DISCLAIMER: (I' am a newbie)
Hello I heard somewhere that dosemu-0.66.7 can run the adsp a2181
compiler and linker (namely g2 and ld21). These are tools that are based
in an ancient version of gcc. I tried dosemu-0.99.6 the latest I could
compile and failed. From what I know g21 uses dpmi.
The question is what option should I use for debugging? -D+M gives a lot
of messages but is it really dpmi related?. Does a later version of
dosemu copes with this problem? or it is the first time you have ever
heard of? If not please excuse my ignorance but I checked over the list
archive for the Mars and Feb and I didn't find anything relative.
.Bill
PS. I found the solution in the compilation problems __needs_timeval. I
will try 0.99 now. Should I keep you informed?
