Header File Not Found During Source File Scan with the Tiancheng Code Optimizer

Symptom

When running the tool, a message is displayed indicating that the header file cannot be found.

Possible Causes

The project, system, or other header files for the source file cannot be found.

Troubleshooting Procedure

• The project header file cannot be found.

  When scanning the source file, use the -r parameter to specify the root directory of the project containing the source file. The Tiancheng Code Optimizer will then automatically analyze and locate the required header files.

• The system header file cannot be found.
  1. Download the BiSheng Compiler (BiSheng Compiler 4.2.0 in earlier versions) and upload it to a custom directory (for example, /home/demo) on the server.
  2. Extract the BiSheng Compiler installation package.

     cd /home/demo
     tar -zxvf BiShengCompiler-4.2.0-aarch64-linux.tar.gz 

  3. Add the following environment variables to ~/.bashrc:

     export INCLUDE=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib/clang/17/include/:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/include:$INCLUDE  
     export C_INCLUDE_PATH=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib/clang/17/include/:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/include:C_INCLUDE_PATH  
     export CPLUS_INCLUDE_PATH=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib/clang/17/include/:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/include:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/include/c++/v1/:$CPLUS_INCLUDE_PATH  
     export LD_LIBRARY_PATH=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib64:$LD_LIBRARY_PATH  
     export LIBRARY_PATH=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib:/home/demo/BiShengCompiler-4.2.0-aarch64-linux/lib64:$LIBRARY_PATH  
     export PATH=/home/demo/BiShengCompiler-4.2.0-aarch64-linux/bin:$PATH

  4. Make the configuration take effect.

     source ~/.bashrc

• Other header files cannot be found.

  When scanning the source file, use the -I parameter to specify the path to a missing header file. Multiple -I parameters can be used together.
