I'm trying to setup a docker file that uses the x86_64 centos:centos7 docker image to cross compile to aarch64. The only problem is I'm missing libgcc_s.so for cross compiling, and I'm not sure why. I also noticed that there were no official glibc-aarch64 so I went with Computational's packages. I've provided my docker file, and any help would be appreciated.
FROM centos:centos7
RUN yum -y update \
&& yum -y install epel-release \
&& yum -y install clang gcc gcc-c++ make wget \
&& yum -y install gcc-aarch64-linux-gnu gcc-c++-aarch64-linux-gnu
RUN yum install -y http://springdale.princeton.edu/data/springdale/7/x86_64/os/Computational/glibc-aarch64-linux-gnu-2.24-2.sdl7.2.noarch.rpm
RUN yum install -y http://springdale.princeton.edu/data/springdale/7/x86_64/os/Computational/glibc-aarch64-linux-gnu-devel-2.24-2.sdl7.2.noarch.rpm
CMD ["/bin/bash"]
I'm not sure on the exact reason why, but gcc-aarch64-linux-gnu and gcc-c++-arch64-linux-gnu were compiled with --disable-shared. This prevents them from building libgcc_s.so. My best guess on why is because the shared library isn't always used and it's more common to use libgcc.a.
The two solutions that I had were to either build libgcc from source, or to copy the libgcc_s.so from another repo with the same version. I ended up extracting libgcc_s.so from libgcc-4.8.5-44.el7.aarch64.rpm.
I have linux MINT 17.3 Kernel 4.4.0-81 all update available. (For different reasons I can't move to newer version of ubuntu/mint)
I have installed FFMPEG via PPA (NOT from compiling the source):
sudo add-apt-repository ppa:jonathonf/ffmpeg-3 -y
sudo apt-get update
sudo apt-get install -y ffmpeg
Then I tried to install libfdk-aac with guide:
https://trac.ffmpeg.org/wiki/CompilationGuide/Quick/libfdk-aac
sudo apt-get install pkg-config autoconf automake libtool
git clone https://github.com/mstorsjo/fdk-aac.git
cd fdk-aac
./autogen.sh
./configure --enable-shared --enable-static
make
sudo make install
sudo ldconfig
But I'm still receive from FFMPEG: "unknown encoder 'libfdk_aac'"
How can I check if "libfdk_aac' is correctly installed and HOW CAN I ACTIVATE / ENABLE the 'libfdk_aac' on FFMPEG?
If is not possible in my situation, and if I'm obliged to remove all ffmpeg and follow this:
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
FFmpeg does not have a "plug-n-play" codec system. If you want to add another external codec you must compile FFmpeg.
Alternatively, you could find a static ffmpeg binary that includes your desired codecs, but this is not a likely option due to the non-free/GPL incompatible situation of the fdk-aac license.
Your best option if you want to use libfdk_aac is to follow the compile guide you linked to. You can even keep the ffmpeg you installed from that PPA because the guide does not interfere with any existing repository ffmpeg.
I am installing Janus WebRTC Gateway in a Ubuntu Machine (14.04 64 bit). I followed the instructions as in the following link:
However, I get the following error when trying to execute janus:
https://github.com/meetecho/janus-gateway (readme.md file)
[FATAL] [janus.c:main:3670] No Janus API transport is available...
enable at least one and restart Janus
Anyone has any idea what the issue might be? I will only use the REST API without WebStockets or RabbitMQ.
