交叉编译用于MIPS的GLib导致“无iconv（）实现”配置错误

Question

我试图按照指示here为MIPS系统交叉编译GLib 2.37.0。我有以下内容的mips.cache文件：

glib_cv_stack_grows=no 
glib_cv_uscore=no 
ac_cv_func_posix_getpwuid_r=no 
ac_cv_func_posix_getgrgid_r=no 

我打电话用下面的命令行配置脚本：

./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 

不幸的是我得到这个错误：

configure: error: *** No iconv() implementation found in C library or libiconv 

如果有帮助，整个输出是：

我试过用--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文件是好的，但我不知道让配置脚本起作用的魔力。我也使用这个工具链来交叉编译其他应用程序。我在这里错过了什么？

谢谢！

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