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

[dan9er]

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:

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?

[snibgo]

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.

[magick]

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

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

Code: Select all

# set some stuff for Magick++ so it doesn't yell warnings at us
add_compile_definitions(MAGICKCORE_HDRI_ENABLE=0 MAGICKCORE_QUANTUM_DEPTH=8)

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.

[dan9er]

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.