I successfully installed Janus on Ubuntu 14 according to the following steps:
sudo apt-get install libmicrohttpd-dev libjansson-dev libnice-dev libssl-dev libsrtp-dev libsofia-sip-ua-dev libglib2.0-dev libopus-dev libogg-dev libini-config-dev libcollection-dev libwebsockets-dev pkg-config gengetopt automake libtool doxygen graphviz git cmake
sudo apt-get install libavformat-dev
mkdir -p ~/build
cd ~/build
git clone git://github.com/meetecho/janus-gateway.git
cd janus-gateway
sh autogen.sh
./configure --disable-data-channels --disable-websockets --disable-rabbitmq --disable-docs --prefix=/opt/janus LDFLAGS="-L/usr/local/lib -Wl,-rpath=/usr/local/lib" CFLAGS="-I/usr/local/include"
make && sudo make install
sudo make configs
Running it by:
cd /opt/janus/bin/
./janus -F /opt/janus/etc/janus/
I had this issue before, I had write a script to install everything just run this
wget https://gist.githubusercontent.com/johnmelodyme/966f474a99b6dd0cf4e7ac19ba4258da/raw/0f1779499c62eeee3e2a577ef641e94e57b71154/janus.sh && sh janus.sh
Hope This Help Much, I believe there are certain dependencies needs to be installation but you missed it. In https://github.com/meetecho/janus-gateway it stated the Dependencies needed, have to be installed without error.
It is because libmicrohttpd version is lower than requirement, Download and install libmicrohttpd manually (dont use yum or apt-get).
With the yum installed version of ImageMagick on the default Amazon EC2 instance I was getting dark thumbnails via rmagick.
How do I get a newer version of ImageMagick on EC2?
Using a combination of the ImageMagick source installation instructions and some instructions from a blog, I got the following to work:
Get rid of the old version
yum remove ImageMagick
Install the dependencies
You will need the appropriate ImageMagick dependencies for whatever graphic types you expect to convert.
yum install wget tcl-devel libpng-devel libjpeg-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel
curl and extract the ImageMagick source
cd ~/
curl -O http://www.imagemagick.org/download/ImageMagick.tar.gz
tar zxvf ImageMagick.tar.gz
Test configuration
cd ImageMagick-xxx
./configure
Confirm configuration
There should be a yes next to all the image types you anticipate needing to convert, if not see the dependencies step above.
Build and install
make
make install
I have been using wkthmltopdf to convert html to pdf documents on-the-fly on my linux web server. The program originally needed X11 or similar X server to run correctly, but through many requests by developers to have this run on servers without GUI, I am pretty sure it runs a virtual X server in the static version. I have been using the static (stand-alone) version of the program and it works great! I would put the executable file in a folder, and run:
./wkhtmltopdf file1.html file2.pdf
However I would like to install this program system-wide. I used the apt-get install wkhtmltopdf (just installed yesterday) and since I am running on a 64 bit system, I also needed apt-get install ia32-libs. After installation I can find the version like this:
wkhtmltopdf --version
output:

wkhtmltopdf 0.9.9

Now when I try to run the program installed via aptitude, I get the following error:
wkhtmltopdf: cannot connect to X server
Does anyone know how I can fix this? I guess this version is missing a virtual X server or something.
or try this (from http://drupal.org/node/870058)
Download wkhtmltopdf. Or better install it with a package manager:
sudo apt-get install wkhtmltopdf
Extract it and move it to /usr/local/bin/
Rename it to wkhtmltopdf so that now you have an executable at /usr/local/bin/wkhtmltopdf
Set permissions: sudo chmod a+x /usr/local/bin/wkhtmltopdf
Install required support packages.
sudo apt-get install openssl build-essential xorg libssl-dev
Check to see if it works: run
/usr/local/bin/wkhtmltopdf http://www.google.com test.pdf
If it works, then you are done. If you get the error "Cannot connect to X server" then continue to number 7.
We need to run it headless on a 'virtual' x server. We will do this with a package called xvfb.
sudo apt-get install xvfb
We need to write a little shell script to wrap wkhtmltopdf in xvfb. Make a file called wkhtmltopdf.sh and add the following:
xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$#"
Move this shell script to /usr/local/bin, and set permissions:
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
Check to see if it works once again: run
/usr/local/bin/wkhtmltopdf.sh http://www.google.com test.pdf
Note that http://www.google.com may throw an error like "A finished ResourceObject received a loading finished signal. This might be an indication of an iframe taking to long to load." You may want to test with a simpler page like http://www.example.com.
