ld issue for ppc compiler #27

Closed siriuscn closed 8 years ago

siriuscn commented 8 years ago

Could not compiler the ppc target with these components.

Steps:

  1. Make a fresh project with Xcode 7.3.1. 2.Set the Base SDK to Mac OS X 10.5 3.Set the Compiler to GCC 4.2 4.Set the Deploy target to OS X 10.5 5.Compiler

Result:

Ld DerivedData/test/Build/Products/Debug/test.app/Contents/MacOS/test normal ppc cd /Users/xxx/Desktop/test export MACOSX_DEPLOYMENT_TARGET=10.5 /Applications/Xcode.app/Contents/Developer/usr/bin/gcc-4.0 -arch ppc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.5.sdk -L/Users/xxx/Desktop/test/DerivedData/test/Build/Products/Debug -F/Users/xxx/Desktop/test/DerivedData/test/Build/Products/Debug -filelist /Users/xxx/Desktop/test/DerivedData/test/Build/Intermediates/test.build/Debug/test.build/Objects-normal/ppc/test.LinkFileList -Xlinker -rpath -Xlinker @executable_path/../Frameworks -mmacosx-version-min=10.5 -Xlinker -no_deduplicate -fobjc-link-runtime -framework Cocoa -Xlinker -dependency_info -Xlinker /Users/xxx/Desktop/test/DerivedData/test/Build/Intermediates/test.build/Debug/test.build/Objects-normal/ppc/test_dependency_info.dat -o /Users/xxx/Desktop/test/DerivedData/test/Build/Products/Debug/test.app/Contents/MacOS/test

That's an Xcode 7.3 issue. There does not seem to be any way to disable this flag. You could copy-paste the command-line to a terminal and remove the flags "-Xlinker -no_deduplicate". Or you could use another build system than Xcode (Makefile, cmake, qmake...).

I fixed the compiler issue. Add a User-Defined build setting LD_DONT_RUN_DEDUPLICATION and set its value to NO.

Everything goes right.:)

xcodelegacy now installs a ld stub which filters the unsupported arguments, so it should rune fine out of the box. see: https://github.com/devernay/xcodelegacy/blob/master/XcodeLegacy.sh#L746
