12.1.4. Building from Source on Linux using scons - 5.2 English - 57404

Refer to Installing AOCL to install the AOCL-Utils library. Then, complete the following steps to compile AOCL-LibM:

1. Download source from GitHub (amd/aocl-libm-ose).

2. Navigate to the LibM folder and checkout the branch aocl-5.2:

   $ cd aocl-libm-ose
   $ git checkout aocl-5.2
   

3. Create a virtual environment:

   $ virtualenv -p python3 .venv3
   

4. Activate the virtual environment:

   $ source .venv3/bin/activate
   

5. Install SCons:

   $ pip install scons
   

6. Compile AOCL-LibM:

   Basic build command: scons --aocl_utils_install_path=<libaoclutils library path>
   
   Additional Flags
   
   Build in parallel: -j<number of parallel builds>
   Installation: install --prefix=<path to install>
   Compiler selection: ALM_CC=<gcc/clang executable path>
   ALM_CXX=<g++/clang++ executable path>
   Verbosity: --verbose=1
   Debug mode build: --debug_mode=libs
   

7. By default, the libraries (static and dynamic) will be compiled and generated in the following location:

   aocl-libm-ose/build/aocl-release/src/

   If a debug mode build has been selected, the libraries (static and dynamic) will instead be compiled and generated in the following location:

   aocl-libm-ose/build/aocl-debug/src

   If the installation option is used, the libraries will also be copied to the directory <path to install>/lib.
