Ubuntu :: Code Library Required By VISA Not Located / Loaded
Mar 31, 2010
I need to create a test setup in my lab that will run power supplies for an indefinite amount of time. It could be anywhere from days to months at a time. This rules out matlab, as its memory leaks won't let it run that long, and LabView is too buggy (at least in my experience. and it has memory leaks as well). So I need a way to program GPIB (since that is the interface these power supplies have). So far, PyVISA seems to be the most likely way to be able to do this.
However, I keep receiving the following error:
Code:
pyvisa.visa_exceptions.VisaIOError: VI_ERROR_LIBRARY_NFOUND: A code library required by VISA could not be located or loaded.
Searching around, this apparently means that I'm missing GPIB drivers, but I'm not.
linux-gpib installed, and the card appears in /dev.
That being said, every now and then the gpib interfaces simply disappear from /dev,and the only way I can get them back is to reinstall linux-gpib. Also, has anybody else succeeded in working with GPIB outside of LabView and Matlab, and if so how? I'm also open to other options, having made no progress on this after over a week. The two real requirements is that I need programming interface to be scpi commands, and I would prefer to code in python or C/C++.

How can I see if a shared library is currently loaded? (i.e. system-wide, process agnostic)How can I see all shared libraries loaded by a process?

This is the error I receive when I try to install a library. I really do not know If I could do something to skip this error message.
As you might see below. I receive the following error message
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared library '/home/apa/R/x86_64-unknown-linux-gnu-library/2.11/RandomFields/libs/RandomFields.so':
/usr/lib64/R/lib/libRlapack.so: undefined symbol: _gfortran_concat_string

Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.
There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.
Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.

I am trying desperatly to install boxee onto my pc Boxee - Watch Movies, TV Shows and clips from the Internet on your TV.without success.I have downloaded the source code from the site and have ran
./bootstrap
./configure
The ./configure last few lines =
checking for boost/shared_ptr.hpp... yes
checking for main in -lGL... no
configure: error: Could not find a required library. Please see the README for your platform.
I'm not sure what this lGL is referring to. The readme states that I need the below to run the configure, though that doesn't say lGL either?
Build-Depends: debhelper (>= 7.0.50), quilt, python-support, cmake,
autotools-dev, autoconf, automake, unzip, libboost-dev,
libgl1-mesa-dev | libgl-dev, libglu-dev, libglew-dev, libmad0-dev, libjpeg-dev,
libsamplerate-dev, libogg-dev, libvorbis-dev, libfreetype6-dev,
libfontconfig-dev, libbz2-dev, libfribidi-dev, libsqlite3-dev,

is there a way to specify that I need a 32bit version of a certain library on the "Requires" line of a SPEC file?Since my software contain (a lot of) binaries from other sources (not always RPM compatible) I had to do "AutoReqProv: No" so I can do it manually.Is there a way to explicid say that I need the 32bit version of some library?

i try to compile a c code which uses SSH library,but i get this error
Code:
libssh.h: No such file or directory
i searched and i found that This happens if a library used for linking is not present in the standard library directories used by gcc.
By default, gcc searches the following directories for header files:
/usr/local/include/
/usr/include/
and the following directories for libraries:
/usr/local/lib/
/usr/lib/
i update my libssh from libssh-0.4.2-1.fc13.i686 to libssh-0.4.6-1.fc13.i686, and there are files called libssh.so.4 and libssh.so.4.0.2 in /ur/lib, but i still can't compile it with this command:
gcc test.c

Now I want to include the lzo library in the source code of linux.According to the instructions given in the package, I have copied the files (minilzo.c,minilzo.h,lzoconf.h,lzodefs.h)in the source directory(/mm),added minilzo.o to my Makefile and have included(#include minilzo.h) from my program. But when I compile the kernel,I am getting errors.

I have a question about choice of library to be used on low-end systems. I've so far been using SDL to create a user interface for a media system, and it's been working fantastically on my development machine, a dual core 2GHz machine with 2Gb RAM and an Intel graphics card. I get a frame rate of up to 100fps, and there is no slowdown at all. However when I run the exact same program on an embedded motherboard, the VIA EPIA EN15000G, which has a 1.5GHz processor, and a VIA P4M800 graphics chip (possibly the worst graphics chip ever invented as far as Linux support goes), I get a frame rate of less than 5fps. This makes the entire program totally unusable, and I've been left in a bit of a pickle. I've looked into alternatives like SFML, but that looks like it won't help at all on an unaccelerated system. I've also tried using OpenChrome drivers on it, and that made a negligible or nonexistent difference.
Can anybody suggest anything I could look into re: optimising my code or changing libraries goes? I already use SDL_DisplayFormatAlpha to convert my surfaces to the correct format. I haven't looked into Dirty Rectangles yet massively, as there's not much movement at all on the GUI, just the changing of button states.
Would use of OpenGL help at all if using the OpenChrome driver, which apparently has 2D acceleration? I'm more than willing to totally overhaul the code if needs be.

I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.

How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.
