I'm trying to compile a c programming package (thc-ipv6-0.7) on Linux Redhat 2.6.9-42.ELsmp and it's complaining that it can't find "linux/string.h".
From google, I learned that this is part of the "kernel-headers" package.
If I do "rpm -qa | grep kernel"
It shows that "kernel-devel" is installed (which I think I need), but not "kernel-headers".
A "find / -name string.h" reveals string.h is in fact on the system, in many places, including "/usr/include".
I tried adding "-I/usr/include" to the make file, but got the same error.
My question is, do I need to install "kernel-headers", and if so, where do I find it, and what version?
Normally, you have to install the version of those headers which correspond to the version of the kernel run by the system on which you'll execute the program. In your case in you want to run locally, 2.6.9-42.
The message complains about "linux/string.h" and not "string.h", so you have add a directory having linux as subdirectory.
I'm not knowledgeable enough about redhat to know how to install them (probably an rpm command) and where they will be installed (with Debian and derivatives put them you have to use -I/usr/src/linux-kernel-version/include").

So I'm in terminal, and have a directory called CAPTURE on my desktop, I'm trying to run a program called 'testme'. I read that you need to have build-essential installed but I think that's only on Linux systems and I'm on a Mac so it wasn't necessary because it's already built in (I think). So, I navigated from ~ with:
cd Desktop/CAPTURE
Then, I tried running a bunch of different commands that I found while looking on the internet:
./testme
which returned zsh: exec format error: ./testme
xcode-select --install
which installed properly and I thought I could run the ./testme command but I got the same error as before. Then I tried navigating to the directory again and used
chmod +x ./testme
./testme
which also did not work. I've never run executables before so I really have no familiarity with these commands so they might be super wrong. If anyone can help me run the file properly, that would be much appreciated.
Since your question is tagged as C and Clang, and you are talking about build-essential, I will assume that you are attempting to build an application from source code.
Instead of build-essential, in macOS, you need Xcode. The Xcode CLI tools will work if the application is text-only or Curses, but you will need the entire Xcode IDE for any graphical application.
If running ./testme is telling you Executable format error is probably because it's a prebuilt executable, very likely a Linux ELF executable that will not run in macOS.
My suggestion is to try to build the software. Most C applications will build if you run make inside the directory. make is installed by default by Xcode. Other applications may need a third-party build system, such as CMake, but I do not know if that's the case.
I am new to fedora (Linux). Just installed glib packages using yum install glib*. But still not able to compile.
I used locate to find where the pkg-config file is. I opened all of these but could not find PKG_CONFIG_PATH environment variable. Any help? :)
pkg-config files are stored in /usr/lib64/pkgconfig/* or /usr/lib/pkgconfig/* (depending on whether you're on 64-bit or 32-bit).
The glib package contains glib 1.x, for glib 2.x the right package is glib2 (backwards-incompatible API changes require a new package).
Furthermore, development headers, documentation, pkg-config files, etc., are provided in a separate package, which is usually called '$packagename-devel'. This split allows you avoid installing all the development stuff if all you want to do is use the library. So, what you really want is yum install glib2-devel.
Note that, since you know the pkg-config name, you can just do yum provides '*/glib-2.0.pc' (or provide the full path and you'll only get a single result) to find the packages which provide the glib-2.0 pkg-config file. With dnf you can also just do something like dnf install '/usr/lib64/pkgconfig/glib-2.0.pc', not sure if the version of yum from F16 can do the same or not, which brings me to…
Fedora 16 is way too old. Unless you have a very good reason for using this specific version of Fedora, stop doing so. Beyond being a much less pleasant experience, Fedora 16 is old enough that it is no longer receiving security updates. If you need to use something from that era you should find something that is still supported (RHEL 6 is based of F12, RHEL 7 is based on F19, you can use CentOS if you don't want to pay for support).
I have downloaded and ran the CUDA 5.0 installer on my Mint 15 64bit distro. After hours of agony adjusting / removing / installing packages, it was able to finish installation - at least that what it said.
I can go run the CUDA samples so I thought hey it's working. However, I just made a new cu file and wanted to compile but it said "nvcc command not found"
I have looked at a topic similar to this here and they are talking about /opt/bin/ directory however on mine, there is no such directory. Does that mean it actually did not install ? It tells me to install nvidia cuda toolkit with apt-get but I am not sure if I should do that.
Also, I did say I ran the CUDA samples fine but I have to say ldconfig /usr/local/cuda/lib64
before I can get it to working. Is there a way to automate that ?
