在编译libiconv时出错

./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)

下面报

make[2]: *** [progname.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory `/opt/sources/libiconv-1.14/srclib'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/opt/sources/libiconv-1.14/srclib'
make: *** [all] Error 2

Google搜了好久终于找到一篇文章《libiconv gets undeclared》真是雪中送炭啊。

wget -c http://www.itkb.ro/userfiles/file/libiconv-glibc-2.16.patch.gzcd libiconv-1.14/srclibpatch -p1 stdio.in.h

俺运行patch后好久都没有反应 :( 最后人肉修改

这个补丁的内容如下
