[patch] cabal-1.24.2.0-llvm-ar.patch

cabal-1.24.2.0-llvm-ar.patch (text/plain), 1.02 KB, created by Sergei Trofimovich (RETIRED) on 2017-05-22 08:24:25 UTC

'$ cabal build --with-ar=llvm-ar -v' calls llvm-ar in
an unsupported for llvm way:

  /usr/bin/llvm-ar -r dist/build/<foo>.a dist/build/<bar>.o
  llvm-ar: Unknown command line argument '-r'.  Try: '/usr/bin/llvm-ar -help'
  llvm-ar: Did you mean '-M'?

The correct call would be 'llvm-ar r'.
