Dear Richard,
I had a try, but not a successful one, to make gcc on a decstation3100.
The compiler was created without any problems but the compare of the
two versions of the compiler-compiling by the cc-compiled and gcc-compiled
gcc was not o.k. What do you think about it. Let me know, if you have
any idea, what's to do.
I have appended the output of the comparison and the history of the
last 40 command's with some comments marked by //.
My adress is harlan@ux1.lbl.gov.
Thanks and many greetings
Magnus Harlander

This looks like it might be another case of comparing coff files without realizing that there are timestamps and temporary file names embedded in ecoff object files. The ecoff-cmp script provided with gcc should be used to compare ecoff object files. What version of the compiler are you using and what script did you use to compare the files with. I've tried gcc on the decstation3100 a few times and didn't have these particular problems. -- Peter Ham PO Box 3430 (h)(415) 322-4390 MS Computer Science Student Stanford, CA ham@cs.stanford.edu Stanford University 94309 (o)(415) 723-2067
