| 37 | | == A port build fails on Snow Leopard with: "file is not of required architecture" == #wrongarch |

| 39 | | If you had MacPorts installed before upgrading to Snow Leopard, see [wiki:Migration]. |

| 41 | | == A port fails to build when using Xcode 4/5 == #compiler |
| 42 | | |
| 43 | | gcc has been the compiler collection MacPorts has used by default up until Xcode 4, in which Apple has switched to the llvm/clang compiler collection. These are new compilers and many programs have not yet been tested with them, and some ports will fail as a result. Using a different compiler may work better for a particular port. If the below workarounds enable you to install a port that failed with its default compiler, file a ticket and let us know so we can fix it. Portfile authors, see wiki:PortfileRecipes#compiler. |

| 45 | | === Xcode 4.2 and later (including Xcode 5) === #xcode42 |
| 46 | | |
| 47 | | If a port ''foo'' fails to build and you're using Xcode 4.2 or later, the default compiler is clang; try compiling with llvm-gcc-4.2 instead: |
| 48 | | |
| 49 | | {{{ |
| 50 | | sudo port clean foo |
| 51 | | sudo port install foo configure.compiler=llvm-gcc-4.2 |
| 52 | | }}} |
| 53 | | |
| 54 | | If that fails, try installing the apple-gcc42 port and compiling with that: |
| 55 | | |
| 56 | | {{{ |
| 57 | | sudo port clean foo |
| 58 | | sudo port install apple-gcc42 |
| 59 | | sudo port install foo configure.compiler=apple-gcc-4.2 |
| 60 | | }}} |
| 61 | | |
| 62 | | === Xcode 4.0 and 4.1 === #xcode40 |
| 63 | | |
| 64 | | If a port ''foo'' fails to build and you're using Xcode 4.0 or 4.1, the default compiler is llvm-gcc-4.2; try compiling with clang instead: |
| 65 | | |
| 66 | | {{{ |
| 67 | | sudo port clean foo |
| 68 | | sudo port install foo configure.compiler=clang |
| 69 | | }}} |
| 70 | | |
| 71 | | If that fails, try using gcc-4.2: |
| 72 | | |
| 73 | | {{{ |
| 74 | | sudo port clean foo |
| 75 | | sudo port install foo configure.compiler=gcc-4.2 |
| 76 | | }}} |
