OPENSSL編譯步驟
源碼下載和解壓
wget https://www.openssl.org/source/old/1.1.1/openssl-1.1.1f.tar.gz
tar -zxvf openssl-1.1.1f.tar.gz
導(dǎo)入ndk環(huán)境變量
export ANDROID_NDK_HOME=/home/username/ndk/android-ndk-r20b
export PATH=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin:$ANDROID_NDK_HOME/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin:$PATH
編譯arm32位openssl
./Configure android-arm -D__ANDROID_API__=23 --prefix=/home/username/openssl/out/arm/
make clean
make & make install
編譯arm64位
./Configure android-arm64 -D__ANDROID_API__=23 --prefix=/home/username/openssl/out/arm64/
make clean
make & make install
--prefix路徑：必須先創(chuàng)建

CURL編譯
源碼下載和解壓
wget https://curl.se/download/curl-7.84.0.tar.gz
tar -xvzf curl-7.84.0.tar.gz
導(dǎo)入NDK編譯環(huán)境
export NDK=/home/username/ndk/android-ndk-r20b
export HOST_TAG=linux-x86_64 # 按照當(dāng)前設(shè)備環(huán)境來
export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/$HOST_TAG
export AR=$TOOLCHAIN/bin/aarch64-linux-android-ar
export AS=$TOOLCHAIN/bin/aarch64-linux-android-as
export CC=$TOOLCHAIN/bin/aarch64-linux-android29-clang
export CXX=$TOOLCHAIN/bin/aarch64-linux-android29-clang++
export LD=$TOOLCHAIN/bin/aarch64-linux-android-ld
export RANLIB=$TOOLCHAIN/bin/aarch64-linux-android-ranlib
export STRIP=$TOOLCHAIN/bin/aarch64-linux-android-strip
編譯curl
./configure --host aarch64-linux-android --with-pic --disable-shared
make
編譯支持https協(xié)議curl
# 將openssl編譯相關(guān)結(jié)果內(nèi)容拷貝至ndk路徑
cp -a /home/username/openssl/out/arm64/lib /home/username/ndk/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/
# 如果缺少相關(guān)openssl頭文件，將頭文件openssl/openssl-1.1.1f/include/openssl拷貝至ndk路徑下，r20b版本已經(jīng)包含，忽視本步驟
cp -a /home/username/openssl/openssl-1.1.1f/include/openssl /home/username/ndk/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include
編譯curl (支持https)
./configure --host aarch64-linux-android --with-pic --disable-shared --with-openssl="${TOOLCHAIN}/sysroot/usr"
make
輸出curl在當(dāng)前curl源碼路徑下src/curl
注意事項
在android 8.1系統(tǒng)上，如果要使用支持https的curl，必須先支持openssl
