[gentoo-dev] xorg's RDEPEND

[gentoo-dev] xorg's RDEPEND

[Rafael Espíndola]

I noticed that xorg-x11-6.8.2-r1.ebuild has a very big RDEPEND. For
example, is there really a need for flex after xorg has been compiled?

Thanks for comments,
Rafael

The RDEPEND:
                >=sys-libs/zlib-1.1.3-r2
                >=sys-devel/flex-2.5.4a-r5
                >=dev-libs/expat-1.95.3
                >=media-libs/freetype-2.1.8
                >=media-libs/fontconfig-2.1-r1
                opengl? ( >=x11-base/opengl-update-2.1.1 )
                >=x11-misc/ttmkfdir-3.0.9-r2
                media-libs/libpng
                >=sys-libs/ncurses-5.1

Let me know once you've tested removing each thing individually, then
run every application in the X distribution in every configuration to
show that there are no dependencies.

I'll be awaiting the bug eagerly.

Thanks,
Donnie

You probably need it, because it has not only the flex binary itself in it, 
but also libfl which is linked to flex-created binaries.

except we dont have a libfl.so which means anything that links against flex 
uses the static library

Fair enough, I just knew of the library and didn't looked to the type of it.

Thats a lot of work, but I can offer a smaller evidence that flex is not needed:

epm -ql xorg-x11 | xargs file  | grep ELF | cut -f 1 -d : | xargs strings | grep -i flex | grep -v circumflex

epm -ql xorg-x11 | xargs file  | grep ELF | cut -f 1 -d : | xargs grep "flex scanner"
Binary file /usr/bin/twm matches
Binary file /usr/bin/xgc matches
Binary file /usr/bin/pswrap matches

those programs work after a emerge -C flex

How is it that you know those two greps will catch everything?

I don't. In fact I am sure they don't catch everything: given a Turing
machine one can replace all halts by a "do something with flex". So it
is undecidable if x11 rdepends on flex (or xbill) and one must prove
it to be sure. I just want to give some indications that flex is not a
dependency.

Another one:
epm -ql flex:
there is some docs, some infos and a man page. I assume that X doesn't
need those.
there is a static lib and a header. As far as I know X doesn't compile
anything after it is installed.
there is the flex binary. As far as I know X doesn't create lexical
analyzer after it is installed.

Please don't missunderstand me. I am not being pedantic. I am creating
a thin-client with gentoo and would like to make it easier for someone
that wants to do that something similar afterwards.

Thanks,
Rafael

emerge pxes

:P

OK, so it isn't exactly the same thing, but I don't see much point in
reinventing the wheel.

Last time I checked this package, it didn't support XOrg X11 (only
XFree86-4.3) and neither did it support linux-2.6 (only linux-2.4) -
both showstoppers for me since the hardware, on which I wanted to deploy
the thin clients, isn't supported by those versions.

I ended up writing a small perl script for automating the build process
of the thin client image instead.

Sincerely,
Brix

I'm working on getting PXES 1.0 (which is based on xorg/2.6) into
portage, but I don't understand the perl-module eclass quite as well as
I wish I did, and something has changed between the versions that makes
simply copying the ebuild not work.
