New issue 2086 by [email protected]: Please allow building using Makefiles
and without Framework (iso Xcode) on Darwin
http://code.google.com/p/v8/issues/detail?id=2086
gyp's build generator defaults to xcode on Darwin, but can be overridden to
be set to make. However, if that's done, generation fails:
make -j8 V=1 GYP_GENERATORS=make library=shared werror=no
soname_version=3.9.24 snapshot=on x64.release
build/gyp/gyp --generator-output="out" build/all.gyp \
-Ibuild/standalone.gypi --depth=. -Dtarget_arch=x64 \
-S-x64 -Dcomponent=shared_library
-Dv8_can_use_vfp_instructions=true -Dsoname_version=3.9.24 -Dwerror=''

I applied some ugly sedding to force gyp into thinking it's building an
ordinary library (instead of a Framework) using a darwin flavour:
sed -i \
-e '/params\.get.*mac.*darwin.*linux/s/mac/darwin/' \
-e "/if GetFlavor(params) == 'mac':/s/mac/darwin/" \
-e "/^ if flavor == 'mac':/s/mac/darwin/" \
-e '/^LINK_COMMANDS_MAC =/,/^SHARED_HEADER =/s#-shared#-dynamiclib
-all_load#' \
build/gyp/pylib/gyp/generator/make.py || die
This allows me to build, which is just a mere proof that it is possible to
build without a Framework on Darwin. The changes hackishly 1) introduce a
darwin flavour, 2) set amongst other things OS to mac and SHARED_LIB_SUFFIX
to .dylib, 3) enable the use of gyp-mac-tool for darwin flavour (but avoid
setting up xcode settings), and 4) produce a non-empty v8.dylib (-all_load
forces including the unused members from the .a).
The LINK_COMMANDS_MAC should also include a -install_name
/path/to/v8.(version).dylib, but I don't know how to obtain the "/path/to"
part at that place. The $(@F) bit seems to be expand to ELF-style soname,
hence useless for Darwin. This probably requires hacking tools/gyp/v8.gyp
when it sets product_extension.
