Vim 7.3.94_0 to 7.3.102_0 +universal fails with symbols not found for i386

[wintesa@…]

Upgrading from 7.3.94_0 to 7.3.102_0 fails with:

...
:info:build Undefined symbols for architecture i386:
:info:build   "_rb_num2uint", referenced from:
:info:build       _window_set_cursor in if_ruby.o
:info:build ld: symbol(s) not found for architecture i386
:info:build collect2: ld returned 1 exit status
:info:build lipo: can't open input file: /var/tmp//ccm2NL6E.out (No such file or directory)
...

Seems to be fixed with:

file: src/if_ruby.c

1216 static VALUE window_set_cursor(VALUE self, VALUE pos) 1217 { 1218 VALUE lnum, col; 1219 win_T *win = get_win(self); 1220 1221 Check_Type(pos, T_ARRAY); 1222 if (RARRAY_LEN(pos) != 2) 1223 rb_raise(rb_eArgError, "array length must be 2"); 1224 lnum = RARRAY_PTR(pos)[0]; 1225 col = RARRAY_PTR(pos)[1]; 1226 win->w_cursor.lnum = NUM2LONG(lnum); 1227 win->w_cursor.col = NUM2LONG(col); /* Changed from NUM2UINT(col) 15/Feb/2011*/ 1228 check_cursor(); /* put cursor on an existing line */ 1229 update_screen(NOT_VALID); 1230 return Qnil; 1231 }

The problem is that the build for both architectures uses the x86_64 headers, although a separate set exists for i386 with differented defines. Ruby wants to be smart here and NUM2UINT is a no-op for sizeof(int) == sizeof(long) and, thus, no rb_num2uint function is compiled in this case.

From the vim73/src/auto/config.log:

RUBY_CFLAGS='-I/opt/local/lib/ruby/1.8/x86_64-darwin11 -DRUBY_VERSION=18'
RUBY_LIBS='-lruby -lpthread -ldl -lobjc  -L/opt/local/lib'

I am not yet sure if this is a more general bug in ruby +universal or if it should be fixed in the vim build only.

Is this still a problem with the current version?

Assuming there is nothing to do here anymore.
