我试图编译和安装在1997年创建的程序。我使用gcc(GCC)4.1.2 20080704(Red Hat 4.1.2-50)和CentOS 5.5版(最终版)。虽然试图做一个“让”命令时,在程序的源目录,我得到以下错误:C程序编译错误

开始考虑这样的C代码的错误后,我试图编译这个在Mac OSX 10.6.7与i686-apple-darwin10-gcc-4.2.1(GCC)4.2.1(Apple Inc. build 5664)。这次我在原始错误之后出现了一个错误,暗示着与游戏中的gcc版本存在不兼容性。这一次的错误是:

C编程和makefiles是完全陌生的,所以我真的不知道从哪里开始。我还可以提供任何其他有助于调试此问题的信息。在select.c定义
select_lines方法如下:
select_lines (int type, void *lines, int n, FILE *infile, FILE *outfile)
{
char line[1024];
int i, current = 0, target;
struct entry *e;
LinesA = make_aarray(SelectAlloc, sizeof(struct entry));
/** Scan in the lines **/
switch (type) {
case LINESFILE:
while (scan_int(target, lines) != EOF) {
new_line(target);
}
break;
case LINESLIST:
for (; n > 0; n--) {
target = *((int *)lines)++;
new_line(target);
}
break;
case LINESRANGE:
for (target = ((int *)lines)[0]; target <= ((int *)lines)[1]; target++) {
new_line(target);
}
break;
default: error("select_lines: Bad type");
}
Lines = (struct entry *) LinesA->contents;
/** Sort by txt sequence **/
qsort(Lines, NLines, sizeof(struct entry), txtcmp);
/** Extract lines **/
current = -1;
for (i = 0; i < NLines; i++) {
target = Lines[i].txt;
if (target < current) error("sort failed");
if (current < target) { /* careful: it's possible to select the same line twice */
while (++current < target) {
skip_line(infile);
}
if (scan_line(line, 1024, infile) == EOF) {
fprintf(stderr, "Premature end of text file");
exit(1);
}
}
Lines[i].line = copy_string(line);
}
/** Resort by smp sequence **/
qsort(Lines, NLines, sizeof(struct entry), smpcmp);
/** Output **/
for (i = 0; i < NLines; i++) {
fprintf(outfile, "%s\n", Lines[i].line);
}
}

@William Pursell。问题已通过select_lines函数更新。谢谢。 – 2011-06-07 21:12:50
