在AIX6.1和GCC4.2下面使用libperfstat.h出现问题

fengzhw 2011-05-21 01:03:18

gcc aixcpu.c -o acpu -lperfstat
In file included from /usr/include/sys/corral.h:25,
from /usr/include/libperfstat.h:28,
from aixcpu.c:10:
/usr/include/netinet/in6_var.h:65: error: array type has incomplete element type

不过AIX自己的xlc是没问题的，上面的编译命令只要把gcc换成cc就可以通过。
上网搜了一些，都没明确说怎么解决。这里有ibm的人么，能帮着出个主意么？

不行就得周一联系ibm support了。

那个改法我也搜到了，但是存在两个严重问题：
一、系统头文件可以随便改么？抛开权限问题，这个一致性问题就很严重；

二、为什么xlc好使，gcc就不好使？同样的程序在AIX 5.2上用GCC 4.0是没问题的。

[Quote=引用 2 楼 fengzhw 的回复:]

看过了，没找到线索

那到底是什么内容呢

Google了一下，说是把
in6_var.h中的

extern CONST struct protosw inet6sw[];

改为

extern CONST struct protosw *inet6sw[];
