I've got a very small and simple github project which I would like to integrate with travis-ci.org (.travis.yml file). Unfortunately, compilation fails (travis console log), the compiler cannot find cppunit even though I run sudo apt-get ... to install it.
The test/list_test.h file has got the following line:
#include <cppunit/TestFixture.h>
As I said, travis compiler cannot find cppunit headers. Can anyone point me out what am I doing wrong?
CMake was OK. Travis Script was also OK. But the cppunit package was mistaken. It should be libcppunit-dev instead of libcppunit-1.12-1

I am trying to compile dlib 19.4 using the vcpkg tool
since I am having trouble compiling CMAKE and working with Boost.Python
to fix compiler issues for dlib.
Though I am having problems even running the basic steps
to get the vcpkg package to work:
(I also downloaded Visual Studio 2017 for this tool)
Looking at executed command (git init), you initialized empty git repository for vcpkg - that is likely wrong. This bootstrap.ps1 script fails internally when trying to fetch existing revisions. vcpkg doesn't want to reside in just any git repository, it wants "its" git repository. vcpkg uses git as a distribution platform and later to perform updates.
So instead, you should clone vcpkg repository to some directory, e.g.:
C:\test>git clone https://github.com/Microsoft/vcpkg.git vcpkg_test
Cloning into 'vcpkg_test'...
...
Checking out files: 100% (876/876), done.
C:\test>cd vcpkg_test
C:\test\vcpkg_test>powershell -exec bypass scripts\bootstrap.ps1
https://github.com/Microsoft/vcpkg/
Additionally I see errors regarding VS2017 C++ support. VS2017 is an IDE with multiple optionally supported languages (i.e. you could have only C# support installed). Please make sure you have "Desktop development with C++" workload installed - as vcpkg is for C++. You can update the installation at any time by running installer again (Modify).

Firstly, I know nothing about C/C++, but I am trying to compile LCI https://github.com/justinmeza/lci under Windows 10 with Visual Studio 2015, but I'm getting the following error:
Cannot open include file: 'getopt.h': No such file or directory.
I see that getopt is not part of Visual C so people are saying you have to implement your own. It looks like this is what I need:
https://github.com/skandhurkat/Getopt-for-Visual-Studio/blob/master/getopt.h
Problem is, I don't really know what to do with this file. I've been reading a fair bit and messing around for ages just to compile lci.exe!
Already emailed the OP about this, but here's the steps I followed in order to build lci successfully. The missing step seemed to be that Justin Meza neglected to mention that you need to install CMake as well in order for the install script to work. CMake will allow you to build C code against the glibc headers.
Install MinGW
Install Python 3.5.1 (or latest Windows version)
Install Git for Windows (if you haven't already)
Make sure to enable Git for the Windows command prompt
Install CMake
Add MinGW and Python to your PATH environment variable. I'd double check that your paths to the executables are correct, mine looked like this:
C:\Program Files\mingw-w64\mingw64\bin
C:\Users{username}\AppData\Local\Programs\Python\Python35-32
Run a command prompt as administrator, and go to your Documents folder and clone the lci repository (if you haven't already):
git clone https://github.com/justinmeza/lci.git
Go into the lci directory, and run:
install.py --prefix="C:/Program Files/lci"
Add lci to you PATH, if using the default location add this to the end of your PATH:
C:\Program Files\lci\bin
I would have included some links to the various programs above in steps 1-4 but apparently I don't have enough reputation on StackOverflow for that...you should be able to find them easily enough in a quick Google search.
You should now be able to run lci from any command prompt. A good test would be to run the "HAI WORLD" code at lolcode.org.
Just copy getopt.h to the directory where .c files are, so the compiler can find it.
Based on the linked source code and it's contents, the project you're trying to build appears to be written for Linux. It might be possible to sufficiently rewrite it to be able to compile under Microsoft Windows, and Microsoft's compiler; or perhaps install something like MinGW.
However, given your stated lack of development experience, this does not appear to be something that you could easily handle on your own.
I'm using minGW with NetBeans to programming in C++. I know that I should use VS but it's defined to use NB.
