I confirm that on amd64, building magic with the latest GHC (v8.0.1-4) fails with the following error: | # cabal install magic | Resolving dependencies... | Downloading magic-1.1... | Configuring magic-1.1... | Building magic-1.1... | Failed to install magic-1.1 | Build log ( /root/.cabal/logs/magic-1.1.log ): | cabal: Entering directory '/tmp/cabal-tmp-17350/magic-1.1' | Configuring magic-1.1... | Building magic-1.1... | Preprocessing library magic-1.1... | /usr/bin/ld: dist/build/Magic/Data_hsc_make.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC | /usr/bin/ld: final link failed: Nonrepresentable section on output | collect2: error: ld returned 1 exit status | linking dist/build/Magic/Data_hsc_make.o failed (exit code 1) | command was: /usr/bin/gcc dist/build/Magic/Data_hsc_make.o dist/build/Magic/Data_hsc_utils.o -o dist/build/Magic/Data_hsc_make -fno-PIE -fno-stack-protector -lmagic -L/usr/lib/ghc/base-4.9.0.0 -Wl,-R,/usr/lib/ghc/base-4.9.0.0 -L/usr/lib/ghc/integer-gmp-1.0.0.1 -Wl,-R,/usr/lib/ghc/integer-gmp-1.0.0.1 -lgmp -L/usr/lib/ghc/ghc-prim-0.5.0.0 -Wl,-R,/usr/lib/ghc/ghc-prim-0.5.0.0 -L/usr/lib/ghc/rts -Wl,-R,/usr/lib/ghc/rts -lm -lrt -ldl -lffi If I downgrade gcc-6 to a version prior to v6.2.0-7, it works! It also works with GHC v7.10.3-10. Today I noticed a similar bug on grads [#841493]. Could it be that libmagic.a has not been built with -fPIC? [#841493] https://bugs.debian.org/841493 -- Ilias
