File loadpath.c includes verconf.h where (on a normal build) all the missing tokens are defined.

A suitable verconf.h should be created on buildtime just before compiling loadpath.c, see log
of a normal build:

gcc version 4.8.3 (Buildroot 2015.02-git-00219-gc5f0e93)
config.status: creating arm-linux-gnueabi-fake.rb
rbconfig.rb updated
generating enc.mk
compiling dln.c
compiling localeinit.c
creating verconf.h
compiling loadpath.c
copying dummy probes.h


The line 'creating verconf.h' is missing from the log of the failed build.

While the configure step an empty verconf.h file is genereated by the the following code
from configure.in (linbe 3764):

3746 AC_ARG_WITH(ruby-version,
3747             AS_HELP_STRING([--with-ruby-version=STR], [ruby version string for version specific directories [[full]] (full|minor|STR)]),
3748             [ruby_version=$withval],
3749             [ruby_version=full])
3750 unset RUBY_LIB_VERSION
3751 unset RUBY_LIB_VERSION_STYLE
3752 AS_CASE(["$ruby_version"],
3753   [full],  [RUBY_LIB_VERSION_STYLE='3   /* full */'],
3754   [minor], [RUBY_LIB_VERSION_STYLE='2   /* minor */'])
3755 if test ${RUBY_LIB_VERSION_STYLE+set}; then
3756     {
3757     echo "#define RUBY_LIB_VERSION_STYLE $RUBY_LIB_VERSION_STYLE"
3758     echo '#define STRINGIZE(x) x'
3759     test -f revision.h -o -f "${srcdir}/revision.h" || echo '#define RUBY_REVISION 0'
3760     echo '#include "verconf.h"'
3761     echo '#include "version.h"'
3762     echo 'ruby_version=RUBY_LIB_VERSION'
3763     } > conftest.c
3764     test -f verconf.h || > verconf.h
3765     ruby_version="`$CPP -I. -I"${srcdir}" -I"${srcdir}/include" conftest.c | sed '/^ruby_version=/!d;s/ //g'`"
3766     eval $ruby_version
3767 elif test -z "${ruby_version}"; then
3768     AC_MSG_ERROR([No ruby version, No place for bundled libraries])
3769 else
3770     RUBY_LIB_VERSION="\"${ruby_version}\""
3771 fi
3772 AC_SUBST(RUBY_LIB_VERSION_STYLE)
3773 AC_SUBST(RUBY_LIB_VERSION)


>From common.mk:

 774 loadpath.$(OBJEXT): {$(VPATH)}loadpath.c $(RUBY_H_INCLUDES) \
 775   $(srcdir)/include/ruby/version.h $(srcdir)/version.h {$(VPATH)}config.h \
 776   verconf.h

loadpath.o depends on verconf.h, should be generated by:

 846 verconf.h: $(srcdir)/template/verconf.h.in $(srcdir)/tool/generic_erb.rb $(RBCONFIG)
 847         $(ECHO) creating $@
 848         $(Q) $(MINIRUBY) "$(srcdir)/tool/generic_erb.rb" $(srcdir)/template/verconf.h.in > $@

which depends on $(RBCONFIG), defined as '.rbconfig.time' in Makefile:17, which should be generated by:

 542 $(RBCONFIG): $(srcdir)/tool/mkconfig.rb config.status $(srcdir)/version.h $(PREP)
 543         $(Q)$(MINIRUBY) $(srcdir)/tool/mkconfig.rb -timestamp=$@ \
 544                 -install_name=$(RUBY_INSTALL_NAME) \
 545                 -so_name=$(RUBY_SO_NAME) rbconfig.rb


Something in this chain of dependencies seems to fail (timestamp problems?, race condition?)....

Maybe deleting the configure created empty version of the verconf.h file works?

The only two files including verconf.h are:

 loadpath.c:12:#include "verconf.h"
 nacl/pepper_main.c:29:#include "verconf.h"

Peter
