#2493 GCC 15/Qt - ScintillaTypes.h: error: ‘intptr_t’ does not name a type

[Stefan Löffler]

When trying to compile the Qt version (qt/ScintillaEdit) with GCC 15.2.0 on Ubuntu 25.10, there's several errors, starting with

In file included from ScintillaDocument.cpp:13:
../../include/ScintillaTypes.h:700:18: error: ‘intptr_t’ does not name a type

This seems to be related to #2458 / c7ffad where this one files seems to have been missed.
The following patched fixed the issue for me:

Committed with [0b6476].

Original issue was [#2458].

Maybe the correct fix is to add the #include <cstdint> to ScintillaTypes.h instead of ScintillaDocument.cpp? Since ScintillaTypes.h is the place we actually require uintptr_t and intptr_t.

[Neil Hodgson]

Scintilla tries to avoid complex buggy nests of header dependencies by not using #include inside header files and specifying a global order of inclusion in scripts/HeaderOrder.txt.
