I'm attempting to install g++ 1.35.0 on our Convex C-220 running Convex Unix release V7.0. The makefile barfs when compiling newld.c. An exerpt from the make output: gcc version 1.35 ../gcc/cpp -v -DTARGET=-1 -DSTANDARD_SEARCH_DIRS="/mnt/adc/lib", "/lib", "/usr lib", "/usr/local/lib" -DSOS -DESKIT -DSOS -DESKIT -undef -D__GNUC__ -Dconvex - parsec -Dunix -D__convex__ -D__parsec__ -D__unix__ newld.c /tmp/cc001716.cpp GNU CPP version 1.35 ../gcc/cc1 /tmp/cc001716.cpp -quiet -dumpbase newld.c -g -version -o /tmp/cc00 716.s GNU C version 1.35 (convex) compiled by GNU C version 1.35. newld.c: In function enter_file_symbols: newld.c:1807: invalid use of undefined type `struct nlist' and so on... Anybody have any idea what's going on? Alan D. Cabrera adc@cpsvax.cps.msu.edu

No flavor of GNU ld will work easily on a Convex because the a.out format isn't right. Here's an ld++ program that runs /bin/ld. If you have Icon, you can just run it, otherwise I guess you have to write something equivalent. Touch newld.o and ld++ in the g++ build directory (to shut make up), and install this as /usr/local/lib/ld++. (PS: there is a gotcha in stream.cc -- convex _doprnt returns void, not a status indication, so take out the "stat = " part of the "stat = _doprnt ..." line, and add "stat = <the right thing>". Let me know if you figure out what the right thing is... I'm using 0 for now.) ---------- ld++.icn ---------- procedure main (argv) # Get scratch file names pid := read (open ("echo $$", "p")) | stop ("can't read pid") codefile := "/tmp/" || pid || ".out" hookfile := "/tmp/" || pid || ".o" # Scan args.
