SNMP交叉编译的技巧

SNMP移植问题

 

哪位高人在ARM平台移植过net-snmp?

请问需要修改的都哪些啊？我改过之后找不到诸如include/linux/route.h这样的头文件，应该怎么处理呢？

 

先在普通PC上configure出来makefile，然后修改相关的makefile文件的CFLAGS这些参数符合arm平台的要求。

 

net-snmp-5.2.1.2,出错如下:

arm-linux-gcc -I../../include -I. -I../../agent -I../../agent/mibgroup -I../../snmplib -g -O2 -Dlinux -c mibII/var_route.c -o mibII/var_route.oIn file included from /usr/local/arm-linux/sys-include/net/route.h:28,

.......

我编译busybox也这样,只要有route的都出错,难道是编译器的问题?我的是GCC-3.2.3的

 

 

不知道这样行不行:先把你的/usr/local/arm-linux/sys-include目录改个名子. 随便给个名字，让编译器认不出来就行了。比如sys-include.old等。

 

编译通过了,高人啊,能给俺讲一下为什么吗?多谢了!

你的编译器在查找头文件时，先找的sys-include目录，但这个目录主要是内核使用的，所以编译会出问题。屏蔽掉这个目录就行了。
