libjpeg-turbo-master_build

基于 https://github.com/libjpeg-turbo/libjpeg-turbo 编译的静态和动态链接库

这个老哥编译的，目前的ndk-build，我不知道为啥不能编译通过 https://github.com/bither/bither-android-lib

所以我自己无聊编译了一次，有armv7，armv8，x86，为什么没有arm？因为我按最新的脚本，脚本没教我怎么编译arm，如下是我最新拉libjpeg-turbo-master看到的脚本命令

参考编译的博客https://segmentfault.com/a/1190000017900195

大佬编译好，写的库有https://github.com/JavaNoober/Light

Building libjpeg-turbo for Android

Building libjpeg-turbo for Android platforms requires v13b or later of the Android NDK.

ARMv7 (32-bit)

The following is a general recipe script that can be modified for your specific needs.

# Set these variables to suit your needs
NDK_PATH={full path to the NDK directory-- for example,
  /opt/android/android-ndk-r16b}
TOOLCHAIN={"gcc" or "clang"-- "gcc" must be used with NDK r16b and earlier,
  and "clang" must be used with NDK r17c and later}
ANDROID_VERSION={the minimum version of Android to support-- for example,
  "16", "19", etc.}

cd {build_directory}
cmake -G"Unix Makefiles" \
  -DANDROID_ABI=armeabi-v7a \
  -DANDROID_ARM_MODE=arm \
  -DANDROID_PLATFORM=android-${ANDROID_VERSION} \
  -DANDROID_TOOLCHAIN=${TOOLCHAIN} \
  -DCMAKE_ASM_FLAGS="--target=arm-linux-androideabi${ANDROID_VERSION}" \
  -DCMAKE_TOOLCHAIN_FILE=${NDK_PATH}/build/cmake/android.toolchain.cmake \
  [additional CMake flags] {source_directory}
make

ARMv8 (64-bit)

The following is a general recipe script that can be modified for your specific needs.

# Set these variables to suit your needs
NDK_PATH={full path to the NDK directory-- for example,
  /opt/android/android-ndk-r16b}
TOOLCHAIN={"gcc" or "clang"-- "gcc" must be used with NDK r14b and earlier,
  and "clang" must be used with NDK r17c and later}
ANDROID_VERSION={the minimum version of Android to support.  "21" or later
  is required for a 64-bit build.}

cd {build_directory}
cmake -G"Unix Makefiles" \
  -DANDROID_ABI=arm64-v8a \
  -DANDROID_ARM_MODE=arm \
  -DANDROID_PLATFORM=android-${ANDROID_VERSION} \
  -DANDROID_TOOLCHAIN=${TOOLCHAIN} \
  -DCMAKE_ASM_FLAGS="--target=aarch64-linux-android${ANDROID_VERSION}" \
  -DCMAKE_TOOLCHAIN_FILE=${NDK_PATH}/build/cmake/android.toolchain.cmake \
  [additional CMake flags] {source_directory}
make

x86 (32-bit)

The following is a general recipe script that can be modified for your specific needs.

# Set these variables to suit your needs
NDK_PATH={full path to the NDK directory-- for example,
