I've just added the --print-libdir option to GHC, and I'll try to sneak it into 5.02.1. Cheers, Simon

Error compiling nhc98-1.10 in Linux

Hello. When compiling nhc98-1.10 on my Red Hat Linux 7.2 box with ghc-5.02 (after applying the patch that enables the detection of ghc) compilation stops with an error message: $ ./configure --prefix=/usr --mandir=/usr/share/man/man1 --docdir=docs_/docs +docs --buildwith=ghc --buildopts=-O [...] $ make 'OPT=-O2 -march=i386 -mcpu=i686' all [...] /home/romildo/rpms/BUILD/nhc98-1.10/script/hmake -nhc98 -K10M +CTS -H20M -CTS Hatobserve /home/romildo/rpms/BUILD/nhc98-1.10/targets/ix86-Linux/obj/hat/hatlib.a -d/home/romildo/rpms/BUILD/nhc98-1.10/targets/ix86-Linux/obj/hat hmake: Sorry, I do not know about your installation of nhc98 make[1]: *** [/home/romildo/rpms/BUILD/nhc98-1.10/lib/ix86-Linux/hat-observe] Error 1 make[1]: Leaving directory `/home/romildo/rpms/BUILD/nhc98-1.10/src/tracer/hat' make: *** [lib/ix86-Linux/hat-stack] Error 2 Any clues?

Here is the essential part of the patch: - GHCDIR=`grep '^libdir' ${whichGHC} | head -1 | sed 's/^libdir=.$.*$./\1/'` + GHCDIR=`grep '^TOPDIROPT' ${whichGHC} | head -1 | sed 's/^TOPDIROPT="*-B$[^";]*$.*/\1/'` However, this does not work on my (Slackware Linux) machine. In the driver script for ghc-5.02, I see the following two lines: libdir='/usr/malcolm/local/lib/ghc-5.02' TOPDIROPT="-B$libdir"; which means that the original confhc gives the correct path (/usr/malcolm/local/lib/ghc-5.02), but the patched confhc gives an incorrect path symbol ($libdir). Can someone at ghc central confirm whether this part of the ghc-5.02 driver script differs, depending on package and platform? And if so, what is the best way to detect which variation applies?

profiling

Hi, I am using linux binaries on red hat 7.1. Compiling for time profiling I get undefined reference to `FN_Char_46intToDigit' Compiling for heap profiling has no problem, but seg faults on run. What is wrong? IS there a RPM for redhat? Thanks, Saswat [saswat@cf-plslab9 Oct17]$ nhc98 -98 Types.hs Operators.hs Mutables.hs Primitives.hs Pattern.hs CPL.hs Main.hs -o Main -t /usr/local/lib/nhc98/ix86-Linux/Numeric.z.a(ShowIntBase.z.o)(.data+0x12c): undefined reference to `FN_Char_46intToDigit' collect2: ld returned 1 exit status [saswat@cf-plslab9 Oct17]$ rm *.o *.hi -f [saswat@cf-plslab9 Oct17]$ nhc98 -98 Types.hs Operators.hs Mutables.hs Primitives.hs Pattern.hs CPL.hs Main.hs -o Main -p [saswat@cf-plslab9 Oct17]$ ./Main +RTS -H4M -p -RTS 82853 32974.9531 Segmentation fault (core dumped)

Re: [nhc-users] hat-observe message

> Why do I get the following message from hat-observe? There is enough > output for hat-trail to work ok. > > [ajc99@pcburum hier]$ hat-observe countAssocs HierLearn > FUNCTION TABLE EMPTY > Closing file 0 Is the module containing `countAssocs' written as a literate file? Or maybe using an indentation style where top-level identifiers are indented by one character or more? If so, then I guess this is probably a known problem that we have already fixed for the forthcoming release 1.10 (due approximately at the end of this week). Essentially, hat-observe can only sensibly report information about top-level functions, i.e. not locally-defined functions. In currently-released versions, it checks for top-level-ness of an identifier by the column position of its definition, which is rather a hack and pretty error-prone. From the next release, the top-level information will be generated correctly by the compiler itself. Regards, Malcolm
