float point support not loaded

    这几天用VC2010编写了一个小程序，拷贝到另外一台计算机时候出现 float point support not loaded 的错误，搜索了下好像是float类型的数据未初始化，导致运行时未链接浮点库。float data[8];

sscanf(str,"%02X",data[i]);   将float data[8]; 改为float data[8] = {0}；即可。或增加一个float参数函数，或为一个浮点数赋值，注意不要被优化掉。

floating-point support not loaded

The necessary floating-point library was not linked.

To fix by checking the following possible causes

1.
The program was compiled or linked with an option, such as /FPi87, that requires a coprocessor, but the program was run on a machine that did not have a coprocessor installed.

2.
A format string for a printf_s or scanf_s function contained a floating-point format specification and the program did not contain any floating-point values or variables.

3.
The compiler minimizes a program's size by loading floating-point support only when necessary.The compiler cannot detect floating-point format specifications in format strings, so it does not load the necessary floating-point routines.

4.
Use a floating-point argument to correspond to the floating-point format specification, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded.

5.
In a mixed-language program, a C library was specified before a FORTRAN library when the program was linked. Relink and specify the C library last.

错误消息

未加载浮点支持

 

未链接必需的浮点库。

通过检查下面的可能原因进行修复

1. 该程序通过选项（如 /FPi87，该选项要求有协处理器）被编译或链接，但该程序运行在一台未安装协处理器的计算机上。

2. printf_s 或 scanf_s 函数的格式字符串包含浮点格式规范，而该程序不包含任何浮点值或变量。

3. 编译器仅当必要时才通过加载浮点支持以最小化程序大小。编译器无法检测到格式字符串中的浮点格式规范，因此编译器未加载必要的浮点例程。

4. 使用浮点参数以符合浮点格式规范，或在程序的其他地方执行浮点赋值。该操作将导致加载浮点支持。

5. 在由混合语言编写的程序中，当程序进行链接时在 FORTRAN 库之前指定了 C 库。重新链接并最后指定 C 库。
