12.1.5. Building from Source on Windows using scons - 5.2 English - 57404

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

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

2. Navigate to the folder:

   $ cd aocl-libm-ose
   

3. Install virtualenv:

   $ pip install virtualenv
   

4. Initialize the environment for correct architecture using Visual Studio vcvarsall.bat file using following command:

   $ "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
   

5. Activate virtual environment and install SCons inside:

   $ virtualenv -p python .venv3
   $ .venv3\Scripts\activate
   $ pip install scons
   

6. Build the project using the clang compiler:

   Basic build command: scons ALM_CC=<clang-cl executable path> ALM_CXX=<clang-cl executable path> --aocl_utils_install_path="<libaoclutils library path>"
   
   Additional Flags:
   
   Build in parallel: -j<number of parallel builds>
   Verbosity: --verbose=1
   Debug mode build: --debug_mode=libs
   

   For example:

   $ scons -j32 ALM_CC="C:\PROGRA~1\LLVM\bin\clang-cl.exe" ALM_CXX="C:\PROGRA~1\LLVM\bin\clang- cl.exe" --verbose=1
   

By default, the static (libalm-static.lib) and dynamic (libalm.dll and libalm.lib) libraries are compiled and generated in the following location:

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

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

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