Marko,
another successful step, now it builds this far:
[..] nhc98 +RTS -K10M -RTS +CTS -H20M -CTS -c -d /var/tmp/src/nhc98-1.10/targets/ix86-FreeBSD/obj/hat HatTrace.gc Warning unrecognized run-time flag -K10M ignored.
==================================== Error when renaming:: Type constructor ForeignObj defined 2 times. gmake[1]: *** [/var/tmp/src/nhc98-1.10/lib/ix86-FreeBSD/hat-observe] Error 1 gmake[1]: Leaving directory `/var/tmp/src/nhc98-1.10/src/tracer/hat' gmake: *** [lib/ix86-FreeBSD/hat-stack] Error 2
I think you probably already have an older version of nhc98 installed, and this part of the build is using the old version. If you `make install' the 1.10 version, then `make' again, I believe it should complete the build correctly. Then you can `make install' a second time. Regards, Malcolm
