This emulator, which I call wm-FPU-emu, is in fact a slightly modified
wm-FPU-emu which I wrote for the Linux operating system. That emulator
is based upon an older emulator which I wrote for use with djgpp.
Released versions:
for djgpp 1.11 wm-FPU-emu version Beta 1.11d April 1994
for djgpp 1.11 maint5 wm-FPU-emu version Beta 1.11d2 July 1994
If you merely want to use the FPU emulator, move the file emu387 to
where go32 expects to find it. See the djgpp documentation for more
detail on installing and using emu387.
If you want to look at the source for the emulator, you will find it
in the file wmfpu112.tgz which is a gzip-compressed tar archive. Use
gunzip and tar to extract the files.
If you wish to compile the emulator, you should be aware that the
emulator source is set up for compiling on the Linux operating system.
It is conceivable that it will compile with few problems on other
operating systems such as OS/2 or even ms-dos. For Linux, I suggest
moving wmfpu112.tgz to the root directory and then:
cd /; tar xpvfz /wmfpu112.tgz '*/wm-FPU-emu/*'
which assumes that you already have the Linux kernel sources installed,
otherwise simply do:
cd /; tar xpvfz /wmfpu112.tgz
then:
cd /usr/src/djgpp/wm-FPU-emu
and read the README.
A copy of the GNU General Public License may be found in wmfpu112.tgz
as the file
./usr/src/djgpp/wm-FPU-emu/COPYING.
A discussion of the performance and limitations of the emulator can
be found in wmfpu112.tgz in the file
./usr/src/linux/drivers/FPU-emu/README.
