I am trying to install Octave on OS X. When executing brew install octave I get the following error:
octave: A LaTeX distribution is required to install.
You can install MacTeX distribution from:
http://www.tug.org/mactex/
Make sure that "/usr/texbin", or the location you installed it to, is in
your PATH before proceeding.
I downloaded and installed MacTeX but it is still not working :(
How can I fix this?
If you want to avoid the MacTeX dependency you can install Octave with brew as follows:
brew install octave --without-docs
"Make sure that "/usr/texbin", or the location you installed it to, is in
your PATH before proceeding."
This message may be the hint of the answer for you.
You need to set the PATH so that the Tex could be called from anywhere in your system.
Adding the following line in the .bash_profile may fix it.
export PATH=$PATH:/usr/texbin/
The reason why the texlive command does not work have also same cause on this.

I am trying to setup a MySQL server using CentOS (No GUI) and I need to switch to OpenSSL instead of YaSSL in order to have access to the encryption tools.
The issues happen when runing the cmake. At first I got the error that cmake was not able to find boost, I fixed this adding the parameter -DWITH_BOOST.
The cmake line is as follows.
cmake . -DWITH_READLINE=ON -DWITH_SSL=system -DWITH_BOOST=/usr/local/src/mysql-5.7.20/boost/
After the adjustment I ran again the CMAKE the I got several errors.
SSL Error, cmake can not find the OpenSSL files. I checked if the library was installed, I also downloaded the tar.gz file and decompress it and pointed the cmake to the folder, none of this worked.
Can not find NUMA libraries, again I checked and it is installed, at this point I ran the system update to check for everything but this did not solve the issue.
Can not find the ncurses, the same thing, is on the system but for some reason cmake is not able to find those.
Can not fin libaio, I didn't have this one installed, I installed, ran cmake again, and again cmake was not able to find it.
I been looking around, trying to figure out all this issues, I've been joining information from different websites but still not able to figure out this.
Thanks ahead to everyone for the help.
You're facing the dependencies hell with MySQL. If you don't really need to compile from the sources, you still can install with the RPM which is much easier. The RPM method is described here : https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/
As you're asking a ready-to-go install from the sources, this is what I just did and it worked, on a fresh CentOS 7.4 minimal, 2 vcpus 3Gb :
yum group install -y 'Development Tools'
yum install -y cmake ncurses-devel curl
curl -Ovk https://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.20.tar.gz
tar zxf mysql-5.7.20.tar.gz
cd mysql-5.7.20
cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=$HOME/boost -DENABLE_DOWNLOADS=1
make -j2
make install
After that you need to configure it, add the startup scripts, and of course secure it. Here are some additional docs :
http://howtolamp.com/lamp/mysql/5.6/installing/
https://dev.mysql.com/doc/refman/5.7/en/mysql-secure-installation.html
Perhaps try make clean; cmake clean; ldconfig then run your cmake command. Sometimes the system can't find the shared libraries, and ldconfig refreshes the library search path. This helped once when I was compiling something (emscripten?) which required a lot of libraries which I was installing as compilation errors arose.
The make clean; cmake clean will ensure that the compiler isn't looking at the old library search path when you recompile.
I am running raspbian on a Raspberry-Pi 2 B. I am trying to install the instrument-control package in octave 3.6.2.Initially I got a mkoctfile missing error:
Installing octave package in ubuntu http://ubuntuforums.org/showthread.php?t=955385
With 'sudo apt-get install octave-pkg-dev' this problem was solved.
However, when I try to install the instrument-control package in octave with: 'pkg install -forge instrument-control' nothing is happening, the command prompt underscore is just flickering as if it is processing something, but nothing happens for at least half an hour (I didn't try longer). I tried running octave as superuser, but the same thing happened.
I would very much appreciate if someone could help me out on this.
NB This is my first post here, and am not a super-experienced computerist so please tell me if I need to provide more information in any form.
