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, Andrew Fish > On May 2, 2021, at 12:06 PM, Rebecca Cran wrote: > > It doesn't seem to apply against > 1e6b0394d6c001802dc454ecff19076aaa80f51c (master as of today): > > patching file BaseTools/Source/Python/AutoGen/ModuleAutoGenHelper.py > Hunk #1 FAILED at 181. > Hunk #2 FAILED at 632. > 2 out of 2 hunks FAILED -- saving rejects to file > BaseTools/Source/Python/AutoGen/ModuleAutoGenHelper.py.rej > patching file BaseTools/Source/Python/AutoGen/PlatformAutoGen.py > Hunk #1 FAILED at 1391. > Hunk #2 FAILED at 1534. > 2 out of 2 hunks FAILED -- saving rejects to file > BaseTools/Source/Python/AutoGen/PlatformAutoGen.py.rej > patching file BaseTools/Source/Python/build/build.py > Hunk #1 FAILED at 897. > Hunk #2 FAILED at 930. > 2 out of 2 hunks FAILED -- saving rejects to file > BaseTools/Source/Python/build/build.py.rej > > -- > Rebecca Cran > > On 5/2/21 12:04 PM, Kinney, Michael D wrote: >> Please try this patch: >> >> https://edk2.groups.io/g/devel/message/74684 >> >> If it works, can you please also do a review?
