Bug#838198: 9base: FTBFS on hurd-i386: fatal error:can't create y.tab.h, :1

[Ola Ekström]

I missed that one, can't say I understand it's purpose in the source
tree if it's not referenced. I'm not familiar with sam or 9P, I've
only used 9base to run the werc web framework on lighttpd.

[Kalle Olavi Niemitalo]

sam/_libc.h has:

OREAD = 0,
OWRITE = 1,
ORDWR = 2,
OCEXEC = 4,

but it looks like nothing #includes that file, so perhaps that
doesn't have to be patched.  Have you tested sam on the Hurd?

If these flags are sent in the Topen and Tcreate requests of the
9P protocol, then changing their values breaks compatibility
between network hosts that run different implementations.
Do the Debian packages support that protocol?

Package: 9base
Severity: important
Version: 1:6-7
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd
X-Debbugs-CC: debian-h...@lists.debian.org

The package fails to build on hurd-i386 because of incorrect values
supplied to fopen() and missing (__GNU__)-defines.

Failing build log:
https://buildd.debian.org/status/package.php?p=9base=sid

The supplied patch fixes this.

TODO: Write a Hurd-specific disksize()-function in lib9/_p9dir.c

Cheers,
Ola Ekström
