[Libcdio-devel] Re: Recent libcdio breakage fixed I think. Please test.

Hi,

I have to confess that i did not further follow
the fate of the MMC_RDWR_EXCL tests.

That's mainly because libburn uses only a
few libcdio functions for drive enumeration,
drive aquiration, SCSI address retrieval,
and MMC command execution.


I brought my local libcdio copy to the newest
state.
Not easy. See requests at the end of this mail.

I made a completely new git clone into an
empty directory
  git clone git://git.sv.gnu.org/libcdio.git

The autotools requirement has changed from
  AM_INIT_AUTOMAKE([1.7])
to
  AM_INIT_AUTOMAKE([1.10])
and now i get from  ./autogen.sh
  Rebuilding ./configure with autoreconf...
  configure.ac:31: require Automake 1.10, but have 1.9.6
  autoreconf: automake failed with exit status: 1
  autoreconf: cannot empty /tmp/arx13039 (/tmp/arx13039/am4tX13698): Is a 
directory
  autoreconf failed

Is that demand for 1.10 really necessary ?
Well, i can try myself
  AM_INIT_AUTOMAKE([1.9])

... seems to work.
Up to
  make[3]: *** No rule to make target `cd-drive.1', needed by `all-am'.  Stop.
That is not a autotools problem but rather
a known obstacle with libcdio git clones.
Solvable by exploiting the release tarball
  cp ../../libcdio-0.82/src/*.1 src/

Then i bonk on
  mmc1.o: In function `main':
  .../example/mmc1.c:86: undefined reference to `mmc_get_disc_erasable'
The function exists in
  lib/driver/mmc/mmc.c 
But is not found by the linker.
I know this effect already :))
The function is not listed in
  lib/driver/libcdio.sym
The same with
  mmc_get_disctype

Ok, now it builds.


Where are the MMC_RDWR tests ?
(Will search after breakfast.)

Preliminary test of
  example/mmc1
runs.
One should issue better messages on empty tray,
though:
  Can't determine if disc is erasable.
  disc type: profile is The Logical Unit does not conform to any Profile 
(0xFFFF)

With media it seems ok, although i have problems
to make sense of the word "capable" here:

  Disc is erasable.
  disc type: profile is CD-RW Re-writable Compact Disc capable (0xA)


-----------------------------------------------

Change requests:

- Allow autotools 1.9, please.

  I cannot simply upgrade autotools on my
  workstation because the machine is owned by my
  employer. I may use it for own development but
  its system components may only be loaded from
  the SuSE DVDs.
  Regrettably, autotools was classified as system
  component, when we last adjusted the agreement.
  I simply don't know how to install it in a
  sandbox.

- Add the missing function names
    mmc_get_disc_erasable
    mmc_get_disctype
  to
    lib/driver/libcdio.sym

- Do something about the missing man page files
    src/*.1
  Shall they get generated ? From what ?
  Consider to generate them locally and to put
  them into git.


Have a nice day :)

Thomas
