[Buildroot] nbd fails to compile with /usr/bin/klcc: unknown option: --sysroot=

[Buildroot] nbd fails to compile with /usr/bin/klcc: unknown option: --sysroot=

[Peter Hüwe]

Hi,

the atngw100_defconfig has nbd client and server enabled, and unfortunately it fails to compile, with the message

/usr/bin/klcc: unknown option: --sysroot=/avr/buildroot/output/staging/

$klcc --version
x86_64-pc-linux-gnu-gcc (GCC) 4.1.2 (Gentoo 4.1.2 p1.3)

How can I fix this ? - Unfortunately I'm not that into the whole buildroot system (yet, but I'd like to learn and contribute to it).

Thanks,
Peter

It's because you have klcc installed on your development system, nbd
detects it and uses it. Unfortunately, it doesn't understand all the
usual gcc options.

You have two options to solve this problem:

 *) Pass the --disable-klcc option to NBD's configure script. You could
    add this to NBD_CONF_OPT.

 *) Update to nbd 2.9.15 (the current version in Buildroot is 2.9.11),
    which has removed support for klcc.

In any case, don't forget to send a patch ! :-)

[Buildroot] [PATCH] nbd: Bump nbd to version 2.9.15 and remove klcc issue.

[Peter Huewe]

From: Peter Huewe <peterhuewe@gmx.de>

This patch bumps the version of nbd to 2.9.15.
The new version avoids problems with klcc installed on the host system
and also includes two former buildroot patches:
- nbd-fix-build-with-disable-lfs.patch
- nbd-server-fix-read-eagain.patch
These patches get removed from the buildroot tree by this patch too.

-Running ./configure with --disable-lfs #define's NBD_LFS to 0 and

Created a patch and sent it to the mailing list - compiles fine. :)
Thanks for the hint.
