| 6 | Supports: |
| 7 | - aarch32/aarch64 on Linux. |
| 8 | - aarch32/aarch64 on Android. |
| 9 | - x86_32/x86_64 on Linux. |
| 10 | |
| 11 | ## Native Builds |
| 12 | Use the following commands for building on the target machine |
| 13 | |
| 14 | ``` |
| 15 | $ cd external/libhevc |
| 16 | $ mkdir build |
| 17 | $ cd build |
| 18 | $ cmake .. |
| 19 | $ make |
| 20 | ``` |
| 21 | |
| 22 | ## Cross-compiler based builds |
| 23 | |
| 24 | ### Building for x86_32 on a x86_64 Linux machine |
| 25 | ``` |
| 26 | $ cd external/libhevc |
| 27 | $ mkdir build |
| 28 | $ cd build |
| 29 | $ CFLAGS="-m32" CXXFLAGS="-m32" LDFLAGS="-m32" cmake .. |
| 30 | $ make |
| 31 | ``` |
| 32 | |
| 33 | ### Building for aarch32/aarch64 |
| 34 | Update 'CMAKE_C_COMPILER', 'CMAKE_CXX_COMPILER', 'CMAKE_C_COMPILER_AR', and |
| 35 | 'CMAKE_CXX_COMPILER_AR' in CMAKE_TOOLCHAIN_FILE passed below |
| 36 | |
| 37 | ``` |
| 38 | $ cd external/libhevc |
| 39 | $ mkdir build |
| 40 | $ cd build |
| 41 | ``` |
| 42 | |
| 43 | #### For aarch64 |
| 44 | ``` |
| 45 | $ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch64_toolchain.cmake |
| 46 | $ make |
| 47 | ``` |
| 48 | |
| 49 | #### For aarch32 |
| 50 | ``` |
| 51 | $ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch32_toolchain.cmake |
| 52 | $ make |
| 53 | ``` |
