0000, "UL", 4, (char *)&glen },

{ 0x0002, 0x0001, "OB", 2, "01" },

{ 0x0002, 0x0002, "UI", 0, NULL },

{ 0x0002, 0x0003, "UI", 0, NULL },

{ 0x0002, 0x0010, "UI", 0, NULL },

{ 0x0002, 0x0012, "UI", 0, NULL },

{ 0x0002, 0x0013, "SH", 0, NULL } };

显示出错在最后一行，不过把最后一行注释掉之后仍然出错，而且还在最后一行。
error: C2440: 'initializing' : cannot convert from 'const char [3]' to 'char *'
Conversion from string literal loses const qualifier (see /Zc:strictStrings)

Answer 1

Debug下与Release pro下配置不同吧，看起来release下配置了/Zc:strictStrings这个，禁用字符串文本类型转换

追问

请问能在什么地方改了吗，之前我没有改动过这个选项，应该还是默认的

Answer 2

在QMAKE_CXXFLAGS_RELEASE += -Zc:strictStrings-
添加这个选项，就可以了
