Hi, |
| 2 |
|
| 3 |
I am writing an ebuild for wdiff[1] that depends on GNU diff. So I |
| 4 |
started looking at the diffutils ebuild. More precisely at the |
| 5 |
/usr/portage/sys-apps/diffutils/diffutils-2.8.4-r1.ebuild |
| 6 |
|
| 7 |
The script contains the line |
| 8 |
|
| 9 |
IUSE="nls build" |
| 10 |
|
| 11 |
I understand that "nls" is for activating internationalization options |
| 12 |
but "build", what is it for? |
| 13 |
At http://gentoo.org/dyn/use-index.xml it says that "build" is: |
| 14 |
"!!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating |
| 15 |
build images and the first half of bootstrapping." |
| 16 |
|
| 17 |
<code-snippet> |
| 18 |
IUSE="nls build" |
| 19 |
|
| 20 |
[...] |
| 21 |
|
| 22 |
DEPEND="virtual/glibc |
| 23 |
nls? ( sys-devel/gettext ) |
| 24 |
? !build? ( sys-apps/texinfo )" |
| 25 |
|
| 26 |
RDEPEND="virtual/glibc" |
| 27 |
|
| 28 |
src_unpack() { |
| 29 |
unpack ${A} |
| 30 |
|
| 31 |
cd ${S} |
| 32 |
? if [ -n "`use build`" ] |
| 33 |
? then |
| 34 |
? #disable texinfo building so we can remove the dep |
| 35 |
? cp Makefile.in Makefile.in.orig |
| 36 |
? sed -e 's:SUBDIRS = doc:SUBDIRS =:' \ |
| 37 |
? Makefile.in.orig > Makefile.in |
| 38 |
? fi |
| 39 |
} |
| 40 |
</code-snippet> |
| 41 |
|
| 42 |
The lines I do not understand are marked with "?". |
| 43 |
|
| 44 |
Thanks for your time! |
