#42864: ocaml @4.01.0 build failure with Xcode 5.1 --------------------+-------------------------------- Reporter: ats@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Keywords: | Port: ocaml --------------------+-------------------------------- The ocaml port fails to build with Xcode 5.1. It fails as follows: {{{ :info:build /usr/bin/clang -DCAML_NAME_SPACE -O -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -o interp.o interp.c :info:build clang: error: unknown argument: '-fno-defer-pop' [-Wunused- command-line-argument-hard-error-in-future] :info:build clang: note: this will be a hard error (cannot be downgraded to a warning) in the future }}} It appears that clang in Xcode 5.1 will treat unknown arguments as an error. This can be worked around by setting -Wno-error=unused-command- line-argument-hard-error-in-future or removing the unknown argument. Here are a couple links I found which discuss this issue: * https://twistedmatrix.com/trac/ticket/6974 * http://stackoverflow.com/questions/22394575/xcode-llvm-5-1-clang-error {{{ Version Information for: /Applications/Xcode.app CFBundleShortVersionString 5.1 CFBundleVersion 5084 Hardware Information: Model Name: MacBook Air Model Identifier: MacBookAir5,2 Processor Name: Intel Core i7 Processor Speed: 2 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache (per Core): 256 KB L3 Cache: 4 MB Memory: 8 GB Operating System Information: ProductName: Mac OS X OS X Version: 10.9.3 BuildVersion: 13D17 }}} -- Ticket URL: <https://trac.macports.org/ticket/42864> MacPorts <http://www.macports.org/> Ports system for OS X
