## +24 ## Beyond Compilation Databases to Support C++ Modules: Build Databases ## BEN BOECKEL ## Who am I? • 15 years working on build systems and software process • CMake developer ○ Designing and build systems xmake □ bazel ## Outline 1. What are compilation databases? 2. How do modules change the status quo? 3. Build databases ## Compilation Databases: Overview • JSON document • Array of JSON (optional) ☐ Arguments (list of strings) or command (single string, shell escaped) ## Today: Compilation Databases • Specified by the Clang project https://clang.llvm.org/docs/JSONCompilationDatabase

The typical use case for this is to mark the interpreter of an embedded language as STATIC: {-#

conan.cmake) have been upgraded to accommodate this new default. ### 1.4 New features • Cross-compilation support with new default settings in settings.yml: os_build, arch_build, os_target, arch_target packages. The packages are created by the client, and if binaries are built from sources, that compilation is also done by the client application. ![Image](/uploads/documents/8/a/2/d/8a2d62d3212ed3e30 source: Where the source code for building from sources is stored. • build: Where the actual compilation of sources is done. There will typically be one subfolder for each different binary configuration

Guidance on how the Agda editing and compilation system can be Static values The STATIC pragma can be used to mark definitions which should be normalised before compilation. The typical use case for this is to mark the interpreter of an embedded language as STATIC: {-# with the current top-level module. This information is interpreted by the specific backend during compilation (see below). These pragmas were added in Agda 2.5.3. #### 3.7.2 Haskell FFI Note: This section

Dependent running cabal v2-install, you'll get the following error when compiling with the GHC backend: Compilation error: MAlonzo/RTE.hs:13:1: error: Failed to load interface for 'Numeric.IEEE' Use -v

multiple dispatch, and good performance, achieved using type inference and just-in-time (JIT) compilation, implemented using LLVM. It is multi-paradigm, combining features of imperative, functional, and for the actual argument types passed by the caller. For example, calling fib(1) will trigger the compilation of specialized version of fib optimized specifically for Int arguments, which is then re-used if called a "run-time type" in object-oriented languages where the combination of static compilation with polymorphism makes this distinction significant. • Only values, not variables, have types

it can compile code from various programming languages, including Kotlin. Kotlin/Wasm is a new compilation target for Kotlin. You can use it in your Kotlin Multiplatform projects. With Kotlin/Wasm, you Xallow-unstable-dependencies These checks are exclusively disabled for kapt tasks. All other compilation tasks will continue to utilize the new K2 compiler. If you encounter any issues when using kapt versions below 8.3 in the following cases: - Compilation of source code from buildSrc . - Compilation of Gradle plugins in included builds. - Compilation of other Gradle plugins if they are used in projects
