Building OpenCV with ARM Performance Libraries (ARMPL) on Windows {#tutorial_windows_armpl}
==================================================================
@prev_tutorial{tutorial_windows_install}
@next_tutorial{tutorial_linux_install}
| | |
| -: | :- |
@tableofcontents
Introduction {#tutorial_windows_armpl_intro}
============
This tutorial explains how to build OpenCV on Windows (AArch64) with
[ARM Performance Libraries (ARMPL)](https://developer.arm.com/Tools%20and%20Software/Arm%20Performance%20Libraries)
as a math backend. ARMPL provides optimized BLAS and LAPACK routines for Arm-based hardware
and can significantly accelerate OpenCV operations such as DFT and DCT.
Step 1: Download and Install ARM Performance Libraries {#tutorial_windows_armpl_download}
=====================================================
1. Open a browser and go to the
[ARM Performance Libraries Downloads page](https://developer.arm.com/Tools%20and%20Software/Arm%20Performance%20Libraries#Downloads).
2. Under **Windows / AArch64**, download the installer for your preferred toolchain:
| File | Architecture | Size |
|------|--------------|------|
| `arm-performance-libraries_26.01_Windows.msi` | AArch64 | ~240 MiB |
3. Run the downloaded `.msi` installer and follow the on-screen instructions.
The default installation directory is:
```
C:\Program Files\Arm Performance Libraries\armpl_26.01
```
Step 2: Configure System Environment Variables {#tutorial_windows_armpl_env}
=============================================
OpenCV's CMake scripts (and the ARMPL runtime itself) need to find the library files at both
build time and run time. Add the following entries to the **System** `PATH` variable:
1. Open **System Properties**, click **Advanced**, then **Environment Variables**.
2. Under **System variables**, select `Path` and click **Edit**.
3. Add the two paths below (adjust the version number if yours differs):
```
C:\Program Files\Arm Performance Libraries\armpl_26.01\lib
C:\Program Files\Arm Performance Libraries\armpl_26.01\bin
```
4. Click **OK** on every dialog to save.
Step 3: Clone OpenCV {#tutorial_windows_armpl_clone}
====================
```bat
git clone https://github.com/opencv/opencv.git
cd opencv
```
If you also need the extra modules:
```bat
git clone https://github.com/opencv/opencv_contrib.git
```
Step 4: Configure with CMake {#tutorial_windows_armpl_cmake}
============================
Create a build directory and run CMake with ARMPL support enabled.
**Without OpenMP (single-threaded ARMPL):**
```bat
mkdir build && cd build
cmake -G "Visual Studio 17 2022" -A ARM64 ^
-DWITH_ARMPL=ON ^
-DARMPL_ROOT_DIR="C:\Program Files\Arm Performance Libraries\armpl_26.01" ^
-DWITH_OPENMP=OFF ^
..
```
**With OpenMP (multi-threaded ARMPL):**
ARMPL ships both serial and OpenMP-enabled library variants. To use the multi-threaded variant,
enable OpenMP in CMake:
```bat
mkdir build && cd build
cmake -G "Visual Studio 17 2022" -A ARM64 ^
-DWITH_ARMPL=ON ^
-DARMPL_ROOT_DIR="C:\Program Files\Arm Performance Libraries\armpl_26.01" ^
-DWITH_OPENMP=ON ^
..
```
@note Enabling `WITH_OPENMP=ON` causes CMake to link against the `armpl_lp64_mp` (multi-threaded)
variant of ARMPL. Disabling it links against the serial `armpl_lp64` variant. Only one variant
should be enabled at a time to avoid symbol conflicts.
Step 5: Build and Install {#tutorial_windows_armpl_build}
=========================
Open the generated `.sln` file in Visual Studio and build the **Release** configuration, or
build from the command line:
```bat
cmake --build . --config Release --parallel
cmake --install . --config Release
```
Step 6: Verify the Build {#tutorial_windows_armpl_verify}
=========================
After a successful build, confirm that OpenCV detects ARMPL by running:
```bat
opencv_version --verbose 2>&1 | findstr /i armpl
```
You should see a line similar to:
```
ARMPL: YES (armpl_26.01)
```
Alternatively, check the CMake configuration log for the line:
```
-- ARMPL support: YES
```
Troubleshooting {#tutorial_windows_armpl_troubleshoot}
===============
**CMake cannot find ARMPL:**
Make sure `ARMPL_ROOT_DIR` points to the folder that contains both `include\` and `lib\`
sub-directories:
```
C:\Program Files\Arm Performance Libraries\armpl_26.01
bin\
include\
lib\
```
**Runtime error: DLL not found:**
Ensure that both the `lib\` and `bin\` directories are on the system `PATH` and that
you opened a new Command Prompt after adding them (changes are not picked up by already-open
sessions).
**Linker errors with OpenMP:**
If you see duplicate symbol errors when `WITH_OPENMP=ON`, make sure you are not also linking
against the serial ARMPL library. Pass `-DWITH_OPENMP=ON` consistently and clean the build
directory before re-running CMake.

@param filename Name of the file to open or the text string to read the data from.
Extension of the file (.xml, .yml/.yaml or .json) determines its format (XML, YAML or JSON
respectively). Also you can append .gz to work with compressed files, for example myHugeMatrix.xml.gz. If both
FileStorage::WRITE and FileStorage::MEMORY flags are specified, source is used just to specify
respectively). Also you can append .gz to work with compressed files, for example myHugeMatrix.xml.gz.
You can also specify a compression level from 0 to 9 by appending it to the extension
(e.g. ".gz0" for no compression, ".gz9" for high compression).
The last digit will be truncated internally to write/read.
(e.g. If "a.xml.gz9" is specified, "a.xml.gz" is used for the actual file name.)
If both FileStorage::WRITE and FileStorage::MEMORY flags are specified, source is used just to specify
the output file format (e.g. mydata.xml, .yml etc.). A file name can also contain parameters.
You can use this format, "*?base64" (e.g. "file.json?base64" (case sensitive)), as an alternative to
FileStorage::BASE64 flag.
