sto creando llvm/clang 3.7 con supporto bitcode (-fembed-bitcode). Alcuni moduli non possono essere collegati a causa dell'errore:ld: -bundle e -bitcode_bundle non possono essere utilizzati insieme
ld: -bundle and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together clang: error: linker command failed with exit code 1 (use -v to see invocation)
uscita di errore completa:

Sembra che -bundle è aggiunti dai CMake come non ero in grado di trovare in CMakeLists.txt e -bitcode_bundle viene aggiunto da SDK a causa di -fembed-bitcode.
Come posso risolvere il problema? Qualche soluzione alternativa (ad esempio per disattivare la costruzione di dylibs poiché non ne ho bisogno)?
Consiglierei di chiedere agli utenti di clang mailing list: http://lists.llvm.org/mailman/listinfo/cfe-users – AlexDenisov
