Step 1: Integrate CodeChecker into your build system

source ~/codechecker/venv/bin/activate

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ make clean
(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker log --build "make depth_magic" --output ./compile_commands.json

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker log --build "make depth_magic" --output ./compile_commands.json

Step 2: Analyze your code

Once the build is logged successfully and the compile_commands.json was created, you can analyze your project.

Step 3: Run the analysis

CodeChecker analyze ./compile_commands.json --enable sensitive --output ./reports

commond line

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker analyze ./compile_commands.json --enable sensitive --output ./reports

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker analyze ./compile_commands.json --enable sensitive --output ./reports

cause reports files

The ./reports directory is the “database” of CodeChecker that allows to manage further working steps.

Step 4: View the analysis results in the command line

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker parse ./reports/

Step 5: Hint: You can do the 1st and the 2nd step in one round by executing check

cd <repo root dir>/docs/examples
make clean
CodeChecker check --build "make" --output ./reports --clean \--enable sensitive

or to run on 22 threads both the compilation and the analysis:

CodeChecker check --jobs 22 --build "make clean ; make --jobs 22" \--output ./reports --clean --enable sensitive

step 6: Export the reports as static HTML files

You can visualize the results as static HTML by executing

(CodeChecker venv) guoqiang@sun:~/depth_magic_ws/deptrum/build$ codechecker parse -e html ./reports/ -o ./reports_html
