Hi!  friends,

I tried to build my Android image in my ubuntu 10.04 environment and come across the following error.

I am building the image for i.MX6SL EVK. Could anyone share his/her experience on fixing this problem?

Hi Vincent,

Make sure you are using "android_jb4.3_1.1.0-ga_source" to patch with. If so, I would run the patch again. It will ask to delete the patches; enter yes. It will delete the patches and then, re-patch. Now type:

$ make clobber

Then start your build again.

Hope this helps,

Dave

Hello, Vincent,

    I have tested compiling i.MX6SL android 4.3 BSP on unbunt 12.04 64bit LTS platform, No errors occured. I don't have enough time to set up the same environment with yours, So I recommend you use unbunt 12.04 64bit LTS.

    Attachment is a document written by me , I recorded  all the steps on setting up this environment! But the document is not a formal one, just for you as a reference.

Regards,

Weidong
