I am also facing the same issue. Details are : v8: tag/8.5.188 macOS: Big Sur 11.3.1
the original error "../../include/cppgc/allocation.h:168:39: error: no member named 'forward' in namespace 'std'" is resolved by switching to this v8 version "tag/8.5.188" but I am still getting the following error in this version : ============================================================= ➜ v8 git:(heads/tags/8.5.188) ✗ ninja -C out/release-ios ninja: Entering directory `out/release-ios' [0/1] Regenerating ninja files [1/3397] CXX obj/cppgc_base/marking-worklists.o FAILED: obj/cppgc_base/marking-worklists.o ../../../../../../../../Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -MMD -MF obj/cppgc_base/marking-worklists.o.d -DCR_XCODE_VERSION=1251 -DCR_CLANG_REVISION=\"llvmorg-14-init-591-g7d9d926a-1\" -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D_FORTIFY_SOURCE=2 -DNDEBUG -DNVALGRIND -DDYNAMIC_ANNOTATIONS_ENABLED=0 -DNS_BLOCK_ASSERTIONS=1 -DV8_TYPED_ARRAY_MAX_SIZE_IN_HEAP=64 -DENABLE_MINOR_MC -DENABLE_HANDLE_ZAPPING -DV8_ATOMIC_OBJECT_FIELD_WRITES -DV8_ATOMIC_MARKING_STATE -DV8_ENABLE_LAZY_SOURCE_POSITIONS -DV8_SHARED_RO_HEAP -DV8_WIN64_UNWINDING_INFO -DV8_ENABLE_REGEXP_INTERPRETER_THREADED_DISPATCH -DV8_SNAPSHOT_COMPRESSION -DV8_ENABLE_WEBASSEMBLY -DV8_ALLOCATION_FOLDING -DV8_ALLOCATION_SITE_TRACKING -DV8_ADVANCED_BIGINT_ALGORITHMS -DV8_DEPRECATION_WARNINGS -DV8_IMMINENT_DEPRECATION_WARNINGS -DCPPGC_CAGED_HEAP -DV8_TARGET_ARCH_ARM64 -DV8_HAVE_TARGET_OS -DV8_TARGET_OS_IOS -DV8_RUNTIME_CALL_STATS -DDISABLE_UNTRUSTED_CODE_MITIGATIONS -I../.. -Igen -I../../include -Igen/include -fno-delete-null-pointer-checks -fno-ident -fno-strict-aliasing --param=ssp-buffer-size=4 -fstack-protector -fcolor-diagnostics -fmerge-all-constants -target arm64-apple-ios10 -Wno-builtin-macro-redefined -D__DATE__= -D__TIME__= -D__TIMESTAMP__= -ffile-compilation-dir=. -no-canonical-prefixes -Wall -Wextra -Wimplicit-fallthrough -Wunreachable-code -Wthread-safety -Wextra-semi -Wunguarded-availability -Wundeclared-selector -Wno-missing-field-initializers -Wno-unused-parameter -Wloop-analysis -Wno-unneeded-internal-declaration -fno-omit-frame-pointer -g2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.5.sdk -fembed-bitcode -Wheader-hygiene -Wstring-conversion -Wtautological-overlap-compare -Wmissing-field-initializers -Wunreachable-code -Wshorten-64-to-32 -O3 -fvisibility=default -Wexit-time-destructors -std=c++14 -fno-trigraphs -Wno-trigraphs -fno-exceptions -fno-rtti -c ../../src/heap/cppgc/marking-worklists.cc -o obj/cppgc_base/marking-worklists.o clang++: error: unknown argument: '-ffile-compilation-dir=.'
