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'm getting an error while trying to connect raspberry running ubuntu mate to my Google Cloud SQL instance.
These are the step I did to install:
git clone https://github.com/GoogleCloudPlatform/cloudsql-proxy
cd cloudsql-proxy/
sudo sh download_proxy.sh
My instance is configured this way (I deleted some characters in the image and in the code):
I didn't set the network because I'll be using proxy
Then I download into the same folder my JSON key.
wget https://drive.google.com/file/d/my_key.json
And the start the proxy
sudo ./cloud_sql_proxy -instances=be - 21:us-central1:be =tcp:3306 \
-credential_file=./my_key.json &
But I'm getting the error:
pi#pi:~/cloudsql-proxy$ ./cloud_sql_proxy: 1: ./cloud_sql_proxy:
Syntax error: ")" unexpected
I've tried removing the .json and I was getting the same error before without credential, I think that the problem is in the setup.
My dir ls is:
Any help is appreciated :)
download_proxy.sh downloads the proxy compiled for the amd64 architecture of CPU (aka x86_64). Your raspberry Pi has a ARM CPU, so this binary cannot run on your machine.
Google does not provide pre-build ARM versions of the proxy. I don't even know if it is able to build on ARM CPU. If it is possible, this is how you must do it:
Install go, e.g. with apt-get install golang
Setup a GOPATH, as per https://github.com/golang/go/wiki/GOPATH
Run go get github.com/GoogleCloudPlatform/cloudsql-proxy/cmd/cloud_sql_proxy
Run the proxy with $GOPATH/cloud_sql_proxy -instances=...
Ok.
I'm sharing what I did to make it work, as David I don't know what version was I downloading.
I tried to avoid installing Go but it was the only way to get it installed.
sudo apt-get install golang-go
export GOPATH=$HOME/go
go get github.com/GoogleCloudPlatform/cloudsql-proxy/cmd/cloud_sql_proxy
cd $GOPATH/bin
wget your_key.json
sudo ./cloud_sql_proxy -instances=the_full_name_of_the_instance=tcp:3306 -credential_file=./your_key.json &
But I was getting a error because I already have mysql running localy in the same port
So now I'm using a unix soquet
sudo ./cloud_sql_proxy -instances=the_full_name_of_the_instance -credential_file=./your_key.json &
And then it's ready for connections :)
Thanks guys
I found issues with this when compiling SQL-proxy. I did, however, find the instructions here worked great on my raspberry pi 3. Have to make sure to remove all prior installations then reinstall it

Perhaps the DBD::mysql Perl module hasn't been fully installed, or perhaps the capitalisation of 'mysql' isn't right.
It looks like you're using Linux. In that case, you might find it easier to install a pre-packaged version of the module.
On a Red Hat derivative try yum install perl-DBD-mysql; on a Debian derivative try apt-get install libdbd-mysql-perl.
Perhaps the DBD::mysql perl module hasn't been fully installed
...so install it.
cpan DBD::mysql
Or since you don't have internet access,
perl Makefile.PL
make
make test
make install
You'll need MySQL's development header files installed first, as per INSTALL
any error related to DBD::mysql error has not installed fully. Please run the below code in super user permission.
apt-get install libdbd-mysql-perl
As is was not able to comment (yet), I want to add something for the Mac Users.
I hat to add the --force command to install the everything properly as i have no local mySQL installation for the tests to pass.
/usr/bin/cpanm --force DBD::mysql worked for me. (Mac OS 10.9.2, Perl 5.12.4)
I've been tried perl -MCPAN -e shell on my mac OSX 10.8.5, but this didn't work.
I tried sudo perl -MCPAN ..., but didn't work too. I changed my ~.bash_profile to include
LD_RUN_PATH=/usr/local/mysql-5.6.13-osx10.7-x86_64/lib export LD_RUN_PATH
LD_LIBRARY_PATH=/usr/local/mysql-5.6.13-osx10.7-x86_64/lib export LD_LIBRARY_PATH
lines, and I tried -MCPAN again, with and without sudo, but this didn't work too.
I read some posts and I tried "get Bundle::DBD::mysql" in -MCPAN command line to download it and install with Makefile. Then, I entered the ~./cpan/build directory and I did a Makefile, but the make command didn't work. I tried Makefile with --testuser and --testpassword that I just had been configure in mysql. I entered the site https://discussions.apple.com/thread/3932531?start=0&tstart=0&fb_source=message that is informed in README doc of ./cpan/bundle, but I already had all command line tools of xCode installed and didn't work for me too.
Why don't do sudo perl -MCPAN -e shell and to force to install Bundle::DBD::mysql? This worked well and I got the installation.
I am trying to read an image using octave 3.8. I installed octave by downloading code and making it on my system.
I used imread("oct.png")
And got this error
error: imread: invalid image file: imfinfo: support for Image IO was
disabled when Octave was built
Please help.
PS I built using the following commands:
wget ftp://ftp.gnu.org/gnu/octave/octave-3.8.0.tar.bz2
tar -xvf octave-3.8.0.tar.bz2
cd octave-3.8.0/
./configure
sudo apt-get install f2c gfortran libblas-dev liblapack-dev libpcre3-dev libreadline-dev
./configure
make
sudo make install
Thanks in advance!
First: PLease use the stable 3.8.2 tarball, not 3.8.0.
Second: I'm sure the second time you ran ./configure it told you, that the graphicsmagick libs weren't found. Have a look at config.log what's missing.
I can't see which distribution you are using. For Debian GNU/Linux (http://wiki.octave.org/Octave_for_Debian_systems) you'll have to install
libgraphicsmagick++-dev
I am trying to install Octave on Mac OS Mavericks with Brew. I ran
brew install octave --without-docs
which almost instantly gave me
Error: You must `brew link ghostscript' before octave can be installed
I did it, and it gave me the following:
Error: Could not symlink bin/dvipdf
Target /usr/local/bin/dvipdf
already exists. You may want to remove it:
rm /usr/local/bin/dvipdf
To force the link and overwrite all conflicting files:
brew link --overwrite ghostscript
To list all files that would be deleted:
brew link --overwrite --dry-run ghostscript
I ran the last, which showed me a bunch of files I have never seen before. What shall I do? Erase them with brew link --overwrite ghostscript, or do something else?
Thanks
This work for me
1.you should delete ghostscript in /usr/local/share
2.brew doctor,it will prompt you with some options
3.brew link --overwrite ghostscript
4.you can brew install octave
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
