74 /* Note from Angus, 17 Jan 2005:
76 * The code below is taken verbatim from Ruurd's original patch
77 * porting LyX to Win32.
79 * Windows allows us to define LyX either as a console-based app
80 * or as a GUI-based app. Ruurd decided to define LyX as a
81 * console-based app with a "main" function rather than a "WinMain"
82 * function as the point of entry to the program, but to
83 * immediately close the console window that Windows helpfully
84 * opens for us. Doing so allows the user to see all of LyX's
85 * debug output simply by running LyX from a DOS or MSYS-shell
88 * The alternative approach is to define LyX as a genuine
89 * GUI-based app, with a "WinMain" function as the entry point to the
90 * executable rather than a "main" function, so:
92 * #if defined (_WIN32)
93 * # define WIN32_LEAN_AND_MEAN
94 * # include <stdlib.h> // for __argc, __argv
95 * # include <windows.h> // for WinMain
98 * // This will require the "-mwindows" flag when linking with
100 * // For MSVC, use "/subsystem:windows".
101 * #if defined (_WIN32)
102 * int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
104 * return mymain(__argc, __argv);
108 * where "mymain" is just a renamed "main".
110 * However, doing so means that the lyxerr messages would mysteriously
111 * disappear. They could be resurrected with something like:
115 * freopen("conin$","r",stdin);
116 * freopen("conout$","w",stdout);
117 * freopen("conout$","w",stderr);
120 * This code could be invoked (say) the first time that lyxerr
121 * is called. However, Ruurd has tried this route and found that some
122 * shell scripts failed, for mysterious reasons...
124 * I've chosen for now, therefore, to simply add Ruurd's original
127 // Close the console when run (probably)
128 // not run from command prompt
