I have an assignment to write a program to implement i2c communication between a temp sensor and the Adafruit FT232H Breakout board (https://learn.adafruit.com/adafruit-ft232h-breakout/overview).
The end result is this running on a Linux computer, and they did not want it implemented in python like the examples, so I decided on using the suggested C library, libmpsse,(https://code.google.com/p/libmpsse/).
after installing the libftdi library that it needs, as well as the libpmpsse code. I was able to get the .c code working, using the make provided.
There Make
LDFLAGS= -lmpsse
all: spiflash spiflashfast i2ceeprom ds1305 gpio bitbang
spiflash:
spiflashfast:
i2ceeprom :
$(CC) $(CFlags) i2ceeprom.c -o i2ceeprom $(LDFLAGS)
ds1305:
clean:
rm -f* .dsym
rm -f spiflash spiflashfast i2ceeprom ds1305 gpio bitbang
distclean: clean
What I am hoping to be able to do, is take all the required library's and wrap it all together in one package (cmake?) With the end result being single functions in a c++ file that will be able to run the functions in my .c code.
What I've tried:
Using CMake, I tried to use the add_libraycommand to tie the lmpsse.c together.
I cant post any more links but it looks like:
cmake_minimum_required(VERSION 2.8)
project(i2c)
add_library(i2cFunctions, lmpsse.c)
include_directories("${PROJECT_SOURCE_DIR}/i2cFunctions")
add_subdirectory(i2cFunctions)
add_executable(i2c i2ceeprom.c)
target_link_libraries(i2c i2cFunctions)
I then run it, with the files I want in the dir above, but it produces

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

/home/toni/Programs/Workspace/Libraries/matplotlib-cpp-master/
/usr/lib/python2.7/config-i386-linux-gnu
/usr/lib/python2.7
/usr/include/python2.7

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 trying to build a little utility program that relies upon GraphicsMagick C++ library but I got the following error when linking to the library:

Why does the library in /usr/local/lib refers to GraphicsMagick source code (that I've built and installed)?
Errors says that you need to link with libpng too.
You having very descriptive source-code related errors because you've built graphicsmagick with debugging symbols. In release build (or if you'll strip debugging symbols out of debug build) you'll see only undefined function names, without source code references of where they're being used.
I need to call some methods from a C++ program in a C program.
But I just have one shared library (.dll) to use those methods.
To make it, first a create a wrapper in C to call the methods from the dll to be used in the C program. I have attention and I make sure that I declare the functions with extern "C" to avoid name mangling.
But when a compile I have a set of errors (shown in down) when a linking wall the .o's:
