Undefined reference from loadFromFile

[zedong]

Hello, I just recently tried to compile my project as a windows .exe.

Linking the sfml lib worked fine, and the test project from the tutorial page worked fine, however, when I try to compile my project, it complains about every single loadFromFile is undefined.

Using gcc 9.4.2 with SFML 2.4.2 in Code::Blocks.

The message I get is:
C:\Users\Kristian\Desktop\project\vk\Menu.cc|202|undefined reference to `sf::Texture::loadFromFile(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, sf::Rect<int> const&)'|

Thanks in advance.

Edit: It compiles just fine if I comment out every single loadFromFile, but obviously that just leaves me with a blank window.

You're probably using a different compiler than the one that was used to compile the SFML binaries. The compilers need to match 100%.
Either build SFML yourself with your compiler (it's easy!) or check the download page to see which compilers have been used for the provided binaries.

Using the gcc TDM 4.9.2 linked from http://www.sfml-dev.org/download/sfml/2.4.1/.

Maybe you build your project with C++11 but SFML is not built with C++11 (there have been a change in the ABI of the GCC standard lib with C++11).

I've tried both with and without -std=c++11 with the same result unfortunaly.

Make sure the actual build command doesn't contain a -std=c++11 anymore. Sometimes these settings are rather hidden.

Otherwise try to rebuild SFML with -std=c++11.

Or alternatively update your compiler to another one listed on the download page and get the respective binaries.
