Describe the bug

Hi,

Firstly, thanks of all for this package. I am coming from matplotlib and this looks like a nice transition. I have some issues compiling code with this package however. Using g++-11 (gcc (GCC) 11.2.0) I am getting link errors and undefined symbols. The instructions clearly state that c++17 is supported, compiling with g++-10 yields compiling errors (see block below). Could you point me in the right direction? Thanks in advance! Steps to Reproduce

cd matplotplusplus/ && mkdir build && cd build
cmake .. && make -j 12 && make install .
 g++-10 ~/test.cpp -o test -I /usr/include -L /usr/lib

where test.cpp is

#include <cmath>
#include <matplot/matplot.h>

int main() {
    using namespace matplot;
    show();
    return 0;
}

Output

alandefreitas commented 2 years ago

The errors are basically saying the C++17 features, such as is_same_v and string_view, are missing. If the compiler supports C++17, you might need to turn on the C++17 flags manually or via CMAKE_CXX_STANDARD when calling CMake.

cvanelteren commented 2 years ago

I set c++ stdlib with set(CMAKE_CXX_STANDARD 17) in CMakeLists.txt. After that I am getting missing symbols. Not sure how to debug the linkage error.

` g++ -std=c++17 -I/usr/local/include/ test.cpp -I/usr/include -o test ` ``` /bin/ld: /tmp/ccdsu2Ex.o: in function `matplot::show()': test.cpp:(.text._ZN7matplot4showEv[_ZN7matplot4showEv]+0x20): undefined reference to `matplot::gcf()' /bin/ld: test.cpp:(.text._ZN7matplot4showEv[_ZN7matplot4showEv]+0x34): undefined reference to `matplot::figure_type::show()' collect2: error: ld returned 1 exit status ```

alandefreitas commented 2 years ago

g++ -std=c++17 -I/usr/local/include/ test.cpp -I/usr/include -o test

You're not linking the library. Thus, the symbols are missing. See -L compiler option or use CMake for integration. Also make sure you are using the same compiler you used to build matplot++.

cvanelteren commented 2 years ago

I got it to compile and run g++ -o test test.cpp /usr/lib/libmatplot.a /usr/lib/Matplot++/libnodesoup.a /usr/lib/libtiff.so /usr/lib/libjpeg.so /usr/lib/libz.a /usr/lib/libpng.so

I am not entirely sure why linking with -L didn't work. I take it that the preferred method is to use cmake for generating plots and not one-off scripts using method above?

alandefreitas commented 2 years ago

Yes. Having a build system is almost always the preferred method.

cvanelteren commented 2 years ago

Thanks for the help, will take this package for a spin.