It turned out that it actually takes longer than 30 minutes to compile all the necessary files, so octave is actually doing something. You just have to wait longer. When using -verbose this becomes more clear.
The downloading process might be hanging.
As a workaround, you can download the instrument-control package there.
Put it in your directory on the raspberry.
And then, in octave launched from the same directory, issue
pkg install instrument-control-0.2.1.tar.gz
I installed latest Octave on Ubuntu 14.04 machine. However, when I tried to run imread command, it showed the following error message:

Can someone please suggest how to solve it?

Following these steps worked for me [Author: Christoffer Cronström (hymyly)]:
Install the dev packages needed to build octave.
sudo apt-get build-dep octave
Get the official source package. Do this in a clean directory, because it will get polluted.
cd ~/some/suitable/directory
apt-get source octave
Build it. This took roughly an hour for me.
cd octave-3.8.2
dpkg-buildpackage
Either run it from the build directory:
./run-octave
...or most preferably install it over the official octave:
cd ..
sudo dpkg --install octave_3.8.2-4_amd64.deb
From: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1372202
How did you instal Octave? The error suggests that you're missing GraphicsMagick C++ interface (package libgraphicsmagick++3) but
if you installed Octave from Ubuntu's package manager you should not have had this problem; * if you compiled it yourself, Octave should have disabled imread completely and you'd have a very different error message.
So my guess is that you build it yourself, either with:
your own build of GraphicsMagick++ which are not being loaded anymore, you may need to add their path to the dynamic linker load path (either on /etc/ld.so.conf.d./graphicsmagick or define LD_LIBRARY_PATH);
the libraries from the package manager which you have since accidentally removed (since you did not install Octave from the repositories, your package manager will not know that libgraphicsmagick++ is installed for a reason).
Either way, the solution is easy. Install Octave from Ubuntu's package manager. One of the main reasons package managers exist is to avoid this type of problems, i.e., missing dependencies.
I am currently using the Macbook pro with OS 10.9.
And I was trying to install octave to my mac when I found that I have to install gnuplot before I could use the plot in the octave. So I try to install gnuplot using the homebrew. However,the brew got stuck when trying to install the gd, because China's network fails to link to the site https://bitbucket.org/libgd/gd-libgd/downloads/libgd-2.1.0.tar.gz
So I use goagent to download the package via chrome and try to manually install the package and try to link it using brew by the instruction from https://github.com/mxcl/homebrew/wiki/FAQ
And after make install, when I try to use:
brew link libgd
the brew prompt error message:
Error: No such keg: /usr/local/Cellar/libgd
And I followed exactly the process in the FAQ diy.
$ tar -xvf l-ibgd-2.1.0.tar.gz
[snip]
$ cd libgd-2.1.0
$ brew diy
-DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/libgd/2.1.0
$ ./configure --prefix=/usr/local/Cellar/libgd/2.1.0
[snip]
$ make && make install
[snip]
$ brew link libgd
Error: No such keg: /usr/local/Cellar/libgd
The configuration and installation are without any error. Any suggestions? Thx a lot!
There are several things wrong here, and I'm not sure whether they are Homebrew bugs or incomplete transcription on your part.
First, the package is called gd, not libgd, so there would be /usr/local/Cellar/gd, not /usr/local/Cellar/libgd.
Second, brew diy appears to suggest a cmake invocation, but gd uses autotools, so that is wrong.
Ultimately, this should work if you string it all together correctly, but actually, if you have problems with reaching a mirror over http, I would just put the tarball somewhere else and edit the formula file (brew edit gd) to point to that new location. Much easier, and you can even save your modification in a local Git branch.
I've recently installed MacPorts as explained on MacPorts website. All the process went well. The .profile file in my home directory has been updated (in this file the paths "/opt/local/bin" and "/opt/local/sbin" are added to the environment variable PATH) and all the macports files are in the directory "/opt". When I type "which port" in the shell, it returns "/opt/local/bin/port".
