 Posted: Wed Sep 23, 2009 1:49 pm Post subject: A little ebuild help: uhub-0.2.8 |
 |
|
I'm trying to write an ebuild for my local overlay, but am having a bit of trouble. This is my first ebuild, so I'm not very familiar with them.
This is what I have so far:
| Code: | # Copyright 1999-2009 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $
DESCRIPTION="A high performance direct connect hub supporting the ADC protocol"
HOMEPAGE="http://www.extatic.org/uhub/intex.html"
SRC_URI="http://www.extatic.org/downloads/uhub/${P}-src.tar.bz2"
LICENSE="GPL-3"
SLOT="0"
KEYWORDS="x86"
DEPEND="sys-devel/make
>sys-devel/gcc-3.0
>=dev-libs/libevent-1.3
dev-lang/perl"
scr_unpack() {
unpack ${A}
cd "${S}"
}
scr_compile() {
make || die "make failed"
}
src_install() {
make DESTDIR="${D}" install || die "make install failed"
} |
When I emerge the package, I get the following error:
| Code: | >>> Install uhub-0.2.8 into /var/tmp/portage/net-p2p/uhub-0.2.8/image/ category net-p2p
Copying uhub to /var/tmp/portage/net-p2p/uhub-0.2.8/image//usr/local/bin/
cp: cannot create regular file `/var/tmp/portage/net-p2p/uhub-0.2.8/image//usr/local/bin/': No such file or directory
make: *** [install] Error 1 |
I can compile and install the program fine when done manually with a make install, so I am not sure what is causing issues for the ebuild. Maybe something with the makefile? Any help would be appreciated.
edit:
for what its worth, this is the GNUmakefile:

In playing with this, I figured that the error could just be the lack of a space, in the DESTDIR variable, since it shows it with the source and destination directories together. | Code: | >>> Install uhub-0.2.8 into /var/tmp/portage/net-p2p/uhub-0.2.8/image/ category net-p2p
Copying uhub to /var/tmp/portage/net-p2p/uhub-0.2.8/image//usr/local/bin/
cp: cannot create regular file `/var/tmp/portage/net-p2p/uhub-0.2.8/image//usr/local/bin/': No such file or directory
make: *** [install] Error 1 |
So I added a space to DESTDIR in the scr_install section, and now get a sandbox error when trying to copy the file.
This is the modified ebuild:

unpack ${A}
cd "${S}"
}
scr_compile() {
make || die "make failed"
}
src_install() {
make DESTDIR="${D} " install || die "make install failed"
} |
And this is the error:

Any ideas? Should I post this in Portage & Programming?

Thanks for posting the ebuild, it works great. I do have a few questions, since I'd like to better understand how to write ebuilds. Since installing from the install script works perfectly, I assume that the need to change the ebuild is for sandboxing reasons. Why exactly are the changes you made necessary? I know from the Gentoo Dev Guide what tc-getAR and the other functions do, but I'm not sure why that is needed. Why do I need to know what the archiver indexer is? To be honest, I don't know what the archiver indexer is.
My background is in embedded hardware, but I have done a bit of C programming for micorcontrollers, so this stiff is quite a bit different than what I've done in the past.
Thanks

$(tc-getAR) function will return the full name of ar, such as, x86_64-pc-linux-gnu-ar in amd64 system. the fullname is required for cross compiling (embedded) targets properly. same applies
to others like tc-getCC, tc-getLD, and so forth. |

Someone should post this at bugs.gentoo.org and create baselayout script. I'm surprised it isn't there yet.
