我正按照here的指示，尝试为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configure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

我尝试使用--with-libiconv=no选项调用configure脚本，但结果是一样的。我从其他来源得知mips.cache文件很好，但我不知道让configure脚本工作的神奇之处。我还使用此工具链来交叉编译其他应用程序。我在这里缺少什么？
谢谢！

这是因为libiconv不会使用正确的编译器（在这种情况下为mips编译器）构建，或者库（.so）在配置glib时指定的路径中不存在。
