Re: [Libguestfs] trouble compiling libguestfs 1.17.21



here is the two results I got from three commands:

$ grep for_each src/libguestfs.syms       
    guestfs___for_each_disk;

$ nm -D src/.libs/libguestfs.so | grep for_each
    no result returned

It builds OK for me here, which is not to say that it's not a bug (it
certainly looks like one) just that I cannot reproduce it.

If the symbol exported from the library?  On my F16 machine, the
symbol is added correctly to the export script:

  $ grep for_each src/libguestfs.syms
          guestfs___for_each_disk;

and exported correctly from the library:

  $ nm -D src/.libs/libguestfs.so | grep for_each
  00000000000704b0 T guestfs___for_each_disk

You could also try looking at the link command:

  make -C df V=1

Rich.

PS.
I do see another, completely unrelated bug:

  make[3]: Leaving directory `/home/rich/d/libguestfs-1.17.21/generator'
  rake build
  rake aborted!
  no such file to load -- rdoc/task
 
  (See full trace by running task with --trace)

which appears to caused by fd7a5a8bbdc69b9d2a92f6d05ac555334d0516bf.
