我正在尝试按照此处的说明为 MIPS 系统交叉编译 GLib 2.37.0 。我有一个 mips.cache 文件，其中包含以下内容：
glib_cv_stack_grows=no
glib_cv_uscore=no
ac_cv_func_posix_getpwuid_r=no
ac_cv_func_posix_getgrgid_r=no
我正在使用以下命令行调用配置脚本：
./configure --cache-file=mips.cache --host=mips-linux CCFLAGS=-I/opt/toolchain/build_mips/staging_dir/usr/include LDFLAGS=-L/opt/toolchain/build_mips/staging_dir/usr/lib
不幸的是，我收到了这个错误：
configure: error: *** No iconv() implementation found in C library or libiconv

我试过用该--with-libiconv=no选项调用配置脚本，但结果是一样的。我从其他来源知道 mips.cache 文件很好，但我不知道让配置脚本工作的魔力。我还使用这个工具链来交叉编译其他应用程序。我在这里想念什么？
谢谢！
