[Buildroot] Problems building nbd.

[Buildroot] Problems building nbd.

[Thiago A. Corrêa]

Hi,

   It seams that newer nbd (Allows mounting block devices from the
network) needs glib to compile, as confirmed by a post from a at their
own mailing list
(http://sourceforge.net/mailarchive/message.php?msg_id=20070817120341.GA12011%40country.grep.be)

   So, I tried adding glib support to buildroot, but there seams to be
some obstacles on the way:

  First, it fails configure. The package seams to try to detect some
unusual things about the target system, such as stack grow direction.
One can provide configure with a variable that will make it pass, but
then again, the value of this variable might be system dependent.
Thus, I'm not sure how to proceed. It seams that an AVR32 value would
be  glib_cv_stack_grows=no but I don't know if it holds true for all
buildroot supported platforms.

  Googling about the problem, I found that OpenEmbedded has platform
specific files with such variables set. AFAIK we don't have such
feature.

  The other option to fix nbd would be to downgrade to something below
2.8, but then we would still be unable to support the next package
that requires glib.

  Any thoughts?

  I'm appending my glibc.mk for reference at the end.

Kind Regards,
   Thiago A. Correa

We DO have glib packages in buildroot (1.2.x and 2.x.x) -
package/libglib12 and package/libglib2.

Ops, I missed that :(

I've added the dependency to nbd.mk and it seams to be working fine now.

Anyway, is that a valid concern (skipping configure tests which
results might be platform dependent?) or perhaps that's not worth to
worry about? I see that the libglib2.mk does set the same variables
that I mentioned earlier.
