yes, it is possible!
I am running my own Application, which is written in 4gl, running under an INFORMIX-Version of the year 1989 !
And it works. Operating systems: RedHat 7.3 with kernel 2.4.18 and
I do not know, which kernel RedHat8 uses. You have to make a kernel-patch which fits to your kernel-version.
for kernel 2.4.20 I downloaded linux-abi-126.96.36.199.patch.gz.
this patch gives my operating-system the possibility to run SCO-binaries.
Unfortunatly the linux-ABI-project is not yet up to date with the latest LINUX-kernels. I do not know if thies project will be done furtheron.
Now I am using Mandrake 10.0 with the kernel 2.6 which has got fine new features, but now I cannot use my SCO-Application. I am waiting for the new linux-ABI for kernel 2.6.
Did you make your own kernel-patch before? If not, dont bother, it is easy.
