nethack build failure

[tietze@…]

I tried to do a port install nethack and it came up with the below errors. It works nicely in the shell when trying the variant +x11 (port install nethack +x11).

Regards, Jørgen.

The original report appears to be some variant on the Tcl env bug (#13930); if you cd into work/nethack-3.4.3 and run env CC= make all you should see the same errors. Also, if you simply try running port again, it seems to build fine.

The second issue reported by Eridius can be fixed by using -O2 instead of -O, the following Portfile diff does this:

Very cool after editing the Portfile the directory reported by "port dir nethack" and installing two times it build without problems :-) Great!

I am unable to reproduce the issue with nethack 3.4.3_2 as it exists in the repository today, with Mac OS X 10.4.11 and Xcode 2.5 on Intel. If you still experience the problem, please provide more details about your setup.

The issue Eridius reported still exists on 10.5.4/Xcode 3.1/Intel:

cc -O -I../include   -c -o mkmaze.o mkmaze.c

The initial issue (make[2]: O: Command not found) is the Tcl env bug, tracked in #13930. The fix to the "unable to find a register" issue was committed in r41601 (maintainer timeout).
