[ruby-core:56324] [Backport 200 - Backport #7948] Can not compile pseudo static Ruby binary on OSX

Issue #7948 has been updated by mpapis (Michal Papis).


=begin
confirming that for static extensions ((({--with-static-linked-ext}))) it is required to ignore extensions that fail, for me on OSX it was:

 --with-out-ext=dl/win32,fiddle/win32,tk/tkutil,win32ole,-test-/win32/dln,-test-/win32/fd_setsize

which makes the static ruby compilation two step pass process:

 make | grep "^Failed to configure"
 ./configure --with-out-ext=...,...,...
 make

this is related to the change http://www.rubyist.net/~eban/goto/r42213 - can we make the "Fail"s to be ignored from static compilation list?

Backport #7948: Can not compile pseudo static Ruby binary on OSX

In ruby 1.9.x I was using `LDFLAGS="-Bstatic $LDFLAGS"` to force pseudo static compilation on OSX (full static is not possible).

This stopped to work with 2.0.0-p0, the binary is compiled but the static flag is not handled properly and the generated binary can not run:

$ ~/.sm/pkg/versions/tokaidoapp/2.0.0-p0/bin/ruby --version
dyld: Symbol not found: _Init_encinit
  Referenced from: /Users/mpapis/.sm/pkg/versions/tokaidoapp/2.0.0-p0/bin/ruby
  Expected in: flat namespace
 in /Users/mpapis/.sm/pkg/versions/tokaidoapp/2.0.0-p0/bin/ruby
Trace/BPT trap

using `otool -L ~/.sm/pkg/versions/tokaidoapp/2.0.0-p0/bin/ruby` I can see the binary depends on a lot more external libraries:

/Users/mpapis/.sm/pkg/versions/tokaidoapp/2.0.0-p0/bin/ruby:
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
	/Users/mpapis/.sm/pkg/versions/openssl/0.9.8y/lib/libssl.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
	/Users/mpapis/.sm/pkg/versions/openssl/0.9.8y/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
	/usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0)
	/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk (compatibility version 8.5.0, current version 8.5.7)
	/System/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl (compatibility version 8.5.0, current version 8.5.7)
	/usr/lib/libffi.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libutil.dylib (compatibility version 1.0.0, current version 1.0.0)

compared to `otool -L ~/.sm/pkg/versions/tokaidoapp/1.9.3-p392/bin/ruby`

/Users/mpapis/.sm/pkg/versions/tokaidoapp/1.9.3-p392/bin/ruby:
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)

What is the preferred way to compile static ruby (with minimal external dependencies) on systems like OSX which do not provide default package manager so no default library paths can be assumed.
