Fwiw, I can't repeat, bfs_fuse builds fine here.

[diver]

This is under ubuntu 10.04.

[luroh]

I'm on Ubuntu 11.04, 32-bit. Strange.

[idefix]

I can't reproduce it either (Ubuntu 11.10, 64 bit).
Neither could the Launchpad ​Build ​Daemons.

Could it be that your fuse.cpp is corrupted?

[luroh]

Problem confirmed here on a fresh and up-to-date install of Ubuntu 10.04, 32-bit.

apt-cache policy libfuse-dev

The problem is that, on ​line 599 of fuse.cpp, FUSE_OPT_END is defined as:

{ .templ = NULL }

GCC in C++ mode trips over that period (see also ​this blog post).

This was fixed on ​2010-02-18, but apparently it didn't make it into the libfuse-dev package of Ubuntu 10.04.

A possible (temporary) solution would be to replace FUSE_OPT_END with { NULL, 0, 0 }.

[luroh]

I confirm that Idefix' solution above fixes the problem.

[diver]

This fixes for me as well.

[idefix]

The attached patch​ should also fix this bug.

[idefix]

Patch to fix building bfs_fuse on Ubuntu 10.04 LTS

[nielx]

What's the status of this patch? is it in order, or does it require a comment to note why it does the things it does?

[bonefish]

I would define FUSE_OPT_END as { }. Furthermore a comment why that is done should be added. After all this is a work-around for a broken FUSE header.

[idefix]

I defined FUSE_OPT_END as { NULL, 0, 0 }, because that's what it is in the current ​FUSE header.

But should this patch be applied? I doubt there are many who compile bfs_fuse on Ubuntu 10.04. And the ones that would like to, can always apply this patch themselves.

[nielx]

I am unsure whether or not to apply. Ubuntu 10.04 is supported throughout Q1 of 2013 (if I read the graph right), and the server version a year longer. However, it is questionable how many users of 10.04 are going to try Haiku, as being on a LTS release means they are not very experimental to begin with...

[luroh]

Diver, what do you think, time to close this one? Ubuntu 10.04 is no longer supported and bfs_fuse builds fine here on the latest LTS version.

[diver]

Sure, let's close it. I don't use Ubuntu anymore, anyway :)
