| For more information about the port or GLib, GTk+ and the GIMP to |
| native Windows, see http://www.iki.fi/tml/gimp/win32/ . ("Native" |
| means that we use the Win32 API only, and not any POSIX emulation |
| layer except that provided by the Microsoft runtime C library, and the |
| pthreads emulation library.) |
| |
| As for now, only the Microsoft compiler and tools are really |
| supported. Before compiling, check the BIN definition in |
| makefile.msc. Compile with `nmake -f makefile.msc`. Install with |
| `nmake -f makefile.msc install`. Cygwin (without cygwin runtime, |
| i.e. "mingw32"), and maybe LCC-Win32 support will be added later. |
| |
| When using the cygwin compiler and tools *with* the cygwin runtime the |
| normal Unix configuration method should work as if on Unix (knock on |
| wood). |
| |
| With a little work, it might be possible to use the ./configure |
| mechanism also with a "mingw32" configuration. I.e. building GLib for |
| Win32 would use the cygwin tools (and dll), but the produced libraries |
| would not depend on the cygwin runtime being present. |
| |
| The following preprocessor macros are used for conditional compilation |
| related to Win32: |
| |
| - WIN32 is defined when compiling for the Win32 platform, regardless |
| if using the X11 or Win32 GUI API (of course, in the case of GLib, this |
| dimension isn't significant), regardless whether using a more |
| or less complete Unix emulation runtime layer (like Cygwin) or not. |
| |
| - NATIVE_WIN32 is defined when compiling for Win32, *and* without |
| any Unix emulation, other that to the extent provided by the |
| (Microsoft) C library, or the pthreads-win32 library. For instance, |
| pathnames use the native Windows syntax. |
| |
| - _MSC_VER is defined when using the Microsoft compiler. |
| |
| Currently the Win32 port uses the combination with all three of those |
| on, but eventually the cygwin compiler and tools will be supported |
| also, and in that case _MSC_VER wouldn't be defined. |
| |
| Some of the usage of these macros is probably a bit mixed up, and will |
| have to be straightened out when actually trying other combinations. |
| |
| The thread support uses the pthreads for Win32 package available from |
| http://sourceware.cygnus.com/pthreads-win32/, which isn't ready yet, |
| and thus really should not be relied upon. |