Now I need to make unit tests. I tried to use cppUnit but I just can´t install it correctly. I tried to follow several tutorials and nothing.
From commands errors to NetBeans errors.
I have minGW installed with Msys.
I tried to use cppUnit but I just can´t install it correctly.
You can't install CppUnit out of the box, you have to build it before.
Steps to do
Get the sourcecode
Build it
Install (depends on how you handle your probjects)
Add to your project
Get the sourcecode
You can get the sources from the CppUnit website at freedesktop.org.
Either clone the git repository or download the release version.
Build it
The build is done using configure and make:
cd cppunit
./autogen.sh
./configure
make
make install
Do not use the windows cmd for that, this may fail - use sh instead (eg. open a cmd and execute sh to get a mingw shell).
Install
For installation on windows see INSTALL-WIN32.txt file within cppunit.
Add to your project
You have to add the compiled binaries to the linker- and header paths to compiler flags. This strongly depends on how you build your project (= the one with your unit tests).
Since your question is tagged with netbeans, there's something realy cool:
You can add cppunit only as testing dependency. For a default NetBeans C/C++ this is done through a right click on "Test Files" -> Properties" -> "C(++) Compiler respectively Linker settings.
Unit tests can be added manually or through the "New File" Dialog.
I'm using Fedora 17 and compiling cocos2d-x. I've got an error at the compilation when I'm launching ./make-all-linux-project.sh.
G++ tells me that GL/glfw.h does not exist and then I yum install glew but it wasn't solved. So how can I solve this?
The package glew is actually the OpenGL Extension Wrangler. In this case your error is referring to a different package - GLFW. The problem with the build script you are trying to run is that it was made for deb-based systems, not rpm-based systems like Fedora. What's going to make this more difficult is that if you use YUM to download glfw and glfw-devel, they are not the version Cocos2d-x needs, so the build will fail. What you will need to do is first download a legacy version of glfw from Git Hub and build it from source.
git clone https://github.com/glfw/glfw-legacy.git
Once you build this package, you will need to modify the Cocos2d-x make file: $COCOS_ROOT/cocos2dx/proj.linux/cocos2dx.mk to include the legacy headers and also link to the legacy lib. The build should go smoothly after this, assuming all of your other dependencies are installed. You can refer to a blog post I put together for the detailed instructions: http://voidfuture.wordpress.com/2013/10/08/building-cocos2d-x-on-rhel-fedora-centos-linux/
I am using Rstudio to create a package, and exploring the use of the Rcpp package to gain access to C++ code, however, when trying to build the package, and error is being thrown as follows:
fatal error: Rcpp.h: No such file or directory
Inline C++ code compiles fine, its only when considering standalone C++ files in the src folder, obviously referring to the #include <Rcpp.h> directive at the head of the .cpp file.
I think it may have something to do with environment variables, does anyone know what the correct configuration is and how to fix for Rstudio operating in an Ubuntu 12.04 LTS environment?
The commands sourceCpp('./src/xyz.cpp') execute as to be expected, the error is being thrown when Build and Reload is executed from within the RStudio IDE.
It is hard to say without having the package available. I guess you miss:
LinkingTo: Rcpp
in your DESCRIPTION file.
Did you by chance start with 'Create a package' in RStudio? If so, are you aware that you may have missed its sibbling option 'Create a package w/ Rcpp' ?
See the page on Using Rcpp with RStudio site for details, and particularly the final section on package building.
Also note that we wrote an entire vignette on using Rcpp with your own packages so I suggest you have a look at that too.
I encountered this same symptom (Rcpp.h: No such file or directory) when trying to install the "xml2" package on an Ubuntu 14 system. In my case the root cause appeared to be a bad installation of package "Rcpp". Some of the files were there (Rcpp/libs) but others were not (Rcpp/include). I am not sure how the system got into this state but I suspect an installation of that package terminated part way through. Re-installing package "Rcpp" cleared up the issue for me.
This is because your GCC has been updated, and it is different than the one you had when you installed R. I had the same problem.
I removed the package "Rccp" by using:
remove.packages("Rcpp")
Then you need to install it again. Just run:
source("https://bioconductor.org/biocLite.R")
biocLite("Rcpp")
