Hi Alex,

A simple test case to demonstrate the issue consists in adding libpci-dev 
as a build dependency to example-hello
I have forked and modified hello for this purpose and modifed the recipe as 
follows:

diff --git a/meta-isar/recipes-app/example-hello/example-hello.bb 
b/meta-isar/recipes-app/example-hello/example-hello.bb
index 602a11e..af87428 100644
--- a/meta-isar/recipes-app/example-hello/example-hello.bb
+++ b/meta-isar/recipes-app/example-hello/example-hello.bb

 SRC_DIR = "git"
 
If I bitbake example-hello, do_build will fail. The log will show:

The following NEW packages will be installed:
  libpci-dev libpci3 zlib1g-dev
0 upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
1 not fully installed or removed.
Need to get 317 kB of archives.
After this operation, 703 kB of additional disk space will be used.
Do you want to continue? [Y/n] Abort.

We get an "Abort" because we do not have a stdin when building from bitbake.

Hope this helps

Cedric
