LIBAVC

Getting Started Document

LibAVC build steps

Supports:

  • aarch32/aarch64 on Linux.
  • aarch32/aarch64 on Android.
  • x86_32/x86_64 on Linux.

Native Builds

Use the following commands for building on the target machine

$ cd external/libavc
$ mkdir build
$ cd build
$ cmake ..
$ make

Cross-compiler based builds

Building for x86_32 on a x86_64 Linux machine

$ cd external/libavc
$ mkdir build
$ cd build
$ CFLAGS="-m32" CXXFLAGS="-m32" LDFLAGS="-m32" cmake ..
$ make

Building for aarch32/aarch64

Update 'CMAKE_C_COMPILER', 'CMAKE_CXX_COMPILER', 'CMAKE_C_COMPILER_AR', and 'CMAKE_CXX_COMPILER_AR' in CMAKE_TOOLCHAIN_FILE passed below

$ cd external/libavc
$ mkdir build
$ cd build

For aarch64

$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch64_toolchain.cmake
$ make

For aarch32

$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch32_toolchain.cmake
$ make

Building for android

NOTE: This assumes that you are building on a machine that has Android NDK.

$ cd external/libavc
$ mkdir build
$ cd build

Armv7 (32-bit)

cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android_toolchain.cmake\
    -DAVC_ANDROID_NDK_PATH=/opt/android-ndk-r26d/\
    -DANDROID_ABI=armeabi-v7a\
    -DANDROID_PLATFORM=android-23 ../
make

Armv8 (64-bit)

cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android_toolchain.cmake\
    -DAVC_ANDROID_NDK_PATH=/opt/android-ndk-r26d/\
    -DANDROID_ABI=arm64-v8a\
    -DANDROID_PLATFORM=android-23 ../
make