This solved the issue for me:
sudo apt-get install xvfb
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltopdf file1.html file2.pdf
I tried to do sudo apt-get install wkhtmltopdf but without any success.
Instead I recommend you try:
Download the latest executable (.11 rc1) :
wget https://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
uncompress it :
tar -vxf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
rename it :
mv wkhtmltopdf-i386 wkhtmltopdf
chmod it to executable :
chmod a+x wkhtmltopdf
place it into /usr/bin :
sudo mv wkhtmltopdf /usr/bin
Just made it:
1- To download wkhtmltopdf dependencies
# apt-get install wkhtmltopdf
2- Download from source
# wget http://downloads.sourceforge.net/project/wkhtmltopdf/xxx.deb
# dpkg -i xxx.deb
3- Try
# wkhtmltopdf http://google.com google.pdf
Its working fine
It works!
I found method to resolve this problem without fake X server.
In newest version of wkhtmltopdf dont need X server for work, but it no into official linux repositories.
Solution for Ubuntu 14.04.4 LTS (trusty) i386
$ sudo apt-get install xfonts-75dpi
$ wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2/wkhtmltox-0.12.2_linux-trusty-i386.deb
$ sudo dpkg -i wkhtmltox-0.12.2_linux-trusty-i386.deb

$ wkhtmltopdf http://www.google.com test.pdf
User felixhummel got very good solution, but repository with utilite has changed.
Expanding on Timothy's answer...
If you're a web developer looking to use wkhtmltopdf as part of your web app, you can simply install it into your /usr/bin/ folder like so:
cd /usr/bin/
curl -C - -O http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
tar -xvjf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
mv wkhtmltopdf-i386 wkhtmltopdf
You can now run it anywhere using wkhtmltopdf.
I personally use the Snappy library in PHP. Here is an example of how easy it is to create a PDF:
<?php
// Create new PDF
$pdf = new \Knp\Snappy\Pdf('wkhtmltopdf');
// Set output header
header('Content-Type: application/pdf');
// Generate PDF from HTML
echo $pdf->getOutputFromHtml('<h1>Title</h1><p>Your content goes here.</p>');
Update to latest wkhtmltopdf version from SourceForge (0.12 as of this writing). It does not need an X Server to run.
Example for Ubuntu 14.04:
$ cd /tmp/
$ wget -q http://downloads.sourceforge.net/project/wkhtmltopdf/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
$ dpkg -x wkhtmltox-0.12.2.1_linux-trusty-amd64.deb foo

Problem is probably in old version of wkhtmltopdf - version 0.9 from distribution repository require running X server, but current version - 0.12.2.1 doesnt require it - can run headless.
Download package for your distribution from http://wkhtmltopdf.org/downloads.html and install it - for Ubuntu:
sudo apt-get install xfonts-75dpi
sudo dpkg -i wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
wkhtmltopdf > 0.11 doesn't have this X-server issue.
So installing 0.12.2.1 on a linux server.
At first install xvfb server:
sudo apt-get install xvfb
Get needed version of wkhtmltopdf from http://wkhtmltopdf.org/downloads.html
Install wkhtmltopdf:
sudo dpkg -i wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
or install with wget
URL='http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb'; FILE=`mktemp`; wget "$URL" -qO $FILE && sudo dpkg -i $FILE; rm $FILE
Install dependency (if needed):
sudo apt-get -f install
Create symblic link in /usr/local/bin/:
echo 'exec xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$#"' | sudo tee /usr/local/bin/wkhtmltopdf.sh >/dev/null
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
Now try below and it should work,
/usr/local/bin/wkhtmltopdf http://www.google.com test.pdf
I just figured out that I can simply move the static executable to the /usr/bin/ directory and execute it from anywhere.
solution for Centos7:
yum -y install xorg-x11-fonts-75dpi \
xorg-x11-fonts-Type1 \
&& rpm -Uvh http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm
We run into this problem inside docker containers and the above install has wkhtmltopdf with patched QT
It is recommended to use at least 0.12.2.1.
