How to run a object TCL script in a LINUX environment? I am working with tcl 8.4. When i am trying to run a below code,
package require Itcl
class Tree {
variable parent ""
}
I am getting error "package undefined".
Is it possible to run a object TCl with out a package?
How to check whether the package is installed are not?
can any one help me. Any comments are accepted.
You need to install the Itcl package onto your system. As you don't say what variety of linux this is we shall guess that it is debian based. apt-cache search itcl shows itcl3 and itcl3-dev so it is likely that installing these packages will make this available.
On Debian based systems dpkg --list packagename shows if it is installed or not. For instance on my Ubuntu system:
$ dpkg --list tcl
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description

ii tcl 8.5.0-2 The Tool Command Language (default version) - run-time files
If you are using some other Linux variety you may need to find the package management utilities for that system or get the sources for Itcl and build it yourself.

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.
For the debugging purpose, I want to invoke the GTK failed dialog.
In Ubuntu, I can find the binary at /usb/lib/gnome-session/gnome-session-failed. Is the same function executable available in Fedora? I tried to search around but could not find it in the system.
Fedora version: 18 (Spherical Cow)
GNOME version: 3.6
You can check files in a rpm package this way:
$ rpm -ql gnome-session | grep failed
/usr/lib/systemd/user/gnome-session-failed.service
/usr/lib/systemd/user/gnome-session-failed.target
/usr/libexec/gnome-session-failed
Seems for the version you are using there was not such executable and the fail dialog would run by doing : gnome-session whale.
See: https://github.com/GNOME/gnome-session/blob/e59b938c644a78236fd5ed9d708022be3b990ddc/gnome-session/main.c#L296
gnome-session-failed is not available in the version you mentioned.
you need to use gnome-session instead and specify with -whale.
I need to add new functionality to a chinese Linux-based time attendance clock. More specifically I need to make It SNMP capable, which is not available by factory default.
After some research I found a login:password which worked for the TelNet login and managed to get inside the system with root privileges.
The first thing I did was to figure out which Linux distro was It running:
cat /etc/issue throws this:
"PXA Linux Preview Kit
Kernel 2.6.29 on armv5tejl"
I did a quick google search and found that
"PXA Linux is a port of the Linux kernel for PXA based processor based devices and machines."
I dont understand why It's running a PXA Linux Preview Kit on an armv5tejl.
I gave no importance to this fact, and got to the next step: finding which package manager has this system:
I tried several commands:
apt-get, aptitude, rpm, dpkg, yum, slapt-get, ipkg, and several others. None of them worked.
I found that the system had Busybox installed. More specifically BusyBox 1.15.3. In this BusyBox I couldnt find any of those commands. I found that BusyBox does implement rpm and dpkg but this version doesnt have them.
The only command which seems to be "software installation related" I found was the command "install". From BusyBox docs:
"install [-cdDsp] [-o USER] [-g GRP] [-m MODE] [source] dest|directory
Copy files and set attributes"
But probably it doesnt replace the package manager tool. I think that I need to get a way to install dpkg or rpm, and then use them to install the SNMP packages I want. As I read, the lowest level package installation tool is dpkg so I don't have a clue on where to begin.
Can someone give me some advice on how to approach this issue? How can I install a package with no package manager possiblities at all?
You won't be able to install additional software to that system via a package manager. Such devices aren't designed like that. The firmware that was shipped with the device is all there is. What would be the incentive of the device manufacturer to maintain a package repository with general purpose linux software?
But not all hope is lost. You can of course try to compile the needed software yourself (and by that extend the firmware). For that to work you will need a suitable ARM cross compiler (GCC). Via static linking your SNMP package won't have any dependencies to the library versions already on the device (so you don't need a sysroot matching the libraries on the device).
The release notes for RedHawk 2.0 say that the GPP device previously written in Python has been replaced with one written in "Written in C++, so it is more responsive". But I find it still running in Python (according to ps command python is running GPP.py, and the $SDRROOT/dev/devices/GPP/GPP.spd.xml which also has softpkg version="1.10.0". Was my installation defective and I still have parts of the 1.10 runtime system? My IDE says 2.0.
It sounds like REDHAWK 2.0 was not properly installed on your system, the IDE and the framework/assets are separate and it is possible to get into a situation with conflicting versions depending on the installation steps taken.
Determining what version of REDHAWK you have installed can be determined in a handful of ways. If you installed via yum or rpm you can check the versions of the rpms installed with:
rpm -qa | grep -i redhawk
The redhawk package, and redhawk-ide package should both be at 2.0. Note that the REDHAWK assets are versioned independently.
If you installed via source, you can use the package config files to obtain version information. The framework keeps it's pc files in $OSSIEHOME/lib64/pkgconfig:
cat $OSSIEHOME/lib64/pkgconfig/ossie.pc
Will print out version information for the core framework installed. Depending on what is installed, there are pc files for the framework, bulkio, frontend, and burstio.
I am sorry. The GPP-2.0.0-3.el6.x86_64 DOES contain an ELF executable for GPP device. But the rpm does not install unless I manually erase the GPP-1.10 pkg. Until erased yum says "nothing to do" for some reason. I saw the source code in GPP-debuginfo but did not notice the executable in GPP-2.0.0 since it was all caps and looked like the directory.
I'm trying to install plone 4.3.4 on a SLES 11 SP3 64bit server via the Unified Installer. I've fullfilled all the dependencies listed in the readme.txt, but when I try to get the installer running with the command sudo ./install.sh --password=******* standalone I get the error message: which: no python2.7 in (/usr/bin:/bin:/usr/sbin:/sbin) Unable to find python2.7 on system exec path.
I find that rather strange as in the description of the unified installer it is said "The new Zope/Plone install will use its own copy of Python, and the Python installed by the Unified Installer will not replace your system's copy of Python. You may optionally use your system (or some other) Python, and the Unified Installer will use it without modifying it or your site libraries." on the Plone-Website.
So - what am I doing wrong???
I've just tried adding the parameter --build-python but had to find out that the libxml2-devel and libxslt-devel libraries that are available for SLES-11-SP-3 are sadly not up-to-date enough 2.7.6 instead of 2.7.8 and 1.1.24 instead of 1.1.26 respectively. So no joy there either. :-(
Is there any way to install the current version of plone on SLES 11 SP3 64bit?
Kate
The installer command:
./install.sh standalone --build-python --static-lxml=yes
worked perfectly for me. The installer downloaded and built the Python and libxml2/libxslt components necessary to remedy the terribly out-of-date (and vulnerable) versions included with sles11sp3.
System packages needed for the build were:
gcc-c++
make
readline-devel
libjpeg-devel
zlib-devel
patch
libopenssl-devel
libexpat-devel
man
All installed via zypper.
I'd advise not using sudo for the install. If you want to, you'll need to create the plone_daemon and plone_buildout users and the plone_group group in advance due to oddities in SUSE's adduser implementation.
