I want to work on an Xorg server module and I am wondering how I can reload the module at runtime.
Also, maybe someone can give me some good tips about doing this (because I never have worked with Xorg server code before).
Esp. I am running the Ubuntu version of Xorg 7.5 (if that matters much -- does it?).
What I want to do specifically is to implement mouse wheel acceleration in XInput.
I thought about adding a new option for this which can be set somewhere (I think xorg.conf is not anymore the place where you do the XInput configuration; where is it now and what would be the best way to introduce a new setting, i.e. MouseWheelAccel or sth like this?).
And then of course to implement the actual acceleration. As mouse wheel events are just like button press events, I thought of just increasing the rate of firing such events. How to implement this is actually really the minor problem. (I am actually thinking about it as being trivial. Let's see if the Xorg code allows it to be so simple...)
So far, I have done this:
Reports:
at Launchpad/(K)Ubuntu
at Ubuntu Brainstorm
at Ubuntu forums
at KDE
at Freedesktop/Xorg
Check out Xorg via Git, prepare for compiling, and get the XServer code. Basically this:
...

I want to train my existing tesseract model for a new character. I already tried the tutorial on
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#lstmtraining-command-line
(Fine Tuning for ± a few characters) (I'm using a MAC)
But it does not work. If I evaluate (even on the training data), it can't recognize the ± character.
I installed:
tesseract 5.0.0-alpha-447-g52cf
leptonica-1.78.0
libgif 5.1.4 : libjpeg 9c : libpng 1.6.37 : libtiff 4.0.10 : zlib 1.2.11 : libwebp 1.0.3 : libopenjp2 2.3.1
Found AVX2
Found AVX
Found FMA
Found SSE
Found libarchive 3.4.0 zlib/1.2.11 liblzma/5.2.4 bz2lib/1.0.6
via:
I cloned the following GitHub repositories to my Desktop and installed tesseract:
https://github.com/tesseract-ocr/tesseract.git
https://github.com/tesseract-ocr/langdata_lstm
https://github.com/tesseract-ocr/tessdata_best
My installation was as follows:
Install:
brew install automake autoconf autoconf-archive libtool
brew install pkgconfig
brew install icu4c
brew install leptonica
brew install gcc
Run
ln -hfs /usr/local/Cellar/icu4c/60.2 /usr/local/opt/icu4c
Go into the cloned tesseract folder.
~/Desktop/tesseract
Run autogen.sh:
./autogen.sh
Install dependencies:
brew install cairo pango icu4c autoconf libffi libarchive libpng
export PKG_CONFIG_PATH=\

(brew --prefix)/opt/icu4c/lib/pkgconfig:\
(brew --prefix)/opt/libffi/lib/pkgconfig:\
(brew --prefix)/opt/libpng/lib/pkgconfig
(IF SOME ARE ALREADY INSTALLED, use reinstall instead of install)
Run configure:
./configure
Install tesseract:
make
sudo make install
Install training-tools:
make training
sudo make training-install
After, I inserted eng.traineddata from tessdata_best to tesseract/tessdata
My training code is as follows:
# GENERATE TRAINING DATA

I don't know why this code does not produce the result I expect. I tried to train for a new font and the above code works. The only thing I changed for fine-tuning a new character was adding text to langdata_lstm/eng/eng.training_text:

If the eng.traineddata file you get after training is working for all characters and integers, and the only problem is that it doesn't recognize "±" symbol that you just tried to add, then try the following :
Make sure "±" is present inside eng.charset_size=xx and
eng.unicharset files.
In the engdata_lstm/eng/eng.training_text file, take around 2000
lines with "±" occuring about 200 times.
--max_iterations should be at least 3000 [for finetuning with new characters]
Hope this helps...
And thanks, your question helped me out.. :)
When building VLC on Ubuntu 18 using the following configure invocation:
First I obtain the source like so:
% git clone git://git.videolan.org/vlc.git
% cd vlc
% ./bootstrap
Then I build like so:
make clean
./configure --disable-lua --disable-swscale --disable-alsa --disable-chromecast --disable-fontconfig
The build fails like so:
codec/jpeg.c: In function ‘DecodeBlock’:

