[gentoo-user] strange ebuild problem

[gentoo-user] strange ebuild problem

[Helmut Jarausch]

Hi,
I have an ebuild containing

inherit git-r3

and

src_compile() {

	./build_all.sh
}

The script build_all.sh contains

[ -d csources ] || git clone --depth 1  
https://github.com/nim-lang/csources.git


When I try to build I get the strange error
fatal: unable to access 'https://github.com/nim-lang/csources.git/':  
Could not resolve host: github.com

But when I exec
git clone --depth 1 https://github.com/nim-lang/csources.git
in an xterm (i.e. without using 'ebuild') it succeeds.

What's going on here?

Many thanks for a hint,
Helmut

Hi Helmut

I believe this is a consequence of the sandboxing of ebuilds.

When I had the same problem with an ebuild trying to download many things
from the Maven repository, I added the following lines inside the ebuild:
# To enable Maven access to https://repo.maven.apache.org/maven2
RESTRICT="network-sandbox"

It is described (shortly) in "man 5 ebuild"
This is forbidden in the Portage tree, but is allowed in your own overlay.

Best regards

Many, many thanks Micka. I'd never thought of that.

Stay healthy,
Helmut
