Obtain the specific toolchain for your chip (e.g., gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf.tar.xz ). Extract it to a directory such as /tools/toolchain/ .
The SigmaStar SDK includes an ARM cross-compilation toolchain.
To compile the SDK, you must tell the system where the toolchain is located. You can add this to your ~/.bashrc file for convenience.

The process is not insurmountable, but it demands respect for legacy toolchains, fixed paths, and vendor-specific build steps. By following this guide—preparing a clean Ubuntu 20.04 host, extracting carefully, configuring per your board, and methodically building each component—you will move from a raw SDK tarball to a booting SigmaStar device.
Installing a is generally a complex, manual process that requires a highly specific environment. While the software is powerful for IP camera and multimedia development, the installation "review" is often one of high friction due to strict dependency and legacy system requirements. Installation Experience Overview
Create this structure:
sudo apt install python2.7 sudo ln -s /usr/bin/python2.7 /usr/local/bin/python
Extract the toolchain to a global system directory like /opt :
Ensure you have read/write permissions for the opt directory if installing the toolchain there. Setting up the USB/SD burning tools to flash your board?
