[SOLVED] Error when using Magick++: unknown type name 'ssize_t'

I've just successfully(?) compiled Magick++ for my Windows 10 system, and I'm getting errors like these when I try to compile my program that uses it:

Code: Select all

What is included in your source code? I expect something like:

Code: Select all

#include <Magick++.h>
#include <string>
#include <iostream>
If you are directly including Color.h etc then that is the problem.

I did that, still having the same issue:

Did I muck up something while compiling IM?

IM source code includes sample CPP programs. Do they build correctly?

There are more errors, but they all involve ssize_t. >=20 errors, since make just stops trying after that. If you want I could pastebin the full log with -ferror-limit=0.

Okay, so the problem isn't in the source code, but in the building method. Sorry, I know nothing about the tools you use. Perhaps there is a flag to make the compiler POSIX-compliant, or something.

The Windows configure script auto-generates magick-baseconfig.h. It includes a define for ssize_t as follows:

Code: Select all

#if !defined(ssize_t) && !defined(__MINGW32__)
#if defined(_WIN64)
typedef __int64 ssize_t;
#else
typedef long ssize_t;
#endif
#endif

Well... I was using the .h files from my Unix machine. I assumed the includes are the same across platforms. I was mistaken. I've replaced the .h files in the demo/demo/include folder with the Windows ones I generated when compiling IM, and now it's no longer complaining about ssize_t!

Now it's giving warnings about redefined preprocessor variables and deprecated Windows Kit methods:

About the variable redefinitions, you might remember I've set those in my CMakeLists.txt:

I don't know why IM is overriding them. Is this a Windows quirk?
I think the getenv stuff is the demo program's fault though. It should probably be changed to _dupenv_s...

Yet another issue is that the linker, well, pukes at me about unresolved external symbols. However, I'm getting a similar issue to that on my Linux machine as well so I'll leave it to it's own thread.

Seeing my bump got removed, I'm just going to mark the thread as solved and make a a new thread for my new problem.

Thank you magick & snibgo.
