I just added this library in my C++ project and I got this compilation time error:

/home/nyck/Desktop/maia/maia_app/maialib/include/miniz-cpp/zip_file.hpp:5583: error: invalid conversion from ‘std::size_t (*)(void*, uint64_t, const void*, std::size_t)’ {aka ‘long unsigned int (*)(void*, long unsigned int, const void*, long unsigned int)’} to ‘mz_file_write_func’ {aka ‘long unsigned int (*)(void*, long long unsigned int, const void*, long unsigned int)’} [-fpermissive]

What can I do to fix it?

  • Ubuntu 20.04 x64
  • GCC 9.3
  • Qt 5.15.0

Hi, I got the same error 3 years later...
Is there a way to fix it?
