Re: Crosscompile

["Mikey" <jeffdb at netzone dot com>]

Attached are the shell scripts I wrote to use cygwin32 as a cross
linux/win95 compiler.

I tried to keep down disk space usage under both systems, so I used the
installed libs on my win95 system for the linux cross.

You'll have to edit the scripts to tell them where your cygwin32 source
tree lives, and where your vfat drives are mounted.

To use it this way, all system libraries must be in either
../cygnus-2.7.2-961023/
or H-i386-cygwin32/i386-cygwin32/lib, so I moved them all to H-...

ditto for the include files.

Unless you want to set up a linux cygnus libg++ you need a link in
/usr/include to your win32 include/g++ to compile c++ programs, the script
names this g++win32, and you have to remember to switch back and forth :^(,
or you could use -I

Your filesystems MUST! be mounted -b under cygwin32 before untaring the
header files under 95/NT to use the headers from all.tgz

Since linux/vfat dosen't understand cygwin32 symbolic links libc.a must be
copied to libg.a if you are using -g. ditto for curses/ncurses.

You might want to try it with, and without the %[cpp_cpu] in the linux
specs file, maybe it's just something wierd on my system.

typical command line

make CC=i386-cygwin32-gcc PATH=/usr/i386-cygwin32/bin:$PATH

This hasn't been tested extensivly, but I used the built compiler to
rebuild the libraries, and dll, and they seem to work. see SB.libs