Starting from wkhtmltopdf >= 0.12.2 it doesn't require X server or emulation anymore. You can download new version from http://wkhtmltopdf.org/downloads.html
I did follow the instructions here and made wkhtmltopdf work for me but I would like to offer a bit of perspective which I discovered while doing my own little dance with wkhtmltopdf - xvfb.
This is important because the same reason that causes it to throw the infamous cannot connect to X server error is also causing it to run with sever limitations even if you do provide it a X server. These limitations include not being able to take multiple input sources, set header and footers, etc (check the Reduced Functionality section of the manual).
wkhtmltox by itself doesn't require a X11, however it's making use of QT libraries which do. In newever versions of wkthmltox developers made a patch for QT which allows it to run with a X11.
Currently some versions are built against patched QT and some are not. You can check your version by running wkhtmltopds --version. There should be a line at the end saying Compiled against wkhtmltopdf patched qt.
So, to conclude, if you install and use a version that uses the patched libraries it should work on a linux server without the xvfb server, as I can confirm.
Pay attention: your file could be wkhtmltopdf.sh or wkhtmltopdf, check it on second step
You must copy it into directory : /usr/local/bin, make sur it's executable and add symlink of wkhtmltopdf.sh like :
1- the command :
sudo apt-get install wkhtmltopdf
2 - insert the binary in directory /usr/bin so the browser can't have permission to execute in this directory.
You must copy the wkhtmltopdf.sh to directory /usr/local/bin cause the browser have permission in this directory like:
sudo cp /usr/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf.sh
3 - After make sur the binary have permission of execution like :
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
4 - so now you can test, it's work like:
/usr/local/bin/wkhtmltopdf.sh http://www.google.com google.pdf
it make download the pdf in the current directory in your terminal
5 - Optional
now you can add symlink in your directory /usr/local/bin like
ln -s /usr/local/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf
Just tell the Qt backend to not use X:
QT_QPA_PLATFORM=offscreen wkhtmltopdf <input> <outfile.pdf>
Download file from this link
Extract it and move executable file(/wkhtmltox/bin/wkhtmltopdf) to /usr/bin/
Rename it to wkhtmltopdf if current name is not wkhtmltopdf. So that now you have an executable at /usr/bin/wkhtmltopdf
Set permissions: sudo chmod a+x /usr/bin/wkhtmltopdf
Install required support packages. sudo apt-get install openssl build-essential xorg libssl-dev
Now, check with wkhtmltopdf http://www.google.com test.pdf
hint: detail information from this link
Just install a version 0.12.4 or higher. This seems to solve the problem.
See How can I install the latest wkhtmltopdf on Ubuntu 16.04?.
If you config wkhtmltopdf for Rails or Somethings in Centos, you can follow these step bellow:
Go to https://wkhtmltopdf.org/downloads.html and copied the link of rpm file.
In centos server bash.
wget link_of_wkhtmltopdf_rpm.rpm
rpm -ivh link_of_wkhtmltopdf_rpm.rpm
which wkhtmltopdf
=> You will get path of wkhtmltopdf.
Setup for wicked_pdf or pdfkit with path in step 4.
This is sample config with wickedpdf. config/initializers/wicked_pdf.rb
if Rails.env != "production"
path = %x[which wkhtmltopdf].gsub(/\n/, "")
else
path = "path_of_wkhtmltopdf_in_step_4"
end
WickedPdf.config = { exe_path: path }
Restart server.
DONE.
For 64-bit Use:
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
sudo mv wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf
sudo chmod +x /usr/bin/wkhtmltopdf
