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