Breaking down the 2024 Survey Results | Modern C++ DevOps

- Among the three features surveyed (Concepts, Coroutines, and Modules), Modules have the lowest planned adoption rate, only 29.25% of respondents indicated their projects would allow module usage. As the article C++20 modules and Boost: an analysis highlights, concerns exist around managing the potential increase in complexity for build systems. This is likely in addition to modules introducing interoperability challenges between build systems and package managers - a concern that many of respondents are likely to have as usage of multiple build systems was very high - might delay the adoption process until broader tooling support matures. … ### Build times ​ **Encouraging signs for build times!** So much so, it's included twice. Over the past four years, the survey data reveals a consistent downward trend in the percentage of developers reporting long build times as a major pain point. This decrease of 2.38% from 2021 to 2024 suggests that the C++ build ecosystem is becoming more efficient. There's a still a very slim number of developer who are not burdened by long times times. … ### Setting up a continuous integration pipeline from scratch ​ The survey results indicate a persistent challenge. While there's a slight decrease in the percentage of developers reporting it as a major pain point (down to 1% from 2023 to 2024), it remains a significant hurdle for many (nearly a third of respondents!). There's little to no improvement over the 2021 data. … ### Setting up a development environment from scratch ​ The data on setting up development environments reveals a fascinating trend. While there's a positive shift with more respondents finding it a "not significant" pain point (up to 31.93% in 2024), there's also a concerning slight increase in those reporting it as a major pain (26.27% in 2024). One explanation could be advancements in techniques for build script. There are some very high quality sources for CMake. That category saw a in the number of respondents experiencing pain that. However, the challenge of setting up the entire environment, especially for complex systems, seems to be persisting.
