we use boost1.46.1 in our c++ project. When I am building my c++ project using cmake, I am getting following errors.
I am not sure why I am getting this error. Can any one please hemp me to fix the following errors?

It looks like boost::regex sometimes depends on the ICU library. You can either link against that library, or you can follow the instructions in the link to disable ICU.
Your Boost.Regex is built with Unicode support — you need to link to ICU as well.

I am finding trouble linking a library in C++.
I am trying for the first time to use "matplotlibcpp.h". This is a library that uses "Python.h"
My code is not using either of the libraries yet. It gives error just by including "matplotlibcpp". I am using python2.7 and Ubuntu 18.04 and am using Eclipse.
The code does not run if I include:
#include "matplotlibcpp.h" // programme runs if this is commented out. But I need it to add new features.
#include "Python.h"
I have added these paths in several futile attempts (they solved similar issues to other threads):
GCC C++ Compiler, include paths (-l)
/home/toni/Programs/Workspace/Libraries/matplotlib-cpp-master/
/usr/lib/python2.7/dist-packages/numpy/core/include/numpy
/usr/include/python2.7
GCC C++ Linker, Library search path (-L)
/home/toni/Programs/Workspace/Libraries/matplotlib-cpp-master/
/usr/lib/python2.7/config-i386-linux-gnu
/usr/lib/python2.7
/usr/include/python2.7
The programme builds, but does not run:

I am trying to compile a program written in C++ using the lpsolve external library.
I have written the following line in my .cpp :
#include</var/lib/lpsolve/lp_lib.h>
However, when I'm trying to compile this using g++, I get this weird message :
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib/liblpsolve55.so when searching for -llpsolve55

collect2: error: ld returned 1 exit status
I tried many different things... Even tried to install the library manually, by downloading it from sourceforge taking care of the right version (dev-ux64 in my case) and it seems like none of the solutions I've found on the internet are working ...
By the way, I am using the following command to compile my program :
g++ prog.cpp -llpsolve55 -lcolamd -ldl -o MyExe
EDIT : after specifying the path to the librairies explicitly, i get this :

Can anyone tell me what is wrong?
If you need any more information to help answer the question just ask.
Edit (Some additional info):
As you can see from the compiler output I have linked the library that these functions require and the compiler does not complain that it could not find said library. Also I placed the freeglut dll into the binary folder.
This problem was apparently mainly due to user error and was completely circumstantial. I'm posting this for the people of the future who might have this problem.
In my header file I defined FREEGLUT_STATIC. After changing this to another variable, the linker no longer produced errors. Though I can't actually check -- very easily at least -- somewhere in my freeglut library this variable was used in an ifndef statement to determine whether freeglut needed to be linked (in case it was already linked).
I'm using robo robo simulator. It requires SDL to be installed. SDL was successfully installed using sudo apt-get install in Ubuntu
'make' was used to compile and link.
compilation was successful but while linking I got the following linker errors

Its still trying to use QT5 libraries. I have removed all the set variables from .bashrc.
How do I make the pro files look only for qt4 libs ?
