I am currently trying to install a set of ocaml packages. However, I cannot seem to find any site that allows me to download the 'pprz.xlib' package. The problem is that I would like to install that package for an ubuntu OS but I can't use the terminal to download it because I don't have internet access on the ubuntu. Therefore, I have to download it on windows, and copy and paste the package in the appropriate file in my project (it's the paparazzi code UAV for what it's worth).
Anyway, I would be greatly appreciative for anyone who may direct me to a solution on how to install such a package.
Thank you

I'm new to c development, but I have some experience in other modern languages .so the first thing that I found hard is dependencies and deployment, while we got Gradle, maven, NuGet and pipy and... but in c I find it a bit difficult to manage this process.
for example, I have an app that should use mongo-c-library, log4c,libarchive so basically, in my development environment, I download and unzip all of the tar files of the above libraries and then followed their instruction(usually some make stuff) and installed them in order to include them in code make the code work.
I have studied a bit about CMake but I couldn't get a clear picture of how that could actually solve the problem.
at this moment my best solution is to create an install bash script and zip all dependencies unzipped folder with that install script and then send it to the production server to deploy it.
1.The first question is : is it possible to just copy and past all of .so .h and etc files in /path/of/installed/dependencies/include
and /path/of/installed/dependencies/lib in the destination server libary path.
2.if not what is the faster way?
while I was surfing the CMake source file I found that its developers just use this package source code directly.
cmxxx contains the xxx sources and headers files.
3.how can apt-get and Linux package manager help in the deployment process?
2 first question was more about dependencies. imagine we have a simple c app and we want to install(build and make a useable executable file) quickly. how it can be related to .deb packages.
1.The first question is : is it possible to just copy and past all of .so .h and etc files in /path/of/installed/dependencies/include and /path/of/installed/dependencies/lib in the destination server libary path.
Yes, technically it's possible. That's essentially what package managers do under the hood. However, doing that is a colossal mistake and screams bad practices. If that's what you want then in the very least you should look into package managers to build up your own installer, which handles this sort of stuff already for you.
2.if not what is the faster way?
You're actually asking an entirely different question, which is: how should I distribute my code, and how do I expect users to use/deploy it?
If you want users to access your source code and build it locally, as you've mentioned cmake then you just to set up your project right as cmake already supports that usecase.
If instead you just want to distribute binaries for a platform then you'll need to build and package that code. Again, cmake can also help you on that one, as cmake's cpack supports generating some types of packages like DEB packages used by Debian and Ubuntu, and which are handled by apt.
3.how can apt-get and Linux package manager help in the deployment process?
apt is designed to download and install packages from a repository.
Under the hood, apt uses DEB packages, which can be installed with dpkg.
If you're targeting a system that uses apt/deb, you can build DEB packages whenever you release a version to allow people to install their software.
You can also go a step beyond and release your DEB packages in a Personal Package Archive.
You would typically NOT download and install source packages. Instead you should generally rely on the libraries and development packages of the distribution. When building your own package you would typically just reference the packages or files that your package is dependent on. Then you build your own package and you're done. Upon installation of your package, all dependencies will automatically be resolved in an appropriate order.
What exactly needs to be done is dependent on the package management system, but generally the above statements apply. Be advised, package management apparently is pretty hard, because so many 3rd party developers screw it up.
I am a beginner C programmer, and recently I have run into a problem that I was unable to solve.
I am struggling to install and use a C library. The message error is:
My OS is Mac OS X and im try install the file with ".command" format.
Can someone help me install this library?
Thanks in advance.
More than help installing the library, you need help in understanding what's going on.
Someone gave you a command to run and you ran it, but they were assuming that you were using a different OS, like Ubuntu.
The first message "apt-get not found" is because you're running MacOS, which doesn't have an "apt-get" command.
The second error is because you also don't have wget.
The rest of the messages indicate a poorly written script file, since it blew up twice and still went on to truncate files and do other things.
While you're not going to be able to install apt-get, you might be able to find a compatible version of wget. If not, you can download whatever it was trying to get using your browser, since wget is typically used to automate web HTTP/HTTPS requests.
Without seeing the file, I don't know what the rest if the script was trying to do, but if you read it you should be able to figure out what it was doing, and do it manually.
An easier way to do all this is to install Virtualbox on your mac and run a copy of Ubuntu inside a virtual machine. Then you can run your class assignments without needing to rewrite them all.
I have downloaded the 3.5 version of python on my windows 7 home premium computer with version 6.1 software. I wish to use a C main program with python library extensions. I have aded the path to the include folder and the library folder to the dev studio c-compiler. I am testing with the supplied test program that prints out the time but I get a compile error. While it can find Python.h, it can't find python35_d.lib. I can't either. Is it missing from the download or is this another name for a one of the libraries in the download? Thanks
Maybe a little too late, but I found a work around for the missing 'python3x_d.lib' : When installing the python with pythoninstaller.exe, choose the advanced setup options in the first command window of the installation wizard, there choose the option "download debug binaries", then the file python3x_d.lib is automatically installed.
I faced this error when trying to build opencv with python bindings
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
I downloaded openCV and extracted the project. I navigated into the Samples/FaceTracker folder. Double clicked on the project (FaceTracker.xcodeproj), and clicked on the run button when the project was loaded in XCOde. I get the following error, which doesn't allow me to run the application;
The run destination My Mac 64-bit is not valid for Running the scheme
'FaceTracker'.
The scheme 'FaceTracker' contains no buildables that can be built for
the SDKs supported by > the run destination My Mac 64-bit. Make sure
your targets all specify SDKs that are supported by this version of
Xcode.
The file OpenCv.framework is missing, but i looked for it and i am unable to find a file with that name. How can i resolve this issue ?
1- Your XCode project is not able to find the required library, or it finds one but its not compatible with your current operating system/processor/build settings. The missing framework and the error message suggests this.
2- May be you need to build OpenCV SDK to make sure that it's compatible with your machine, instead of trying to build the example first.
3- Instead of downloading and building openCV, I suggest you use a package management for OS X, like MacPorts. If you do not need cutting edge trunk version, this is a better option, which takes care of all the initial framework setup for you.
