Build error

[AndrewD79]

Hi,
We have attempted to build an OpenWRT image for Linkit Smart7688 recently.
Previously the build worked with no issue, but it now seems to fail based on doxygen2jsdoc issues.

See log error below.
I have seen some other cases where this has been mentioned elsewhere.
Note that there are 55 objects checked out, but at this link, they are able to download 57 items( https://www.bountysource.com/issues/38947746-packages-libmraa-compile-error)
Is that relevant?
All other searches/suggestions for this type of error suggest that there is a failed/uncommitted change to your repo.
We are unable to build our production environment until this is resolved.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

@AndrewD79
How did you continue the building process?
I had the same problem :(

hi. have you solved this issue now? I also met the same issue.
thanks.

[hitfzyangdianshi]

I solve this issue:
The problem is about git submodule setup. The main branch of https://github.com/eclipse/mraa uses submodule of https://github.com/intel-iot-devkit/doxygen2jsdoc . However, the old version of mraa (for example tag v0.8.0 https://github.com/eclipse/mraa/tree/v0.8.0) uses submodule of https://github.com/arfoll/doxygen2jsdoc . So use the following steps:

establish a folk of https://github.com/eclipse/mraa in your own github repository
create a branch from the old version tag (for example, v0.8.0)
remove all the other branches
then in the feeds/packages/libs/libmraa/Makefile , change PKG_SOURCE_URL to your own github repository.
