I'm trying to compile OpenCV from source and create a test C++ program which uses the newly compiled OpenCV library.
Compiling OpenCV appears to work, I followed this guide.
But now I want to create a test program which uses the library.
I followed this guide, but and everything appeared to work until I tried the command:
./DisplayImage lena.jpg
Which gave me the following error
OpenCV Error: Unspecified error (The function is not implemented.
Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you
are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then
re-run cmake or configure script) in cvNamedWindow, file

Aborted (core dumped)
the mentioned packages appear to be installed
I've tried rebooting my computer after installing the packages and I still get the same message.
Solved it
Looks like I was missing some of the packages mentioned in http://docs.opencv.org/2.4/doc/tutorials/introduction/linux_install/linux_install.html
even though libgtk and pkg-config were installed

I'm having trouble installing wxWidgets in msys2, I used pacman to install the library
pacman -S mingw-w64-clang-x86_64-wxwidgets3.0-msw
But when I try to execute a test file it gives me this error
fatal error: wx/wx.h: No such file or directory
Reading online I see that are in another methods of installing the library you have to compile it, but I can't find any information in regards to installing it with pacman.
I also tried to compile it myself with Cmake following the instructions in the wxwidgets page but I failed and I want to see what should I do now.
What I need to do to get this to work?
Using M1 Mac, I've followed the manual install procedures to install Repast HPC.
I'm trying to run ./install.sh rhpc and the following error persists:
configure: error: cannot not find the flags to link with Boost mpi
The suggested solution says to add the compiler wrappers with the following commands:
export PATH=$BASE_DIR/MPICH/bin:$PATH
MPI_COMPILER_INVOCATION=$BASE_DIR/MPICH/bin/mpicxx
which didn't work as the command mpicxx still couldn't be invoked.
So I tried installing mpich through homebrew, where mpicxx now works outside of the install. However, the error persists.
So I tried installing boost through homebrew and directing the install to the homebrew directory, but the error persists.
So I tried installing open-mpi through homebrew, and mpicxx still works, but the error persists.
Any suggestions? I'm running out of online resources to solve the issue.
I have already compiled a Script on my Desktop Computer, but now I have to compile it on a Server where I don't have root access.
So I chose to install Anaconda and work with Conda environments.
So, I'm installing a GCC 9.3 Compiler, among with a GXX 9.3 Compiler because I need the execution policies from C17++.
I also installed GSL library through conda install gsl and indeed, on conda list it appears to be:
gsl 2.4 h14c3975_4
so, I decided to compile the script via : x86_64-conda_cos6-linux-gnu-cpp SCRIPT_NAME -o _OUTNAME_ -lgsl since this is the way Anaconda says to call it's compilers (said so on build log)
but I get this error:
mpi_final.cpp:1:10: fatal error: gsl/gsl_math.h: No such file or directory
1 | #include <gsl/gsl_math.h>
| ^~~~~~~~~~~~~~~~
compilation terminated
I have managed to include GSL but ONLY when I install it manually. and then I have problem with other libraries, so I decided to fix anaconda environments. But I dont know how to proceed.
Any Idea on where to look?
I´m trying to create named windows and show an image from them using OpenCV in c++. When I try it, I will get an error saying:
The function is not implemented. Rebuild the library with Windows,
GTK+2.x or Cocoa support. If you are on Ubuntu or Debian, install
libgtk2.0-dev and pkg-config, then re-run cmake or configure script in
function 'cvNamedWindow'.
I´m on a raspberry pi using Ubuntu MATE and I didnt have this problem when I was testing on my laptop using Ubuntu. I have checked that all neccessary libraries are installed. So I run cmake again to recompile it, but it still doesn t work.
Is there something different I need to do for Ubuntu MATE? Or is there something else I should try?
I am trying to compile my own c++/qt5.2 app which uses yaml-cpp under Ubuntu 14.04.
While issuing the make command I get the following error
fatal error: yaml-cpp/yaml.h: No such file or directory
on the line:
#include <yaml-cpp/yaml.h>
How can I fix this?
You need to install the yaml-cpp library.
Under Ubuntu 14.04 you can do this by simply running one of the following commands in a terminal window (depending one the API you use):
sudo apt-get install libyaml-cpp-dev
or
sudo apt-get install libyaml-cpp0.3-dev
See the yaml-cpp project page for other operating systems and differences between old (0.3) and new API.
