hat error
by Amanda Clare 17 Jul '02

17 Jul '02

I get the following error message from hat's internals: legion:haskell> hmake -hat SimonGA hat-trans SimonGA.hs Fail: AuxFixity.hs:92: Non-exhaustive patterns in case The program compiles fine under nhc and ghc without hat. Amanda I would attach the file that caused this but it's not mine - though I can ask if you need it.

reading negative Doubles
by Amanda Clare 17 Jul '02

17 Jul '02

Is it possible that the instance of "read" for Doubles when using hat can't handle negative numbers? I get "Error: Prelude.read: no parse" whenever I have a negative number to read. My program works fine without hat. Amanda

I get the same error from both nhc98 and ghc when trying to use hat on solaris. Do you know what I'm likely to be missing? legion:haskell> hmake -hat Insort hat-trans Insort.hs Wrote TInsort.hs /dcs/biorepos/FuncProg//bin/nhc98 -c -package hat -o TInsort.o TInsort.hs /dcs/biorepos/FuncProg//bin/nhc98 -package hat -o Insort TInsort.o Undefined first referenced symbol in file ntohl /dcs/biorepos/FuncProg//lib/nhc98/sparc-solaris2/libHShat.a(hat.o) htonl /dcs/biorepos/FuncProg//lib/nhc98/sparc-solaris2/libHShat.a(hat.o) ld: fatal: Symbol referencing errors.

Also, just for future, the echo.c prog to simulate echo was missing from the scripts directory when installing hat, so I used the one from nhc98. Amanda

using hmake with hat
by Hal Daume III 27 Jun '02

27 Jun '02

Hi, I'm just getting in to this hat thing and am experiencing a slight difficulty. My directory structure looks like .../projects .../projects/SemGraph .../projects/Util .../projects/NLP .../projects/FGL ... I'm in the SemGraph directory and am hmaking a program named AlignGraph. Inside Util there is a modeule Util.STM which is used in AlignGraph. I have ".." in my path when I hmake, and when I don't do hat, everything works fine. However, when I do use hat, hmake seems to look int the wrong place for the generated files: 9:16am moussor:SemGraph/ hmake -ghc AlignGraph.hs -I../FGL -I.. -package data -cpp -fvia-c -fglasgow-exts -hat hat-trans ../Util/STM.hs Wrote ../Util/TSTM.hs ghc -package data -cpp -fvia-c -fglasgow-exts -I../FGL -I.. -i../FGL -i.. -c -package hat -o ../TUtil/STM.o ../TUtil/STM.hs ghc-5.02.3: file `../TUtil/STM.hs' does not exist so it seems hat is creating ../Util/TSTM.hs, but hmake prepends the "T" to "Util" instead of "STM". This seems to be a hat problem; even though it creates Util/TSTM.hs, the name of the generated module is "TUtil.STM". Any suggestions on what to do about this? I can't imagine people haven't hit this wall before... - Hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

Thanks. I made a rpm package with ghc-5.02.3 built on a Red Hat 7.3-ish environment and put it at http://haskell.org/~petersen/rpms/i386/hat-2.00-1.i386.rpm Since the docs are rather large, I put them in a separate subpackage gzipping the ps and pdf files http://haskell.org/~petersen/rpms/i386/hat-doc-2.00-1.i386.rpm and the source rpm file is: http://haskell.org/~petersen/srpms/hat-2.00-1.src.rpm Jens

Re: [Hat] Installing Hat for _both_ ghc and nhc98

It discovers the actual location of either ghc or nhc98 on the final machine, and installs only the `hat' package directly into the compiler tree. It looks like maybe you should call script/confhat from the rpm spec file, but not from `configure --install'? > I suppose this would also be a problem for making a binary release of > hat. It will be difficult to make binary releases of Hat anyway, because the library and interface files depend intimately on the exact version of the ghc compiler used to build them. > For now, I'll just do the installing by hand in my rpm spec file. This is probably the easiest approach. Would you like me to add your .spec file to the CVS repository? Regards, Malcolm

Installing Hat for _both_ ghc and nhc98
by Martin Norbäck 20 Jun '02

20 Jun '02

What is the best way to install Hat for both ghc and nhc98? I'm building RPMS, because I find it the best way to install programs on a lot of machines here at work .Already did nhc98, see http://www.dtek.chalmers.se/%7ed95mback/nhc98 Now to hat. I want hat both for ghc and nhc98. My idea was to build separate packages, hat-ghc and hat-nhc98. The common files (the hat binaries) would be put in the hat package. However, it seems that the hat binaries are built differently when building for ghc and nhc98. Which set of binaries should I choose?
