Build and install

Dependencies

These are the minimum requirements to build the driver:

• gcc
• make
• linux-headers >= 3.16.0

Additional tools that may be useful for development:

• libelf
• kmod
• sparse
• Qt Creator

Build and install

You can build and install akvcam with the following commands:

cd akvcam/src
make
sudo make install USE_DKMS=1

after that, the driver may work without problems. You can check the driver is installed with:

ls /lib/modules/$(uname -r)/extra/akvcam.ko*

And you can uninstall the driver with:

sudo make uninstall USE_DKMS=1

If you are just packaging akvcam, remove the USE_DKMS=1 flag, and run DKMS manually:

sudo dkms install akvcam/${VERSION}

Replace ${VERSION} with the actual driver version.

Build flags

• KERNEL_DIR: The path where kernel source are located. Default to /lib/modules/$(shell uname -r)/build.
• DESTDIR: The install prefix of the driver, used with make install. Default to /.
• USE_SPARSE=1: Use sparse to check for errors in source files when building.
• SPARSE_MODE: Mode 1 only check errors when the source file is modified, mode 2 check errors every time the driver is built. Default to 2.

Install flags

• USE_DKMS: Run DKMS after install/before uninstall.

Build and develop with Qt Creator

You can open the driver source code as a normal Qt project, to do so just open the akvcam.pro file with Qt Creator and that's it. Qt Creator offers a lot of nice and modern features to improve driver development like static code parsing, error, warning and source tracking, and a lot more.
