I have an ebuild in /usr/local/portage and I've ran emerge --sync yet whenever I try to emerge it it says it cannot be found.

Also, did I do my USE flags right with $GUI $SOUND ect.?

USE="$GUI $SOUND $GRAPHICS $MISC"

Your 'USE' variable as it is will be EMPTY (well only the useflags in your profile will be on) if you only define your 'GUI','SOUND', 'GRAPHICS', 'MISC' variables after the fact! Define your 'USE' variable AFTER you defined the variables you want to be included.

You don't need to do 'emerge --sync' to pick up changes in your overlays, please explain how you added your ebuild to your local portage tree

No. You are passing those temporaries as environment variables to the packages you build. In some cases, this can confuse the package into doing something strange. You should use only the standard names in /etc/make.conf. Please post the output of find /usr/local/portage -ls.

Which I got from: http://gpo.zugaina.org/x11-wm/cairo-compmgr/euscan

I've never used an ebuild before, but whenever I do ebuild <.ebuild> digest I get

Code: Select all

# ebuild cairo-compmgr-0.3.0.ebuild digest
Appending /usr/local to PORTDIR_OVERLAY...
!!! /usr/local/portage/x11-misc/cairo-compmgr-0.3.0.ebuild does not seem to have a valid PORTDIR structure.

Thanks for y'alls help.

Look at the official portage tree, it goes like this
[PORTAGE_OVERLAY]/[PACKAGE_CATEGORY]/[PACKAGE_NAME]/[PACKAGE_NAME]-[VERSION].ebuild
in your case this would be
/usr/local/portage/x11-misc/cairo-compmgr/cairo-compmgr-0.3.0.ebuild
the place where you need to put your ebuild.

You still need to create a manifest though before being able to emerge it, like this:

Code: Select all

ebuild /usr/local/portage/x11-misc/cairo-compmgr/cairo-compmgr-0.3.0.ebuild digest

Also note that your ebuild is ~arch keyworded, so unless you have

Code: Select all

ACCEPT_KEYWORDS="~[YOUR_ARCH]"

in your /etc/make.conf, you will need to add 'x11-misc/cairo-compmgr' to your '/etc/portage/package.keywords'

EDIT: One thing I noticed. Why do you want it in the 'x11-misc' category instead of the 'x11-wm' as seen in the source overlay? Not that it would make a difference when trying to install it, but is it just changing it for the sake of changing it?

[PostChache]

Thanks that solved that!

Now I'm getting this error

Code: Select all

 # ACCEPT_KEYWORDS="~amd64" emerge -av cairo-compmgr

 * IMPORTANT: 4 news items need reading for repository 'gentoo'.
 * Use eselect news to read news items.


These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "dev-lang/vala:0".
(dependency required by "x11-misc/cairo-compmgr-0.3.0" [ebuild])
(dependency required by "cairo-compmgr" [argument])

 * IMPORTANT: 4 news items need reading for repository 'gentoo'.
 * Use eselect news to read news items.

Do you know how I should go about this? I have vala already so I went and changed the ebuild from vala:0 to just vala, but I still ended up getting an error so I don't know if that was the right thing to do.


Edit:

I saw that the ebuild has a label for bgo-overlay so I found this one on the forum
