I recently installed the Scilab 6.1.0 on my Ubuntu 18.04 virtual machine on my windows pc. I am able to use the editor but cannot seem to load the Fossee Optimisation Toolbox. It installs successfully but shows the following error when restarting and trying to load the toolbox. I have already tried reinstalling Scilab and ubuntu. Can someone tell me how to resolve this?
atomsLoad: An error occurred while loading 'FOT-0.4':
exec: error on line #61: "link: The shared archive was not loaded: libquadmath.so.0: cannot open shared object file: No such file or directory"1
FOT is built using gfortran, and the missing library is one of its libraries. Scilab uses also gfortran and is including the corresponding libraries. But there is likely a version number mismatch, i.e. FOT has been built with a more recent version of gfortran. Installing a system wide gfortran with sudo apt-get install gfortran will probably install the version you need.

I am following this tutorial. I already have .fastq files. I want to install ea-utils.
My setup is Ubuntu 18.04 bionic, via Oracle VM Virtual Box.
In terminal, I entered the command:
>>>sudo apt install ea-utils
E: Unable to locate package ea-utils
First, I installed latest Ubuntu updates via. Software Updater.
Then,
>>>sudo apt-get update
E: Some index files failed to download. They have been ignored, or old ones used instead.
Still throwing an error:
>>>sudo apt-get install ea-utils
Second command said: E: Unable to locate package ea-utils.
You cannot install it using Git-Bash. Git-Bash is not a Linux environment (apt-get is a Linux utility that can be used in a Linux environment). Git-Bash is a subset of the MSYS (or MSYS2, not sure) collection of open source tools compiled for Windows
What you can try is
build your own version of ea-utils for Windows. build guide - I will elaborate if required
check if there are any precompiled binaries for it
Expanding on building/compiling your own binaries of programs
Normally a program is written in a programming language (e.g C/C++, Java) that humans can read. These are plain text files.
That is compiled into something computers can read
This compiled file is executable on the platform which it is compiled for - ends in .exe for Windows
This executable file is distributed as a 'precompiled binary' that is copied into (usually) C:\Program Files by the installation procedure
But things change in the world of open source software
You are given the original files of code written in a programming language
You use a compiler combined with other libraries to compile it into an executable file
MinGW is a collection of tools, including the C/C++ compiler for Windows
GSL is a library that provides some other code that ea-utils depends on for the compilation of the binaries
General instructions for building
(Sorry I cannot test these. I do not use Windows any more)
Install MinGW - accepting the defaults should work fine
Install GSL - try the link that says Setup (again, accept defaults)
Unzip the file you downloaded earlier from ea-utils' GitHub
Open command prompt
cd into the unzipped folder
(based on instructions on their wiki) make
make test
Since your updated question is based on using Ubuntu 18.04 in a VM and you there is still an error, I suggest trying
sudo apt-get update
sudo apt-get install ea-utils
Commonly, software in the Linux word is distributed as "packages" - e.g ea-utils. The first command contacts Ubuntu's repositories (they serve the packages) and generates a list of all the available packages.
That should fix the error of ea-utils not being found.
Following the constant errors being thrown,
Download the .deb file 64-bit version or 32-bit version according to the virtual machine you are running. Open it inside the virtual machine, and follow the onscreen instructions.
I have installed the following
C:\MinGW
C:\msys
C:\GTK
But python searching for the files in site packages and throwing the error as:
OSError: cannot load library libcairo.so.2: error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library
This issue happening in installation of weasyprint packages.
Installing GTK+ didn't work for me.
I solved this problem using UniConverter2.0.
My environments is
Python 3.7
Windows 10 x64
Install uniconvertor-2.0rc4-win64_headless.msi,
Find the "dll" sub-directory under the UniConverter installation path.(In my case, C:\Program Files\UniConvertor-2.0rc4\dlls)
Add this "dll" path to the system path.
Close VSCode and reopen the project.
Try to run your code again.
Enjoy!
In my experience with this issue Windows 10 (64-bit) with Python 3.5.1, it can be either due to duplicate libraries in other directories seen by PATH that don't work or the libraries that you installed just aren't compatible with your OS/Python bit version.
