[Lynx-dev] Building on MingW

[Gisle Vanem]

Hello list.

Trying to build the latest version with MingW showed some problems.
sleep() is in LYUtils.c, but inside a '!defined(__MINGW32__)'
section. My MingW doesn't have that function. But it do have _sleep()
marked as '__attribute__ ((__deprecated__))' in <stdlib.h>. Thus:

-------------------

Or I can do 'CFLAGS +=  -Dsleep=_sleep -Wno-deprecated-declarations'.

Then there's an issue with 'USE_ALT_BINDINGS'. I don't use it (what's it for?). 
Thus I needed this:

--- orig/src/LYEditmap.c       2013-11-29 00:52:56 +0000
+++ src/LYEditmap.c    2013-12-02 20:49:20 +0000

    for (j = 0; j < TABLESIZE(LYModifierBindings); ++j) {
       initLineEditor(&LYModifierBindings[j]);
    }
+#endif
}

-------------------

Then the most difficult line was in LYCurses.c (line 1756):
 bb = getbkgd(stdscr);

which expands to here:
 bb = ((SLcurses_Stdscr)->_bkgd)

This doesn't work in my SLang 2.2.x since it has no '_bkgd' in 
'SLcurses_Window_Type'. w/o knowing if this is correct, but patching 
this like:

--------------------

everything seems to work fine. I have no idea why MingW is treated specially in 
that
section. What about MSVC + SLang?
