### T113 Issue on Ubuntu For addressing issues related to the T113 development board specifically within an Ubuntu environment, several key points must be considered when setting up and configuring the SDK as per official documentation[^1]. An additional package installation is required beyond what's outlined in the standard setup instructions: To ensure compatibility with certain graphical components of the Longan Linux SDK for T113, executing `sudo apt-get install libgl1-mesa-dev:i386` becomes necessary. This command installs a 32-bit version of OpenGL libraries that might not automatically get installed during typical SDK configuration processes. When encountering errors such as "mkimage command not found", which prevents building U-Boot images—a critical part of preparing bootable firmware—installing specific tools can resolve this issue. Running `sudo apt install u-boot-tools` ensures all utilities needed for creating U-Boot images are available, thus enabling successful compilation without similar obstacles. A symbolic link creation step mentioned at the end was omitted from execution according to user notes. While skipping this may work under some circumstances depending upon how paths and dependencies have been set up elsewhere in one’s system or project structure, it could lead to potential problems later unless explicitly unnecessary due to alternative configurations already present. ```bash # Install essential packages including those noted above sudo apt-get update && sudo apt-y sudo apt-essential git-core gcc g++ make \ bzip2 flex wget libncurses5-dev zlib1g-dev libssl-dev \ python unzip bash-completion bc libelf-dev cmake \ libgl1-mesa-dev:i386 u-boot-tools ``` --related questions-- 1. What other common pitfalls should developers watch out for while working with T113 boards? 2. How does omitting the final ln -s command affect subsequent operations involving compiled binaries? 3. Are there any known conflicts between different versions of Ubuntu and the T113 SDK? 4. Can you provide guidance on troubleshooting missing commands like mkimage outside of installing u-boot-tools?