I suggest installing an older version of GTK+ (I used 3.10.4) using the links provided in the WeasyPrint documentation instead and see if the error persists. I had the issue on a newer build of GTK+. The version of GTK+ installed with MSYS2 gave the same error.
Edit: I found the post where I found the previous version of GTK that I was using but it gave an annoying warning about the cairo version being unstable:
See this post.
Edit 2: To get rid of the cairo version stability warnings, I managed to get a newer version of Cairo using the GTK3-runtime-3.22.8 (Link to git downloads as per WeasyPrint docs)
Remember to uninstall all current GTK+ implementations first. You might get a warning saying that the version of cairo can cause issues but I haven't been able to locate a newer version of cairo that works in windows, let me know if you find one.
I'm working on Raspberry Pi Raspbian GNU/Linux 8 (jessie).
I have installed
-Tesseract 4.00.00alpha
- leptonica-1.74.1
-libjpeg 6b (libjpeg-turbo 1.3.1) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
-OpenCV 2.4.11
Installed openalpr but I am not able to use it, only I can do is watch man alpr. Any other thing I try to do with this throws an error.
alpr: error while loading shared libraries: libopencv_xphoto.so.3.1: cannot open shared object file: No such file or directory
I thought this was because I didn't have OpenCV3.1.0 installed, but installed it and the error is still there.
This file is inside /usr/local/lib, maybe I have to put it somewhere else but I don't know where, or do I have to reinstall Openalpr to get compile all of this from scratch?
Greetings!
Made it work..
After installing OpenCV3.1.0 just had to run sudo ldconfig command.
And thats all.
Cheerio,
I am trying to use Assimulo 2.9. on a Mac OS X. For that I downloaded and installed sundials via cmake by creating a builddir to the Download file and ../Downloads/sundials-2.7.0 running
$cmake ../Downloads/sundials-2.7.0
$make
$make install
This should install everything in /usr/local.
It gives me no error warning when doing this. But when I am trying to use assimulo in python, following error message occurs:
from .sundials import IDA, CVode
ImportError: No module named sundials
Any suggestions?
Thank you very much.
The trick was to install everything through homebrew and get the missing sundials.so file. It seems that the current assimulo-2.9 distribution on pypi does not provide this shared object library and therefore triggers this error message.
I got the same error, in Anaconda(Ubuntu 18.04). I installed pyfmi first, and then installed the dependencies (assimulo, sundials) according to the error message. After everything was installed, the pyfmi was not working by running an fmu example.
But i uninstalled all the related software. Then i reinstalled everything with certain order. I found the order of installation matters, which are: sundials --> assimulo --> pyfmi.
Everything is good now.
I tried to install a climate modelling programm (RegCM) for which I used Ubuntu on VMware Workstation, GNU fortran compiler and Open MPI.
Like suggested [https://gforge.ictp.it/gf/download/docmanfileversion/35/758/Install_RegCM4.3.pdf] I installed the GNU fortran compiler, Open MPI, unpacked RegCM Version 4.4.5 and configured RegCM (./configure CC=gcc FC=gfortran).
In 'sudo make' the Error
'Error: Can't open included file 'mpif.h''
appears. In 'RegCM-4.3.5.8/Main/mpplib' which was searched is no file with that name but one can be found in 'openmpi-1.10.2/ompi/include'. Just to give it a try copied 'mpif.h' in the searched directory.
It worked but now a new Error appeared:
'Can't open included file 'mpif-config.h''
which again can be found in 'openmpi-1.10.2/ompi/include'. Again copied the same Error arised with another file.
I also tried a older Version of RegCM (4.3) with the same effect.
Any suggestions on this?
? Which version of Ubuntu are you using ? Like "Ubuntu 16.04 - amd64".
mpif.h, mpif-config.h : sudo apt-get install libopenmpi-dev
Note : RegCM-4.3.5.8 is buggy. No luck with '4.3.5.8' here, any contemporary OS. RegCM-4.5.0 → RegCM-4.5.0.tar.gz
https://gforge.ictp.it/gf/download/frsrelease/252/1580/RegCM-4.5.0.tar.gz builds with no errors : Tested with Ubuntu 16.04 - 64bits and PCLinuxOS2016 -32bits.