Thanks
You need to add the bin directory of the nvcc compiler driver to your PATH (environment variable), and you need to add the appropriate lib directories to your LD_LIBRARY_PATH environment variable.
For an immediate test, this should be as simple as:
export PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/lib
These instructions should be presented to you at the completion of a successful cuda toolkit install, but it seems your install method may have been roundabout.
To make this "automatic" you may want to investigate one of the methods to add these statements to a script run at login. For example, if you have a .bashrc file in your user's home directory, try editing that with the above commands. It should probably be sufficient to put the above commands at the very end of your ~/.bashrc file if you have one.
Note that Linux Mint is not one of the officially supported CUDA distros, so your mileage may vary.
I am a begineer trying to get code in C. I am working on a Mac and using xcode. My only past experience has been with java using eclipse and everything was pretty straight forward. I have almost no experience with terminal.
I am required to learn a bit of C for a project I will be working on and the learning of syntax is coming along okay, but I am at a point where I need to include some libraries in my c program. Specifically I am attempting to make plots with gnuplots.
I have downloaded gnuplot-4.6.3 from their repository and I do not even know how to install the files. I have been looking around and have tried using terminal to use the ./configure command when I am in the gnuplot-4.6.3 directory. But I really don't know what I am doing so I don't even know where to go next or what to do next.
Sorry if this is so trivial, I honestly just have never done this before and I cannot find a good tutorial on what to do.
Thanks for any help you can offer.
I would recommend using MacPorts for installing third-party tools and libraries. It knows the dependencies required and will install them as part of the installation.
Download it from macports.org.
Install it, and allow it to modify your ~/.profile so that /opt/local/bin is in your $PATH (any issue then just do export PATH=/opt/local/bin:$PATH from the command line).
sudo port selfupdate
sudo port install gnuplot
Now that will install the library into /opt/local/lib with the include files in /opt/local/include, so now just add that library to your Xcode project. Select the target and in the Build Phases tab open up the Link Binary With Libraries and press the + button and select Add Other. Now find /opt/local/lib/libgnuplot.a (I am assuming that's what it's called; I don't have it installed my self):
Now add /opt/local/include to your Header Search Paths so the compiler can find the gnuplot header files. Select the target and in Build Setting type in "header search" in the search box. Now double-click on the Header Search Path in the target column (or the project column to the right) and add /opt/local/include:
It's fine! You're learning then! Keep up! When I hit this kind of problem you may want to learn about the basis for linux gcc/g++ compilation and linking processes. Then you should learn Cmake and Automake, which are basically packages to configure projects before compiling building.
A typical (good) project in Unix systems build with commands
./configure
make
sudo make install
or
cmake CMakelists.txt
make all
sudo make install
That's what you need to do after downloading a source tarball online to install unix programs.
Now since you are using Mac, there are so-called package installers, one which is macports and homebrew. I personally suggest homebrew than macports here (I've tried both, although macports still outnumber homebrew with the number of repos, homebrew has the newest support, especially when upgrading to a new OS). So to install homebrew you can do
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Execute that in your terminal (see http://brew.sh/) for more information.
Then you could simply install GNUplot by
brew install gnuplot
How do I use Python to check if the Gnome running is Gnome 2 or Gnome 3 ?
Use python to run a command such as "gnome-about –gnome-version" in the operating system shell.
This bypasses distribution and indeed operating system package management nightmares as as long as gnome is installed in path it will respond correctly. No messy uses of apt/yum/pkg_*.
Look at python's Operating System module, specifically the os.system() command. http://docs.python.org/library/os.html#os.system . There are more elegant ways I'm sure, but this'll solve your issue.
Of-course this will only work if gnome is actually installed. I assumed it was given that you were asking what version it was. Lubuntu is a remix of standard ubuntu, and does not come with the full gnome desktop installed by default.
The following command will show installed packages that have gnome in the name.
dpkg -l | grep gnome
To find the exact name of the gnome-desktop package you'd do something like the following:
apt-cache search gnome desktop
And then the following to install a specific package.
sudo apt-get install <package_name_here>
Both gnome 2 and gnome 3 use information from a certain file to display gnome version in System Info. The file in question is called gnome-version.xml
In gnome 3 it is part of the package gnome-desktop so it shouldn't be missing from any gnome 3 install regardless the distro. The difference is that in gnome 2 it's either installed in
/usr/share/gnome-about/gnome-version.xml
or missing, while in gnome 3 it's always located here:
/usr/share/gnome/gnome-version.xml
So I guess it's only a matter of checking for the right file in the right location.
