When starting by double-clicking SuperMap iDesktopX.exe, there is no permission to read/write data in system directories. Solutions include:

• Option 1: Move data to a non-system directory and change output paths to non-system directories (recommended);
• Option 2: Right-click SuperMap iDesktopX.exe and select "Run as administrator";
• Option 3: Right-click SuperMap iDesktopX.exe, select "Properties," change permissions to administrator, then rerun the executable.

This occurs due to missing Microsoft Visual C++ runtime. In the product installation path\SuperMap\SuperMap iDesktopX\support folder, double-click vcredist110_x64.exe. After successfully installing Microsoft Visual C++ 2012, SuperMap iDesktopX will start normally.

This is caused by failed DLL loading. Solutions:

1. Restart SuperMap iDesktopX;
2. If the error persists, open the SuperMap.Desktop.Parameter.xml file in the product package\configuration folder, change "<loadDll loadDll="true"/>" to False;
3. After modification, restart SuperMap iDesktopX.

To accommodate different Linux system CPU architectures, the Linux desktop version provides x86, Arm, and Loongson product packages, each in tar, deb, and rpm formats. Selection criteria:

1. Package type selection:

• For X86 CPU architectures, use x86 Linux packages;
• For ARM CPU architectures, use arm Linux packages;
• For Loongson CPU architectures, use Loongson Linux packages.

2. Package format selection:

• tar.gz green package: Extract and use directly, compatible with all Linux OS;
• deb installation package: Install and use, suitable for Ubuntu, Kylin, UOS, etc.;
• rpm installation package: Install and use, suitable for NeoKylin, CentOS, etc.

1. Commands for rpm package installation and removal:

• Installation command: rpm -i filename_of_package_to_install
• Removal command: rpm -e supermap-idesktopx

Commands for deb package installation and removal:

• Installation command: dpkg -i filename_of_package_to_install
• Removal command: dpkg -r supermap-idesktopx

1. Set LD_LIBRARY_PATH environment variable to point to bin: export LD_LIBRARY_PATH=./bin:$LD_LIBRARY_PATH
2. Confirm missing library (e.g., libpng12.so.0): ldd -d libWrapjGeo.so |grep libpng12.so.0
   If output: libpng12.so.0 => not found, the file is missing.
3. Search for libpng12.so files in the OS: find / -name libpng12.so.*
   If output shows files (e.g., /snap/core/4917/lib/x86_64-linux-gnu/libpng12.so.0), copy to bin. If not found, obtain elsewhere.
4. Copy libpng12.so.0 to bin: cp /snap/core/4917/lib/x86_64-linux-gnu/libpng12.so.0 ./bin
5. Check for other missing libraries: ldd libWrapj.so |grep no
6. If no missing libraries, start iDesktopX.

1. Install java-1.8.0-openjdk: Execute in command line: yum install java-1.8.0-openjdk;

2. Switch to the system's JRE environment: Comment out "export JRE_PATH=./jre/bin" in startup.sh (add #), as shown:

3. Install font dependencies: yum -y install xorg-x11-xauth xorg-x11-utils xorg-x11-fonts-*

4. Restart iDesktopX.

On SUSE, third-party database clients must be installed to load SDX data engines correctly. Failure of one SDX engine affects others, preventing data source access or startup. SDX engines requiring third-party clients include: libSuEngineSRDB.sdx, libSuEngineOracle.sdx, libSuEngineDMCI.sdx, libSuEngineOsp.sdx, libSuEngineAltibase.sdx, libSuEngineDB2.sdx, libSuEngineKDB.sdx. For example, to use Oracle data sources, first install the Oracle client, then delete all *.sdx files except libSuEngineOracle.sdx before starting SuperMap iDesktopX. Apply similar steps for other databases.

Solution: Keep libSuEngineImagePlugin.sdx and required database engine files in the bin directory of the product package, and delete unneeded *.sdx files from the list above.

Download the systemlibs compressed package corresponding to the OS fromhttps://pan.baidu.com/s/1-ohLlVdnoYfxF_uzkCD8DA?pwd=9rrb, extract it, copy missing libraries to the root directory/support/browser folder, and restart the software.

Example: If starting on Linux64 reports "version 'NSS_3.65' not found (required by /lib64/libsmime3.so", download linux64_systemlibs.tar.gz from the link, extract it, copy libsmime3.so to root directory/support/browser, and restart.

SuperMap iDesktopX requires JRE 1.8 or newer. Since the JRE version is insufficient, Java fails to start. Solutions:

• Option 1: Uninstall the old JRE and install JRE 1.8 or newer, then restart;
• Option 2: Modify the startup.sh script by moving "$JRE_PATH:" to the front in "export PATH=$SUPERMAP_ROOT:$LD_LIBRARY_PATH:$JRE_PATH:$PATH" to become "export PATH=$JRE_PATH:$SUPERMAP_ROOT:$LD_LIBRARY_PATH:$PATH". Rerun startup.sh.

Note: This issue is resolved in version 9D, eliminating JRE compatibility problems.

1. Troubleshooting & Isolating the Installation Package Issue: The product package can be extracted normally, and the package integrity is confirmed. The focus shifts to the runtime environment.

2. Verifying the Runtime Environment:

   • Test 1: Check the Java Runtime Environment (JRE) Attempt to execute the command: ./[Product_Package_Path]/jre/bin/java -version. If the command fails, it indicates a missing or permission-related issue in the base runtime environment. Proceed to Test 2.

   • Test 2: Check Dynamic Library Dependencies Set the library path: export LD_LIBRARY_PATH=./bin:$LD_LIBRARY_PATH. Then, navigate to the bin directory and execute ldd lib* | grep no found to check for missing libraries. If this command also cannot be executed, the system might be preventing the application from calling critical library files.

3. Solution：Access the "Security Center" or a similar settings interface in the UOS. Change the corresponding policy from "Only allow certified applications to run" to "Allow any application to run."
