Building cross compilers is always a tricky task. And building canadian-cross compilers can easily drive you crazy. This page provides an overview of working GDC cross compilers and tutorials on how to build your own.

== Building from source ==
=== Existing system root ===
If you have an existing file system for you target or access to the target via SSH, see
[[GDC/Cross_Compiler/Existing_Sysroot]]

=== Crosstool-NG ===
The preferred way to build cross compilers is crosstool-NG. Crosstool-NG supports many different architectures and advanced build configurations (e.g. canadian-cross compilers). The latest crosstool-NG release currently only supports gcc 4.7 though, so we have to use the gdc-4.7 branch there. Newer crosstool-NG hg snapshots do support gcc-4.8.

See [[GDC/Cross Compiler/crosstool-NG|Cross Compiler/crosstool-NG]] for more information.

=== Making tools step by step ===
If it is not possible to use crosstools, the toolchain can be made manually step by step. This can also be used to make a native compiler.

See [[GDC/Cross Compiler/Generic|Cross Compiler/Generic]] for more information.

=== Bare metal ARM Cortex-M ===
See [[Bare Metal ARM Cortex-M GDC Cross Compiler]] for instructions specific to building a bare metal ARM Cortex-M GDC cross compiler.