Any ideas what I did wrong here? It seems like the module in question should fail to build in this case as I disabled fontconfig.
Libfontconfig is in fact installed:

libfontconfig1 is already the newest version (2.13.0-5ubuntu3).

root#fuzzbot:~/vlc-3.0.4#
Additional ideas:
I tried in vain to find VLC's official bug tracker for this kind of thing. I found bug trackers for literally every subproject of VLC but the main project that I am trying to build. If anyone knows the proper channels to ask the VLC people about this, let me know.
Additionally if the admins feel that this question better fits on serverfault, or AskUbuntu, feel free to move it. As far as I can tell this is a little too automake specific to be serverfault's bag, and I don't think the issue is unique to Ubuntu, as the official VLC wiki specifies no specific instructions for Ubuntu.
I don't really need all the plugins for my use case. If doing any further --disables in my configure invocation will help, I'm willing to try it.
The errors indicates a problem with linking against "some" xml-library.
most likely libxml2, which you probably have not installed.
./configure is supposed to detect any missing library and prevent your build from failing, but there might be a bug in the configure script itself.
Anyhow, since you are on a Debian-based distribution, you could simply install all the packages that are required to build the official Debian (or Ubuntu) package. (Your personal build might have additional dependencies or lack some of the dependencies of the official package, but it is usually a good starting point).
apt-get build-dep vlc
If you are getting an error like E: You must put some 'source' URIs in your sources.list then you should add deb-src entries to your apt sources-list, e.g. using
find /etc/apt/sources.list /etc/apt/sources.list.d/ \
-type f -name "*.list" -not -name debsrc.list \
-exec echo sed -e 's|^deb |deb-src |' {} + > /etc/apt/sources.list.d/debsrc.list
I followed your post on vlc forum to this SO post.
As people there suggested the libass is the problem, thus I added the option to disable it. Now the configuration command looks like:
./configure --disable-libass \
--disable-lua --disable-swscale --disable-alsa --disable-chromecast --disable-fontconfig
The compilation proceeded without the previous fontconfig error. However it hits a different error:
....upnp....: undefined reference to `pthread_rwlock_wrlock'
A google search turned up another vlc forum thread. People suggesting turning off upnp. Configured it again by adding:
--disable-upnp
Then hit another error:
/libavcodec.a(fft.o): relocation R_X86_64_PC32 against symbol `ff_cos_32' can not be used when making a shared object; recompile with -fPIC
Another google search suggests to turn off chromaprint, adding yet another option:
--disable-chromaprint
Eventually it finishes with a success!
Before running the long configure command at the beginning of this post, I also tried building 3.0.7.1 but hit a problem with missing a liveMedia.hh file. In case anybody else is doing the same, here is the list of packages installed though not all of them are required since disabled a few features on the configure command line:
apt-get install git build-essential pkg-config libtool automake autopoint gettext
apt-get install subversion yasm cvs cmake ragel
apt-get install gperf
apt-get install openjdk-8-jre-headless openjdk-8-jdk-headless
apt-get install ant
apt-get install python3-pip
pip3 install meson
apt-get install nasm
apt-get install protobuf-c-compiler
apt-get install protobuf-compiler
apt-get install libpthread-stubs0-dev
apt-get install libasound2-dev liblivemedia-dev livemedia-utils
Summary
Use the videolan unix compile wiki page as a guide for steps below.
Install supporting packages as the list above shows.
Run cd contrib && mkdir native && cd native && ../bootstrap && make to build libraries.
Run the very long configure command:
./configure --disable-libass \
--disable-lua --disable-swscale --disable-alsa --disable-chromecast --disable-fontconfig \
--disable-upnp --disable-chromaprint
Run make.
I was excited to use bash on windows but quickly ran into an issue. I am trying to install build-essential, but I get a dependency issue. Upon trying to resolve with sudo apt-get install -f, I run into another error that doesn't make much sense. I've tried update and upgrade, but that didn't work either. F

