Build issue..."Not a git repository"

[Bob Stewart]

Hi,
I started getting build warning message about repository not found, as
you can see below. This occurred shortly after I did a make prepare for
libc and libm from libports on my 16.05 build. I'm building from the
BUILD_DIR directory. An suggestion why this is occurring?

Hello,

It looks to me like this is caused by core and libc trying to get some version
information from git, but it is failing because the current working directory
(BUILD_DIR) is not inside a git repository. In the case of core it is only a
cosmetic issue, and version information was removed from libc not long after
it was introduced, so as you move further down the master branch that warning
will disapear regardless.

Thanks for the reply Emery.

I've been building Genode the same way for several years and never seen these messages, and BUILD_DIR has never been inside a git repository. I suspect it is related to building libc in 16.05.

You're right and as Emery wrote: The second warning will disappear
with the next release (or with the current master branch).
Nevertheless, I'm curious why you see the first warning as git is used
like follows in repos/base/src/core/version.inc.

git -C $(GENODE_ROOT_DIR) describe --dirty=" <local changes>" 2> /dev/null

On my machine, this line effectivle prevents warnings from git for any
GENODE_ROOT_DIR, for example

GENODE_ROOT_DIR=/tmp

Hi Christian,

The file repos/base/src/core/version.inc in my release directory has the same content as the current master. In that file, line 4 sets:

GENODE_ROOT_DIR = $(BASE_DIR)/../..

If I change that to set it to /tmp I still get the two git repository warnings.
