Object file is put in wrong directory when any source has absolute path

Files: /tmp/e/A.hs, /tmp/e/dep.c. Current dir: /tmp/e.

ghc -odir /tmp/xyzzy A.hs dep.c: works as expected, puts dep.o in /tmp/xyzzy.

But try to prefix either A.hs or dep.c (or both) with /tmp/e/, and suddenly dep.o is put in /tmp/e, not in /tmp/xyzzy.

Couldn't check with 8.2.1 yet.

With 8.4.2 this error can be reproduced. I'll try to fix it.

This bug has nothing to do with absolute pathes!

As soon as you specify the dep.c with a directory (different from ./)

ghc -odir myodir A.hs subdir/dep.c

then GHC will write the dep.o file to myodir/subdir/dep.o . The bug occurs only if the dependent file is a *.c (or similar) file.

I'll develop a new solution,just fixing the issue with the absolute path. I'll not change the difference with the use of subdirectories in odir between *.hs and *.c source files. Using again original ticket title.

I stopped working on this ticket.
