构建iconv

Android

ndk版本在25左右构建通过

ICONV_PREFIX=/usr/local/iconv-android
ANDROID_NDK=/path/to/ndk/xx.xxx.xxxxxx
ANDROID_ARCH=aarch64
ANDROID_API=21
ANDROID_HOST=$ANDROID_ARCH-linux-android$ANDROID_API
ANDROID_SYSROOT=$ANDROID_NDK/toolchains/llvm/prebuilt/windows-x86_64/sysroot

PATH=$ANDROID_NDK/toolchains/llvm/prebuilt/windows-x86_64/bin:$PATH

./configure --host=$ANDROID_HOST \
--with-sysroot=$ANDROID_SYSROOT \
--prefix=$ICONV_PREFIX \
--enable-static \
--disable-shared \
CC=$ANDROID_HOST-clang \
CXX=$ANDROID_HOST-clang++

Windows
