| For more information about the port or GLib, GTk+ and the GIMP to |
| native Windows, and pre-built binary packages, 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. Additionally the pthreads |
| emulation library is used. |
| |
| As for now, to build GLib on Win32, you need the Microsoft compiler |
| and tools. Both the compiler from MSVC 5.0 and MSVC 6.0 have been used |
| successfully. |
| |
| Before building you must get the pthreads library for Windows from |
| http://sourceware.cygnus.com/pthreads-win32/. Edit the location of the |
| pthreads library and include files in makefile.msc. Also edit the BIN |
| definition in makefile.msc. |
| |
| Build with `nmake -f makefile.msc`. Install with `nmake -f |
| makefile.msc install`. |
| |
| Support for building using the cygwin tools (without depending on the |
| cygwin runtime, i.e. "mingw32"), and maybe LCC-Win32 might be added |
| later. When using the cygwin 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 runtime), 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 windowing API (in the case of GLib, this |
| dimension isn't significant), regardless whether using a more or |
| less complete POSIX emulation runtime layer (like Cygwin) or not. |
| |
| - NATIVE_WIN32 is defined when compiling for Win32, *and* without |
| any POSIX 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 pthreads for Win32 package that the thread support uses isn't |
| released yet, and thus threads really should not be relied upon. |
