【问题】

在折腾：

【记录】编译配置好的xscale版本的crosstool-ng-1.18.0

期间，解决了：

【已解决】编译crosstool-ng在Installing kernel headers时出错：/home/CLi/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/linux-custom/Makefile:1444: *** mixed implicit and normal rules. Stop.

后，结果又出现另外的错误：

【解决过程】

1.很久很久之前，貌似就见过此问题。

2.参考：

libc/uClibc: fix building on system with recent glibc

去改个别的名字：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\linux-custom\scripts\unifdef.c

改为：

static void             flushline(bool);
//static Linetype         getline(void);
static Linetype         get_line(void);
static Linetype         ifeval(const char **);

......

/*
 * The driver for the state machine.
 */
static void
process(void)
{
	Linetype lineval;

	for (;;) {
		linenum++;
		//lineval = getline();
        lineval = get_line();
		trans_table[ifstate[depth]][lineval]();
		debug("process %s -> %s depth %d",
		    linetype_name[lineval],
		    ifstate_name[ifstate[depth]], depth);
	}
}

/*
 * Parse a line and determine its type. We keep the preprocessor line
 * parser state between calls in the global variable linestate, with
 * help from skipcomment().
 */
static Linetype
//getline(void)
get_line(void)
{

3.修改好之后，用exit 2去继续编译：

[INFO ]  =================================================================

exited with error code: 2

    2  repeat this build command
    3  abort build

ct-ng:~/develop/crosstool-ng/crosstool-ng-1.18.0_build> exit 2

然后就可以继续编译了。

【总结】

如

libc/uClibc: fix building on system with recent glibc

所述，getline的bug，是自从glibc 2.10就有了。

解决办法是：

把getline随便改个别的名字即可。比如get_line，或像：

Patchwork scripts/unifdef.c: rename getline symbol to something else

中去改为parseline等等，都可以。

注意：

文件中不止一处getline，注意要都修改了，不要漏了，才可以。
