Now gcl is keyworded ~arm (#509842), and maxima can be built on arm. One pecularity of the maxima ebuild: it can build maxima with any (non-empty) subset of 6 lisps, depending on USE flags; if no lisp USE flags are given, it defaults to sbcl. On arm, only gcl is available. Therefore, it is necessary to specify the USE flag gcl for emerging maxima. It would be good to use FEATURES=test to run self-tests, though this may take a lot of time on a slow processor.
Created attachment 379276 [details] dev-lisp:ecls-13.5.1-r1:20140530-102126.log I didn't forget about this one, but there are a few issues... The following packages are needed to (properly) keyword sci-mathematics/maxima on arm: =app-misc/rlwrap-0.37 =dev-lisp/sbcl-1.1.18 =dev-lisp/uiop-3.0.3 =dev-lisp/asdf-3.0.3 =app-emacs/auctex-11.87-r1 =app-emacs/imaxima-1.0-r3 =dev-lisp/ecls-13.5.1-r1 =sci-mathematics/maxima-5.33.0 dev-lisp/ecls fail to build here. For me it looks like there's a bundled ffi that seems to be failing... log attached.

Things are not *that* bad. It is sufficient to have at least 1 lisp (out of 6 supported ones) to compile maxima. And now we have gcl, this is sufficient. No need to have ecls or sbcl. The USE flags gcl, cmucl, clozurecl are masked in base/use.mask, and unmasked only in selected arches. I'll do the same with sbcl, ecls, clisp. Also, I'll edit the maxima ebuild slightly. If a user specifies none of these 6 USE flags, the default lisp is used; currently, it's sbcl. I'll make the default lisp on arm to be gcl. After I'll do this change, there will be no need to keyword ecls, sbcl, and hence also asdf and uiop on arm. Also rlwrap is not needed. It is needed if maxima is built with some lisp which does not support readline itself. But gcl supports readline. After the mentioned change in the maxima ebuild it will not depend on rlwrap on arm (it will depend on it only under some USE flags which are masked on arm). You are absolutely right that imaxima is needed, and it also needs auctex. I think it wouldn;t be too difficult to keyword them. By the way, the lisp system sbcl has been ported to arm very recently: arm support has appeared in its latest version 1.2.0. I plan to commit an sbcl-1.2.0 ebuild within a few days. After that, it will be possible to try it on sbcl. But this may be non-trivial, sbcl is a rather strange beast (it's not a C program compiled by gcc, unlike, say, gcl; sbcl bootstraps itself). But let's not try do do everything at once and immediately. sbcl can wait. To summarize: I'll do some changes in masking/unmasking USE flags and in the maxima ebuild; after that, you'll need to keyword only maxima, imaxima, and auctex.
Sorry for the long delay, was busy with other things :-( I've just committed a modified maxima-5.33.0.ebuild. If the user gives none of the lisp USE flags, the default lisp is used. Now, on arm the default lisp is gcl. All lisp USE flags except gcl are masked on arm. So, on arm maxima can never depend on any other lisp. Also, rlwrap now showld not be needed on arm. If there are any problems with keywording imaxima and auctex, we can trivially mask the USE flag emacs for maxima in package.use.mask, and they will not be needed. Then you can keyword just 1 package, maxima. But if auctex and imaxima work on arm (and there are no reasons why they shouldn't), you can keyword all 3 of them, and avoid masking the emacs USE flag.
Andrey, thanks for your work on this one. The new ebuilds (still) build fine on my arm box! There still seems to be a problem with sbcl and rlwrap dependencies: $ ekeyword ~arm maxima-5.34.1.ebuild WARNING: 'portageq portdir' is deprecated.

RepoMan sez: "Make your QA payment on time and you'll never see the likes of me." Do I need to mask some flags or is there anything else I am missing?
In recent versions DEPEND and RDEPEND were in fact wrong. I've fixed this in maxima-5.37.3-r1. If I add ~arm to maxima-5.37.3-r1 and app-emacs/imaxima-1.0-r3, repoman full says everything's all right. Please check that maxima actually compiles on arm and keyword it (together with imaxima) ~arm. A personal question, sorry: I plan to buy a good tablet, maybe samsung galaxy tab s2. I heard that it's possible to install Gentoo on top of Android, because top-level directories in / don't intersect. Where can I read more about it? Is it neccessary to root the tablet? Will I have a Gentoo ~arm device on which I'll be able to compile and test packages?
Starting from 5.37.3-r3, there is no separate package app-emacs/imaxima. So, you only need to keyword sci-mathematics/maxima-5.37.3-r3, nothing else. (Of course, if there are problems with maxima with USE=emacs, this USE flag can be masked on arm.)
