Rebecca,

I don’t think `-z` is a valid argument to ld64 (macOS linker). My guess is XCODE is inheriting a GCC flag from a platform DSC file. 

$ git grep "z common-page-size" -- *.dsc
OvmfPkg/OvmfPkgIa32.dsc:89:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfPkgIa32.dsc:97:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfPkgIa32X64.dsc:93:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfPkgIa32X64.dsc:101:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfPkgX64.dsc:93:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfPkgX64.dsc:101:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfXen.dsc:84:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
OvmfPkg/OvmfXen.dsc:92:  GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
StandaloneMmPkg/StandaloneMmPkg.dsc:116:GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000 -march=armv8-a+nofp -mstrict-align

Thanks,

If it works, can you please also do a review?  Many community members are offline this week and I want to get these fixes in.

Subject: [edk2-devel] Error building OVMF on x86 macOS with Xcode 12.5

I'm trying to build OVMF on an x86 Mac running Big Sur and Xcode 12.5.

If I run "./OvmfPkg/build.sh -a X64 -t XCODE5 -b RELEASE" it seems to
get quite far, but then tries to run ld with "-z common-page-size",
causing the error:


"ld" -arch x86_64 -u __ModuleEntryPoint -e __ModuleEntryPoint -preload
-segalign 0x20 -pie -all_load -dead_strip -seg1addr 0x240 -map
