折腾：
【记录】Ubuntu下用crosstool-ng为xscale建立交叉编译器arm-xscale-linux-gnueabi-gcc
编译出错：

| [ERROR] gtype-desc.c:8829:18: error: subscripted value is neither array nor pointer nor vector |
【解决过程】
1.参考：
Bug 52986 – x86_64 GCC 4.7.0 can’t compile x86 GCC 4.6.2; gtype-desc.c
->
Bug 51969 – [4.6 regression] trunk gcc unable to build gcc 4.6
去修改gtype-desc.c，结果找不到这个文件。
2.然后去修改：
gcc/gengtype.c
crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/gcc-4.6.0/gcc$ gedit gengtype.c
找到write_field_root，改为：
static void
write_field_root (outf_p f, pair_p v, type_p type, const char *name,
int has_length, struct fileloc *line, const char *if_marked,
bool emit_pch, type_p field_type, const char *field_name)
{
struct pair newv;
/* If the field reference is relative to V, rather than to some
subcomponent of V, we can mark any subarrays with a single stride.
We're effectively treating the field as a global variable in its
own right. */
if (v && type == v->type)
{
//struct pair newv;
newv = *v;
newv.type = field_type;然后再去重新编译：
然后就可以继续编译了：
【总结】
编译gcc 4.6时出现：
| [ERROR] gtype-desc.c:8829:18: error: subscripted value is neither array nor pointer nor vector |
时，解决办法是：
把
（在
| crosstool-ng-1.18.0_build/.build/src |
下面的）
gcc-4.6.0/gcc/gengtype.c |
中的函数write_field_root中的
struct pair newv;
移到最开始声明处，即改为这样：
static void
write_field_root (outf_p f, pair_p v, type_p type, const char *name,
int has_length, struct fileloc *line, const char *if_marked,
bool emit_pch, type_p field_type, const char *field_name)
{
struct pair newv;
/* If the field reference is relative to V, rather than to some
subcomponent of V, we can mark any subarrays with a single stride.
We're effectively treating the field as a global variable in its
own right. */
if (v && type == v->type)
{
//struct pair newv;
newv = *v;
newv.type = field_type;即可。
