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 libde265 from source but one of its dependencies is giving me problems. I also installed this depedency from source but I converted it to an rpm package before completing installation.
When I look for the location of this library I get:
$ whereis libvideogfx
libvideogfx: /usr/local/lib/libvideogfx.la /usr/local/lib/libvideogfx.a /usr/local/lib/libvideogfx.so
The flags I have added to the ./configure command such as LIBS are not working and I don't know the root of the problem.
I am new to linux and i have few expect scripts to execute. I read few blogs on how to install expect and tcl. The command i am trying is
sudo yum install expect
sudo yum install tcl
I am getting
No package expect available
No package tcl available
It seems RHEL should have tcl and expect prebuilt but this is not the case in my version of linux.
How should i proceed from here ?
Help will be highly appreciated..Thanks :)
Install the development tools:
yum groupinstall "Development tools"
then
./configure
make
make install
should be good to go.
Have you tried this? In this way you will be able to compile from source.
1) Download the expect package from the below link
http://sourceforge.net/projects/expect/
2) Install the required dependecy packages "Tcl/Tk" language toolkit
# yum install tcl
3) Install the "expect" package using the below commands
# tar -zxvf expectx.xx.tar.gz
# ./configure
# make
# make install
I tried the following links and it worked for me. http://www.linuxfromscratch.org/blfs/view/svn/general/tcl.html http://www.linuxfromscratch.org/blfs/view/svn/general/expect.html
Try ActiveTcl from ActiveState:
http://downloads.activestate.com/ActiveTcl/releases/8.6.4.1/ActiveTcl8.6.4.1.299124-linux-x86_64-threaded.tar.gz
You can add EPEL Repo
On 32-Bit -
# rpm -Uvh http://epel.mirror.net.in/epel/6/i386/epel-release-6-8.noarch.rpm
On 64-Bit -
# rpm -Uvh http://epel.mirror.net.in/epel/6/x86_64/epel-release-6-8.noarch.rpm
and then you can use yum to install.
Also you can compile from source or get from ActiveState like in previous answers.
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 am trying to build a .rpm package. I have just followed the steps to do that. Till now all steps were gone fine but now i just stuck with this step. I just ran the following command and got this error:
rpmbuild -ba asterisk.spec
error: Failed build dependencies:
gtk2-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64
libsrtp-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64
[... more ...]
freetds-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64
uw-imap-devel is needed by asterisk-1.8.12.2-1.fc15.x86_64
I am using fedora-15. How to resolve this error?
How I do install all depencencies during installation of src.rpm package. Is it possible?
You can use the yum-builddep command from the yum-utils package to install all the build dependencies for a package.
The arguments can either be paths to spec files, paths to source RPMs or the names of packages which exist as source RPMs in a configured repository, for example:
yum-builddep my-package.spec
or
yum-builddep my-package.src.rpm
The same thing can be achieved on newer versions of Fedora that use dnf as their package manager by making sure that dnf-plugins-core is installed and then doing:
dnf builddep my-package.spec
or
dnf builddep my-package.src.rpm
yum-builddep doesn't seem to work if the mirror you use doesn't serve source RPMs. This may not handle all cases, but it usually works for me:
sudo yum install -y $(<rpmbuild> | fgrep 'is needed by' | awk '{print $1}')
where <rpmbuild> is your rpmbuild command (e.g., rpmbuild -ba foo.spec).
On PHP building - especially phpbrew I used dnf builddep php, it worked.
I downloaded the tar.gz from qemu.org. Now how can I compile the source code only for i386 architecture?
I mean, my qemu need not be able to emulate a Power PC, Motorola 68000 or others.
I tried the steps
./configure
make
make install
But there was a failure
No rule to build target 'all'
Apart from this, the above steps compile the qemu for all architectures too.
Hope to get some help.
On Linux Machine Download Qemu Source Code and extract in directory then cd to DIR and do following:
./configure --disable-kvm [--prefix=PFX] [--target-list="i386-softmmu x86_64-softmmu"]
make
make install
first tar it (extract it)
then go to the directory on shell
then
type this commands
./configure --target-list=i386-softmmu
when build successful
press make and enter
when this done
then write
sudo make install
that's it
For general linux,
#tar xvzf qemu-1.4.0.tar.bz2
#cd qemu-1.4.0
#./configure --target-list=i386-softmmu
#make
#make install
For puppy linux wary 530,
#tar xvzf qemu-1.4.0.tar.bz2
#cd qemu-1.4.0
#./configure --target-list=i386-softmmu
#make
#new2dir make install
#cd ..
#dir2pet qemu-1.4.0-i486
./configure --target-list=x86_64-linux-user --disable-smartcard-nss
This command work for me, while building Qemu 1.6 on centOS
