I wrote a simple program using boost filesystem library. I linked to libboost_filesystem but yet I get undefined reference linkage error.
Here is my CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(client)
add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} --std=c++11")
add_executable(client main.cpp UploadWorker.cpp FileSystemWatcher.cpp)
target_link_libraries(client boost_filesystem boost_system pthread)
I tried all of the solutions in other topics, but none of them was helpful.
and here is my error:

This is the program I want to run, main.cpp:

Looking at the output, there is the following line:
c++: error: yaracpp/main.cpp: No such file or directory
Does the file exist? Looking at your CMakeLists.txt, the file appears in the following command:
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} [..] yaracpp/main.cpp ")
^^^^^^^^^^^^^^^^
Why do you add yaracpp/main.cpp into CMAKE_CXX_FLAGS when it (apparently) has already been added in the following line?
add_executable(main main.cpp)
^^^^^^^^
I highly suggest learning the basics of CMake before continuing in your endeavors.

You're using language/locale-specific double quotes. Most programming languages don't support these, including CMake. Use the "normal" double quotes: "
I try to set up an SDL project using CMake, but it seems like the executable isn't linked properly.
This is the CMakeLists.txt I use
cmake_minimum_required(VERSION 3.0)

set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake/modules)
# find SDL2
find_package(SDL2 REQUIRED)
include_directories(${SDL2_INCLUDE_DIR})
set(SOURCE_FILES src/main.cpp)
add_executable(MuspellsheimR ${SOURCE_FILES})
target_link_libraries(MuspellsheimR ${SDL_LIBRARY})
src/main.cpp looks like this:
#include <iostream>
#include <SDL.h>
int main(int, char**){
if (SDL_Init(SDL_INIT_VIDEO) != 0){
std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
return 1;
}
SDL_Quit();
return 0;
}

The functions in standard blas libraries are
dgemv_
Instead of
dgemv
As shown in your error, notice the trailing underscore.
So you probably have something in your code calling dgemv() instead of dgemv_(), change that and then you should be fine.
(I had the same issue where the code I was using had some like #define dgemv_ dgemv)