But something weird happens when I ask to install the port "octave-devel" (I've installed MacPorts to use Octave on my Mac in the first place). So when I enter the command "sudo port install octave-devel +atlas+docs" (as explained in GNU Octave wiki) in the terminal and type my password, the shell replies "Error: Port octave-devel not found". However the port "octave-devel" seems to exist because I've found its description on this page of the macports website.
Because I had to use Octave quickly I first wanted to uninstall MacPorts and install Fink instead and I tried the method described on the MacPorts website but after I typed "sudo port -fp uninstall installed" it returned "Error: No ports matched the given expression". I couldn't even uninstall this software! I really think that it is a problem of MacPorts itself and not the octave port but I can't find what exactly.
Eventually I used Octave on a Windows computer but it annoys me not to know what is wrong with MacPorts on my computer. And mainly, I want to be capable to use GNU Octave on my Mac because I need it for school.
Thank you in advance and happy holidays.
I'm not sure which version of OSX you are running, however, I have octave (not octave-devel) version 3.6.4 installed via macports on a machine running OSX 10.9.1. This was built using:
sudo port install octave
which yields a known bug building the atlas dependency that results from a missing fortran compiler. At this point you have two options. Before attempting to install octave first try to install atlas separately, either overriding the standard clang compiler with the gcc4x flag, or install atlas using:
sudo port install atlas +nofortran
which runs fine using clang. With atlas installed, octave should build to completion although there is a possibility that you will find an error regarding the use of arpack by apple as a vector library. Using +arpack is preferred, so it may be useful to load this by hand as well before starting your octave install.
Trying to install Octave using MacPorts I ran into a similar problem.
Summary
My solution was to first clean & build atlas separately using gcc47 instead of the default mpclang34. Then to build the default octave.
Details
This is on a MacBook running an older OS (10.7.5), the standard Octave (3.8.2) package failed to build - it hung on building the atlas dependency.
Solution:
sudo port clean atlas
sudo port -v install atlas +gcc48
sudo port -v install octave +atlas+docs
I'm currently going through the process of installing Octave via MacPorts. I used the following command which I found on Shifteleven.com:
sudo port install octave-devel +gcc45
It seems to be working so far. You also need to make sure you've installed the Xcode command line tools, which is something that I forgot to do the first time I tried.
I also ran into problems installing Octave using Macports on OSX 10.10.1 and solved them, similar to #Tom_N_PDX and #isak.
Short version
I got it working using one of the options described by #isak.
More detailed version
Running sudo port install octave failed because of the missing Fortran compiler problem.
I next installed Fortran using Macports sudo port install gcc48 and then tried re-installing Octave
sudo port clean octave
sudo port install octave
This "hung" on Atlas, as others have mentioned, although I now realize it just takes a long time and I killed it before it finished. Likely it would have worked, as the output said it had found Fortran
Selected C compiler: /usr/bin/clang
Selected F77 compiler: gfortran48
I then installed atlas separately, using the +gcc48 flag, as suggested by #isak
sudo port install atlas +gcc48
but it displayed the same compiler information as above (consistent with my conjecture that the above would have worked). This process took about 4 hours. You can monitor the progress of the task in the logfile (found with the command sudo port logfile atlas), which reassures you it's doing something and not "hung". (Oddly the output does halt mid-message, but it always eventually resumed. Also there were a lot of warning messages.)
Last, running the following worked:
sudo port clean octave
sudo port install +arpack
I actually first tried without the +arpack option and it worked but I got the following message, consistent with #isak's answer
WARNING: Dependency 'arpack' is installed with the +accelerate variant, using Apple's Vector Libraries which have some known bugs that can cause Octave to crash if using certain functions in arpack. The +atlas variant does not have these issues with Octave, but does take many hours to compile even on modern hardware.
When I reinstalled Octave with the +arpack flag it took less than a minute (because I had already installed Atlas).
I had a similar problem with MacPorts. I would recommend using HomeBrew instead. Here are the commands to install Octave on HomeBrew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew upgrade
brew install octave
