2. Build and Install Guide

Prerequisites

Requirement	Details
OS	Ubuntu 20.04+ (or compatible Linux)
CMake	>= 3.6
C++ Compiler	GCC or Clang with C++11 support
URM Core (Libs and Headers)	Needs to be Built and installed first (discussed next)

---

Step 1: Build and Install URM

The extensions depend on the URM core libraries and headers. Follow the instructions at: URM-Build

After this step, the following must be available on your system:

• Libraries: libUrmExtAPIs.so, libRestuneCore.so, libUrmAuxUtils.so
• Headers: Urm/Extensions.h, Urm/UrmPlatformAL.h, Urm/UrmAPIs.h

---

Step 2: Build URM Extensions

git clone https://github.com/qualcomm/userspace-resource-manager-extensions
cd userspace-resource-manager-extensions

# Create a clean build directory
rm -rf build && mkdir build && cd build

# Configure with CMake
cmake .. -DCMAKE_INSTALL_PREFIX=/

# Build
cmake --build .

---

What Gets Built

The CMake build compiles all .cpp files under Extensions/ into a single shared library:

Output	Description
UrmPlugin.so	The extension plugin loaded by URM at startup

CMakeLists.txt Summary

---

Step 3: Install

    sudo cmake --install .

Install Manifest

Source	Installed To	Permissions
UrmPlugin.so	/usr/lib/urm/	Standard library
Configs/*.yaml	/etc/urm/target/	644
Configs/target-specific/qcm6490/	/etc/urm/target/qcm6490/	644
Configs/target-specific/qcs8300/	/etc/urm/target/qcs8300/	644
Configs/target-specific/qcs9100/	/etc/urm/target/qcs9100/	644
initscripts/post_boot/*.sh	/etc/urm/initscripts/post_boot/	755

Note:

• The library installs to CMAKE_INSTALL_LIBDIR/urm/ which resolves to /usr/lib/urm/ on most systems.
• Configs install to CMAKE_INSTALL_SYSCONFDIR/urm/target/ = /etc/urm/target/.

---

Step 4: Start URM Server

From the Build Directory, simply run the executable:

sudo ./urm
