This section explains how to compile QIMSDK plugins directly on the target device running Ubuntu.

​
Prerequisites

Before you begin, ensure the following:
  • You have access to a Qualcomm development kit running Ubuntu Linux.
  • You have administrative privileges (sudo access) for installing packages.
  • Internet connectivity for downloading packages and source code.

​
Steps to Compile and Install

To download the source code and compile the sample applications, run the following commands on the Qualcomm development kit.
1

Update user permissions for your session

sudo su
2

Configure Ubuntu package manager to download source code

apt-add-repository -s ppa:ubuntu-qcom-iot/qcom-ppa
3

Build the dependencies

apt build-dep gst-plugins-qti-oss
4

Change directory to home folder

cd /home/ubuntu
5

Download the sources of the QIM Package

apt source gst-plugins-qti-oss
6

Go to QIM root folder

For example:
cd gst-plugins-qti-oss-1.8.1+ubuntu3
7

Run CMake to build and install

cmake -B build -S . \
   -DCMAKE_INSTALL_PREFIX=/usr \
   -DCMAKE_INSTALL_INCLUDEDIR=include \
   -DENABLE_GST_PLUGIN_BASE=1 \
   -DENABLE_GST_IMSDK_PLUGINS=1 \
   -DENABLE_GST_PLUGIN_QMMFSRC=1 \
   -DENABLE_GST_PYTHON_EXAMPLES=1 \
   -DENABLE_GST_SAMPLE_APPS=1 \
   -DENABLE_GST_TEST_FRAMEWORK=1 \
   -DENABLE_GST_PLUGIN_TOOLS=1 \
   -DENABLE_GST_PLUGIN_MLACLASSIFICATION=1 \
   -DENABLE_GST_PLUGIN_MLVCLASSIFICATION=1 \
   -DENABLE_GST_PLUGIN_MLVDETECTION=1 \
   -DENABLE_GST_PLUGIN_MLVPOSE=1 \
   -DENABLE_GST_PLUGIN_MLVSEGMENTATION=1 \
   -DENABLE_GST_PLUGIN_MLVSUPERRESOLUTION=1 \
&& cmake --build build \
&& cmake --install build
After modifying any part of the source code, re-run step 7 to rebuild and reinstall your changes.
