 Posted: Thu Jan 23, 2014 4:36 am Post subject: how to solve the libpng dependency problem? |
 |
|
when I was trying to update the system by
the following part always pop out that prevents updates:
| Code: | media-libs/libpng:0
(media-libs/libpng-1.5.17-r1::gentoo, ebuild scheduled for merge) pulled in by
>=media-libs/libpng-1.4:0/0= required by (app-editors/emacs-24.3-r2::gentoo, installed)
(and 1 more with the same problem)
(media-libs/libpng-1.6.7::gentoo, installed) pulled in by
media-libs/libpng:0/16= required by (app-text/poppler-0.24.5::gentoo, installed)
media-libs/libpng:0/16= required by (dev-qt/qtgui-4.8.5-r1::gentoo, installed)
media-libs/libpng:0/16= required by (x11-libs/cairo-1.12.14-r4::gentoo, installed)
>=media-libs/libpng-1.4:0/16= required by (x11-libs/gdk-pixbuf-2.28.2::gentoo, installed)
media-libs/libpng:0/16= required by (www-client/links-2.8-r1::gentoo, installed)
media-libs/libpng:0/16= required by (media-libs/jbig2dec-0.11-r1::gentoo, installed)
|
I tried to mask media-libs/libpng-1.5.17-r1::gentoo in package.mask, but it still doesn't work by saying I need to unmask it.
if I uninstall emacs 24, maybe the problem could be solved. But I do wish to keep emacs24 in the system.
here is the results by emerge -av libpng
| Code: |
Calculating dependencies... done!
[ebuild R ~] media-libs/libpng-1.6.7:0/16 USE="apng static-libs (-neon)" ABI_X86="(64) -32 (-x32)" 0 kB |
any great ideals? thanks in advance! |

suggest first run As media-libs/libpng-1.6.8 is the latest stable version. Then then retry | Code: | emerge -uND world | tee wg
wgetpaste wg
rm wg |
post the url returned

Hi Donahue, follow your method, I have got (haven't got the reason):
| Code: |
(gentoo) C665D package.mask # emerge -uND world | tee wg
Calculating dependencies
* IMPORTANT: 3 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.
... . .... done!
!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:
sys-libs/zlib:0
(sys-libs/zlib-1.2.8-r1::gentoo, installed) pulled in by
sys-libs/zlib:=[minizip] required by (www-client/chromium-32.0.1700.77::gentoo, ebuild scheduled for merge)
(sys-libs/zlib-1.2.8-r1::gentoo, ebuild scheduled for merge) pulled in by
(no parents that aren't satisfied by other packages in this slot)
It might be possible to solve this slot collision
by applying all of the following changes:
- sys-libs/zlib-1.2.8-r1 (Change USE: +minizip)
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
# required by dev-python/pycurl-7.19.0-r3[ssl]
# required by app-admin/system-config-printer-common-1.4.3
# required by app-admin/system-config-printer-gnome-1.4.3
# required by gnome-base/gnome-control-center-3.8.6[cups]
# required by gnome-base/gnome-shell-3.8.4-r2
# required by gnome-base/gdm-3.8.4-r3[gnome-shell]
# required by @selected
# required by @world (argument)
>=net-misc/curl-7.34.0-r1 curl_ssl_nss -curl_ssl_openssl
Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.
!!! The ebuild selected to satisfy "sci-libs/hdf5[mpi=]" has unmet requirements.
- sci-libs/hdf5-1.8.10::gentoo USE="cxx fortran fortran2003 mpi (multilib) static-libs szip zlib -debug -examples -threads" ABI_X86="64"
The following REQUIRED_USE flag constraints are unsatisfied:
cxx? ( !mpi ) mpi? ( !cxx )
The above constraints are a subset of the following complete expression:
cxx? ( !mpi ) mpi? ( !cxx ) threads? ( !cxx !mpi !fortran ) fortran2003? ( fortran )
(dependency required by "sci-visualization/paraview-4.0.1-r1" [ebuild])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
(gentoo) C665D package.mask # rm wg

wgetpaste wg should have returned a pastebin url which should have contained a complete copy of the output of emerge -uND world.
it appears the libpng problem has cleared.
| Code: | echo ">=sys-libs/zlib-1.2.8-r1 minizip" >> /etc/portage/package.use
echo ">=net-misc/curl-7.34.0-r1 curl_ssl_nss -curl_ssl_openssl" >> /etc/portage/package.use
echo ">=sci-libs/hdf5-1.8.10::gentoo cxx -mpi" >> /etc/portage/package.use
emerge -auND world |
mpi and cxx use flags are mutually exclusive; I flipped a coin and picked cxx and banned mpi; have no idea of what either is for

thanks @Donahue
yes it is working when i use
but the problem on libpng shows up again when i use the following command to update
I have read about the meaning of -N from the emerge manpage, but still didn't get the idea of it. especially how -N can handle the problem of libpng I had before |

| -N is --newuse - it forces portage to check if some useflags have changed and rebuild the packages affected by a useflag change... |
