Describe the bug
I installed matplotplusplus using the following instructions from the official guide
mkdir build cd build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-O2" -DMATPLOTPP_BUILD_EXAMPLES=OFF -DMATPLOTPP_BUILD_TESTS=OFF sudo cmake --build . --parallel 2 --config Release sudo cmake --install .
on Ubuntu 22.04 system with g++ 12 and cmake 3.22 under Eclipse 2023-12 IDE
Steps to Reproduce
just create a new cmake project with defaults, create a simple default project with the following code
int main(int argc, char **argv) {
std::cout << "Hello World" << std::endl; std::vector<int> y = {2, 4, 7, 7, 6, 3, 9, 7, 3, 5}; matplot::plot(y); return 0;
}
and build it.
Output
