PVS-Studio comes with a plugin that can integrate into the Visual Studio IDE and enables a "one-click" analysis. Since PVS-Studio is first of all designed to work with the Microsoft Visual C++ compiler, we used the corresponding script to generate project files (*.vcxproj) for the Microsoft Visual Studio IDE. There is also a set of scripts to generate project files for a number of different platforms and compilers.
To manage the build process, Unreal Engine employs a build system of its own - Unreal Build Tool. On the Epic Game's, the most active participants were Andy Bayle and Dan O'Connor - it all would have been impossible without their help, so many thanks to them! PVS-Studio integration into Unreal Engine's build process Pavel Eremeev, Svyatoslav Razmyslov, and Anton Tokarev were the participants on the PVS-Studio's part.
And now you are welcome to learn about various interesting things we came across while working on Unreal Engine's source code. Epic Games promised to not only purchase the PVS-Studio license, but would also pay us for our work. Afterwords, Epic would use PVS-Studio on their code base themselves, thus making its integration into their development process as easy and smooth as possible. They suggested we analyze and fix Unreal Engine's source code so that they were completely clear of bugs and the tool wouldn't generate any false positives in the end. But we didn't want to stop there, and thought we should try selling a PVS-Studio license to Epic Games.Įpic Games was very interested in using PVS-Studio to improve the engine continuously over time. The Unreal Engine teamT thanked us for checking their code, and quickly fixed the bugs we reported. We ran an analysis and reported our findings to Epic. Unreal Engine's source code was extraordinarily high quality, but all software projects have defects and PVS-Studio is excellent at surfacing some of the most tricky bugs. As for the project authors, they too benefit by gaining an opportunity to fix some of the bugs.Īmong the articles was " A Long-Awaited Check of Unreal Engine 4". For us, it's a way to have more people learn about our tool. This activity benefits everyone: readers enjoy learning from others' mistakes and discover new means to avoid them through certain coding techniques and style. Take a look at this updatable list of projects we have already checked and written about. As a way of promoting our PVS-Studio static code analyzer, we've thought of an interesting format for our articles: We analyze open-source projects and write about the bugs we manage to find there.
