最近在编译openwrt中出现了这种情况，错误如下:

首先的感觉是没有安装libiconv链接库，我使用的ubuntu系统，但是检查后libiconv-hook-dev软件包已经安装上了，/usr/lib下面也有正确的链接，ldconfig检查也没发现什么问题（如果是指定在/usr/local/lib下，可以先安装后使用ln -sf /usr/lib/libiconv.so.2.5.1 /usr/local/lib/libiconv.so.2
ln -sf /usr/lib/libiconv_hook.so.1.0.0 /usr/local/lib/libiconv_hook.so.1来将libiconv.so.2.5.1和libiconv_hook.so.1.0.0链接到/usr/local/lib中。）

网上搜索一番无果后，通过openwrt官方搜索，在此链接下提到（链接：https://dev.openwrt.org/ticket/10956）Adding -liconv to TARGET_LDFLAGS seems to fix the problem. 。之前是用过–with-liconv来指定libiconv路径的，无效。于是编辑/feeds/packages/libs/libsoup下的Makefile文件，在-Wl-rpath-link=$(STAGING_DIR)/usr/lib 部分插入-liconv。修改后如下： TARGET_LDFLAGS+=\ -Wl,-liconv,-rpath-link=$(STAGING_DIR)/usr/lib

问题解决。

另 编译libsoup需要libsqlite3支持。
