Caching Compiler (RECC) CppCon 2024 September 19, 2024 Shivam Bairoliya Software Engineer© 2024 Bloomberg Finance L.P. All rights reserved. What is RECC? ● Remote Execution Caching Compiler (RECC) ○ Open source build tool that wraps compiler commands and optionally forwards them to a remote build execution service ○ Encompasses the capabilities of both ccache and distcc ○ Supports remote linking linking and caching ● Designed to share caches across diverse toolchains ○ Works with many compiler toolchains (GCC, Clang, Solaris CC) ○ Supports multiple operating systems (Linux, macOS, Solaris)

Additionally, here are some of the main highlights: 新版 Kotlin K2 编译器更新 The Kotlin team at JetBrains continues to stabilize the K2 compiler, and the 1.9.0 release introduces further advancements. The K2 compiler for the JVM is now in Beta. There's now also basic support with the K2 compiler, but with some restrictions. Despite setting languageVersion to 2.0 , the kapt compiler plugin still utilizes the old compiler. If you execute the kapt compiler plugin within
