Compiler : gcc-12 on wsl2 linux on windows

alandefreitas commented 1 year ago

Is that using the master branch? GCC12 is being tested in CI

https://github.com/alandefreitas/matplotplusplus/actions/runs/5318331589/jobs/9629701081

suhasghorp commented 1 year ago

Yes, I am using master branch. When I re-built the package using system build presets, I worked and I have the library successfully built. However, when I try to save a test plot I get following error. I am on Ubuntu 20 on WSL2 (windows subsystem for Linux) which does not have any X windows server running, which is why I am "saving " the plot and not "showing" it.

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

std::vector<double> x = matplot::linspace(0, 2 * matplot::pi);
std::vector<double> y = matplot::transform(x, [](auto x) { return sin(x); });
matplot::plot(x, y, "-o");
matplot::hold(matplot::on);
matplot::plot(x, matplot::transform(y, [](auto y) { return -y; }), "--xr");
matplot::plot(x, matplot::transform(x, [](auto x) { return x / matplot::pi - 1.; }), "-:gs");
matplot::plot({1.0, 0.7, 0.4, 0.0, -0.4, -0.7, -1}, "k");
matplot::save("./test.png", "png");

I have tried with jpg format as well.

When I was building the package, I got warningd (?) like below, so I am not sure if PNG is even supposed to work in my environment.

Setting global options
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.2")
-- Found JPEG: /usr/lib/x86_64-linux-gnu/libjpeg.so (found version "80")
-- Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR)
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.11")
-- Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)

Thank you.

Yes. Your error looks problematic because

/usr/include/c++/12/bits/std_function.h:405:42: error: ‘*(std::function<bool(char)>*)((char*)&__tmp + offsetof(std::__detail::_StateT, std::__detail::_State<char>::<unnamed>.std::__detail::_State_base::<unnamed>)).std::function<bool(char)>::_M_invoker’ may be used uninitialized [-Werror=maybe-uninitialized]

is a maybe-uninitialized error inside the STL. That's not supposed to happen unless there's some serious incompatibility between your compiler and the std library you're using.

alandefreitas commented 1 year ago

which is why I am "saving " the plot and not "showing" it.

The library depends on gnuplot for doing that. I don't know how to fix it, but basically if you can ensure gnuplot can save it in the environment you set up, then matplot will be able to save it as well.
