Hi, recently I've upgraded my RedHat box from 8 to 9. This immediately gave rise to a lot of problem due to incompatibility (I guess). When I try to compile my haskell library, for example (HaXml), it halted with this error message /usr/local/lib/ghc-5.02.3/libHSrts.a(RtsFlags.o)(.text+0x1b0): In function `setupRtsFlags': : undefined reference to `__ctype_b' collect2: ld returned 1 exit status I then try to recompile my ghc from source, the compilation terminates with the same error. for which I thought it is due to update on static links from glibc version 2.2 to 2.3. But I think this has already been fixed by some previous version. This problem is resolved until I reverted my glibc package back to 2.3.2-4.80 Any of you have ever encoutered the same issue?
