Compilation Error Involving StatusOr and Status Classes in Draco Library

[jianxiapyh]

Hi,

I am currently integrating the Draco library into our system and am facing a compilation error related to the StatusOr class. This issue arises when I include the "draco/io/ply_reader.h" in one of the header files.

Error Description:

The compilation error seems to be a type conversion issue involving the Status class. Here are the error messages:

usr/local/include/draco/core/status_or.h:38:30: error: no viable conversion from 'draco::Status' to 'int'
  StatusOr(const T &value) : status_(OkStatus()), value_(value) {}
                             ^       ~~~~~~~~~~
/usr/local/include/draco/core/status_or.h:39:25: error: no viable conversion from 'draco::Status' to 'int'
  StatusOr(T &&value) : status_(OkStatus()), value_(std::move(value)) {}
                        ^       ~~~~~~~~~~
/usr/local/include/draco/core/status_or.h:53:35: error: member reference base type 'const int' is not a structure or union
  bool ok() const { return status_.ok(); }

Environment:

• OS: Ubuntu 20.04
• Compiler: Clang 10
• Draco Version: Latest version from [specific branch or commit hash if applicable]

Current Workaround:

I have temporarily bypassed the problem by hardcoding certain values, but I am seeking a more robust and permanent solution.

Could you please provide some guidance on how to resolve this issue?

Thanks for your help!

It may be that your code somewhere defines a macro similar to #define Status int . Can you try adding

#ifdef Status
#undef Status
#endif

before you include any Draco header?
You can also try to include the Draco header before you include any header of your project.

Thank you, it seems I have code that defines Status earlier. Issue Closed.
