Question

我一直在尝试在Linux上编译一个Windows 64程序，MSVAR1.3，并且遇到了Linux和程序调用的头文件的问题。该计划要求：

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <math.h>
#ifdef __BORLANDC__
    #include <float.h>

如果我运行编译（在linux中使用gcc）并尝试使用-I标志来告诉它标题的位置，那么它比没有标题的情况下运行编译要好得多。我在下面列出了一些输出（我得到了近300行无法识别的变量）。

我也试过用数学库的-lm标志来运行它，这减少了无法识别的错误，但如果有其他标题库的标志，我就无法找到它们。请帮助!!!!

（使用-I标志运行时出错：）

Answer 1

“未定义的引用”错误不是来自缺少的标题 - 它们是链接器错误，表明您没有链接到对象，也没有指定库的-l（减号）标志，导出这些符号。标题只构成一个承诺，即在链接时提供的对象/库中可以找到与标题声明相匹配的变量和行外函数 - 您正在破坏该承诺。

您需要找到包含这些符号的库，或找到源并编译它们。

I compiled msvar1.3 with command:

gcc -o msvar1.3 myutil.c msvar1.3.c -lm
