I am working with the exiv2 library. I currently faced an issue, and i can't find my way out of it. Here is the issue.
I installed the exiv2 library. When I try to run it, the following error is given.
exiv2: error while loading the shared libraries: libexiv2.so.26: cannot open shared object file: No such file or directory
But, when i open the /usr/local/lib folder, it exists there. Again when I try to locate the library using the ldd command, the command cannot locate it!
Can anyone help me to find what is going on there? Thanks in advance!
If not how to uninstall the whole library and reinstall it?
I had a similar problem when using the sources for installing.
You can remove the built files with sudo make uninstall from inside the sources folder of exiv2.
The solution to my problem was to simply use the package from the Ubuntu repository: sudo apt install exiv2 libexiv2-dev.
Hopefully this will help you too.

install Lattice Diamond 3.10 on my computer with Manjaro 17.1 and everything works correctly just because of a problem. The programming tool does not work, when I try to execute it I get a window with a message:
"can not load library:
/usr/local/diamond/3.10_x64/bin/lin64/toolapps/libdvmapp.so:
(libusb-0.1.so.4: the shared object file can not be opened: the file
does not exist or the directory)"
already downloaded and I put the library in the corresponding directory but still does not let me run it
Any suggestions to solve it, I would appreciate it very much
Thank you
I had to install the following libraries:
libusb 1.0.21-2
libgusb 0.2.11-1
libusb-compat 0.1.5-1
libusbmuxd 1.0.10+13dc724e70-1
And the programming tool works
I already had all of the dependencies listed by Cristian in place. I had to install libusb-dev and it worked.
sudo apt install libusb-dev
I am trying to get PHPDocumentor running on a local XAMPP installation.
Sadly I having a hard time doing it using package managers.
Some basic questions about package managers first:
How do I know where to install a package? For example: I installed PHPDocumentor using Composer. I go to my C:\xampp\htdocs\ and run a command:
composer require "phpdocumentor/phpdocumentor:2.*"
This installs phpdocumentor in a " vendor" folder in xampp\htdocs\
Is this the correct path to install all these packages or is there a default dir to install this?
If I want to uninstall the packages, do I simply delete the "vendor" dir?
After the installation I ran PHPdocumentor and got an error:
Unable to find the dot command of the GraphViz package. Is GraphViz
correctly installed and present in your path?
To resolve this, I tried the following:
Installed the package graph/graphviz while my pointer was in the htdocs-folder and pointed a path to the folders:
C:\xampp\htdocs\vendor\graph\graphviz
...graph\graphviz\src
...graph\graphviz\tests
None of the above solved the problem.
According to this link I have to add the \graphiz\bin directory to path, but there is no "bin" dir?
Can anyone help me out with this?
Best regards,
Abayob
Unable to find the dot command of the GraphViz package. Is GraphViz correctly installed and present in your path?
The steps to resolve this error are:
download zip from https://graphviz.gitlab.io/_pages/Download/Download_windows.html
extract to c:\some\where\graphviz
add c:\some\where\graphviz\bin to your environment variable PATH
run phpdoc
I don't like to have 184MB of usefull stuff on my PC just to run the 'dot' command?
Yes, its a lot of stuff. A more lightweight solution would be nice.
I'm trying to install Armadillo (and thus also BLAS and LAPACK) on a linux server for which I do not have root permission. I have jumped through a few of the first hurdles, but I am getting an error:
/usr/bin/ld: cannot find -llapack
This question addresses the same problem, with the solution being to install
liblapack-dev
liblapack3
libopenblas-base
libopenblas-dev
The problem is the only way I've found to do this online is by doing something like sudo-aptget install or yum install. Both are not allowed on the server I use. I can download binaries and install them locally - that is it.
My question is: how can I install these packages without the above permissions and get on my way to using Armadillo?
I'm using Centos linux, if it helps.
Since you do not have root permissions, the best way is to download and build LAPACK and BLAS. You can download the source code from netlib.
Description of installation instructions can be found here and here.
The basic steps are:
Unzip and tar the file.
Copy and edit the file LAPACK/make.inc.example to LAPACK/make.inc.
Edit the file LAPACK/Makefile
type make.
Similarly you can download and build BLAS.
I am trying to install the zeroMQ for my server(redhat 7). Here is what I did:
1) download the zeroMQ and unpack it.
2) navigate to the file where I put the zeroMQ and run the commands below:
./configure
make
make install
Now I can find two head files in /usr/local/include: zmq.h and zmq_utils.h and five files in /usr/local/lib: libzmq.a libzmq.la libzmq.so libzmq.so.4 libzmq.so.4.0.0.
Then I try to code like this:
#include <zmq.h>
...
void * context = zmq_init(1);
But I get this error message: undefined reference to `zmq_init'
I find that the include works well but it cant find 'zmq_init', so maybe it's the problem of lib files. But all of the lib files have been in /usr/local/lib, right?
What should I do?
Problem solved:
I got that error message because the lib files are in the directory: /usr/local/lib
What we need to do is to create a file named local-lib.conf under the directory /etc/ld.so.conf.d/ and write /usr/local/lib in it. The name of the file is not important but its extension must be .conf.
Then, we must navigate to /etc/ld.so.conf.d/ and type this command: sudo ldconfig
I tried the fix provided by #Yves above, but that didn't work out for me so here's another way for Debian/Git installations.
Alternative fix:
I have faced this issue on a Docker container which was occuring due to the libzmq/czmq which was installed by cloning the git repo.
The problem is that the shared libraries when installed using git are located in the /usr/local/lib folder instead of /usr/lib/ where usually, in my case a C/C++ program looks for shared library files.
I fixed it by copying all files from /usr/local/lib folder to/usr/lib/ using the command
$ sudo cp -R /usr/local/lib/* /usr/lib
This was for a RPi/ Ubuntu-16.04 docker, the command or location of the files may vary depending on your OS.
The latex file is giving the following error:
! LaTeX Error: File `datetime.sty' not found.
Here is the Latex code: \usepackage{datetime}
Am I missing something?
I am using Debian 3.1 Linux Machine.
I don't use Debian myself, but if I look it up, Debian contains it in the package 'texlive-latex-extra'. If you installed LaTeX via the packet-manager of debian (I think so) the command 'apt-get install texlive-latex-extra' executed as root should install you the needed file. Alternatively you can use a graphical package-manager to install the package.
If your LaTeX Distribution does not load the package automatically, you can try to install it manually according to the readme file here: http://www.ctan.org/pub/tex-archive/macros/latex/contrib/datetime/ Edit: http://www.ctan.org/pkg/datetime
Yes, you are missing the datetime.sty file; you are probably missing the whole package too. What system are you using for managing your (La)TeX installation ? If you tell us you may get more specific advice than I can give.
You need to get the datetime package from CTAN or one of its mirrors and install it into your local texmf tree. Your LaTeX manager will do this for you. You may also be able to configure your LaTeX manager to automatically download and install packages the first time they are requested.
