# How to integrate PVS-Studio
|
|
|
|
|
|
|
|
|
|
We obtained a free license of PVS-Studio due to the open source nature of Exiv2.
|
|
|
|
|
|
|
|
|
|
## CMake integration
|
|
|
|
|
|
|
|
|
|
To check a project configured with CMake, such as Exiv2, we need to generate the JSON compilation database.
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# Under an already configured "buildXXX" directory
|
|
|
|
|
cd buildXXX
|
|
|
|
|
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON ...
|
|
|
|
|
|
|
|
|
|
# Once the CMake configuration is done, we should obtain a output file 'compile_commands.json'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
The analysis starts with the following commands:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
export PVS_LICENSE=~/.config/PVS-Studio/PVS-Studio.lic
|
|
|
|
|
pvs-studio-analyzer analyze -l $PVS_LICENSE -o pvsStudio.log -j8
|
|
|
|
|
plog-converter -a GA:1,2 -t tasklist pvsStudio.log -o pvsStudio.tasks
|
|
|
|
|
plog-converter -a GA:1,2 -t fullhtml pvsStudio.log -o pvsReportHtml
|
|
|
|
|
plog-converter -a GA:1,2 -d V1042 -t fullhtml pvsStudio.log -o pvsReportHtml
|
|
|
|
|
```
|
