如何使用android ndk 用介子编译glib 2.66？

Question

环境：

编译器：android-ndk-r21b，api 24

Ubuntu 20.04

Glib 2.66

我已经构建了 iconv，并且已经成功构建了 glib 2.56，现在我尝试使用介子构建 glib 2.66，我构建并运行这个脚本：

OUTDIR=$HOME/work/ndk/builddir/out
CC=arm-linux-androideabi-gcc CFLAGS="-L$OUTDIR/lib -I$OUTDIR/include" LDFLAGS="-L$OUTDIR/lib" LIBS="-liconv" CXXFLAGS="-L$OUTDIR/lib" meson release/ \
    --cross-file cross_file.txt \
    --prefix=$OUTDIR \

但编译错误：

Header <iconv.h> has symbol "iconv_open" : YES 

meson.build:1930:4: ERROR: C shared or static library 'iconv' not found

A full log can be found at /home/git/work/ndk/builddir/glib-2.66.4/reconfigure/meson-logs/meson-log.txt

cross_file.txt：

我明白了。我不应该设置 c_ld 变量。并且 gio 的介子脚本中有一个错误，所以我必须在 ubuntu 上删除 libelf-dev（或修改 gio/meson.build）。

访问我的github获取配置文件：
