# opencv-config(1)

script to get information about the installed version of OpenCV

## NAME

opencv-config - script to get information about the installed version of OpenCV

## SYNOPSIS

**opencv-config** \[ --prefix= *DIR*\] \[ --version \] \[ --libs \[\<extensions\>\]\] \[ --cflags \| --cxxflags \]

## DESCRIPTION

**opencv-config** is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link progams, libraries, and plugins that use OpenCV.

## OPTIONS

- **--cflags**

  Print the C compiler flags that are necessary to compile a program or library that uses OpenCV.

- **--cxxflags**

  Print the C++ compiler flags that are necessary to compile a program or library that uses OpenCV.

- **--libs \[\<extensions\>\]**

  Print the linker flags that are necessary to link a program that uses libcv. Optionally, add linker flags for the libhighgui, libcvcam and/or libcvaux OpenCV extensions by appending highgui, cvcam and/or cvaux.

- **--prefix=***DIR*

  If specified, use PREFIX instead of the installation prefix that libcv was built with when computing the output for the --cflags, --cxxflags and --libs options. This option must be specified before any of the --cflags, --cxxflags and --libs options.

- **--version**

  Prints the currently installed version of libcv on standard output.

## EXAMPLES

- gcc -o main.o $(opencv-config --cflags) -c main.c

  is how you might use **opencv-config** to compile a C source file for an executable program.

- gcc -o my\_app $(opencv-config --libs) main.o util.o

  is how you might use **opencv-config** to link compiled objects into an executable program.
