nhc98 1.14a build fails on Linux
by Peter Simons 06 Jan '03

06 Jan '03

Hi, I just tried to build the latest nhc98 version on Gentoo Linux/ix86. And failed. ;-) The build was initiated with $ ./configue --prefix=/usr/local/nhc98 +docs $ make and it got this far: (Line-wrapping is mine.) make[1]: Entering directory `/usr/local/src/nhc98-1.14a/src/prelude/ix86-Linux' rm -f *.hi rm -f DErrNo.hc rm -f /usr/local/src/nhc98-1.14a/targets/ix86-Linux/obj/prelude/DErrNo/*.o *.o rm -f rm -f /usr/local/src/nhc98-1.14a/script/nhc98 -cpp -c +CTS -lib -redefine -CTS +RTS -H32M -RTS -o /usr/local/src/nhc98-1.14a/targets/ix86-Linux/obj/prelude/DErrNo/DErrNo.o DErrNo.hs /usr/local/src/nhc98-1.14a/script/nhc98: line 600: 32003 Segmentation fault $COMP $RUNFLAGS $COMPFLAGS $HINCDIRS $UNLIT -P${NHC98INCDIR} $HSFILE $POSTGRFILE $TMPHIFILE $TMPCPPASFILE make[1]: *** [/usr/local/src/nhc98-1.14a/targets/ix86-Linux/obj/prelude/DErrNo/DErrNo.o] Error 1 make[1]: Leaving directory `/usr/local/src/nhc98-1.14a/src/prelude/ix86-Linux' make: *** [targets/ix86-Linux/compiler-gcc] Error 2 I am quite lost what to do and what to try. Does anyone have an idea? One more thing: Is it possible that the build is screwed up pretty much in case I do have a version of hmake installed already? (I do, and hmake has been compiled with ghc support only, so far. I had to take it out of the PATH to make the build get this far at all.) -peter

How to make System Calls in NHC98?
by Alberto 02 Jan '03

02 Jan '03

Hi :) , I am creating a tiny app in Haskell to search for a directory in the tree and change the current shell directory just to learn to program better in Haskell and I've always used the Win/Hugs98 interpreter but I've just moved to FreeBSD/NHC98 because I want binary code and the thing is I can't find a function in NHC98 to make a pipe to comunicate with the shell (csh in my case) and that's the question: are the FreeBSD pipes functionality available in NHC98? By the way, can one make arbitrary System Calls in NHC98 by any means? if no, how can I change the shell's current directory? Regards, Alberto Dominguez (Spain)

Problems building hmake
by Bryn Keller 02 Jan '03

02 Jan '03

Hi folks, I'm trying to build hmake, so I can build HaXml. I'm running a Windows 2000 system with the latest Cygwin (as of this morning) and GHC-5.04.2. I'm having some trouble with the cygwin path that's passed to GHC during the build process: $ make cd src/hmake; make HC=ghc install config make[1]: Entering directory `/temp/hmake-3.06/src/hmake' ghc -package lang -c -o /cygdrive/c/temp/hmake-3.06/targets/ix86-CYGWIN_NT-5.0/obj/hmake/QSort.o QSort.hs d:\ghc\ghc-5.04.2\bin\ghc.exe: error: directory portion of "/cygdrive/c/temp/hmake-3.06/targets/ix86-CYGWIN_NT-5.0/obj/hmake/QSort.o" does not exist (used with "-o" option.) make[1]: *** [/cygdrive/c/temp/hmake-3.06/targets/ix86-CYGWIN_NT-5.0/obj/hmake/Q Sort.o] Error 1 make[1]: Leaving directory `/temp/hmake-3.06/src/hmake' make: *** [targets/ix86-CYGWIN_NT-5.0/hmake-ghc] Error 2 I did find this bit of advice (linked from the NHC page, not the hmake page, btw): The build system for nhc98 uses an absolute pathname as the destination of a compile command. This is one of the areas where Cygwin and GHC can conflict if you are not careful. The important thing to remember is that the location in which you unpack the nhc98 distribution must have the same absolute filepath in both Cygwin and Windows. For instance, a Cygwin mount that maps C:\tmp to /tmp will work fine, whereas a mount that maps C:\cygwin\tmp to /tmp will probably not work. So I did this: mount c:\\temp /temp cd /temp make clean ./configure and edited the path (BUILDDIR) in config.cache to reflect this new situation. However, the path that it's passing to GHC is still the old /cygdrive path. How should I correct this? Thanks in advance, Bryn
