Can't find libpq library for C++ program using libpqxx - c++

I'm not a C++ developer and I don't know very much about compiling projects or makefiles, but I'm trying to compile and run someone else's C++ program. I'm using Ubuntu. Here's the makefile I have so far, based on this:
TARGET_EXEC ?= a.out
BUILD_DIR ?= ./build
SRC_DIRS ?= ./src
SRCS := $(shell find $(SRC_DIRS) -name *.cpp -or -name *.c -or -name *.s)
OBJS := $(SRCS:%=$(BUILD_DIR)/%.o)
DEPS := $(OBJS:.o=.d)
INC_DIRS := $(shell find $(SRC_DIRS) -type d)
INC_FLAGS := $(addprefix -I,$(INC_DIRS))
CPPFLAGS ?= $(INC_FLAGS) -MMD -MP
CC = gcc

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.

grpc core undefined references for c++ grpc v1.50?

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.)
the failed command
/usr/bin/c++ -Werror -g xxxx/my/client/CMakeFiles/my_client.dir/my_client.cc.o \
-o /tmp/my_client -W xxxx/my/proto/libmy_core.a /usr/local/lib/libgrpc++_reflection.a \

How to fix multiple definition of main building gtest project using make on ubuntu [duplicate]

This question already has an answer here:
Linking issue with GCC 4.6.1
(1 answer)
Closed 1 year ago.
I wanted to build a gtest project on linux using just a makefile, ie not using cmake. I followed along the tutorial here:
http://www.yolinux.com/TUTORIALS/Cpp-GoogleTest.html
But getting multiple definition of main errors - see below.
I am on ubuntu v20.04
angus#angus-VirtualBox:~/Documents/code/gtest_make_only/test/src$ uname -a
Linux angus-VirtualBox 5.11.0-38-generic #42~20.04.1-Ubuntu SMP Tue Sep 28 20:41:07 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
I installed gtest like this:
git clone https://github.com/google/googletest.git
mkdir build
cd build
sudo snap install cmake --classic
cmake .. -DBUILD_GMOCK=OFF
make
sudo make install
If I now look on my system I have
/usr/local/include - with gtest directory with header files
/usr/local/lib - contains libgtest.a and libgtest_main.a
I modified the Makefile in the example to be like this:
CXX = g++
CXXFLAGS = -g -L/usr/local/lib -lgtest -lgtest_main -lpthread
INCS = -I./ -I../../src -I/usr/local/include
OBJS = ../../src/Addition.o Addition_Test.o ../../src/Multiply.o Multiply_Test.o
testAll: $(OBJS)
$(CXX) $(CXXFLAGS) $(INCS) -o testAll Main_TestAll.cpp $(OBJS)
.cpp.o:
$(CXX) $(CXXFLAGS) -c $< -o $# $(INCS)
clean:
rm testAll *.o testAll.xml
I also had to tidy up the code sample - eg where in code has Addition.h - have to change to Addition.hpp which is the filename.
The build error below. How to fix this?
I did try by removing -lgtest_main from the Makefile, but then get error:
/home/angus/Documents/code/gtest_make_only/test/src/Main_TestAll.cpp:5: undefined reference to `testing::InitGoogleTest(int*, char**)'

makefile example to use soplex

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:

I think that there must be a problem linking the libraries of gmp, can anybody please help me?
The library gmp is here:
fabio#canarino3:~/Dropbox/WORKING/SETUP_BPP_CODE/soplex-5.0.1/buid$ grep gmp soplex-targets.cmake
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"
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!!!!

Compiler not finding jpeg and png libraries

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.

How to fix "undefined reference to `YAML::operator<<(std::ostream&, YAML::Node const&)'" in cmake

I did a project in manjaro, then decided to switch to ubuntu and everything flew to hell. I've installed libpoco-dev, libtinyxml2-dev and libyaml-cpp-dev
my cmakelist file:
cmake_minimum_required(VERSION 3.13)
project(auchan_handler_microservice)
set(CMAKE_CXX_STANDARD 17)
set(GCC_COVERAGE_COMPILE_FLAGS "-Wall -Werror")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
set(LIB_DIR "${PROJECT_SOURCE_DIR}/extern")
add_executable(auchan_handler_microservice main.cc)
include_directories(src)
add_subdirectory(src)
option(PACKAGE_TESTS "Build the tests" ON)
if (PACKAGE_TESTS)
enable_testing()
add_subdirectory(tests)
endif ()
