I'm trying to link soplex (the infinite precision LP solver of SCIP) in my C/C++ code. I managed to install soplex in my linux machine and from the command line it works.
My problem is that I do not manage to link it in my code:
I'm currently using a normal makefile in which I've put:
#sopleX HERE
SOPLEX_DIR = /home/fabio/Dropbox/WORKING/SETUP_BPP_CODE/soplex-5.0.1/buid/lib

DBG= -O3 -DIL_STD
INCDIR = -I. -I$(LP_INCLUDE) -I/usr/local/include -I$(GRB_LP_INCLUDE) -I$(SOPLEX_INCLUDE)
CXXFLAGS = $(DBG) $(INCDIR)
.c.o:
gcc -c $(CXXFLAGS) $< -o $#
#LDLIBS = $(CONCORDE_LIBS) $(MY_LIBS) $(LP_LIBS)
#LDLIBS = $(CONCORDE_LIBS) $(LP_LIBS)
LDLIBS = $(LP_LIBS)
all:BPPS
BPPS: $(OBJS)
$(CXX) $(CXXFLAGS) -o $# $(OBJS) $(LDLIBS)
$(OBJS): Makefile
clean:
rm -f $(OBJS) rm BPPS
but when I try to compile it gives me a series of errors:

I think that there must be a problem linking the libraries of gmp, can anybody please help me?
The library gmp is here:

INTERFACE_LINK_LIBRARIES "/usr/lib/x86_64-linux-gnu/libz.so;/usr/lib/x86_64-linux-gnu/libgmp.so;/usr/lib/x86_64-linux-gnu/libgmpxx.so;quadmath"

I've built soplex from source, dowloaded from the scip webpage
Do you have an example of makefile in which soplex is linked?
MANY THANKS!!!!

I built gRPC from source with cmake.
I then build my client which is gRPC based with cmake.
As far as I understand the linking error I get is not related to my source code but perhaps a configuration issue. The weirder thing is that the libraries the linker complains about should be a part of the libgrpc++.a(based on gRPC cmake.)

For those who may run into the same issue, there is a conversation about this at https://github.com/grpc/grpc/issues/31449.
I compiled source code and make .o files, but linker still returns mistakes below.
There is undefined reference to constructor UaMutexLocker and others as you can see below. I added path to library -luabasecppd where is this contained, but I don't have any idea, why it doesn't work.

From what I can tell, some necessary parts of the libpq library can't be found. I don't know if I'm supposed to be using -I or -L, /usr/lib/postgresql/13/ or /usr/include/postgresql or something else, so I've just been trying different combinations, but to no avail. In addition to installing PostgreSQL, I installed libpq-dev with apt-get, but I don't know what that actually did.
I have downloaded and installed this C++ package for plotting and visulisation https://github.com/alandefreitas/matplotplusplus. I have sussessfully linked to it in my CMake file and have no linking errors when including #include <matplot/matplot.h>. However, whenever I use any functions from the library matplot.h I get the following error at compilation.

The errors are plenty, but they are all of the form undefined reference to png_... or undefined reference to jpeg_... except for those that are undefined reference to 'uncompress'. It seems as though CMake is not finding png and jpeg. I definitely do have libjpeg and libpng installed. Why are these errors ocurring? Do I need to add lines to my CMakeLists.txt to find jpeg and png? I am running Ubuntu 20.04, g++ 9.3.0, and cmake 3.16.3.
Here is a very simple example that prodces the error. This is the cmake file
cmake_minimum_required(VERSION 3.10)
project(example)
set(CMAKE_CXX_COMPILER "c++")
find_package(Matplot++)
add_executable(example example.cpp)
target_link_libraries(example PUBLIC matplot)
Here is an example c++ code (pulled directly from the examples on the linked site).
#include <cmath>
#include <matplot/matplot.h>
int main() {
using namespace matplot;
std::vector<double> x = linspace(0, 10, 150);
std::vector<double> y = transform(x, [](auto x) { return cos(5 * x); });
plot(x, y)->color({0, 0.7, 0.9});
title("2-D Line Plot");
xlabel("x");
ylabel("cos(5x)");
show();
return 0;
}
I had the same problem (with Windows MinGW). Thanks to #drescherjm hint (add the option -DBUILD_SHARED_LIBS=ON), these are the steps I used to solve the problem:
git clone http://github.com/alandefreitas/matplotplusplus
cd matplotplusplus/
mkdir compil-release && cd compil-release
rm CMakeCache.txt # if already exists
cmake .. -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX="${YOUR_LIB_PATH}/matplot1.0.1"
make -j4 && make install
Then, and I guess that is a bug, I had to manually copy the .dll to the install path
cp source/matplot/libmatplot.dll ${YOUR_LIB_PATH}/matplot1.0.1/lib/
Hope this works for you.
I've just started to learn openGL programming with the openGL Superbible. Unfortunately I'm not able compile any example. I'm on Ubuntu 18.10 and I prepared the development environment with these packages from the official repository:
mesa-common-dev (with these package you get header files in /usr/include/GL/)
libglfw3-dev (header files in /usr/include/GLFW/)
The book uses a small framework with an entry point in the sb7.h header (in the book source code), sb7.h then points to glfw3 and gl3w (the latter given with the book's source code, so you don't need to download it).
This is the first example from the book:
#ifndef _LINUX
#define _LINUX
#endif
// Include the "sb7.h" header file
#include "sb7.h"
// Derive my_application from sb7::application
class my_application : public sb7::application
{
public:
// Our rendering function
void render(double currentTime)
{
// Simply clear the window with red
static const GLfloat red[] = { 1.0f, 0.0f, 0.0f, 1.0f };
glClearBufferfv(GL_COLOR, 0, red);
}
};
// Our one and only instance of DECLARE_MAIN
DECLARE_MAIN(my_application);
If I try to compile it (the file is called 'main.cpp') with g++ main.cpp -lglfw I get this error:

Reading the messages I thought that something was wrong with the gl3w library, so I downloaded it from the github repository and I put it and glcorearb.h in /usr/include/GL/, pointing the #include in sb7.h to that folder.

g++ -c gl3w.c
g++ -c main.cpp
g++ gl3w.o main.o

At this point I tried with the single file version of gl3w.h which already includes gl3w.c. I put the two headers in /usr/include/GL/ and then I pointed sb7.h to that version of the library, but other errors appeared with g++ main.cpp -lglfw:
In file included from main.cpp:6:
sb7.h: In member function ‘virtual void sb7::application::run(sb7::application*)’:
sb7.h:137:9: error: ‘gl3wInit’ was not declared in this scope
gl3wInit();
^~~~~~~~
sb7.h:137:9: note: suggested alternative: ‘glfwInit’
gl3wInit();
^~~~~~~~
glfwInit
sb7.h:147:17: error: ‘gl3wIsSupported’ was not declared in this scope
if (gl3wIsSupported(4, 3))
^~~~~~~~~~~~~~~
sb7.h:147:17: note: suggested alternative: ‘gl3w_is_supported’
if (gl3wIsSupported(4, 3))
^~~~~~~~~~~~~~~
gl3w_is_supported
I also added #define GL3W_IMPLEMENTATION before #include "GL/gl3w.h" as suggested in the documentation of the single file version of gl3w but with no luck.
I get the same errors with the other book's source codes.
Hope that someone can help me.
Thank you.
