用天嵌的编译环境便宜PPP2。4。5和2。4。4出错！！

arm-linux-gcc -o radius.so -shared radius.o libradiusclient.a
libradiusclient.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status
make[2]: *** [radius.so] Error 1
make[2]: Leaving directory `/opt/EmbedSky/ppp-2.4.4/pppd/plugins/radius'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/opt/EmbedSky/ppp-2.4.4/pppd/plugins'
make: *** [all] Error 2

上面是错误信息！2。4。5也是也样。。。
