This happens with both nhc98 1.16 and 1.18: $ cat Q.hs module Q () where import Control.Monad (liftM2) newtype A a = A a $ nhc98 -c Q.hs nhc98comp: isRealData InfoClass 1 Prelude.Monad IEnone \/ b . (1 b) [38,39,40,41] [] [(5,([],[])),(25,([],[])),(26,([],[]))] Thanks Ian

Packages in a gcc build of nhc98
by Gregory Wright 28 Mar '05

28 Mar '05

Hi, When building nhc98 using gcc on Mac OS X, none of the packages are built. However, when building using ghc as a compiler, the packages are built. When bootstrapping from gcc, is it necessary to rebuild the system using the newly generated nhc98? The documentation is seems to be silent on this. Best Wishes, Greg

nhc98 1.18, gcc 3.4 and FC3
by Gérard Milmeister 28 Mar '05

I cannot compile nhc98 1.18 on Fedora Core 3 with gcc 3.4.3. The same was the case with nhc98 1.17 and 1.16. Here is the problem: /home/gemi/Projects/fedora/BUILD/nhc98-1.18/script/nhc98 -c +CTS -lib - redefine -CTS +RTS -H32M -RTS - o /home/gemi/Projects/fedora/BUILD/nhc98-1.18/targets/ix86- Linux/obj/prelude/DErrNo/DErrNo.o DErrNo.hs OS allocated a heap in high memory (>0x80000000) which breaks this program's run-time system. hpStart=0xb7e5e008, hpEnd=0xb7ed3308 OS allocated a heap in high memory (>0x80000000) which breaks this program's run-time system. hpStart=0xb7f32008, hpEnd=0xb7fa7308 OS allocated a heap in high memory (>0x80000000) which breaks this program's run-time system. hpStart=0xb7e84008, hpEnd=0xb7ef9308 OS allocated a heap in high memory (>0x80000000) which breaks this program's run-time system. hpStart=0xb04bd008, hpEnd=0xb7ee2888 make[1]: *** [/home/gemi/Projects/fedora/BUILD/nhc98-1.18/targets/ix86- Linux/obj/prelude/DErrNo/DErrNo.o] Error 1 -- Gérard Milmeister Langackerstrasse 49 CH-8057 Zürich

Build failure of nhc98-1.18 on Mac OS X 10.3.8 with gcc 3.3
by Gregory Wright 15 Mar '05

15 Mar '05

Hi, I've encountered a build failure of nhc98 1.18 on Mac OS X 10.3.8 using Apple's gcc 3.3. The build fails with a bus error, as can be seen in the attached log. GHC is not installed; the build is using gcc. The build was done with 'ulimit -s unlimited' set and also used gnu make 3.79. The build is part of the darwinports infrastructure on Mac OS X, which builds software from source in the manner of the FreeBSD ports collection. The build commands were: CC=gcc ./configure --buildwith=gcc --mandir=/opt/local/share/man ulimit -s unlimited && make Can anyone tell me if I've done something blindingly stupid? Please cc me as I am not subscribed to the nhc lists. Thanks! Best Wishes, Greg Wright

The configure script (and others?) doesn't manage properly the working directory

Thanks for the fast reply! Here is another bug.

Nhc98 doesn't really implement it. Try class C a where twist :: a -> a instance C (a,a) where twist (x,y) = (y,x) main = print (twist ('a',True)) which is incorrectly accepted, causing runtime trouble. Also, the other two examples in that section of the Report cause compile-time crashes: instance C (Int,a) instance C [[a]]