build-essential is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

E: Sub-process /usr/bin/dpkg returned an error code (1)
Full log of what led to the error in Bash on Ubuntu on Windows terminal is here:
https://pastebin.com/dq2D2Gtz
I don't have a solution, but I see the root of the problem. It seems to have to do with case sensitivity on the filesystem. The package for linux-libc-dev puts two copies of a file in /usr/include/linux/netfilter_ipv6 with only a difference in case; ip6t_HL.h, and ip6t_hl.h. After placing ip6t_HL.h, it attempts to rename ip6t_hl.h.dpkg-new to ip6t_hl.h. The system call to rename the file fails, claiming that ip6t_hl.h already exists
On a "real" linux system, ip6t_HL.h and ip6t_hl.h would clearly be different files. Under WSL they probably had some strange incompatibilities to work out between NTFS's default case insensitive FS and unix's default case sensitivity.
You can duplicate the problem by hand e.g., with
echo hi > foo.H
echo hi > foo.h-new
mv foo.h-new foo.h
mv: cannot move 'foo.h-new' to 'foo.h': File exists
strace output:
rename("/usr/include/linux/netfilter_ipv6/ip6t_HL.h.dpkg-new", "/usr/include/linux/netfilter_ipv6/ip6t_HL.h") = 0
open("/usr/include/linux/netfilter_ipv6/ip6t_hl.h.dpkg-new", O_WRONLY) = 10
fsync(10) = 0
close(10) = 0
rename("/usr/include/linux/netfilter_ipv6/ip6t_hl.h.dpkg-new", "/usr/include/linux/netfilter_ipv6/ip6t_hl.h") = -1 EEXIST (File exists)

) = 199
I had the same problem. Like #dmattp I found that it this is because, unfortunately, the package contains some (header) files with names that are distinct only by letter case, and that the wonderful WSL file system has an inconsistency regarding case sensitiveness.
Here is a workaround, assuming that the package has name linux-libc-dev_3.13.0-123.172_amd64.deb:
cd any-temp-dir
apt-get download linux-libc-dev
ar x linux-libc-dev_3.13.0-123.172_amd64.deb
tar xJf data.tar.xz # ignore all erors like ./usr/include/linux/netfilter_ipv4/ipt_ttl.h: Cannot open: Input/output error
tar cJf data.tar.xz ./usr
ar rcs linux-libc-dev_3.13.0-123.172_amd64-patched.deb debian-binary control.tar.gz data.tar.xz
sudo dpkg -i linux-libc-dev_3.13.0-123.172_amd64-patched.deb
It says dependencies aren't being installed, so try:
sudo apt-get install linux-libc-dev
If that doesn't work try:
sudo apt-get install --reinstall build-essential
This will reinstall build-essential. Hope this helps, cheers!
I installed LibreOffice on a server with a shell script using the following
sudo -S dpkg -r LibreOffice_5.1.1.3_Linux_x86-64_deb/DEBS/*.deb
Now I would like to change to a different version and am attempting to uninstall the previous version by using:
sudo -S dpkg -i LibreOffice_5.0.6.3_Linux_x86-64_deb/DEBS/*.deb
which yields the error
dpkg: error: you must specify packages by their own names, not by
quoting the names of the files they come in
After doing some research I found this thread and it seems I will need to call the dpkg with the name of the actual debian files, but doing dpkg -r libreoffice results in the error
dpkg: warning: ignoring request to remove libreoffice which isn't
installed
I have also tried using sudo apt-get remove libreoffice-core, which does not seem to be successful. Is there an automated way to remove all of the installed .deb files so that I can safely install the new version?

Use dpkg-query -l to get a list of installed packages. You can also search the list with dpkg-query -l 'libre*' for everything beginning with 'libre'.
You can then use the displayed package name to remove or purge them with dpkg.
Using dpkg --remove PackageNameHere will let configuration files untouched and delete only the binaries.
With dpkg --purge AgainYourPackageNameHere you would delete everything regarding the package.
we can also use dpkg-query - W to list the installed packages.
For example to search for installed sqlectron
$>dpkg-query -W 'sqlec**'
sqlectron 1.37.1
then you can delete the package using dpkg -r|--remove 'package-name' or dpkg -P|--purge 'package-name' command.
We are trying to install openvpn 2.3.5 on freeBSD. Build collapses with : "don't know how to make .gitignore".

Anybody out there have this issue? What might be the cause?
Are you installing OpenVPN from source?
The intended way to install from source is to compile a port (make -C /usr/ports/security/openvpn install clean).
Or you can just install a binary package: pkg install openvpn.
