The default (and the recommended) setting, is to use the global toolchain path. In all cases this association is stored in the workspace internal folders, and not in the project configuration, so it is not passed via the repository from one developer to the other. For special projects that require a specific version, it also allows to associate a path to each project. To achieve this, the GNU MCU Eclipse cross build plug-in provides a large selection of existing toolchains, and associate each one with a separate path.

Generating portable projects was one of the design requirements of the GNU MCU Eclipse cross build plug-in, at the same time with the apparently conflicting requirement for handling multiple toolchains and versions. In short, a portable project is a project that can be used without changes on any workspace on any platform.įor more details, please see the separate Project portability page. cproject file, making it non-portable between different machines, and even worse between different platforms (Windows/Unix). Unfortunately it stores this setting in the.
The integrated CDT Cross build plug-in does exactly this, defines a path for each projects. In this case the only recommended solution is to define the toolchain path for each build configuration. However, when multiple toolchains are installed, the use of any global setting is strongly discouraged, since it soon leads to serious problems generally due to messing headers and executables between different toolchains. When only a single toolchain is installed, any global setting is acceptable and the exact method makes no real difference.
This mechanism can be both flexible and a source of nuisance. in the Eclipse workspace, common for all projects.in the environment where Eclipse is started (either a system global setting or a per user setting).Default path management in Eclipse CDTīy default, the Eclipse managed build plug-ins do not handle the toolchain path at all, and rely on the proper setting of the environment PATH to reach the toolchain binaries. Using other toolchains/versions is a different story, more complicated and sometimes even impossible. When using the supplied toolchain, things are extremely easy. Most of the commercial IDEs include the toolchain packed in the distribution, and handle the path to it automatically and transparently for the user. In addition to production environments, in research environments, developers usually experiment with multiple toolchains and toolchain versions, to test their programs. Since toolchains developers are quite active, releasing several versions each year, it soon becomes necessary to manage multiple toolchains, each with multiple versions.
In production environments, when doing maintenance for old products, to obtain repetitive results, it is strongly recommended to build old versions with their original toolchain version. Why use multiple toolchains? Production environments Generally toolchain path management is an advanced feature, required when multiple toolchains are installed on a machine.
