QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
解决方案：
重新下载一个libiconv-1.14
./configure --prefix=$PWD/out --host=arm-none-linux-gnueabi
make
make install然后把out/lib/preloadable_libiconv.so拷贝到板子的/lib，并在板子的文件系统增加一个环境变量
export LD_PRELOAD=/lib/preloadable_libiconv.so
编译过程可能还有个错误：
修改libiconv-1.14的文件： srclib/stdio.in.h
./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)
用下面的这个补丁：
