I apologize if this is the wrong mailing list, however I couldn't find another one that seemed fit. On the official binary release page (https://www.haskell.org/ghc/download_ghc_8_10_1.html) under the x86_64 alpine release it states the following:
Unlike our other binary distributions, this links against the`integer-simple`big-integer backend and therefore does not require`libgmp`.
However, ldd shows that it DOES link to gmp: libgmp.so.10 => /lib/libgmp.so.10 (0x7f47f4c94000) Additionally, if gmp is not installed then a number of errors appear: Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_tdiv_qr: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_gcd_1: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_add_1: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_andn_n: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpz_gcdext: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_lshift: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_rshift: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_and_n: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpz_powm: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_mod_1: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_cmp: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_add: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_sub_1: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpn_xor_n: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpz_clear: symbol not found Error relocating /usr/bin/../lib/x86_64-linux-ghc-8.10.1/libHSinteger-gmp-1.0.3.0-ghc8.10.1.so: __gmpz_invert: symbol not found Either this build isn't configured properly or the text on the release page needs to be edited to reflect this.
