Re: [cctbxbb] Problems compiling cctbx on OS X (10.8.0)

As Graeme mentioned you currently need to use --compiler=gcc to force compilation with gcc over clang for the latest Xcode/OS X (we should probably try and figure out how to the configure command use gcc by default). The cctbx *should* build with the more recent versions of clang (perhaps Luc could comment on this as I think he uses clang regularly), although depending on what version of Xcode you are using, Apple used to ship a relatively old version of clang/llvm with Xcode, so clang compilation might not necessarily work straight out the box. What output do you get after running "clang --version"? After upgrading to OS X 10.8/Xcode 4.4 I get: Apple clang version 4.0 (tags/Apple/clang-421.0.57) (based on LLVM 3.1svn) which is more recent than with older versions of Xcode. We should probably add a clang build to our nightly builds at some point in the near future. Cheers, Richard On 1 August 2012 10:13, Marcin Wojdyr wrote:

Out of curiosity: i remember reading somewhere that cctbx can be compiled with clang (and that it took a lot of work). Do you plan to support this compiler? Marcin

Apple has been "messing around" with the Xcode and the OS to prefer CLang over gcc (at least that is what I have inferred). It could be that on Mac OS X 10.8 that scons chooses a different compiler, etc. than on Mac OS X 10.6.8 (where cctbx compiles fine).

Hopefully scons has a method to print the toolchain or config to see what differs from previous versions of Mac OS X (e.g. 10.6.8 and 10.8.0) Xcode 3.* or Xcode 4.*?
