mxcl/homebrew Issue #899: readline should build a ‘universal’ binary

Linked on Nov 26 at 21:55

If you ever get an error message of “configure: error: C compiler cannot create executables” when executing brew install readline, then do what’s suggested in a related Homebrew issue:

  1. brew edit readline
  2. Comment out the line which starts with ENV.universal_binary.
  3. Re-execute your previous brew install command.

The above also applies to the following packages:

Apparently the configuration specifying a Universal or PowerPC build target for libraries is in the library itself, not passed to it. If the library author wants to stop people using it on PowerPC, he/she can.
