Hi, when running the test-suite I get plenty of the link errors (below). In order to resolve the missing symbols in Printer.thr_debug_o I was able to add -optl-L/usr/local/lib -optl-lbfd -optl-liberty to the ghc-6.6 command line. Note that "-L/usr/local/lib" is necessary, because otherwise the wrong libiberty.a file is found (namely that of gcc with a missing symbol "unlink_if_ordinary"). I don't know how to build this properly into the compiler (or a configure script). Cheers Christian /home/maeder/haskell/solaris/ghc-6.6/rts/libHSrts_thr_debug.a(Printer.thr_debug_ o): In function `DEBUG_LoadSymbols': /home/maeder/haskell/solaris/ghc-6.6/rts/Printer.c:997:0: undefined reference to `bfd_init' /home/maeder/haskell/solaris/ghc-6.6/rts/Printer.c:998:0: undefined reference to `bfd_openr' /home/maeder/haskell/solaris/ghc-6.6/rts/Printer.c:1002:0: undefined reference to `bfd_check_format_matches' collect2: ld returned 1 exit status
