Hi all,

I have a solution, as captured here:
    Bug 12363 - unset BBPATH before starting bbserver for Rocko compatibility

(a) When Toaster is running, it has the build environment of the checkout that started it.

(b) When Toaster launches a managed build, it sources the build environment in the respective build directory using the "oe-init-build-env" from the bitbake that is the Release that the project was created for.

(c) Normally, the build environment's values completely eclipses the Toaster environment's values, and there is no problem.

HOWEVER, the new "oe-init-build-env" in master has now added BBPATH, where previously that was left undefined. What this means is that the BBPATH from master Toaster is polluting any builds for Rocko, and the direct consequence is that the "bitbake.lock" file is redirected to the Toaster directory where it is not found.

The simple fix is to always clean this (and any other such values) from the environment before lauching builds.

I will submit the fix to bitbake-dev tomorrow.

Subject: [Toaster] Toaster installations on master cannot build Rocko projects

Hi All,

I am observing something strange.

If I have a "Rocko" installation of Toaster, I can build both "Master" and "Rocko" based projects.

However, I have found that if I have a recent "Master" installation of Toaster I can build "Master" projects, but I get fatal timeouts for projects based on "Rocko" and I have to manually cancel the build.

I am investigating how Master has diverged from Rocko. In the meantime I advise using one of the above working combinations.
