h2. IP Clearance: Impact

The following list describes the impact on GUI level of removal and replacement of libraries
as described on the [IP_Clearance|IP_Clearance] page.  Its intended purpose is to keep track
of lost or modified functionality.

|| Library || What is changing\\ || User Impact ||
| lp_solve | lp_solve is being replaced by CoinMP\\
| CoinMP comes from the [Coin-OR|] open source project, an open source
project that involves operations research professionals and includes cutting edge algorithms.\\
|\\ | This functionality is invoked by the user in Calc via Tools->Solver.   It
is used for solving linear programming problems, including integer  programming.\\
According to one [research paper|]
CoinMP offers superior performance compared to lp_solve.  So the overall user impact
from this change should be positive. \\ |
| xpdf | | PDF import can only be built when the poppler library is pre-installed on the system.
| MySQL Connector/C+\+ | | MySQL connector can only be built when the C+\+ connector is pre-installed
on the system. |
| glibc | glibc is being removed from the product\\ | No impact for user. Developers can not
use getopt() function to parse command line. |
| SVG: librsvg, libcroco, libgsf, gdk-pixbuf, glib, gettext, pango | | SVG using an external
renderer is disabled, thus this new feature for 3.4 is there but creates no visualizations
of embedded SVGs. Work for a replacement is ongoing. |
| libwpd | The libwpd library is being removed from the product. \\ | The WordPerfect filter
("WordPerfect Document (*.wpd)") won't be available anymore. No *replacement* until somebody
will work on a filter extension that can be installed separately |
| fonts (liberation and gentium) | These fonts are being removed from the distribution due
to an incompatible license.\\ | Users may install these fonts to their system, in accordance
with their license.  If they do this, then there is no further user impact. |
| libneon | The neon library is being removed from the distribution due to an incompatible
license.\\ | The neon library is used to for all http based communication including WebDAV.
Without a replacement it is for example not possible to insert an image via an http Url. Work
on a replacement ([118569|]) has started
but we will potentially loose WebDAV support at the beginning. |
