Here is the deal ......... M$ builds windows and they know exactly where
"THEIR" libraries are. Well, they may just need to check the registry
to for the library. Further, unlike OO, they DO NOT depend on third
party libraries.
But with Linux, there are hundreds of distributions, each of which may
place the required libraries in different places. Further, if one mounts
nfs share and runs OO over the network, there may be different
operating systems running the same program. In this case searching for
libraries is valid. One may remove libraries inbetween OO invocation,
which would not be detected if OO checks for the libraries every time.
Here is the code from soffice script that searches for mozilla
libraries.
add_moz_lib=
for moz_lib_path in
$MOZILLA_LIBRARY_PATH /usr/lib /usr/lib/mozilla /usr/lib/mozilla-firefox
/usr/lib/mozilla-thunderbird /opt/mozilla/lib /opt/MozillaFirefox/lib
/opt/MozillaThunderbird/lib; do
test -f $moz_lib_path/libnss3.so && add_moz_lib=":$moz_lib_path"
&& break;
done
Every thing said and done, I am NOT defending the slowness of OO .......
but there is a valid reason for its slowness. I am sure some programmer
will be able to overcome the slowness with appropriate changes. Perhaps,
we should file a bug report and vote for it.
