![]() Some likely places for the avr-gcc toolchainĪ likely place for configuration files like nf find command: if the test file is not on the system $PATH, then the plugin will start searching the following directories (and their subdirectories) in order:.which command: Test if the test file is on the system $PATH.To find this test file the following external commands are executed in order until a successful match is found: The plugin currently assumes that all non-Windows platforms are Posix based.Įach path has a test file associated with it, which will be searched for. The paths are taken from the Windows registry for the winAVR and AVR Tools applications. The method of determining the system path is different on Windows and non-Windows machines: Windows This is the path as determined by the Plugin itself. Path sourcesįor each path the plugin requires, three different sources are possible: The user then has a fully working toolchain without needing to compile it himself. This will allow ISV to compile an up-to-date toolchain and distribute it to users, using the Eclipse update mechanism. A bundled toolchain will be a normal avr-gcc toolchain wrapped in a Eclipse plugin. In both cases, the system path might not point to the toolchain the plugin user actually wants to use.Īlso, as the AVR Eclipse Plugin grew in features, it required access to some specific files that are not on the system path, like the include file.Īnother reason for implementing a path management was the inclusion of toolchain bundles in future versions of the plugin. Besides this, the winAVR installer asks if the user wants to include winAVR in the system paths, which he might decline for some reason. But even here the user might want to install multiple versions of winAVR, for example to try out newer versions while keeping the previous version. On Windows the winAVR toolchain is the de-facto standard and it is usually up-to-date.Therefore many AVR developers will probable compile the avr-gcc toolchain themselves, but keep it in a separate location from the distribution supplied toolchain. On non-Windows platforms the avr-gcc toolchain supplied by the distributions is often out-of-date and does not contain the latest patches.AVR Plugin path management AVR Plugin path management BackgroundĮarly versions of the AVR Eclipse Plugin (prior 2.1) relied on the system path of the development system to execute the required tools ( avr-gcc, avr-size, make etc.) ![]()
