BTW, the minidocx-0.6.0.tar.gz file works fine.

[totravel]

C++20 compilers are required to build minidocx 1.0.

[l1t1]

I use GCC 14.2 GCC 14 Release Series. May 23, 2025. it should support c++20, how to set it in makefile？

[l1t1]

I add #include <cstring> in package.cpp, the errors of package.cpp are gone. It now shows

I add #include <algorithm> in string.cpp, it still shows

[Aurora1949]

I encountered the same problem. After inserting the header file, I also modified this file:

// src/utils/string.cpp
namespace MINIDOCX_NAMESPACE
{
  std::string removeSpaces(std::string str) {
    std::string tmp{ std::move(str) };
    tmp.erase(std::remove_if(tmp.begin(), tmp.end(), [](unsigned char c) { return std::isspace(c); }), tmp.end());
    return tmp;
  }
}

Now, I can compile the target minidocx without any errors.

However, I am still unable to build any example demos. I get the following error:

include/minidocx/word/main/document.hpp:9:10: fatal error: config.hpp: No such file or directory
    9 | #include "config.hpp"
      |          ^~~~~~~~~~~~

I am using MSYS2 GCC 15.1.0.

[killerswin2]

@Aurora1949 that build error is because include/minidocx is a PRIVATE include for minidocx's target, The temp solution for building the examples to change that PRIVATE to a PUBLIC, or modify the example's cmakefile to look at "include/minidocx" and "include"
