I have a 64-bit Cygwin environment. I'm trying to compile a 32-bit
(target) Windows program using i686-pc-mingw32-g++

-o NPOTAdlg.o NPOTAdlg.cpp

-lwininet NPOTA.o NPOTAdlg.o res/NPOTAdlg.res ../../library/library.a
/usr/i686-pc-mingw32/sys-root/mingw/lib/libwininet.a -o NPOTA
But I get this error on the link (last) step:
res/NPOTAdlg.res: file not recognized: File format not recognized
This program is a clone of another program I wrote a couple of years
ago (I wanted to re-use the Windows framework I had developed).
However, at that time, I was using 32-bit Cygwin, not 64-bit Cygwin.
Is there a work-around for this, other than re-creating a 32-bit
Cygwin environment?
Just a guess: your 64-bit windres is generating a 64-bit .res file that the
32-bit g++ can't grok. Look at 'windres -h'. There's a "-F" == "--target" flag
that can specify a target type. I would try adding "-F pe-i386" after the "-O
coff" on your command. If windres doesn't accept both -O and -F, try leaving
off the "-O coff" and just specify the -F flag and value. Good luck.
