Languages and compilers

The current versions of the CodeQL CLI (changelog, releases), CodeQL library packs (source), and CodeQL bundle (releases) support the following languages and compilers.

Language	Variants	Compilers	Extensions
C/C++	C89, C99, C11, C17, C23, C++98, C++03, C++11, C++14, C++17, C++20, C++23 [1] [2] [3]	Clang (including clang-cl [4] and armclang) extensions (up to Clang 19.1.0), GNU extensions (up to GCC 15.0), Microsoft extensions (up to VS 2022), Arm Compiler 5 [5]	.cpp, .c++, .cxx, .hpp, .hh, .h++, .hxx, .c, .cc, .h
C#	C# up to 13	Microsoft Visual Studio up to 2019 with .NET up to 4.8, .NET Core up to 3.1 .NET 5, .NET 6, .NET 7, .NET 8, .NET 9	.sln, .csproj, .cs, .cshtml, .xaml
GitHub Actions	Not applicable	Not applicable	.github/workflows/*.yml, .github/workflows/*.yaml, **/action.yml, **/action.yaml
Go (aka Golang)	Go up to 1.24	Go 1.11 or more recent	.go
Java	Java 7 to 24 [6]	javac (OpenJDK and Oracle JDK), Eclipse compiler for Java (ECJ) [7]	.java
Kotlin	Kotlin 1.6.0 to 2.2.0x	kotlinc	.kt
JavaScript	ECMAScript 2022 or lower	Not applicable	.js, .jsx, .mjs, .es, .es6, .htm, .html, .xhtm, .xhtml, .vue, .hbs, .ejs, .njk, .json, .yaml, .yml, .raml, .xml [8]

[1]

C++20 modules are not supported.

[2]

C23 and C++23 support is currently in beta.

[3]

Objective-C, Objective-C++, C++/CLI, and C++/CX are not supported.

[4]

Support for the clang-cl compiler is preliminary.

[5]

Support for the Arm Compiler (armcc) is preliminary.

[6]

Builds that execute on Java 7 to 24 can be analyzed. The analysis understands standard language features in Java 8 to 24; “preview” and “incubator” features are not supported. Source code using Java language versions older than Java 8 are analyzed as Java 8 code.

[7]

ECJ is supported when the build invokes it via the Maven Compiler plugin or the Takari Lifecycle plugin.

[8]

JSX and Flow code, YAML, JSON, HTML, and XML files may also be analyzed with JavaScript files.

[9]

The extractor requires Python 3 to run. To analyze Python 2.7 you should install both versions of Python.

[10]

Requires glibc 2.17.

[11]

Requires rustup and cargo to be installed. Features from nightly toolchains are not supported.

[12]

Support for the analysis of Swift requires macOS.

[13]

TypeScript analysis is performed by running the JavaScript extractor with TypeScript enabled. This is the default.

Frameworks and libraries

The current versions of the CodeQL library and query packs (source) have been explicitly checked against the libraries and frameworks listed below.

Tip

If you’re interested in other libraries or frameworks, you can extend the analysis to cover them. For example, by extending the data flow libraries to include data sources and sinks for additional libraries or frameworks.
