Description subwooferbone 2016-04-13 12:21:38 UTC

Using latest Buildroot Eclipse plugin.

Importing CDT project from another user, all build targets are gone. Eclipse complains "An error has occurred. See error log for more details.
java.lang.NullPointerException".

C/C++ Build and C/C++ General pages of project properties are borked, null pointers galore. 

Same behaviour with both Mars and Luna. Uninstalling the plugin makes the C/C++ options pages work again, but it is impossible to select another toolchain for the projects defined with buildroot toolchains. Then complains about orphaned toolchain.

Message sent to stderr: "Managed Build system manifest file error: Option org.buildroot.home.bob.software_PI1509.platform.buildroot.output..toolchain.base.option.path.1204713667 uses a null category that is invalid in its context. The option was ignored."

Thanks for your bug report. However, this bug is not directly related to Buildroot, but rather to its Eclipse plugin. Could you report it to the Buildroot Ecplise plugin issue tracker available at https://github.com/mbats/eclipse-buildroot-bundle/issues ?

In addition, I am not sure this can work by design. Indeed, a CDT project definition will include a reference to the selected toolchain, which uses an absolute path. This absolute path is relevant on the machine where the project was created, but will not make sense on any other machine. Since I'm not an Eclipse user, I have no idea how this is typically handled in other situations.
