I tried ghc-4.08.2-1.i386.rpm (both the RH-6 rpm and the RH-7 rpm) on my Linux box running RH rawhide-2001-02-06 (a touch newer than the RH-7.0.90 beta release Fisher), which both use glibc-2.2.1. When I compile a program, eg a test program like "test.hs": module Main (main) where main = putStrLn "Hello!" I get a put linking errors: ---- Start of included text -----------------------8<--- cut here ------------- % ghc test.hs /usr/lib/ghc-4.08.2/libHSrts.a(Storage.o): In function `initStorage': Storage.o(.text+0x2c2): undefined reference to `mp_set_memory_functions' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `addr2Integerzh_fast': PrimOps.o(.text+0x4a6): undefined reference to `mpz_init_set_str' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `plusIntegerzh_fast': PrimOps.o(.text+0x6fa): undefined reference to `mpz_init' PrimOps.o(.text+0x710): undefined reference to `mpz_add' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `minusIntegerzh_fast': PrimOps.o(.text+0x78e): undefined reference to `mpz_init' PrimOps.o(.text+0x7a4): undefined reference to `mpz_sub' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `timesIntegerzh_fast': PrimOps.o(.text+0x822): undefined reference to `mpz_init' PrimOps.o(.text+0x838): undefined reference to `mpz_mul' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `gcdIntegerzh_fast': PrimOps.o(.text+0x8b6): undefined reference to `mpz_init' PrimOps.o(.text+0x8cc): undefined reference to `mpz_gcd' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `quotIntegerzh_fast': PrimOps.o(.text+0x94a): undefined reference to `mpz_init' PrimOps.o(.text+0x960): undefined reference to `mpz_tdiv_q' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `remIntegerzh_fast': PrimOps.o(.text+0x9de): undefined reference to `mpz_init' PrimOps.o(.text+0x9f4): undefined reference to `mpz_tdiv_r' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `divExactIntegerzh_fast': PrimOps.o(.text+0xa72): undefined reference to `mpz_init' PrimOps.o(.text+0xa88): undefined reference to `mpz_divexact' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `quotRemIntegerzh_fast': PrimOps.o(.text+0xb06): undefined reference to `mpz_init' PrimOps.o(.text+0xb15): undefined reference to `mpz_init' PrimOps.o(.text+0xb2f): undefined reference to `mpz_tdiv_qr' /usr/lib/ghc-4.08.2/libHSrts.a(PrimOps.o): In function `divModIntegerzh_fast': PrimOps.o(.text+0xbbe): undefined reference to `mpz_init' PrimOps.o(.text+0xbcd): undefined reference to `mpz_init' PrimOps.o(.text+0xbe7): undefined reference to `mpz_fdiv_qr' collect2: ld returned 1 exit status ---- End of included text -------------------------8<--- and here ------------- I think these are related to gmp2. (BTW are there plans to upgrade to gmp3, which seems to be standard now in the Linux world?) I can compile ok with nhc98 (from "nhc98-1.02-1.i386.rpm"). Any ideas why the ghc rpms aren't working for me? Best wishes, Jens
